Match the other dashboards: `rgb(15, 122, 102)` instead of the brighter
`rgb(25, 158, 112)`, still clear of the separation floors against the JMeter grey.
Use `rgb(15, 122, 102)` instead of `rgb(25, 158, 112)`: the brighter step drew
too much attention for a background band.
This is the darkest teal that still separates from the JMeter grey by a readable
margin -- normal-vision dE 15.6 against a floor of 15, CVD dE 12.3 against a
target of 8, and at least 3:1 on the dark surface. Dimmer steps fail: rgb(25,
100, 90) lands at dE 9.5, and a grey-derived rgb(25, 70, 70) at dE 5.8, which is
indistinguishable from the JMeter grey even with full colour vision.
Both checks selected on {job="xrpld"}. Loki's OTLP ingestion promotes
service.name to the label `service_name` and keeps a `job` attribute as
structured metadata, which a stream selector cannot match, so the selector
returned zero streams whatever had been ingested. The collector config and
TESTING.md already say to select on `service_name`.
Invert the cross-reference. Picking an arbitrary trace from Tempo and
expecting it in Loki fails even when correlation works, because a log line
carries a trace_id only when emitted inside a sampled span and most spans
log nothing at `warning` level. Start from a logged trace_id instead and
resolve it in Tempo, which is the invariant worth asserting, and try every
id found so one unexported trace does not fail the check.
Bound the log queries in time. Nothing here set start/end, so every query
relied on Loki's one-hour default and returned nothing when re-run later to
investigate a result.
Match the other dashboards: restore `rgb(70, 70, 70)` on `Perf Runs (JMeter)`
so regions that rendered before keep their colour. `Perf Runs (Locust)` stays
aqua.
The driver split changed the existing perf-run regions from grey to violet,
which was not asked for. Restore `rgb(70, 70, 70)` on `Perf Runs (JMeter)` so
every region that rendered before keeps its colour; `Perf Runs (Locust)` stays
aqua, since it is new.
Grey separates from aqua well (dE 22.8 deutan, 25.9 tritan, 26.1 normal), but it
sits at 1.98:1 against the dark-theme surface, below the 3:1 floor, so its region
edges read faint there. Noted in the runbook.
Apply the same two-layer split as the other dashboards to the sync-health board,
which is introduced on this branch: `Perf Runs (JMeter)` and
`Perf Runs (Locust)`, each matching ["perf-iac", "<driver>"] with
matchAny:false, in place of the single generic `perf-iac` layer.
A single "Annotate perf-iac runs" layer matched only `perf-iac`, so a Locust
load window was indistinguishable from a JMeter one. perf-iac now tags every
region with its load driver, so each driver can have its own layer and colour.
- Replace that layer with `Perf Runs (JMeter)` and `Perf Runs (Locust)`, each
matching ["perf-iac", "<driver>"] with matchAny:false, on 12 dashboards.
- job-queue, ledger-data-sync and log-derived-insights had an empty annotations
list and drew no perf regions at all; they now carry the builtIn layer plus
both driver layers.
- Grafana tag matching is a superset AND with no negation, so a generic
`perf-iac` layer also matches every driver region. Keeping one alongside the
driver layers would draw each load window twice, so it is replaced, not kept.
- Document the layers in the telemetry runbook, including two rendering limits:
annotations draw only on timeseries, state-timeline and candlestick panels,
and the shaded fill is 10% opacity so the region edges carry the colour.
- Add `jmeter` to the cspell dictionary; the hook rejects the bare word.
clang-tidy runs misc-include-cleaner with WarningsAsErrors, so a symbol
reached only transitively fails CI. Add the direct includes for JLOG,
beast::Journal, StartUpType, TokenType, toBase58, std::exception and
std::size_t.
JLOG is defined in xrpl/basics/Log.h, and libxrpl.beast cannot include
xrpl.basics -- basics depends on beast, not the reverse. Use the journal
stream idiom the rest of the file already uses.
detachCallbacks() flips a flag that each observable callback checks on entry,
which leaves a callback already past that check running while the twelve
service stops below it tear down the state it reads. Stop the provider at the
same point instead: that joins the reader thread, so once it returns no
callback is running and none can start. Metrics recorded during the remaining
shutdown steps are no longer exported, which is the cost of the guarantee.
Build metricsRegistry_ in the member-init list rather than assigning it in
setup(). getMetricsRegistry() is read from the job queue and io threads, which
are running by then, so the later assignment was an unsynchronised write to the
handle those reads follow.
beast::insight instruments are created during ApplicationImp's member-init
list, and opentelemetry-cpp 1.28 never rebinds an already-vended Meter, so an
instrument created before the MeterProvider is published records nothing for
the rest of the process. Observable instruments carry the opposite constraint:
registering one arms the SDK reader thread, and its callbacks run hook handlers
that read services which do not exist that early.
Publish the provider in Telemetry's constructor, ahead of every producer, and
defer only the observables. Collector gains onCollectionReady() and
onCollectionStopping(); OTelCollector arms and disarms its gauges in response.
StatsDCollector starts its polling thread in its own constructor and had the
same hazard, so it uses the pair to gate that thread.
The metrics resource carries service.instance.id and is immutable once built,
so the node public key is resolved in Main.cpp, where a config error can still
be reported, and passed to makeApplication(). getNodeIdentity() remains
authoritative; both paths now share readNodeIdentity(), so telemetry cannot
report a key the node has abandoned.
An explicit ~ApplicationImp stops observing and stops telemetry, covering the
setup() failure paths that never reach run(). Telemetry::stop() is once-only
and no longer clears another instance's global pointer. The histogram view's
meter selector now matches the meter actually in use, so its bucket boundaries
apply for the first time.
makeTelemetrySetup() rejects a contradictory [telemetry] mutual-TLS
setup by throwing, but it is called from ApplicationImp's
member-initializer list. A try/catch in the constructor body cannot
reach a throw from there, and nothing further up the stack caught it
either, so a config mistake reached std::terminate: the default handler
printed a terminate dump and raised SIGABRT, leaving a core file
instead of a startup error.
Catch std::exception around makeApplication() in run(), report the
reason on stderr and return -1, so the failure is a clean non-zero exit
with a message an operator can act on. Only the construction is
wrapped. setup() starts subsystems whose shutdown order is delicate and
is left outside deliberately, because unwinding a half-started
Application would skip the normal stop sequence.
Gate both validation guards on enabled. A node with telemetry switched
off previously refused to start over certificate paths that nothing
would read.
Document both throws on makeTelemetrySetup(), state in
cfg/xrpld-example.cfg and the configuration reference that a partial
mutual-TLS setup is fatal and that the checks apply only when
enabled=1, and add a runbook troubleshooting entry keyed on the two
error messages.
Tests cover both guards with the message asserted so the two are told
apart, both enabled=0 paths, and the default plaintext configuration.
Companion to the same fix on phase-9. These two uses exist only on this
branch, so they survived the merge-forward: develop moved TempDir from
beast:: to xrpl:: and deleted xrpl/beast/utility/temp_dir.h.
Database.cpp already includes xrpl/basics/FileUtilities.h and already
spells TempDir unqualified at line 288, so only the qualifier was wrong.
develop moved TempDir from beast:: to xrpl::, deleting
include/xrpl/beast/utility/temp_dir.h in favour of
include/xrpl/basics/FileUtilities.h. The merge kept this branch's
references to the old API, so the tree no longer compiled: the missing
header is a fatal include, and because DatabaseConfig_test.cpp lands in
the xrpld unity blob it broke the xrpld target itself, not just the tests.
Swap the include and drop the stale beast:: qualifier on 17 uses. The
three src/tests/libxrpl/nodestore files already include FileUtilities.h
and already spell TempDir unqualified elsewhere, so only the qualifier
was wrong there. DatabaseConfig_test.cpp needed the include as well; it
sits in namespace xrpl::node_store, so unqualified TempDir resolves to
xrpl::TempDir through the enclosing namespace.
Two further uses exist only on the sync-diagnostics tip and are fixed
there rather than here.
Node identity reached the OTel resource only as service.instance.id, which is
config-overridable and carries a deployment-chosen label rather than the node's
own identity. Add xrpl.node.id, set unconditionally from the node public key
(base58, TokenType::NodePublic), so traces and metrics share a stable per-node
key independent of [telemetry] service_instance_id.
Set on the tracer resource via Telemetry::setNodeId(), called from
ApplicationImp::setup() once nodeIdentity_ is known, and on the MetricsRegistry
resource via an added start() parameter. The beast::insight meter provider is
built in TelemetryImpl's constructor, before the wallet DB exists, so its
resource cannot carry the value; that path is left for later and the attribute
is omitted rather than stamped blank.
Also drops the transform/spanidentity collector processor added in
4a361a496d: per-node identity belongs on the resource, not copied onto every
span.
Consensus spans share one deterministic, ledger-derived trace_id, so a
single trace holds spans from every node and the resource-level node id is
not a reliable per-span discriminator in stored traces.
Add transform/spanidentity to both collector configs, copying
service.instance.id onto every span as service_instance_id so TraceQL can
filter per node with the same value the $node dashboard variable already
uses on the metrics side. Wired into the traces pipeline locally and into
traces/store (after tail_sampling) on the Grafana Cloud variant.
The transitions panel used increase(...[$__rate_interval]). $__rate_interval is
defined as max($__interval + scrape, 4 * scrape), i.e. deliberately one scrape
longer than the step so rate() windows overlap and lose no counter increase.
That overlap is harmless for rate(), but this panel reads the value as a count
of discrete events, and the overlap counts each event in more than one bucket.
Measured against a log-derived ground truth of 106 syncing transitions on
devnet-otel-usw2-01 over 2026-08-11T11:05Z..2026-08-12T23:04Z, the old query
reported 111.3 at a 300s step and 133.7 at a 60s step -- the error grew to +26%
as you zoomed in, because the overlap is a larger fraction of a smaller step.
Switch to $__interval so the buckets tile exactly, and wrap in round() because
increase() extrapolates to the window edges and so reports fractional counts for
an integer counter. The same measurement now gives 106 at 300s, 105 at 60s and
107 at 900s. Every state and both nodes land within a few counts of truth at any
zoom, and the legend Total is now a meaningful figure.
Pin Min step to 1m: the real scrape interval is 60s while the datasource
declares 15s, so without a floor $__interval can fall below one sample.
Draw as bars with 0 decimals -- the value is a discrete count per bucket, and a
line implies interpolation between counts that does not exist.
Nine conflicts, resolved as follows.
src/xrpld/app/ledger/detail/InboundLedger.cpp -- kept this branch's version.
phase10 sets the span's outcome/timeouts/peer_count attributes inline at each
exit; this branch replaced that with the idempotent finalizeAcquireSpan(), called
on all four exits (init, done, give-up, destructor). Taking phase10's blocks
would have set the outcome twice against a helper documented as not overwriting
what the real exit recorded. phase10's comment explains why peer_count must not
be read in a destructor; the helper solves that structurally by taking
std::optional<std::size_t> and being passed std::nullopt from there.
src/xrpld/telemetry/MetricsRegistry.cpp -- kept metric::ledgerEconomy over
phase10's "ledger_economy" literal. This branch added the naming check that
requires constants for converted families, so the literal would regress it. Took
phase10's comment cleanup.
src/xrpld/telemetry/MetricsRegistry.h -- kept registerRotationStateGauge(), which
only exists here, and took phase10's removal of the stale task-number comment.
validate_telemetry.py -- combined both. phase10 replaced serial metric polling
with a concurrent fan-out on one shared deadline, because 58 metrics x 45 s of
additive timeout overran the CI budget; that is kept. Its target list filters on
SKIPPED_METRIC_GROUPS rather than the two literals it hardcoded, so the
sync_diagnostics group stays owned by assert_sync_diagnostics_metrics() instead
of being polled and reported twice. Both SYNC_DIAGNOSTICS_GROUP and
METRIC_POLL_CONCURRENCY are needed and both are kept.
check_otel_naming.py -- both sides extend the rule docstring. Took phase10's
fuller Rule E text (doc discovery, allow-dotted markers) and re-appended rules
I/J/K/L, which exist only here.
expected_metrics.json -- the two sides add disjoint sibling groups, so both are
kept: sync_diagnostics alongside node_health_gauges, overlay_reduce_relay,
overlay_overflow, validation_lifetime_counters and not_asserted. Both dashboard
uids are kept, giving 16 asserted uids against 16 dashboards on disk.
expected_spans.json -- kept this branch's span set, a superset that adds the
acquire phase spans, ledger.serve, txset.acquire and peer.dial, and expands
ledger.acquire's required attributes. Took phase10's description, which documents
what the totals mean, and its note on how the RPC wildcard span is created.
total_span_types and total_unique_attributes are recomputed for the union: 48 and
74, since each side's figure counted only its own spans.
Docs: took phase10's more accurate wording on what the dashboard check actually
covers, and corrected the dashboard count from 15 to 16 where the merge made it
stale.
Verified: no conflict markers remain, both JSON contracts parse, both Python
files compile, asserted dashboard uids match the dashboards on disk exactly, and
the OTel naming check reports all layers consistent.
The Operating Mode Transitions panel queried state_accounting_*_transitions
directly. Those are monotonic counters, so the panel drew a slowly rising line
and a few transitions per hour were invisible against a total in the hundreds.
It also fell off a cliff whenever xrpld restarted and the counters reset to 0,
which reads as missing data rather than a restart.
Wrap each target in increase(...[$__rate_interval]) so each point is the number
of transitions in that bucket and the series survives a counter reset. This is
what the sibling panels on the same row (Operating Mode (Time Share), State
Duration Rate) already do.
Verified against devnet-otel-usw2-01/02 over 2026-08-11T11:01Z..2026-08-12T16:23Z:
the fixed expression reports 107 and 123 syncing transitions, matching the
counter deltas, and stays continuous across the 12:07 restart where the raw
counter dropped 630 -> 1.
Brief mode flaps remain invisible on Operating Mode (State Timeline) because a
~2 s dwell cannot be captured by a 60 s scrape; this panel is the place to read
them.
This branch had already made the same corrections independently, and in
richer form, so the resolution keeps this branch's version nearly throughout:
- 09-data-collection-reference.md: this branch already documents the
state-accounting gauges as cumulative **microseconds** with an explanatory
callout, and already names `jobq_job_count` with its `jobq` group. Kept.
- telemetry-runbook.md: already carries `jobq_job_count` in both tables. Kept,
along with this branch's larger additions.
- OpenTelemetryPlan.md: kept this branch's rewritten section 9 blurb, which
describes the inventory without hardcoding counts and so cannot drift.
- consensus-health.json: kept this branch's rewrite. It deliberately removed
the four TraceQL close-time detail panels and renamed the agreement panel;
the incoming side would have resurrected them. Panel count unchanged at 26.
- integration-test.sh: this branch's unprefixed native metric names were kept,
but it still asserted `job_count`, so the `jobq_job_count` correction was
carried over. That check would otherwise always fail.
The troubleshooting step queried `job_count`, which returns no series. The
gauge is registered as `makeGauge("job_count")` but `Application.cpp` passes
`collectorManager_->group("jobq")`, so the exported name carries the `jobq`
segment. The two metric tables in this file were corrected when phase-6
merged forward; this example was missed because it sits outside the tables.
Conflict resolution kept this branch's evolution and re-applied phase-6's
fixes on top of it, rather than taking either side wholesale:
- consensus-health.json: kept the native `span_calls_total` metric name and
the `interval: 15s` and point styling from this branch; added phase-6's
`close_time_correct` PromQL filter and the NetClock axis labels. The
TraceQL boolean-regex filter stays removed and the `byRegexp` overrides
carry over. Panel count unchanged at 27.
- 09-data-collection-reference.md: kept this branch's headings, its more
detailed consensus attribute table (which already types
`consensus_round_id` as int64) and its section numbering, including the
deliberate removal of the SpanNames inventory. Carried over only the
correction that the state-accounting duration gauges are cumulative
microseconds, not seconds.
- telemetry-runbook.md: kept this branch's native metric names
(`span_calls_total`, `span_duration_milliseconds_bucket`); carried the
`rpc.request` -> `rpc.http_request` span-name fix and the `jobq_` segment
on the job-queue depth metric.
- integration-test.sh: kept this branch's `check_otel_metric` form and
carried the `jobq_job_count` correction.
The integration test asserted `rippled_job_count`, which never reports any
series, so that check always failed. `JobQueue` registers the gauge as
`makeGauge("job_count")`, but `Application.cpp` passes it
`collectorManager_->group("jobq")`, so the emitted StatsD name is
`jobq.job_count` and the exported Prometheus name is
`<prefix>_jobq_job_count`.
Corrected the same name in two runbook tables that also dropped the `jobq`
segment. `09-data-collection-reference.md` already had it right, which is why
the two documents disagreed.
Routed here rather than to the phase-10 PR where it was reported: the wrong
name is present in `integration-test.sh` on every branch from phase 6
onward, and this is the branch that introduces the file.
Left alone deliberately:
- `statsd-node-health.json` still queries the old name, but that dashboard is
deleted at phase 7 in favour of `node-health.json`
- `06-implementation-phases.md` names `job_count`, which is accurate as the
code-level makeGauge argument rather than the exported metric name
The file_storage extension was added to otel-collector-config.yaml, which
every stack mounts. That made the extension mandatory: the collector image
runs as 10001:10001 and ships no writable directory, so any stack without a
prepared volume would fail to start rather than merely lose offsets. The
workload-validation stack mounts this same config and has no such volume.
Offset persistence is only useful where logs outlive a restart. The workload
harness creates a fresh log directory per run, so it has nothing to resume
from. Move the extension, the receiver's storage reference and the extended
service.extensions list into otel-collector-filestorage.yaml, layered as a
second --config by the developer stack alone. The base config keeps
start_at: beginning, which is what actually fixes the reported defect, and
stays self-sufficient for every other stack.
Verified against the pinned collector image: the base config validates and
runs on its own with no volume mounted and still ingests a line written
before startup; base plus overlay validates, preserves the base receiver's
operators through the merge, and re-ingests that line zero times on a second
run against the same volume.
Conflict resolution, OpenTelemetryPlan/09-data-collection-reference.md
Known Issues table: kept phase-9's expanded 17-row table rather than the
incoming 4-row version, and re-applied the incoming correction to the one
row it changed. The other three incoming rows are already present in
phase-9's table, and phase-9's version is more current (jobq_job_count,
not job_count).
The rpc_requests row now says [insight] server=otel; server=statsd
reaches a collector with no statsd receiver on this branch. The section 8
Quick Reference and the fallback caveat auto-merged cleanly.
09-data-collection-reference.md contradicted itself. Section 2 presents
server=otel as the recommended transport with StatsD as a fallback, but
the Known Issues table and both Configuration Quick Reference examples
still prescribed server=statsd, which on this branch reaches a collector
with no statsd receiver and an unpublished 8125/udp.
Switch the Known Issues row and the Minimal and Production examples to
server=otel with the OTLP metrics endpoint. Keep the labelled fallback
block, and state what it actually requires: re-adding the statsd
receiver and republishing the port. Also record that StatsDCollector
applies prefix to metric names while OTelCollector does not, so the two
transports do not produce the same series.
The phase-6 copy is left alone; server=statsd is correct there.
check-otel-naming fails Rule D on this branch: ledger-data-sync.json
aggregates by xrpl_work_item, which nothing in-tree emits because
perf-iac's alloy pipeline stamps it, so it cannot be derived from
*SpanNames.h. The sibling perf-iac identities xrpl_branch and
xrpl_node_role are already allowlisted; this one was missed when the
by() clauses were reintroduced.
Add it to EXTERNAL_INFRA_LABELS alongside them. Verified by removing
the entry again, which restores the failure.
Conflict resolutions:
- docker/telemetry/xrpld-telemetry.cfg: relocation conflict. phase-9 had
already moved [insight] to the end of the file with server=otel, so the
incoming block was dropped rather than inserted. Keeping both would have
produced two [insight] sections, which merge last-wins into a single
effective section, silently reviving the bug this branch just fixed.
phase-9's per-branch service_instance_id=xrpld-devnet is preserved.
- OpenTelemetryPlan/06-implementation-phases.md: kept both corrections.
phase-9's "Tempo" is right (no Jaeger anywhere in the stack) and
phase-8's "active, sampled span" is right: Log.cpp:328 injects only
when spanCtx.IsValid() && spanCtx.IsSampled().
- OpenTelemetryPlan/09-data-collection-reference.md and
docs/telemetry-runbook.md: kept phase-9's structured-metadata LogQL.
The collector's filelog regex_parser already extracts partition,
severity, trace_id and span_id, so phase-8's inline regexp forms are
redundant, and a line filter matches the literal text in a message body.
The generated node config carried two [insight] blocks. Duplicate ini
sections do not replace one another: parseIniFile emplaces the section
name (a no-op when it already exists) and appends the lines to the same
vector, then Section::append writes each key with insert_or_assign. The
effective section was therefore server=statsd with the first block's
endpoint and service_instance_id surviving but unused.
CollectorManager selects StatsDCollector for that value, so the nodes
emitted beast::insight metrics over UDP to 8125, which has no receiver
in the collector pipeline and no published port. The script's own check
asserts that 8125 is not listening, and its insight metric assertions
fail on zero series.
Keep only the server=otel block so the config matches what the script
verifies.
This branch removes the collector's StatsD receiver and un-publishes
8125/udp, but xrpld-telemetry.cfg still selected server=statsd, so the
sample config sent beast::insight metrics over UDP to a port nothing
listens on. Phase7_taskList.md:132 lists this switch as required work.
Select server=otel and replace address= with the OTLP metrics endpoint.
Document that endpoint and prefix are informational only, since
OTelCollector records on the global MeterProvider that [telemetry]
configures and formatName() applies no prefix, and note that beast
instruments are not exported yet because the collector is constructed
before the MeterProvider is registered.
Six findings from the review of #6494 survived independent verification.
Each was checked against the branch tip, and where behaviour was in
question, against a live collector and Loki rather than from the
reviewer's claim or from documentation alone.
Plan-doc section numbering. 06-implementation-phases.md used "## 6.9"
twice: for the new Phase 8 section and for the pre-existing Risk
Assessment. Three references already pointed at 6.8.1 and none at 6.9,
and the later phases are numbered 6.8.2 through 6.8.4, so Phase 8
becomes 6.8.1 and the sequence is monotonic. Renumbering to 6.10, as
suggested on the PR, would have collided with Success Metrics.
filelog read position. The receiver relied on the upstream default
start_at=end, which skips everything a node wrote before the first poll
and reads nothing at all from a log that has stopped being written to.
Read from the beginning instead, paired with a file_storage extension so
a restart resumes at the last offset rather than re-ingesting the file.
The collector image runs as 10001:10001 and ships no writable directory,
and a fresh named volume is root-owned, so a one-shot init service
prepares the volume first. It reuses an image the stack already pulls,
adding no new dependency.
Loki log stream label. The job resource attribute did not become a Loki
index label, so the documented {job="xrpld"} queries matched nothing.
Verified against grafana/loki:3.4.2 with its default config: only
service_name and deployment_environment are indexed, and job arrives as
structured metadata, which a stream selector cannot match. Dropped the
attribute and moved the twelve queries this branch introduced to
{service_name="xrpld"}. Three further occurrences in
07-observability-backends.md originate on the phase-1a branch and are
left for a commit there.
Trace ids on unsampled spans. Logs::format emitted trace_id and span_id
whenever the span context was valid. A span dropped by the
ParentBasedSampler still carries its parent's ids, so log lines
advertised traces that were never exported and the log-to-trace link
resolved to nothing. Require the sampled flag as well, and correct the
task list and the documentation that promised the fields unconditionally.
The remaining two findings were refuted. The reported risk of signing
material reaching Loki does not hold: Logs::format already scrubs seven
sensitive fields, and there is a single write path to the log file, so
every JLOG site is covered. The suggestion to add internalLink to the
Loki derived field is not applicable, because that key is not part of
Grafana's schema.
All five TraceQL panels on this dashboard returned nothing, and did so
without any visible error: they filtered on
span.close_time_correct=~"$close_time_correct", but close_time_correct is
a boolean attribute (RCLConsensus.cpp:601 passes a raw bool), and Tempo
restricts the regex operator to string operands, so the spanset resolved
to false. With the variable defaulting to All the clause rendered as
=~".*", so the panels were empty out of the box and looked exactly like a
node with no consensus activity.
Note this is the opposite of PromQL, where an absent or empty label does
match ".*" — which is why the 17 Prometheus panels on this same board were
unaffected and the dashboard appeared healthy.
Dropped the clause from all six queries, matching phases 9 and 10 where it
is already gone. The $close_time_correct variable now filters the
Prometheus "Close Time Agreement" panel instead, which already grouped by
that label but never filtered on it, so the control stays useful rather
than becoming dead UI.
Two defects were masked behind the empty panels and are fixed too:
- "Close Time: Raw Proposals" and "Close Time: Effective / Quantized"
carried unit dateTimeFromNow over close_time_self/close_time, which are
NetClock seconds (Ripple epoch), while Grafana's dateTime formatters
expect a millisecond Unix epoch — every point would have rendered as
roughly 1970. They now plot as plain numbers with the axis labelled
"NetClock Seconds (Ripple Epoch)", and the descriptions give the
946684800 offset for converting to Unix time.
- "Close Time Vote Bins & Resolution" matched its unit and axis overrides
byName against "Vote Bins" and "Resolution", which are not field names;
TraceQL select() yields close_time_vote_bins and close_resolution_ms, so
neither override applied. Switched to byRegexp so the match holds
whichever scope prefix Grafana emits.
No panel was added or removed: the (type, title) multiset is unchanged at
22. resolution_direction keeps its regex filter, which is correct there —
it is set from a std::string whose values are exactly the variable's
increased/decreased/unchanged.
The integration test's span assertions never actually ran. check_span()
built a Tempo /api/search call with --data-urlencode but no -G, so curl
POSTed the params as a body; Tempo answers 200 and ignores the query, so
every span name looked present. Verified against a live Tempo 2.9.4: the
buggy form returns the store's total trace count for any name, including
"zzz.does.not.exist"; with -G a real name returns 1 and a bogus one 0.
Fixed alongside it: the RPC check asserted "rpc.request", which is never
emitted (ServerHandler.cpp builds "rpc.http_request"). These two had to
change together, since -G turns the bogus name from a silent pass into a
hard failure.
Also in the script: a consensus timeout logged two failures and counted
two, because a post-loop else re-reported what the timeout branch had
already reported; and three unguarded curl calls aborted the whole script
under set -euo pipefail, making the ACCOUNT_ZERO fallback dead code with
no cleanup. Guarded the curls and wired an EXIT trap to the existing
cleanup(). The trap deliberately fires only before the summary, so a
completed run still leaves the stack up as the header documents.
Docs corrections, all re-derived from code:
- span inventory heading 35 -> 38, attribute heading 83 -> 89 rows
(78 unique keys), and the section 6 header table now carries the
missing TxApplySpanNames.h row so its columns sum to the same figures
- two stale paths: ConsensusSpanNames.h is under include/xrpl/consensus/,
TxSpanNames.h under src/xrpld/telemetry/
- consensus_round_id is int64, not string (RCLConsensus.cpp sets
prevLgr.seq() + 1); the runbook's TraceQL examples now use a numeric
literal instead of an unparseable bare <round_id>
- state-accounting duration gauges are cumulative MICROSECONDS, not
seconds (NetworkOPs.cpp declares std::chrono::microseconds and
publishes dur.count() raw)
- sampling_ratio is not a config key; head sampling is fixed at 1.0 and
the shipped collector has no tail sampling, so the caveat was rewritten
- the plan blurb referenced Jaeger; this stack is Tempo
Both the CMake option and the Conan recipe default telemetry on, so the
build worked, but this workflow exists to exercise telemetry and should not
depend on a default it does not control. If that default ever flipped, the
binary would build cleanly and then every span and metric assertion would
fail for a reason no log names.
Stated explicitly, the failure mode inverts: CMakeLists.txt does
find_package(opentelemetry-cpp CONFIG REQUIRED) under this option, so a
dependency graph without it fails at configure time with a clear message.
The shared build-deps action is left alone deliberately — forcing the Conan
option there would change every other workflow that uses it.
The setting was flagged in review as unauthenticated admin access. It is
deliberate, and it matches the sibling stack in docker-compose.yml, which
carries the same two variables and the same published port with its intent
in comments. This copy had none, so the reasoning lived only in a review
thread and was rediscovered as a finding each time the file was looked at.
Viewer would break the harness rather than harden it: the validation suite
drives the Grafana API against this instance to confirm each dashboard
provisions and loads, and the dashboards and datasources come from the
read-only mounts on the same service.
Two defects reported against the harness, both confirmed.
The TPS field was computed with `bc` at scale=2, and bc omits the leading
zero: it prints ".25", not "0.25". A bare ".25" is not valid JSON, and this
was the normal case rather than an edge case — ledgers close every few
seconds, so ledger-advance over elapsed-seconds is well under 1 for any
realistic window. It survived earlier checks because those piped the file
through jq, which accepts the malformed form; Python's json rejects the whole
file. awk's %.2f always pads, so the field is now produced with awk. Audited
the other numeric fields at the same time: CPU average and memory peak
already used awk, and the p99, sample count and consensus mean are integers,
so TPS was the only one affected.
Separately, a failing attribute fetch was reported under the span's own check
name, which had already recorded the trace as found. That produced two
entries for one name, one passing and one failing, inflating the check total
and blaming the trace-existence check for a failure in a later network call.
The fetch now carries its own error handling and reports under
`span.attrs.<span>`, matching where its successful counterpart reports. It
moved into a helper rather than growing `validate_spans`, which was already
well over the line limit.
Three consecutive validation runs timed out at Step 3 with nodes stuck at
"unreachable", and the reason was not recoverable from the logs. The node
logs showed the failing nodes stopping at an identical point, immediately
after JobQueue initialisation and before the debug log is opened, with no
error text at all. The harness knew each node's pid and never used it, so a
crashed node was indistinguishable from a slow one.
The readiness loop now checks whether each node process is still alive and
fails as soon as one is not, instead of waiting out the remaining window and
burying the cause under two minutes of progress output. Liveness is not a
bare `kill -0`: an exited-but-unreaped child keeps its pid, so a zombie
answers `kill -0` and reads as alive for the whole window, which is exactly
how a crashed node came to look like a slow one.
On failure each stopped node reports its wait status and the tail of its
stdout. The status is the discriminator that was missing: 137 for a SIGKILL,
139 for a segfault, 134 for an abort, anything below 128 for a deliberate
exit. stdout is printed inline rather than left to the artifact upload,
because a node that dies before its debug log opens writes nothing else and
a cancelled run uploads nothing at all.
This is instrumentation, not a fix. The failure is not attributable to the
recent changes on this branch: the first red run touched only the two Python
files used at Steps 4 and 5, both of which run after this gate, and the same
harness passed 5/5 twice before that.
Run with no arguments the script iterated an empty list, found no
violations and printed "OK: 0 dashboard(s) passed" with exit 0 -- a clean
bill of health for reading no files, indistinguishable from a real pass.
A bare run now defaults to every dashboard beside the script, and a run
that still ends up with nothing to check exits 2 rather than reporting
success. Passing paths explicitly behaves as before.
Single-value panels carry the filtered network type in their title because
they have no legend to put it in; multi-series panels carry it in
legendFormat instead. This gauge was the only single-value panel across the
fifteen dashboards without it, so its reading was ambiguous once more than
one network type was in scope.
A validation run timed out at Step 3 with only 4 of 5 nodes proposing, and
the reason was unrecoverable afterwards. Two gaps caused that.
The node-log artifact collected `node*/debug.log` but not `node*/stdout.log`.
A node that dies before its log sink opens never writes a debug.log at all,
so stdout is the only place its reason survives — and that file is written by
the harness and read by nothing, so it went to the runner and was discarded.
The failing node's log was simply absent from the artifact.
The readiness loop also fetched each node's `server_state` and threw it away,
reporting only a count. "4/5 nodes proposing" says a node is missing but not
which one, so there is nothing to grep for even once the logs are kept. The
timeout now names each node that is not proposing along with the state it
last reported, distinguishing a node that answered with a non-proposing
state from one whose RPC port did not answer at all.
Neither change affects a healthy run: the accumulator resets each attempt and
stays empty while every node is proposing.
The alerting example env file, the contact-point provisioning header and one
runbook line still pointed at a gitignored helper script and at a rollout
phase number, neither of which ships. The contact-point header now states the
policy-tree warning inline rather than deferring to a file the reader cannot
open.
Four files conflicted.
xrpl.proto and TraceContextPropagator.h: phase-9's note is a semantic
superset of phase-8's and already carries no plan-folder pointer, so
phase-9's text is kept and nothing phase-8 said is lost.
node-health.json: the only change phase-8 makes to this file is renaming a
row that phase-9 had already deleted, so phase-9's file stands. Panel count
holds at 59 and both Validated Ledger Seq panels survive.
TESTING.md: resolved per hunk rather than by side. Phase-9's replacement of
the drifted span table and its new Grafana Cloud section are kept, and
phase-8's de-numbered "Test 3: Log-Trace Correlation" heading is taken --
keeping phase-9 wholesale would have reinstated the phase number that
phase-8 removed.
The runbook pointed at a planning document and a helper script that are
outside the shipped tree, and at a dashboard script that no longer exists,
so an operator following it hit three dead ends. The Cloud alert workflow
is now described by what it does to the tracked rules.yaml.
The integration-test sections, alert provisioning headers and a naming-check
test comment were indexed by rollout phase and task numbers defined only in
planning documents outside the shipped tree. Each now names what it covers.
These comments were indexed by task, use-case and limitation numbers that
are defined only in planning documents outside the shipped tree. Nothing
in the repository defined them, so the cross-references resolved nowhere.
Each comment now states what the code does.
Two unrelated edits had crept in. The added `.claude/` line duplicates
`/.claude`, which the same file has already carried since well before this
branch, so it never changed behaviour. Removing the root `.env.*` rule did
change behaviour: contributors lost repo-level cover for any env file
outside docker/telemetry, and the local ignore that masks this on one
machine is not part of the repo.
Restore the rule and drop the duplicate, which leaves the root gitignore
byte-identical to the parent branch.
The scoped rules added under docker/telemetry stay: they keep the three
tracked .env.*.example files visible and stop the generated Grafana Cloud
dashboards being committed, which is telemetry work this branch owns.
Two defects reported against the validation harness. Both premises were
correct, but neither suggested fix was, so the remedies differ.
Dashboard panel count: `len(dashboard["panels"])` treated Grafana row
objects as panels and skipped the panels nested inside collapsed rows, so
every dashboard was over-reported by between 1 and 10 (`log-derived-insights`
read 41 against a true 31). The check also passed unconditionally on HTTP
200, so a dashboard that renders nothing would still pass. `_leaf_panel_count`
now walks row children and the result gates the verdict. Gating on the old
top-level length, as suggested, would not have caught the case it was aimed
at: a dashboard made only of collapsed rows counts its rows and reports a
positive number while rendering nothing.
RPC latency percentiles: `LoadStats.record` appended a latency for every
outcome, including requests that never got a reply, where the value is a
time-to-failure rather than a round trip. A timeout contributed the full
receive timeout, and at the error rate a real run shows this reported p95 and
p99 of 10000 ms where the true figure was 5 ms. `record` now takes an
optional latency and the timeout path passes none. The suggestion to append
only on success was not adopted: a reply carrying `status: error` is a
completed, timely round trip whose latency is a genuine measurement, and
discarding it would throw away real data. `per_command` is now keyed off the
request counts rather than the latency map, so a command whose every request
timed out still appears in the report instead of vanishing from it, and each
entry carries a `latency_samples` count.
The runbook told operators to read a missing outcome as "never went to the
network", which stopped being true once the abort path started setting it,
and the glossary still described outcome as a two-value split.
Document all three values, where each is written, and why peer_count is
absent on the abort path. Several claims were wrong and are corrected:
- Give-up is reached at about 18s, not 21s. There is no setTimer call, so
the first timer runs immediately and the old derivation counted a wait
that does not happen.
- A live aborted rate does not imply stalled acquisitions. A clean
shutdown clears every in-flight acquire, the admin fetch_info clear does
the same, and a full job lane stops timeouts advancing so give-up cannot
fire. The runbook already said the last of these elsewhere.
- A missing outcome does not mean exactly one thing. tryDB can set failed_
and return before done() runs, exporting a span with no outcome at all.
- failed covers unusable ledger data as well as exhausting the retry
limit, so a failed span can carry timeouts=0.
- The aborted lower bound of one minute holds only on the sweep path.
- The sweep measures time since anything last asked for the ledger, not
since data last arrived.
Also fixes the mainnet verification command, which still used the old RPC
port, and drops an inaccurate claim from the config comment about which
ports the workload scripts use.
The mainnet and devnet telemetry configs are host processes sharing one
network namespace and working directory, and they agreed on every port and
both database paths. Running them together left the second unable to bind,
and running them in sequence pointed a mainnet node at a store holding the
other network's ledgers, silently and with no error.
Offset the mainnet ports by ten and name both database paths after the
network, matching what debug_logfile already did.
Also narrow the attack surface this config carried. [port_ws_public] has
no admin key, so every caller on it is a guest, and it was bound to all
interfaces on a node following Mainnet; it is now loopback, and nothing in
the repo connects to that port. [signing_support] is removed: it only
affects non-admin callers, the admin ports already grant signing to local
callers, and upstream deprecates the commands it exposes. Verified against
a running node: signing still succeeds on the admin port and is refused as
notSupported on the public one.
Every aggregation that filtered on xrpl_work_item left it out of its
sum by() grouping, so PromQL dropped the label and the xrpl_ident legend
these panels build from it rendered without the work item. 217 clauses
across the touched boards.
Perf-iac gives each work item its own set of nodes, so service_instance_id
already separates the runs and the visible effect is the legend rather
than merged series. Four clauses are the exception and aggregate across
nodes, where the grouping does real work: Convergence, Lag Behind Network
Tip and Build Version now measure spread, lag and version distribution
within one work item instead of smearing two independent clusters
together. Lag Behind Network Tip also needed its on() join key extended to
match, or two coexisting work items would fail the query outright.
The five heatmap inner by (le) clauses are deliberately untouched: an
extra grouping label would superimpose several distributions.
Also in this change:
- transaction-overview gains per-type-per-stage rate and failure-rate
panels, so all three requested dimensions exist rather than latency
alone, and its stage-rate panel picks up the filters and legend its
siblings already had.
- The acquire-duration panel splits by outcome. An aborted acquisition is
open until the sweep reaps it, so mixing it into one percentile
conflated fetch latency with time-to-abandon.
- Ledger Acquire Rate by Outcome gets the same Title Case value mapping as
its neighbour, and node-health gains the $outcome variable the two
panels now need.
LedgerReq Wait by Handler and NodeStore Read Latency (Bottleneck
Discriminator) filter on xrpl_work_item but left it out of their sum by()
grouping, so PromQL dropped the label and the xrpl_ident legend lost that
segment.
These two targets took their current form on this branch, so they are
fixed here. The other nine in this file predate it and were fixed on
pratik/otel-phase7-native-metrics, which merges forward.
The discriminator panel divides two aggregations; both sides carry the
label so their label sets stay equal for vector matching.
Nine targets across four panels filtered on xrpl_work_item while leaving
it out of their sum by() grouping. PromQL keeps only the labels listed in
by(), so the label was dropped from the result and the xrpl_ident legend
these panels build from it lost that segment.
Perf-iac runs stamp xrpl_work_item and give each work item its own set of
nodes, so service_instance_id already separates the runs; the visible
effect is the legend rather than merged series. Adding the label makes the
work item identifiable, which is the comparison these panels exist for.
NuDB Read Latency and NuDB Read Found Ratio each divide two aggregations.
Both sides get the label so their label sets stay equal and vector
matching still works.
Two comment-only notes.
MetricsRegistry.cpp: record why the app and overlay includes exist and
what they cost. They are what makes loops.txt carry
xrpld.app <-> xrpld.telemetry and xrpld.overlay <-> xrpld.telemetry, where
ordering.txt previously had telemetry strictly below both. The observable
gauges are pull-model, so their callbacks need the concrete types to
sample live state. The cycle is confined to this translation unit: no
telemetry header includes app or overlay, and all of src/xrpld builds
into one target, so there is no header or link cycle. Inverting it needs
a metrics-source interface below overlay, which is left as follow-up.
Also note loops.txt is generated and must never be hand-edited.
docker-compose.yml: state the Compose >= 2.24.0 floor. The grafana
service uses the long-form env_file mapping, which older Compose cannot
parse, and it fails for the whole file rather than that one service. The
long form is required because .env.alerting is gitignored and absent in a
fresh clone, and the short form treats a missing env file as an error.
The test carried both <xrpl/proto/xrpl.pb.h> and the bare <xrpl.pb.h>.
Both resolve to the same generated header, because the proto helper puts
the generated tree and its prefixed subdirectory on the target, so the
second include expanded to nothing behind the header guard.
The bare form arrived from merging two same-day clang-tidy commits that
added the include with different spellings. Keep the prefixed spelling,
which is what the telemetry headers and the upstream phase branches use.
An InboundLedger destroyed while !isDone() recorded recordAbort() in the
metrics but left ledger.acquire carrying only the attributes set at
construction, so an abandoned acquisition was indistinguishable from one
still in flight.
Set outcome=aborted plus timeouts on that path, and add the val::aborted
constant. peer_count is deliberately omitted: reading it goes through
Overlay, and a destructor must not depend on Overlay still existing.
The status stays Unset for an abort, because InboundLedgers::stop()
clears every in-flight acquisition, so a clean shutdown would otherwise
report errors. done() now sets Error when failed_, which is an
unambiguous failure of the operation. Success is left Unset rather than
Ok, per the OpenTelemetry guidance that instrumentation should not
assert Ok.
rpcStart, jobQueue, jobStart and jobFinish each acquired a lock without
braces, so it stayed held to the end of the function and covered the OTel
recording calls this branch added. counters_.jobsMutex and
counters_.methodsMutex are process-wide, so every worker thread starting
or finishing a job serialised on the SDK's work.
That work is not a bare atomic add: each record builds a map-backed
attribute set and takes a spin lock inside the SDK, whose backoff reaches
a millisecond-scale sleep under contention.
Brace the lock plus the state it guards, then record after it releases.
None of the metric calls read lock-protected state, so this is
semantics-preserving, and rpcEnd() in the same file already had this
shape.
The row was titled after the rollout phase its metrics came from, a number
defined only in a planning folder outside the shipped tree. Grafana shows
this title to operators, so it named something no reader could look up.
Two panel descriptions pointed at a rollout phase and task number defined
only in a planning folder outside the shipped tree. The note still names
the file and the change it is waiting on, which is the part a reader can
act on.
The catalog tagged every span with a rollout phase number defined only in
a planning folder outside the shipped tree, so the column meant nothing
to a reader of the repository. The span name and source file identify
each entry.
These comments and headings identified the feature by a rollout phase
number defined only in a planning folder outside the shipped tree, so the
label meant nothing to a reader of the repository.
The section labels carried rollout phase numbers that are defined only in
a planning folder outside the shipped tree, so they meant nothing to a
reader of the repository. The descriptive half of each label already
identifies the section.
The label carried a rollout phase number defined only in a planning
folder outside the shipped tree. The descriptive half already identifies
the section.
These comments pointed at a planning folder and at its rollout phase
numbering, neither of which is part of the shipped tree, so the
references would dangle for any reader of the repository. Each comment
now states the fact it was pointing at.
The trace_state comment pointed at a planning document that is not part
of the shipped tree, so the reference would dangle for any reader of the
repository. State the reserved-and-inert fact on its own.
The rename check rewrites a bare pre-rename binary name in any processed
doc, which turned the sampler's selector description into "against xrpld
or xrpld". Describe the fallback without spelling the legacy token.
Fixes the review findings on this PR that belong to files it owns, plus
several defects found while verifying those fixes. Findings in files owned
by upstream branches are routed there and left untouched here.
Correctness:
- tx_submitter: advance the account sequence only on results that actually
consume one (tes*, tec*, terQUEUED). tem*/tef*/tel* never reach the
ledger, so advancing left a permanent gap that every later submit from
that account inherited. Add a re-fetch hatch so a repeated non-consuming
failure cannot livelock on the same sequence, and gate the account check
on funded-ness rather than list length.
- validate_telemetry: filter spans by name before collecting attributes, so
a per-span attribute contract can no longer be satisfied by a sibling
span; require exact name equality for non-wildcard children and glob
matching for wildcards; bounds-check every returned series instead of
only the first.
- collect_system_metrics: select xrpld by argv[0] rather than a substring
match on the whole command line, which averaged in unrelated processes
and reported their RSS as xrpld's. Count genuine 0.0 CPU readings, use a
clamped nearest-rank p99 index, and record RPC latency only on success.
- benchmark: return each verdict through a named variable instead of a
command substitution, so the pass/fail counters survive and the exit gate
can fire. Scale before dividing in the percentage math, which truncated a
1.26% impact to 1.00% and cleared a 1% threshold.
- compare_to_baseline: fall back to the absolute bound when the baseline is
not positive, so a 0 -> 500 ms jump is no longer "within bounds".
- rpc_load_generator: bound each connection to one in-flight recv(), drain
in-flight requests before closing, use a nearest-rank percentile, and
report delivery shortfall so an under-delivered run cannot pass with a 0%
error rate.
Fail loudly instead of silently:
- run-full-validation: treat a consensus timeout and a missing validated
ledger as fatal infrastructure errors, and fold the orchestrator and
benchmark exit codes into the final status. A degraded cluster previously
ran a full validation pass and reported misleading downstream failures.
- collect_system_metrics: warn per empty measurement source, emit
metrics_complete, and exit non-zero instead of substituting zeros that
pass every threshold. Require GNU date with %N rather than falling back
to a per-sample python3 fork that costs more than the threshold it is
measured against.
- benchmark: distinguish "could not measure" from "exceeded thresholds",
install a cleanup trap so a failure cannot leak nodes and ports, and
report an unusable baseline as inconclusive.
- workload_orchestrator: bound subprocess communicate() and fail the exit
gate on per-phase errors.
Also pins the workload compose images to the versions the sibling stack
already uses, hash-pins the Python dependencies, restricts the validator
config template to loopback, corrects the dashboard and metric counts in
the reference docs, drops a span from the regression gate that cannot fire
under a WebSocket-only workload, and narrows the teardown pkill pattern so
it no longer matches processes that merely mention the work directory.
Verified with a full harness run against a local five-node cluster:
158 of 158 checks passed with no regressions detected.
The Telemetry Validation workflow failed with three "0 series" checks:
rpc_method_us, job_queued_us and job_running_us. All three are Histograms,
and the Prometheus exporter emits a histogram only as the
_bucket/_count/_sum triple -- the bare instrument name is never a series,
so validate_metrics() could never match it.
Evidence from the failing run (31804450127): its own metric-name dump
lists rpc_method_us_bucket/_count/_sum and no bare rpc_method_us, while
the sibling counters recorded in the same function bodies passed with 100
and 67 series. capture_timings.py, which queries job_queued_us_bucket and
job_running_us_bucket, returned real values for the acceptLedger job type
in that same run. Every one of the 10 histograms present exposes the full
triple, so all three suffixes are safe to assert.
Name them the way the exporter does, matching what the spanmetrics group
above already does for span_duration_milliseconds and what
regression-metrics.json and the job-queue dashboard already query. The
metrics stay in their asserted groups because they are genuinely
unconditional, so `not_asserted` would be wrong.
`.github/scripts/rename/docs.sh` is a migration script, not a check: the
`check-rename` workflow runs it and then fails if the tree changed. Its
rule `s@([^/+-])rippled@\1xrpld@g` rewrites `rippled` unless the preceding
character is `/`, `+` or `-`, so the backtick-quoted historical filenames
added by 3153f3ef56 (`` `rippled-*.json` ``, `` `rippled-alerts.yml` ``)
were rewritten and the check failed on both plan docs.
Refer to those historical names by their path-qualified form
(`dashboards/rippled-*`, `prometheus/rippled-alerts.yml`) instead. The
leading `/` exempts them from the rule, which is the form the rest of the
repo and the surrounding lines in these same files already use. No meaning
is lost -- the notes still record which commit renamed what.
tasks/fix-validation-checks.md was committed with the phase-10 harness and
shows up in the PR diff. tasks/ is a scratch area -- roughly forty analysis and
plan documents live there locally and none of the others are tracked, on this
branch or on develop. The file stays on disk; only the tracking is removed.
Every telemetry build instruction told the reader to run
`cmake --preset default`. No `CMakePresets.json` is tracked in the repo, and the
only preset that exists is `conan-release`, generated into the gitignored
`CMakeUserPresets.json` by `conan install`. So the documented first build step
fails before it starts, in the runbook's quick-start, its disable procedure, and
the telemetry stack's testing guide.
Replaced with the flow BUILD.md actually documents -- `conan install ..
--output-folder .` followed by an explicit `conan_toolchain.cmake` invocation --
with `-o telemetry=True` / `-Dtelemetry=ON` as the telemetry delta, and a note
that `--preset conan-release` works as a shorthand.
The harness manifests asserted things the code cannot produce and missed most
of what it does. Two assertions were failing every run, and the metric set
covered 16 of the ~41 emitted names.
expected_spans.json: rpc.process was required with rpc.ws_message as its
parent, but it is created only in ServerHandler::processRequest() on the HTTP
path, so a WebSocket-only workload never produces it -- it is now optional and
parented to rpc.http_request, and the rpc.process -> rpc.command.* edge is
skipped with the real reason instead of a coroutine-context-loss diagnosis that
was never the cause. Adds the missing rpc.ws_upgrade span, corrects four
parents (consensus.mode_change, pathfind.request, and update_positions/check,
which are children of consensus.establish rather than consensus.round), and
demotes conditionally-set attributes out of required_attributes so a healthy
run stops failing. Counts recomputed from the file: 41 span types, 62 unique
required attributes.
expected_metrics.json: 16 -> 52 asserted entries across the job-queue, RPC
method, reduce-relay, overflow and validation families, plus the fifteenth
dashboard uid. Metrics the harness workload cannot exercise -- erroring RPC,
ledger-mismatch, TxQ overflow, and the lazily-created getobject_* instruments
-- are listed in a not_asserted group the validator skips, rather than as
assertions that would fail on a healthy node.
The workflow's push trigger listed two globs matching nothing
(include/xrpl/basics/Telemetry*.h, src/xrpld/app/misc/Telemetry*), so no C++
telemetry change ever triggered validation. Replaced with the paths the code
actually lives in, including src/libxrpl/beast/insight/** for the insight
export path the harness depends on. The four inert workflow_dispatch inputs are
now labelled UNUSED rather than looking like working knobs.
Docs: the workload README described a StatsD dirty-flag mechanism under a
member name that does not exist, on a code path the harness never uses -- it
sets [insight] server=otel, so gauges export through an observable-gauge
callback every cycle. Adds the missing txq-burst phase, reconciles three
different dashboard counts, and drops "posts summary to PR", which the workflow
has no permission to do. The runbook's phase-10 section loses the last
sampling_ratio reference (not a config key), gains a Regression Gate and CI
subsection covering the gate that can fail CI, and its compose-logs command now
names the workload compose file. cmake --preset default is left for a separate
change: no CMakePresets.json is tracked, so it is wrong everywhere it appears.
Also drops the dead exporter=otlp_http key the harness wrote into every node
config, and stops capture_timings.py defaulting --profile to a profile that
does not exist.
Three doc conflicts, all inside Phase 10's own sections. Resolved by keeping
phase-9's corrections and re-applying phase-10's ownership of those sections on
top, rather than taking either side wholesale:
06 §6.8.3 — Status now says Phase 10 is implemented on THIS branch (phase-9's
copy said "not merged into this branch", true there, false here). The stale
"71 checks" enumeration and "Current Status" list are replaced by phase-9's
dynamic-count description plus a Known Gaps list that states the real reason
the rpc.process hierarchy is unassertable: rpc.process is HTTP-only, so a
WebSocket-only workload never produces it. Phase-9's CI Deliverable subsection
is carried through; exit criteria keep phase-10's tick state with phase-9's
corrected wording.
06 §6.8.3 Architecture — the automatic merge had resurrected phase-10's stale
2-node cluster prose and diagram over phase-9's 5-node correction. Reconciled
to phase-10's topology (native xrpld processes vs the containerised backend,
which is accurate) with phase-9's node count: 5 validators, and the collector
labelled OTLP + filelog rather than StatsD, which the config has never had.
Dropped the "all 26 metrics required" label in favour of the manifest.
06 §6.8.3 Key Implementation Details — two claims corrected against the code.
The StatsD m_dirty gauge fix describes a member that exists nowhere in the
repo, and the harness sets [insight] server=otel anyway, so gauges export
through an observable-gauge callback. The tx.receive attribute keys are bare
suppressed and tx_status, not dotted, and tx_status is set only on the
reject/known-bad/dropped paths, so it is absent on a successful receive.
09 §5c — kept phase-10's four-column table shape, with phase-9's corrected
counts: 40 of 41 emitted spans, 67 required attributes, 14 of 15 dashboards.
Phase10_taskList — dynamic inventory totals, the real RPC span trees, and exit
criteria ticked where the code on this branch closes them. Per-RPC timings are
recorded as not gated: regression-metrics.json defines only spans and job_queue.
Verified every hunk of the phase-10 diff falls inside a Phase-10-owned section
(06 §6.8.3, 09 §5c, Phase10_taskList, and the runbook's appended Phase 10
sections); no phase-9-owned text is modified from this branch.
The reference docs had drifted from the code in ways that break the reader
rather than merely misinform: PromQL examples that return no data, a rollback
flag that is a no-op, a sampling knob that does not exist, and two span parents
that moved. Code is treated as the truth throughout; where the code is the
defective side, the doc now records it as a known issue instead of describing
the bug as intent.
Renames the docs missed: histogram names gain the exporter's unit suffix
(ios_latency_milliseconds_bucket and four siblings), ledger_history_mismatch
gains _total, the StatsD-era quantile label gives way to le buckets,
rpc.request becomes rpc.http_request, traces_spanmetrics_calls_total becomes
span_calls_total, and the nine dotted xrpl.* span attributes are recorded as
renamed rather than left as live keys.
Re-parenting: consensus.update_positions and consensus.check are children of
consensus.establish, not of consensus.round.
Units and labels: state_accounting_*_duration is microseconds, not seconds;
cache_metrics label values are case-sensitive; object_count carries demangled
C++ type names. Nodestore read and write latency stays microseconds -- the
nanosecond accumulator change did not move the exported unit.
Adds what shipped but was undocumented: the ledger.acquire span, seven
consensus.round events, twelve span attributes, node_writes_duration_us, the
7-day validation-agreement window, the TxQ admission and reduce-relay metric
families, metrics_endpoint, and the phase-10 validation workflow.
Corrects claims that never held: 10% head sampling (it is fixed at 100%),
configurable redaction (it is unconditional), -DXRPL_ENABLE_TELEMETRY=OFF
(the flag is -Dtelemetry=OFF, default ON), FindOpenTelemetry.cmake and the
xrpl_telemetry target (neither exists), Promtail and a StatsD exporter in the
pipeline (neither exists), and Loki stream selection on job= (only
service_name is a stream label).
Phase 9 is marked complete, its provisioned alerting is attributed to the
branch that shipped it, and Phase 11 stays at zero except the one prerequisite
its code closes. Counts are reconciled repo-wide: 41 emitted span families,
15 dashboards on disk with 14 asserted, 13 alert rules in 5 groups.
Hardens the gate that let this drift through: Rule E of the naming check now
covers the reference docs, its allow-dotted marker is key-scoped and warns on
stale or empty use, a missing checked file is reported instead of silently
skipped, the test suite runs in CI, and doc paths trigger the check.
C++ and CMake changes are comment-only: three MetricsRegistry instrument names,
eight OTelCollector claims of a metric-name prefix that formatName never adds,
and the telemetry option's inverted default.
Add two Peer Quality panels reading peer_disconnect_total: Peer Disconnect
Rate, the per-second teardown rate per node, and Peer Disconnects By Reason
& Direction, the per-interval increase split by cause and by which side
opened the connection. Both sit in the existing Disconnects & Connection Mix
row beside Resource Disconnects, which counts only the resource-charge
subset and carries no reason label.
The Ledger Sync Health board already shows the same split as a window
total, so it says how much of each reason but not when. These give the
time-shaped view, letting a reason spike be lined up against a stall.
Add disconnect_reason and disconnect_direction template variables for the
two new label dimensions and wire both queries to them, so the panels
filter on every dimension their series carry.
Update the 09 reference panel column and the _a7_note panel list to name
the panels that now render this counter.
Two runbook readings were misleading in ways that hid a real devnet issue.
The Online-Delete Rotation Window row said a healthy node shows the flag
"briefly 1 once per delete interval". That is true but not sufficient:
rotation_state{metric="in_flight"} is set immediately before
freshenCaches() and cleared by RotationExposureGuard on scope exit, so it
brackets only the freshen/swap phase. Measured on devnet-otel-usw2-01/02
with online_delete=256 and ~47.4M state nodes, the flag averaged
0.159/0.135 over 9 h while the node was inside a rotation ~93% of wall
clock, because the dominant visitNodes copy phase (median 651 s of an
~785 s cycle) emits nothing. The row read healthy on a rotation-bound
node. Add a scope note with the log triplet that does measure occupancy.
The Consensus Round Duration panel gained a p99 series, so retitle both
references and say when to read it: at ~19 rounds/min a single stalled
round is one sample in several hundred, so p95 stays at the normal close
time and can dip. An 11.4 s round measured p99 13400 ms while p95 read
3400 ms against a 2900-3787 ms baseline.
Instrumenting the copy phase is tracked in RIPD-7144; the underlying
rotation defects in RIPD-7720.
The "Consensus Round Duration" panel plotted only p50 and p95. At the
devnet rate of ~19 rounds/min, a single stalled round is one sample in
several hundred, so p95 over a rate interval stays near the normal 2s
close time and the stall is invisible.
Measured on devnet-otel-usw2-02 over a 40 min window: 761 rounds, of
which exactly one fell in the 7500-10000ms bucket while the mean never
exceeded 2270ms. The histogram already records the outlier; only the
panel could not show it.
Add a p99 series alongside p50/p95 and retitle the panel accordingly.
No metric or collector change: the existing
consensus_round_duration_ms_bucket histogram already has 20 boundaries
up to 120000ms.
The Peer Disconnect Rate By Reason panel anchored its LogQL capture on
"\] ", which only matches a reason logged immediately after the [NNN]
peer-id prefix. PeerImp does not log that way: PeerImp::fail emits
"[NNN] <name> failed: <reason>" and the clean teardown emits
"close: Closed". Only ConnectAttempt::fail, which logs the bare reason,
ever matched. The panel's Timeout series was therefore connect-attempt
timeouts only, Ping Timeout was invisible, and PeerImp's own Closed was
uncounted.
Match all three prefixes and separate Ping Timeout from Connect Timeout.
Recorded as LogQL trap 11 in the runbook, alongside the other silent
failures this dashboard exposed.
Also document six overlay observability gaps found while auditing what
ping/pong and gossip traffic is actually tracked. All are pre-existing
and none is fixed here: the code fixes belong in develop-owned overlay
files (TrafficCount, OverlayImpl, PeerImp, PeerfinderManager), not on a
telemetry branch, and one of them needs a public signature change.
- 09 section 6: six known issues, each marked NOT IMPLEMENTED with
file:line evidence -- mtCLUSTER counted as unknown (overhead_cluster_*
always zero, 8 panels flatline), squelch_ignored byte counts always
zero, inbound/outbound byte-basis asymmetry plus a stale Total header
comment, ping/endpoints instrumentation absent, peer span coverage,
and PeerFinder exporting 2 of ~17 available readings.
- 02 section 2.3.2: add a Status column to the span catalog. Of 36
catalogued spans, 16 are live, 15 were never built, and 5 shipped
under different names (consensus.phase.establish became
consensus.establish, ledger.close became consensus.ledger_close,
rpc.request split into rpc.http_request/rpc.ws_message, txq.apply
became txq.apply_direct/txq.accept_tx). The catalog is a design
inventory; 09 section 1.1 remains authoritative for what emits.
- Phase9_taskList: tasks 9.14-9.17 tracking the deferred work, with
exit criteria checked only for what is actually done.
- Glossary: new Ping / pong keepalive term distinguishing ping timeout
from connect timeout. Correct the Cluster and Squelch entries, which
described behaviour the metrics cannot show.
The glossary header pointed at tasks/telemetry_terms.py as its
generator. That file is in no branch and nowhere on disk -- tasks/ is
gitignored one directory up -- so the header now states the file is
hand-maintained and gives the entry format.
Gates: check_otel_naming.py passes all 9 rules (Rule D over 555
dashboard queries, Rule E over the runbook); 19 doc anchors verified;
dashboard JSON valid with a one-line diff. No C++ changes.
Resolves the nodestore latency-accumulator conflict by keeping this
branch's API surface and applying the incoming nanosecond fix to it.
This branch had renamed storeDurationStats() to recordStoreDuration() and
given it noexcept, an explicit relaxed fetch_add, and call-frequency and
thread-safety notes. The incoming change fixed the accumulators to hold
nanoseconds so sub-microsecond backend calls stop rounding to zero. Both
are kept: the name, signature and documentation from here, the nanosecond
accumulation from there.
The incoming duplicate getFetchDurationUs()/getStoreDurationUs() pair is
dropped in favour of this branch's noexcept versions, which now read the
nanosecond members and convert on read. recordStoreDuration()'s `if (us >
0)` guard is gone: it discarded every sub-microsecond store, which is the
same rounding the incoming change removes one level up.
Also updates a MetricMacros comment that explained the zero write mean in
terms of that removed guard; the injected totals it asserts on are
unchanged.
The fetch and store duration counters converted each sample to
microseconds before adding it, so any backend call finishing in under a
microsecond contributed zero. A warm nudb read answers in a few hundred
nanoseconds, so on fast hardware every read floored and the totals stayed
at zero no matter how many reads happened -- the same loss of resolution
the microsecond report was introduced to avoid, one decade lower.
Both accumulators now hold nanoseconds, the clock's own resolution, and
convert once in getFetchDurationUs() and getStoreDurationUs(). The public
accessors, the node_reads_duration_us and node_writes_duration_us JSON
fields, and the metrics that read them all keep microseconds, so nothing
downstream changes unit. storeDurationStats() takes the raw duration
instead of a pre-converted integer so no caller can round early, and
updateFetchMetrics() scales its microsecond input to match.
FetchReport::elapsed stays microseconds: it carries one fetch, not a
total, and that is the unit it declares. The reported sum is therefore the
accumulated total minus a sub-microsecond remainder per fetch, so the two
tests that asserted exact equality between them now assert that bound.
Both had assertions that depended on how fast the host reads; the bound
holds on any hardware.

The debug-log notice on Log-Derived Insights was two grid rows taller than its
content needs, pushing the first data row further down than necessary. Rendered
the panel to confirm the markdown still fits with no clipping.
It is the first panel in the dashboard, so no other panel's stored y needed to
change - Grafana's vertical compaction closes the gap.
The dashboard's sections and panels were rearranged directly in Grafana. The
in-repo copy still carried the old arrangement, so the next replace-upload would
have undone that work.
Panel and row positions (y, and x for non-repeating panels), plus panel ids, now
come from the live copy. Ids matter because the uploader keys on them: matching
them makes an upload an in-place update rather than a reshuffle.
Repeating panels stay stored at w=12, x=0 rather than adopting the live w=24. For
a horizontal repeat Grafana ignores the stored width and lays each copy out at
24/min(N, maxPerRow), so the two are indistinguishable on screen - verified by
rendering a single-network view, where a w=12 repeat still fills the row. w=12 is
the honest description of one panel at half width.
Verified: panel and row order identical to live, rendered geometry identical at
two networks (what the live stack runs), no panel rendering with an empty column
band to its left at one through four networks, and every query, description and
panel option untouched.
Carries the layout fix to the dashboards this branch owns. A repeating panel
claims the whole row once it expands per network, so the non-repeating panel
paired beside it was pushed down while keeping its stored x=12 - rendering on
the right with an empty gap on its left.
Repeating panels now get a row to themselves, keeping w=12 so their copies still
tile two across. Single-value panels are grouped to the top of each row section
so the charts that follow pair with each other rather than being separated by an
interleaved repeat.
Verified against origin/phase9: no panel lost, every targets block unchanged,
ids 1..N, no overlaps, no rows with a left-hand gap.
A repeating panel expands into one copy per network at view time and, with
maxPerRow=2, claims the whole row. The non-repeating panel paired beside it was
pushed to the next line but kept its stored x=12, so it rendered on the right
against an empty gap.
Two changes to how the layout is planned:
- a repeating panel gets a row to itself. It keeps w=12, so its copies still
tile two across inside that row.
- single-value panels are grouped to the top of each row section, so the
charts that follow pair with each other instead of being split up by an
interleaved repeat. Without this the gaps just become wasted half-rows.
Verified per dashboard: no panel lost, every targets block byte-identical, ids
1..N, no overlaps, and no row left with a gap on its left.
Panels were appearing on the right of a row with nothing to their left. A
repeating panel expands into one copy per network at view time and, with
maxPerRow=2, claims the whole row; the non-repeating panel paired beside it was
pushed to the next line but kept its stored x=12, so it rendered on the right
against an empty gap. Thirteen rows here were affected - more than every other
dashboard combined, which is why it showed up on this one first.
Two changes:
- a repeating panel is given a row to itself when the layout is planned. It
keeps w=12, so its copies still tile two across inside that row.
- single-value panels are grouped to the top of each row section, so the
charts that follow can pair with each other instead of being split up by an
interleaved repeat. Without this the gaps become wasted half-rows.
Result: no mixed rows, no left-hand gaps, 13 paired rows and only 3 panels
sitting alone, from sections with an odd number of charts.
Verified: 54 panels before and after, no panel lost, every targets block and
description byte-identical, ids 1..N, no overlaps.
Brings this dashboard in line with the other fifteen, which were normalized
together:
- id written as 1..N so panelId deep links address a specific panel
rather than whichever one happens to sit in that position
- gridPos at most two panels across; every visualisation h=10. Three
panels sat at w=8, the only three-across row in the set.
- line charts lineWidth=1, fillOpacity=0, pointSize=5, gradientMode=none
- repeat xrpl_network_type (horizontal, maxPerRow=2) with a
[$xrpl_network_type] title suffix on the stat and bargauge
panels, where two networks overlaid in one panel reads as
noise. Charts keep their networks as separate series.
The nine existing row groups are kept as they are. The heatmap already carried
the full plugin option set, so it is untouched.
Raw-text edits, so untouched lines keep their formatting byte for byte.
Verified: 54 panels before and after, no panel lost, every targets block and
description byte-identical, ids 1..N, and no two panels overlapping.
The GetObject Request Size Distribution heatmap, added on this branch, was
missing calculate, color and cellGap. Grafana's heatmap plugin needs them, and
without them the whole dashboard opens with "An error occurred within the
plugin" instead of rendering.
Same values as the other four heatmaps fixed upstream, taken from the one that
renders correctly on Grafana Cloud. The panel keeps its own axis label and unit.
Every heatmap carried only `tooltip` and `yAxis`, missing `calculate`, `color`
and `cellGap`. Grafana's heatmap plugin treats those as required, and without
them the panel fails to initialise: the dashboard opens with "An error occurred
within the plugin" rather than a chart.
The option values are taken from the one heatmap in this stack that does render
on Grafana Cloud (ledger-sync-health): calculate=false since the queries already
return histogram buckets, the Turbo 64-step scheme, and cellGap=1. Each panel
keeps its own yAxis label, unit and tooltip settings.
This is a long-standing defect rather than fallout from the recent layout work -
the same options are absent in origin/phase9 and in the cloud copies that were
already live.
Carries the sizing fix through to the dashboards this branch owns, after the
live Cloud copies showed charts clipping their legends at h=8 and stats too
cramped at h=4.
Every visualisation is h=10; tables and logs h=12; the log-derived-insights
instruction banner h=12 for its prose. A single height per visualisation also
means any two panels pair cleanly side by side.
Repeat stays on single-value panels only. The five state-timeline and heatmap
panels that had picked it up in an earlier pass are cleared, since repeating a
timeline broke ledger-data-sync on Cloud.
Verified against origin/phase9: no panel lost, every targets block unchanged,
ids 1..N, no grid overlaps.
Two problems showed up once these dashboards were live on Grafana Cloud.
Panels were too short. Charts at h=8 clipped their legends mid-row, and stats
at h=4 were cramped. Every visualisation is now h=10, with tables and logs at
h=12; the log-derived-insights instruction banner keeps h=12 for its prose.
Uniform height also means any two panels can pair side by side.
Repeat on a state-timeline broke the dashboard outright: ledger-data-sync
failed to open on Cloud at v45 and had to be restored to v44. Repeat is now
limited to single-value panels (stat, gauge, bargauge, table). Charts show
their networks as separate series instead, which is what a chart is for.
Repeat was also sticky: normalization only ever added the keys, so a panel that
picked them up in an earlier pass kept them even after its type stopped being
eligible. The keys and the title suffix are now removed from ineligible panels,
which is what actually cleared the two timeline panels here.
Verified per dashboard: no panel lost, every targets block byte-identical, ids
1..N, no grid overlaps, and repeat present only on stat/gauge/bargauge.
Applies the guideline-8 ordering to the two dashboards introduced on this
branch, and clears the last two labelling gaps found while auditing the set:
- peer-quality, validator-health: stats and bar gauges now lead their row
section instead of trailing the charts, matching the other dashboards.
- node-health "Peer Disconnects (Resources)": had an empty axisLabel, the
only chart in the set without one. Now reads "Disconnects".
- rpc-performance row "Aggregate RPC (all commands)" -> "(All Commands)",
the one title that was not in Title Case.
Reordering stays inside each row section so no panel changes category, and the
panel objects are cut and re-spliced as raw text, so their contents are
byte-identical. Verified against origin/phase9: no panel lost, every targets
block unchanged, ids 1..N, and every row section now leads with its
single-value panels.
Guideline 8 asks for gauges and stats at the top. Seven dashboards had them
scattered below charts, so the reader met a wall of time series before the
at-a-glance numbers that give those series context.
Stats, gauges and bar gauges now come first within each row section. The move
is deliberately scoped to inside a section: shifting a panel across a row
boundary would change which category it belongs to. Panels keep their relative
order otherwise, so the reading sequence within each group is unchanged.
Whole panel objects are cut and re-spliced as raw text, so their contents stay
byte-identical and only gridPos and id are recomputed. Verified per dashboard:
panel count unchanged, no panel lost, every targets block byte-identical, ids
still 1..N, and no row section left with a stat below a chart.
Applies the same normalization the phase-7-owned dashboards received, to the
five introduced on this branch: fee-market, job-queue, log-derived-insights,
peer-quality and validator-health.
- id written as 1..N so panelId deep links address a specific panel
rather than whichever panel happens to sit in that position
- gridPos at most two panels across; charts h=8, stats/gauges h=4,
tables/logs h=12 full width. Panels pair only with an
equal-height neighbour, so no row keeps a ragged empty cell.
validator-health and peer-quality were stacked single-file at
full width, which is why they were the longest to scroll.
- line charts lineWidth=1, fillOpacity=0, pointSize=5, gradientMode=none
- repeat xrpl_network_type (horizontal, maxPerRow=2) with a
[$xrpl_network_type] title suffix on stat/gauge/bargauge/
table/state-timeline panels, where two networks overlaid in
one panel reads as noise. Line charts keep their networks as
separate series.
- decimals 0 on panels counting discrete things (peers, quorum,
connection mix) - a fractional peer count is meaningless.
- rows category rows added to fee-market, job-queue and peer-quality
Panels with a right-hand legend stay full width; a side legend needs the room.
Raw-text edits, so untouched lines keep their formatting and escaping byte for
byte. Verified per dashboard against origin/phase9: panel count unchanged, no
panel lost, every targets block byte-identical, descriptions unchanged, ids
exactly 1..N, and no two panels overlapping on the grid.
These dashboards were hand-authored over time and had drifted apart: panel
heights spanned ten different values, nine dashboards had no row grouping,
line-chart styling was inconsistent, and no panel carried an id, so Grafana
assigned them positionally at load and every panelId deep link was only as
stable as the panel order.
Per panel, in document order:
- id written as 1..N so panelId links address a specific panel
- gridPos quantized to at most two panels across: charts h=8,
stats/gauges h=4, tables/logs h=12 full width. Panels are
paired only with an equal-height neighbour, so no row is left
with a ragged half-empty cell.
- line charts lineWidth=1, fillOpacity=0, pointSize=5, gradientMode=none
- repeat xrpl_network_type (horizontal, maxPerRow=2) with a
[$xrpl_network_type] title suffix, on the panel types where
overlaying two networks in one panel reads as noise
(stat/gauge/bargauge/table/state-timeline). Line charts keep
their networks as separate series, which is the point of a
line chart.
- decimals 0 where the value counts discrete things (threads, peers,
queue depths); a fractional thread count is meaningless.
- rows category rows added where a dashboard had none
Panels whose legend sits on the right stay full width: a side legend needs the
horizontal room, and squeezing it to half width clips the series names.
Edits were made as raw-text replacements, not a json.dump round-trip, so
formatting and escaping of untouched lines are byte-identical. Verified per
dashboard: panel count unchanged, every targets block byte-identical, all
descriptions unchanged, ids exactly 1..N, and no two panels overlapping on the
grid. The repo dashboard lint and the OTel naming check both pass.
Four defects found by a query-correctness audit of all 16 dashboards, all
scoped to panels this branch owns.
job-queue "Current Job Latency (p99 Gauge)": the histogram by-clause dropped
service_instance_id, collapsing every node into one fleet-wide p99 and hiding
a slow node. Measured: gauge read 1325us while the worst node was 1868us. The
panel's displayName already referenced service_instance_id, so it was also
rendering an empty label. Now groups by service_instance_id and xrpl_work_item,
matching sibling panels 5, 6 and 7.
ledger-data-sync "NodeStore Read Latency (Bottleneck Discriminator)": replaced
clamp_min(<denominator>, 1) with (<denominator> > 0). clamp_min clamps the
value, not just the zero case, so any node reading below 1/s got a fabricated
denominator. Demonstrated with a zero-rate denominator: clamp_min invents
40.2/40.3/11.2/9.2 where the > 0 guard correctly returns no data. This panel is
the bottleneck discriminator, read during a stall, which is exactly when the
read rate collapses and the clamp is most wrong. Panels 21 and 23 carry the
same defect but originate on phase-7 and are fixed there.
node-health thresholds: percentunit fields are compared against the raw value,
so a step of 80 needed 8000% and could never fire. Rescaled panels 74, 81 and
85 to 0.8. Panel 81 is a found-ratio where high is healthy, so its bands were
also inverted. Note these three panels use palette-classic with thresholdsStyle
off, so the steps are currently dormant rather than visibly wrong.
node-health panels 81 and 85 descriptions: both described the multi-series
panels they were split from. Panel 81 carried a byte-identical copy of panel
80's text, promising three plotted rate lines where it draws a single bounded
ratio; panel 85's text described read-thread gauges absent from its expression.
Rewritten to match the actual queries.
The Transaction Overview panel "Queue Bypass Ratio (Direct Apply vs
Enqueue)" reported a confident 0.50 on every node while the true bypass
rate was zero. The two spans it divided are not disjoint alternatives:
txq.apply_direct is a child of txq.enqueue. TxQ.cpp creates the
apply_direct span as the first statement of tryDirectApply(), ahead of
the account, sequence and fee-level guards, and tryDirectApply() is
called from inside the live enqueue scope. The span therefore counts
attempts, so the denominator direct + enqueue counts each transaction
twice and pins the ratio to one half algebraically.
Measured on a four-node fleet: 6082443 direct against 6082877 enqueue
over the same population, panel output 0.5000170 on three nodes and
0.5000000 on the fourth. Grouping txq.enqueue by txq_status over seven
days returns only "rejected" -- no transaction has ever taken the
direct-apply path.
Remove the panel rather than repoint it. A correct expression using
txq_status as the disjoint discriminator would render permanently
empty on this fleet, which reads no better than a wrong number.
Widen the band partner "TxQ Enqueue Rate by Transaction Type" from 12
to 24 columns so the y=48 band still fills the grid. Every band in all
ten dashboards sums to 24 columns; leaving a half-width hole would be
the only exception. Panel order and every other panel's position,
width and height are unchanged.
The runbook already listed txq.apply_direct as available but not
paneled, so that row becomes accurate. Rows describing the span itself
are untouched -- the span and its metric are unchanged.
Panels 21 (NuDB Read Latency) and 23 (NuDB Read Found Ratio) on the
Ledger Data & Sync dashboard guarded their divisor with
clamp_min(<denominator>, 1). clamp_min raises the value, not just the
zero case, so any node reading fewer than 1 block per second was
divided by a fabricated 1 instead of by its real read count.
Replace the clamp with the filter (<denominator> > 0). A comparison
without the bool modifier drops the sample rather than rewriting it, so
these panels now show no data instead of a wrong number.
Measured over 7 days: five nodes fall below 1 read/s. On validator-0 the
clamp reported 2.726 us/read against a true 5.493, and on nonUNLmalloc-tc
it reported 0 us/read, which cannot occur. The error is largest exactly
when panel 21 is used as the bottleneck discriminator during a stall,
because that is when the read rate collapses toward zero.
Matches the existing idiom on the same nodestore_state metric family in
the NodeStore Write vs Read Latency panel.
Grafana 13 enables the renderAuthJWT feature toggle by default, so the image
renderer silently drops render requests carrying the default token and alert
notifications arrive with no panel image. The runbook's alerting section
covered delivery but not this failure mode.
Adds how the token is wired (one variable feeding both services, so they cannot
drift), how to override it, and the two-command check for when images stop
appearing.
The renderer was the only service in the stack on a floating :latest tag, so
the stack was not reproducible: a renderer release could change under a
checkout that had not been touched. Pins it to v5.12.0, matching how every
other service here is pinned.
Also wires the shared render token. Grafana 13 enables the renderAuthJWT
feature toggle by default, and the renderer rejects requests unless both sides
present the same non-default token, so pinning alone would leave rendering
broken once the Grafana bump merges forward. Both values come from the same
GF_RENDERING_RENDERER_TOKEN variable and cannot drift apart; the local default
keeps `docker compose up` working with no setup.
Verified `docker compose config` resolves and both AUTH_TOKEN and
GF_RENDERING_RENDERER_TOKEN expand to the same value.
Bumps the Loki pin this branch introduced, and updates the two docs that
name the version so they do not drift from the compose file:
- OpenTelemetryPlan/09-data-collection-reference.md (log backend section)
- OpenTelemetryPlan/Phase8_taskList.md (compose snippet)
The service runs the config bundled in the image rather than one from this
repo; `-verify-config` reports "config is valid" under 3.7.6, and native OTLP
ingestion at /otlp is unchanged across 3.4 -> 3.7.
Moves off the v2.53 LTS line, which this branch pinned, onto the current
v3 release, and corrects the accompanying comment that named the old line.
Verified against the new image rather than assumed, since this crosses a
major version:
- prometheus.yml passes `promtool check config` under v3.13.2
- all 391 unique dashboard PromQL queries parse under the v3 parser
- all 13 alert-rule expressions parse under the v3 parser
The config uses none of the surfaces v3 changed: no remote_write, no
holt_winters, no offset modifiers.
Bumps the three images this branch pins:
otel-collector-contrib 0.121.0 -> 0.158.0
tempo 2.7.2 -> 2.9.4
grafana 11.5.2 -> 13.1.2
Verified locally against the new images: the collector config passes
`validate` under 0.158.0 and tempo.yaml passes `-config.verify=true` under
2.9.4, both unchanged. The collector's log path uses the generic otlphttp
exporter (otlphttp/loki), not the dedicated loki exporter removed upstream in
v0.147.0, so the pipeline is unaffected by that removal.
Grafana crosses two majors. Operator-visible consequences are handled on the
branches that own the affected files: Grafana 13 enables the renderAuthJWT
feature toggle by default, so the image renderer now requires a matching
renderer_token on both the server and the renderer container.
The Mainnet telemetry config carried ssl_verify=0, inherited when the file
was copied from the Devnet config. Mainnet fetches its validator lists from
public HTTPS publishers (vl.ripple.com, unl.xrplf.org) that present valid CA
certificates, so there is no self-signed certificate to work around.
With ssl_verify=0 both halves of TLS peer authentication are skipped on those
fetches: the certificate chain check and the RFC 6125 hostname match. The list
blob's own signature is still verified against the pinned publisher keys, so
this restores defense in depth rather than fixing a validator-injection path.
Restores the secure default and documents why it stays that way.
develop renamed CamelCase namespaces to snake_case with no compatibility
aliases, so lines this branch added still referenced the old names. The
merge was textually clean because develop never touched those lines, which
left the breakage invisible to git and visible only at compile time.
PeerFinder:: -> peer_finder:: Overlay.h, OverlayImpl.h, MetricMacros.cpp
Tuning:: -> tuning:: PeerImp.cpp (the other call sites in this
file already used the lowercase form)
Two further merge artifacts:
json_value.h develop added `using value_type = Value const` to
ValueConstIterator, and this branch had added
`using value_type = Value` for the same reason, so the merge
kept both and they redefined the alias with different types.
Keep develop's const-qualified type -- correct for an
iterator whose reference is `Value const&` -- and keep only
this branch's iterator_category addition.
InboundLedger.h <string> is no longer used directly by the header, but
five translation units that include it use std::string
without including <string> themselves. Mark it
`IWYU pragma: keep` rather than remove it, matching
suite_list.h.
develop renamed xrpl::Resource to xrpl::resource. MetricsRegistry.cpp
declared `namespace resource = opentelemetry::sdk::resource` at file
scope, but both use sites are inside namespace xrpl::telemetry, where
inner-scope lookup finds the enclosing xrpl::resource first and never
reaches the alias. That namespace has no ResourceAttributes or Resource,
so the build failed on all four platforms:
error: no type named 'ResourceAttributes' in namespace 'xrpl::resource'
error: no member named 'Create' in namespace 'xrpl::resource';
did you mean 'creat'?
Rename the alias to otel_resource. Moving it inside xrpl::telemetry would
also compile, but only by shadowing xrpl::resource -- a reader at the use
site still could not tell which namespace `resource::` meant, and a later
using-directive would reintroduce the ambiguity. A distinct name removes
the collision by construction and matches the metric_sdk / otlp_http
aliases already in this file.
Rule D validated every dashboard label against L1 (*SpanNames.h) and L6
(MetricsRegistry) labels. LogQL labels have a third provenance neither
layer can resolve: they are minted by the collector's regex_parser named
captures (partition, severity) or by an in-query `| regexp` stage
(action, pk, state, mode, phase, jobname, ip, pubkey). Checking them
against L1/L6 reported ten violations for labels correct by
construction.
Make the rule datasource-aware instead of allowlisting a filename. The
dashboard JSON is parsed so each query can be attributed to its
datasource, and queries on a log datasource are skipped. The exemption is
per query, not per file, so a dashboard mixing Prometheus and Loki panels
still has its Prometheus panels validated.
Parsing the JSON also fixed a blind spot: label filters are stored with
backslash-escaped quotes (`label=~\"$v\"`), which the previous raw-text
regex could never match, so only the `sum by (...)` form was ever
checked. With the strings unescaped, 555 queries are now validated where
far fewer were before. That surfaced three legitimate label sources the
rule did not model, each fixed at its source rather than allowlisted:
- deployment_environment / xrpl_network_type: resource attributes the
collector promotes onto metric datapoints. Derived from the config's
resource_metrics_key_attributes, so a new key is picked up
automatically, in both dotted and underscore forms.
- resource.service.instance.id: strips to a dotted service-identity
key, which builtins only held in underscore form.
- name: the TraceQL span-name intrinsic, alongside duration and kind.
A file that does not parse falls back to the raw-text scan, which checks
every query rather than skipping it; JSON validity is already enforced by
the prettier pre-commit hook.
Adds 10 tests: the exemption, per-query scoping in a mixed dashboard,
target-inherits-panel datasource, no sideways inheritance leak, nested
row panels, TraceQL intrinsics, the malformed-JSON fallback, and the
collector-promotion helper.
09-data-collection-reference.md: keep phase-9's structure, which relocated
the §2a call-site-metrics content into §5b (3860c93db2). The incoming §2a
block is superseded; its snake_case namespace fix is already applied to
phase-9's copy of the same text.
The stat block was relaid two-per-row in the previous commit, but the reflow
shifted subsequent panels by a delta computed against the block's old height.
The block shrank, so the delta left a 12-grid-line dead band between the stat
row and "Node Operating State Transitions".
Recompute every panel's y by walking the list in order and pairing half-width
panels, rather than patching offsets incrementally. The layout is now derived
from panel order and heights, so this class of drift cannot recur.
Verified: 192 grid lines, fully covered, no empty band, no overlaps, and no grid
line occupied by more than two panels.

Fixes found while validating the Log-Derived Insights dashboard against live
Loki and Tempo. Every change was verified by executing the query, not by
inspection.
loki.yaml — the ConsensusLedgerHash derived field never matched anything:
- The TraceQL query named `.xrpl.consensus.ledger_id`. The attribute is
`consensus_ledger_id` (ConsensusSpanNames.h); live Tempo lists no dotted or
xrpl-prefixed variant among its span attributes.
- The bare `.` intrinsic scope cannot match a span attribute regardless of
name; TraceQL requires `span.`.
Corrected to `{span.consensus_ledger_id="..."}`, which returns the expected
consensus.round trace for a real ledger hash.
log-derived-insights.json:
- Stat units `suffix: <noun>` rendered raw integers, so large values printed
in full. `si:<noun>` is unsafe because Grafana parses the leading letter as
an SI prefix (`si:fee` rendered "29.0 Mee"). Switched to `short`, the
convention already used by 42 panels; the noun is in each panel title.
- Stat panels showed a single fleet-wide tile labelled "Value #A". Grafana's
Loki backend does not name binary-operation frames from legendFormat, so the
ratio panel could not resolve per-node labels. Replaced it with a plain sum
of duplicate fetches; the ratio remains available as a timeseries. Added an
explicit legendFormat to all eight stat panels.
- The ledger-fetch regex required `good:N dupe:N` together, but
SHAMapAddNode::get() omits any zero counter. That dropped 32% of lines --
disproportionately the efficient fetches -- biasing the ratio upward. Each
field now matches independently.
- state-timeline used `spanNulls: true`, which spans gaps indefinitely and
would render an outage as continuous. Set to the 30-minute threshold.
- Stat panels relaid two-per-row and given a tooltip, per dashboard guidelines.
telemetry-runbook.md:
- LogQL examples used line filters where structured metadata exists.
`|= "ERR"` also matches the literal in a message body: measured 423 ERR
lines plus 4 DBG lines per 6h. Replaced with severity, partition, and
trace_id field filters.
- Documented the new dashboard, its debug-log requirement, and the LogQL traps
these fixes exposed.
- Corrected the dashboard count, which was already stale at eleven against
fifteen on disk, and named the six with no reference section.
The heading still read "Future:" while the section body documents the
validation suite this branch ships and gives commands to run it. Section 6.8.3
in 06-implementation-phases.md already drops its "Future Enhancement" marker
here; this makes 5c consistent with it.
The Phase 7 section existed twice in this file; the copies disagreed on this
one label. Consolidating on the single copy kept the older wording, but Jaeger
was removed from the project earlier in this chain, so Tempo is the only trace
backend the diagram should name.
These changes were developed on the phase-10 branch but belong to content this
branch and its upstreams introduced. Carrying them on phase-10 made its PR diff
report churn in files phase-10 does not own, and left each PR claiming a scope
that did not match its contents.
Moved here from phase-10 (identical content, no functional change):
- Dashboards: all 14 existing boards plus the new log-derived-insights board.
- Docs: telemetry-runbook.md (minus the workload/benchmark sections, which
describe phase-10 tooling) and the new telemetry-glossary.md.
- Grafana Cloud + Alloy export path: collector config, compose override, the
two .env examples and alloy/config.alloy.
- Local stack: otel-collector-config.yaml gains sub-millisecond and
second-scale spanmetrics buckets, pins unit=ms, and promotes
close_time_correct; integration-test.sh and TESTING.md follow.
- Node configs: exported_instance -> service_instance_id in comments; the
mainnet sample now logs at warning to bound log volume.
- Metrics code: Telemetry.cpp builds the metrics pipeline in the constructor
via initMetrics() so the global MeterProvider is published before any
subsystem creates a beast::insight instrument, and the histogram view keeps
each instrument's own name instead of collapsing them under one series.
MetricsRegistry gains a last_close_time gauge and skips negative job-queue
durations. OTelCollector drops an unused accessor.
- Naming CI: xrpl_work_item joins EXTERNAL_INFRA_LABELS and Rule E accepts the
dotted perf-iac resource-attribute form. This must travel with the
dashboards and runbook that reference those labels, or the rules fail.
- Doxygen input glob no longer recurses dot-directories.
Sections describing phase-10 tooling stay on phase-10 and keep their
"Future Enhancement" / "Planned, not yet implemented" markers here; phase-10
removes those markers when it lands the tooling.
Update the catalogue table and prose for the two thresholds corrected by the
7-day backtest, and document why ValidatedLedgerStale must exclude the
1209600s sentinel that getValidatedLedgerAge() returns when no validated
ledger exists — that clause looks redundant and would otherwise be removed
as a simplification.
Also record the tuning lesson: justify thresholds from a 7-day sample, not
24 hours.
ValidatedLedgerStale fired on every node, healthy included.
LedgerMaster::getValidatedLedgerAge() returns weeks{2} (1209600s) as a
SENTINEL when no validated ledger exists, not as a measurement. The rule
read that as "14 days stale". Measured over six days it produced sustained
firing on all nine nodes. Excluding the exact sentinel value drops that to
zero while still tracking real staleness.
ManifestFloodInbound at 50 kB/s was routine paging: ~41 sustained 5-minute
samples across six healthy nodes in six days. Healthy p99 is 1.0-1.8 kB/s
and real storms peak at 2.7 MB/s, so 512 kB/s sits ~280x above normal and
~5x below the peaks, cutting sustained samples to 2.
Both thresholds were previously justified from a 24-hour window, which was
too short to expose either problem.
Correct the dashboard count (11 -> 15), note which boards lack a reference
section, and update the log-derived-insights panel/row counts. Replace line
matches with structured-metadata filters in the LogQL examples and document
the PeerFinder debug requirement plus which [MIXED] panels work at the
default log level.

Bound the number of manifests carried in a single TMManifests message
(kMaxManifestsPerMessage). Trusted manifests are always included and
processed; untrusted gossip is capped per message on both send and
receive, and the sender is charged only when untrusted entries are
actually skipped. Oversized TMManifests messages are dropped without
penalty at the protocol layer so an unpatched peer is not disconnected.
Complements the cache bound from #276/#323.
Forty-eight panels spread over seven dashboards used the standard
description template but stopped after Function, leaving out Keywords,
Computation boundary and References. ledger-data-sync was the worst at
33 of 35 panels. They read as half-written next to their complete
neighbours, and the Keywords section is what defines the domain terms a
reader needs.
Fill in the three sections for each, in the order the already-complete
panels use. Keyword text is chosen from the panel's own metric family
rather than written per panel: job_* panels get the job-type and
deferred-job definitions, getobject_* and nudb_* get GetObject and
NodeStore, peer_finder_* and the traffic counters get peer and overlay,
and span-derived panels state that the value comes from the SpanMetrics
connector rather than a native metric.
Every panel now carries all ten sections. Panel count, layout, units and
queries are untouched.
Thirty-nine panels on this dashboard carry the full ten-section
description; twelve did not, so they read as half-written next to their
neighbours.
Eleven of them used the template but stopped after Function, missing
Keywords, Computation boundary and References. Fill those in, placed in
the same order the complete panels use. Content comes from each panel's
own metric: the job-queue panels get the job-type and deferred-job
definitions, I/O Latency and Database Sizes get the scheduler and
NodeStore ones, and each states whether its value is a native
beast::insight metric or computed through the OpenTelemetry SDK.
Server State had no template at all, only a one-line summary. Rewrite it
in full, documenting the 0-4 operating-mode encoding and its colour
mapping, and noting that it is an instantaneous state rather than a rate.
Panel count, layout, units and queries are untouched.
Three dashboards had layout faults that Grafana renders as visible
artifacts.
On Node Health, two row headers carried the same title as the panel
directly beneath them -- "Cache Hit Rates" and "Object Instance Counts"
each appeared twice, once as a row bar and once as a panel. Rename the
rows to "Caches" and "Object Instances"; the panels keep their names.
Worse on the same dashboard, seven bands summed to 48 columns on a
24-column grid, because the Extended Metrics block reused the y-space
already occupied by NodeStore I/O. Grafana cannot lay that out
deterministically, which is what produced the artifacts.
RPC Performance and Transaction Overview each had blank bands -- one
row and eight rows respectively -- left behind by earlier panel moves.
Repack all three grids so every band fits 24 columns, each band starts
where the previous one ends, and rows stay full-width single-height
anchors. Panel order, panel count and every panel's own width and
height are unchanged; only position moves.
Brings the telemetry startup-ordering fix forward. Two conflicts, both in
the metrics registry.
initSyncInstruments(): this branch had already replaced the registry-owned
state_changes_total with a call-site macro carrying {from,to} labels, and
the arriving branch moves the jq_trans_overflow_total observable out of
this function into registerJqTransOverflowCounter() so it is armed with
the other pull-model instruments. Kept both: the explanatory comment for
state_changes_total stays, the inline overflow block goes. The arriving
stateChangesCounter_ creation is dropped rather than merged -- this branch
removed that member, so keeping the line would not compile.
Test file: kept this branch's fuller header documentation, which records
what the disabled build can and cannot assert for the sync-diagnostics
gauges, and folded in the arriving branch's one new fact, that the
lifecycle is now two-phase. Include lists unioned.
Resolves the telemetry-startup conflict between the two branches. Both
sides move the telemetry start earlier in setup(); they disagree only on
how far the pipeline had been split at that point.
phase-1b (arriving) moved nodeIdentity_, setServiceInstanceId() and the
telemetry start up to just after the wallet DB is proven usable. phase-9
had split the metrics pipeline in two and left its copy of that block at
the old, later position.
Kept both intentions: the block stays at phase-1b's early position, and
metricsRegistry_ construction moves up with it so it precedes
startTelemetry() -- the metrics half is guarded on the registry existing,
so leaving the construction behind would have started tracing while
silently skipping metrics. phase-9's later copy is dropped as the stale
duplicate. The two-phase split is preserved: startTelemetryGauges() still
runs after overlay_ is constructed, because the observable callbacks read
it and getOverlay() asserts.
Net effect is that the metrics provider now starts earlier than on either
branch, and still before beginConsensus() emits the first spans and the
only operating-mode transition.
Sixteen bargauges on ledger-sync-health are titled "... (Count ...)" and their
descriptions promise a count over the selected time range, but the queries
used last_over_time(counter[$__range]). For a monotonically increasing counter
that returns the newest cumulative sample -- the lifetime total -- so every
panel read the same number no matter how the time picker was set. Verified
live: dns_resolve_total over [15m] and [24h] both returned 12/5.
Switches the 17 affected targets to increase(), which is the range-scoped
delta the titles and descriptions already describe.
Panels: DNS Resolve Outcomes, Outbound Dial Outcomes, Handshake Negotiation
Failures, UNL Fetch Outcomes, Server Stall Episodes, Acquire Stalls, Acquire
Source, Inbound Peer Accept Outcomes, Peer Disconnects, Ledger/Object Serve
Refusals, Byzantine Ledger Jumps, Replay Fallback, Replay Outcomes, Pre-Accept
Quorum Shortfalls, Sweep Heap-Trim Faults, Rotation Node Re-Stores.
Two live-verified dashboard defects found while auditing the devnet nodes.
Sub-millisecond spanmetrics buckets. The ladder started at 1ms, but most
xrpld spans are far below that: tx.preflight means ~0.012ms and tx.preclaim
~0.15ms. On the live nodes the first bucket held 13,761,009 of 13,761,419
tx.preflight samples (99.997%), so histogram_quantile pinned every p95/p99
at a constant 0.95ms and ~10 latency panels reported a boundary artifact
rather than a measurement. Adds 0.01/0.05/0.1/0.25/0.5ms ahead of 1ms in all
three bucket lists, which must stay identical or the connector misbuckets.
consensus_mode filter on spans that never carry the label. Only
consensus.round and consensus.ledger_close are stamped with consensus_mode
(verified against live series), so panels 1, 3, 12 and 14 -- which query
consensus.validation.send, consensus.proposal.send and
consensus.accept.apply -- blanked as soon as an operator picked any value
from the Consensus Mode dropdown. Drops the selector from those four; ids 2
and 11 keep it because their spans do carry it.
Note: existing histogram series retain the old le boundaries, so
span-latency panels show a discontinuity at collector restart.
base_fee_xrp was observed from LoadFeeTrack::getLocalFee(), which is the
local load-scaled fee escalation, not the ledger's base fee. The panel
built on it therefore tracked this node's load state rather than the
network's cost of a reference transaction, and read as a flat line
whenever the node was unloaded.
Read it from the validated ledger's fee settings instead, alongside the
reserve values already taken from there. The observation now only
reports when a validated ledger is available, which is correct: before
that there is no network fee to report.
MetricsRegistry::start() fused three steps with different prerequisites:
the exporter/provider and the synchronous instruments need only config
strings, while the observable gauges read live Application services. The
whole pipeline therefore waited on the latest prerequisite and ran near
the end of setup() -- after beginConsensus() had already recorded the
process's only operating-mode transition. state_changes_total was
emitted into a pipeline that did not exist yet, so the series never
appeared at all.
Split the two halves. start() keeps the provider and the synchronous
instruments and now runs as soon as the registry is constructed; the new
startAsyncGauges() registers the observable callbacks and runs once
overlay_ exists, still before the first consensus round. Application
gains a matching startTelemetryGauges() so each phase has its own call
site and its own precondition.
Move the jq_trans_overflow_total observable out of initSyncInstruments()
into the gauge phase. Its callback reads getOverlay(), which asserts
overlay_ is non-null, so creating it in the early phase armed the reader
thread against a half-built application -- an assert is not caught by
the callback's catch-all. The instrument is an observable counter rather
than a gauge, which is how it was mistaken for a push-only instrument.
Both start log lines are kept, one per phase, because that timeline is
what made the original ordering bug diagnosable.
Comments and preconditions are corrected to state the rule rather than
the current arrangement: start() may only create instruments whose
values are pushed, and any observable whose callback reads a service
belongs in the gauge phase. The gauge precondition now lists the
services the callbacks actually read.
telemetry_->start() ran at the end of ApplicationImp::start(), after
overlay_->start(). Spans are emitted well before that, during setup():
beginConsensus() runs the first consensus round there. SpanGuard drops a
span whenever the global Telemetry instance is not yet live, so that
round's spans were never recorded.
Move the start into setup(), behind a new startTelemetry() seam, right
after the node identity is known. getNodeIdentity() needs only the
cmdline, the config, or the wallet DB, and initRelationalDatabase()
has already created the latter -- the adjacent peerReservations_ load
proves it is usable -- so the identity block moves up with it.
The new position is bounded on both sides: after initRelationalDatabase()
because the identity needs the wallet DB and a DB failure aborts setup(),
and before beginConsensus() because that emits the first spans.
Grafana renders `unit: "ops"` as the literal string "ops/s" and `cps`
as "counts/s", so seven rate panels on this dashboard read as
"operations per second" regardless of what they counted -- nodes added
to a SHAMap, dial attempts, ledger-data requests served.
Replace them with custom-suffix units naming the quantity, following
the `suffix:/hr` and `si:drops` precedent already in this repo. Each
noun was checked against the emitting code rather than the panel title:
sync_addnode_total counts SHAMap nodes, peer.dial spans are connect
attempts, ledger.serve spans are peer requests.
Also spell out "Ops / Sec" as "Operations / Sec" on the NodeStore panel,
since abbreviating the noun defeats the point of naming it.
Queries are unchanged; the values were already correct.
The two key-job latency panels on node-health declared milliseconds
while querying `job_running_us` / `job_queued_us`, which record
microseconds. Every reading was a thousand times too large: the p95 for
acceptLedger, 241495us, rendered as "241 sec" instead of 241ms.
job-queue.json already read the same metrics as microseconds, so the
two dashboards disagreed by 1000x on identical data.
Also replace the generic `ops`, `cps` and `cpm` units, which Grafana
renders as the literal "ops/s", "counts/s" and "counts/min", with
custom-suffix units naming what each panel counts -- jobs, ledgers,
validations, lookups. The per-minute panels already scale correctly in
their queries; only the noun was missing.
Normalise the micro sign to U+00B5 throughout. Four axis labels used
the visually identical Greek mu, U+03BC, while every unit field used
the micro sign.
Ledger Close Rate plots ledgers closed beside ledger fetches, which one
unit cannot describe; give the fetches series its own unit on a
right-hand axis. Drop two field overrides on NodeStore Read Latency
that restated the panel unit as a custom suffix -- a suffix is appended
verbatim, so it would have suppressed magnitude scaling and left large
values unreadable, the same defect fixed above.
Queries are unchanged apart from the transaction path piechart, which
moves from rate() to increase(): a per-slice "per second" reading is
not a share of a total.
Alongside, widen the Complete Ledger Ranges table to full width, hoist
the stat panels above the fold, and bring the touched panels up to the
tooltip and null-spanning guidelines.
The four job-latency panels on node-health declared milliseconds while
querying `job_running_us` / `job_queued_us`, which record microseconds
(MetricsRegistry records the raw value, and the instrument description
says microseconds). Every reading was therefore a thousand times too
large: the p95 for acceptLedger, 241495us, rendered as "241 sec"
instead of 241ms. job-queue.json already read these same metrics as
microseconds, so the two dashboards disagreed by 1000x on identical
data. Switch node-health to microseconds to match.
Also replace the generic `ops` and `cps` units, which Grafana renders
as the literal "ops/s" and "counts/s", with custom-suffix units naming
what each panel counts -- messages, fetches, calls, mismatches.
Two panels plot more than one quantity on a single axis, which no
single unit can describe. Give each series its own unit through field
overrides: reads per second beside two queue depths on NuDB Read
Pressure, and ledgers beside fetches on Ledger Close Rate, the latter
on a right-hand axis.
State Duration Rate plots a seconds-per-second time share, which can
exceed 1.0 and so is not a percentage; label it as the ratio it is.
The normalised share already exists as its own panel.
Queries are unchanged; the values were already correct.
Alongside, bring the touched panels up to the dashboard guidelines and
hoist the stat panels above the fold.
Grafana renders `unit: "ops"` as the literal string "ops/s", so every
rate panel read as "operations per second" regardless of what it
actually counted. `Ledger Build Rate` showed "0.258 ops/s" where the
value is one ledger every 3.9s -- the number was right, the unit was
meaningless.
Replace the generic units with Grafana custom-suffix units naming the
quantity, following the existing `suffix:/hr` and `si:drops` precedent
in this repo. Nine of these are `stat` panels with no axis, so the unit
string was the only text a reader ever saw.
Also switch the two trusted/untrusted piecharts and the transaction
path piechart from rate() to increase(): a per-slice "per second"
reading is not a share of a total, counts in the window are.
Queries are unchanged apart from those three; the values were already
correct.
Alongside, bring the touched panels up to the dashboard guidelines:
tooltip mode/sort/max-height, 30-minute null spanning, and axis labels
in title case. Hoist the stat panels above the fold on
ledger-operations and rpc-performance.
Panels that a later branch in this chain removes are deliberately left
alone -- fixing them would only add merge conflicts.
Telemetry must read state, never change it. Two defects here did change it,
plus three smaller correctness and privacy fixes.
doPathFind and doRipplePathFind read source_account / destination_account off
context.params to hash them into span attributes. context.params is non-const,
so those reads selected json::Value's non-const operator[], which inserts a
null for a missing key. The same object is later validated by
PathRequest::parseJson, whose first checks are isMember(source_account) and
isMember(destination_account) — so a request that omitted either field looked
present and the client received Malformed instead of Missing. Reads now go
through std::as_const, whose overload returns kNull without inserting.
PathRequest::doUpdate emitted pathfind_dest_currency as
to_string(saDstAmount_.asset()). For a non-XRP asset that renders as
"<issuer>/<currency>" with the issuer as a plaintext Base58 address, so a
plain account address reached the span pipeline even though every other
account here is hashed first. The issuer is now redacted and the currency
kept; an MPT asset renders as its issuance ID and carries no address.
PathRequestManager::updateAll created pathfind.update_all with an unscoped
SpanGuard. An unscoped guard takes the ambient span as its own parent but does
not itself become the ambient parent, so the pathfind.compute spans that
doUpdate creates never nested under it, contradicting the documented hierarchy.
It is now a scoped guard, held in std::optional because ScopedSpanGuard is
deliberately non-movable and so cannot be produced by a ternary. The skip when
there are no active subscriptions is preserved. updateAll is dispatched via
addJob and doUpdate runs synchronously, so the guard is constructed and
destroyed under the same context store, as ScopedSpanGuard requires.
The WebSocket entry point emitted the client-supplied command string directly.
That value becomes a Prometheus label, so arbitrary request input could drive
unbounded label cardinality. It is now resolved against the handler registry,
collapsing anything unrecognized to "unknown", matching what the HTTP path
already does.
Also: the pathfind.discover comment claimed future child spans could be
parented off it, which its unscoped guard cannot do — corrected to say what
would be required instead. Config-reference and task-list docs named the
parser setupTelemetry(); the API is makeTelemetrySetup().
Conflict in processSession(): this branch added the request-payload-size
attribute on the same lines where the incoming change reverted
processRequest() from bool back to void. Kept both — the payload-size
attribute stays, and the call no longer captures a return value. The
trailing status block takes the incoming side, which leaves the
rpc.http_request span's status unset.
Six related defects in the RPC/gRPC span surface, all cases where a failure
was recorded as success or an attribute was missing on an error path.
GRPCServer: the non-exception branch set the span Ok unconditionally, then
sent a possibly-failed grpc::Status. The handler can return a non-OK status
without throwing, so every failed call traced as successful. Status now
follows result.second, with the error message as the span description.
ServerHandler: eight per-item error branches appended an error reply without
recording that the request failed. Batch responses and ripplerpc < 3.0 always
carry HTTP 200, so those failures were invisible and an entirely failed batch
ended its span as successful. Added an appendItemError() helper next to the
existing httpReplyError() lambda and routed all eight sites through it, so the
flag cannot be forgotten at a new call site.
ServerHandler: the early-return validation paths set the span error but not the
rpc_status attribute. Added it to httpReplyError() so every such path gets it.
RPCHandler: the fillHandler error path set only command and rpc_status, while
callMethod sets command, version and rpc_role. Error spans were therefore not
filterable by API version or role. The error path now mirrors that set.
RPCHandler: resolveCommandSpanName() checked only that command/method were
present, not that they agreed, while fillHandler rejects a mismatch as
rpcUNKNOWN_COMMAND. A request supplying both with different values was labelled
with one of the two names, misattributing the error to a command that never
dispatched. It now mirrors fillHandler's rule and collapses to "unknown".
ServerHandler: processRequest returned bool solely so the caller could set its
span status. Telemetry should read state, not shape the signature of the code it
observes, so the signature returns to void and rpc.process sets its own status
from spanHadError. The enclosing rpc.http_request span now leaves status unset:
the OTel spec has instrumentation leave status unset unless the operation itself
errored, and reserves Ok for an operator asserting verified success.
Conflict in src/libxrpl/telemetry/SpanGuard.cpp: both sides added a different
include in the same alphabetical slot — phase-4 added <initializer_list>, the
incoming std::format change added <format>. Both are required, so both are
kept in sorted order.
SpanGuard::span() and freshRoot() joined the prefix and suffix by hand with
reserve() + three append() calls. std::format expresses the same join in one
line; libstdc++ has shipped <format> since GCC 13 and the project floor is
GCC 15.2 (BUILD.md), so it is available on every supported compiler.
Both callers are noexcept and std::format can throw (std::bad_alloc, or
std::format_error on a malformed spec), so an escaping exception would
terminate the process. The call is wrapped in a joinSpanName() helper that
catches and returns std::nullopt; the caller then returns a null guard, which
is the same degrade-to-no-op path already taken when telemetry is disabled.
Telemetry must never bring the node down.
One helper rather than a try/catch at each site keeps both call sites a single
line and puts the exception-safety requirement in one documented place.
Addresses a review comment on PR #6437.
Conflict in OpenTelemetryPlan/03-implementation-strategy.md §3.9: both
branches independently fixed the same defect (stale hand-maintained line
counts) in different ways.
- 1b (0ff947454c) stripped the Lines Added / Lines Changed columns but kept
the §3.9.1 and §3.9.2 tables.
- 1a (3ad525a48a) removed both sections outright.
Resolved in favour of 1a's deletion. The tables were pre-implementation
estimates with no source of truth, so trimming the columns only defers the
next drift; the file/component lists duplicated §3.1's directory tree, which
1b already keeps current (DiscardFlag.h, FilteringSpanProcessor). Keeping the
upstream resolution also stops the same conflict recurring on 1c..10.
1b-specific content verified intact after the merge: §3.1 retains the
DiscardFlag.h entry, the FilteringSpanProcessor and discard() annotations,
and the TracingInstrumentation removal. No references to the deleted
sections remain in any plan doc.
The §3.9.1 "Files Modified Summary" and §3.9.2 "Detailed File Impact"
tables carried hand-maintained per-component line counts that had drifted
from the plan: the Lines Added column summed to 1,565 while the Total row
claimed ~1,670. Files (34) and Lines Changed (120) reconciled, so only the
Added total was stale — residue from expanding Core Telemetry 5 -> 11 files.
Rather than patch one cell, remove both tables. They were pre-implementation
estimates with no source of truth, so any figure in them drifts again on the
next phase. §3.1's directory tree remains the canonical list of the 11 new
telemetry files, and §3.9.3-3.9.7 (risk, architectural impact, backward
compatibility, rollback) carry the assessment without inventing line counts.
No references to the removed sections exist elsewhere in the plan docs.
Resolves src/tests/libxrpl/CMakeLists.txt test_modules by keeping both
sides: develop's beast/nodestore/protocol additions (nodestore moved into
alphabetical position) and this branch's ledger module.
Someone filling in .env.grafanacloud-alloy has no reason to know that
deployment.environment and xrpl.network.type are not env vars: they are
literals inside the tier transform, because OTTL statements do not expand
sys.env(). Left alone they ship as prod/mainnet and every dashboard
environment and network filter reads the wrong tier. The example now says
so, and notes service_instance_id needs nothing here.
Alloy declared 24 spanmetrics dimensions where both collector configs
declare 28. The four missing ones -- timed_out, object_type,
validation_status and accept_gated -- are emitted by the code and queried
by ledger-sync-health panels "Ledger Serve Rate by Object Type" and
"Trusted Validation Accept Rate by Status", so on an Alloy deployment
those panels collapsed to one undifferentiated series.
deploy-run-otel-xrpld.md already requires the dimension sets to stay in
sync; the config had drifted from it. Alloy's other differences from the
collectors (no filelog, no tail_sampling) are deliberate -- it is
cloud-only by design.
Five review findings.
The validation_accept span started inside the "outcome is Current"
branch, so validation_status could only ever read "current" and the four
rejected values were unreachable. That defeated the attribute: a node
whose trusted validations are all rejected emitted no span at all, so it
looked the same as a quiet node. The span now starts before the outcome
is checked, still for trusted validations only, so a rejected one is
recorded with its real status.
The rest are consistency fixes: ValidatorSite passes the parse_error
constant instead of the literal, the 28 gauge callbacks that spelled the
`metric` label key as a literal now use label::metric like the other two,
a stray blank first line is gone from six files, and MetricsRegistry.cpp
loses a duplicate Doxygen block that documented addHistogramView but sat
above an unrelated constant.
Two gaps meant the last failure produced no evidence of its cause.
The node-log upload was gated on `if: failure()`, but the validation step
sets continue-on-error, so the job is not failing at that point and the
condition never fired. Every failed run silently skipped the one artifact
that records why a node did not reach consensus. It now keys on the
validation step's own outcome, and also collects the harness logs.
Transaction failures were logged at DEBUG, which CI does not enable, so a
run where all 3052 submissions failed on a refused connection reported
nothing about it. The first occurrence of each distinct failure kind is now
a warning and repeats stay at DEBUG, so one refused connection says so once
instead of 3052 times.
Three template variables (xrpl_work_item, xrpl_branch, xrpl_node_role)
select their datasource via ${DS_PROMETHEUS}, but the variable itself was
absent from templating.list, so those label_values() lookups resolved to
no datasource and the filters stayed empty.
Add the datasource variable as the first templating entry, matching the
other dashboards in this folder.

The lane-attribution change added acquire_ledger_deferrals and
acquire_ledger_timeouts to the gauge but left this test expecting seven
labels, so it failed on every platform of both PRs: nine emitted against
seven expected. The exporters and the counters went in as separate
commits, which is how the test escaped the update.
The two new labels are asserted with values that differ from the all-lane
totals they are a subset of, so a counter wired to the wrong lane, or one
that ignored the flag and counted every lane, lands on the totals instead
and fails.
The round built each thread's batch inside the thread, before arriving at
the latch, so a throw there left the remaining threads waiting on an
arrival that never came -- the test hung instead of failing. A spawn loop
that ended early did the same.
Batches are now built before any thread starts, so nothing between spawn
and arrival can throw, and a guard counts down the shortfall for threads
that were never spawned before joining the ones that were.
The depth accounting having moved to insert entry, depthSamples is now
the denominator of the mean depth, so it gets its own assertions: equal
to insertCount once every thread has been joined, and moving with the
duplicate-key round. The overlap assertions are unchanged.

HashRouter.h declared `class Config;` and never referred to it: the only
other mentions of the name in the file are two prose comments. Nothing
that includes this header depends on it either -- of the eighteen files
that do, the only one that names the type needs the full definition and
includes it itself. The declaration is vestigial, left behind when
setupHashRouter() moved to setup_HashRouter.h, which carries its own.
Left alone it is now an error rather than dead code. This branch's
SlotCensus work made Overlay.h include PeerfinderManager.h, because
Overlay::slotCensus() returns a SlotCensus by value. ValidatorList.cpp
includes both Overlay.h and HashRouter.h, and is the one translation unit
that reaches them without also pulling in xrpld/core/Config.h -- so
PeerFinder::Config and this declaration meet there, and
bugprone-forward-declaration-namespace reports a declaration with no
definition beside a same-named class in another namespace.
Removing it rather than including the real header: xrpl::Config lives in
xrpld, so an include would point the xrpl.libxrpl.core layer at the
layer above it.
The counters that attribute deferrals and timeouts to ledger acquisition
compared a string literal in TimeoutCounter against a separate literal in
InboundLedger. Renaming the job would have silently sent both metrics to
zero: no build error, no failing test, and documentation that quietly
became wrong. Both now use one shared constant.
Three measurement fixes landed with no doc or dashboard change, leaving text
that is now false and one fix unusable from a dashboard.
Deferrals and timeouts are recorded in TimeoutCounter, a base shared by five
subclasses, so the all-lane pair could show the documented livelock
fingerprint while ledger acquisition was healthy. The runbook procedure and
the reference doc now name acquire_ledger_deferrals and
acquire_ledger_timeouts and say why the all-lane pair misleads; a new panel
plots the ledger-scoped pair as rates on one axis, since the divergence is
the signal. The existing panel is retitled All Lanes and points at it.
Writer mean depth is depthSum over depthSamples, not over insertCount, and
the measured 1.60 came from the biased estimator, so it and the 37% queueing
share derived from it are lower bounds rather than values. The reference
table now marks them as such, and the decision rule is shown to survive the
correction rather than depending on the exact figures.
Completions were never counted for acquisitions satisfied from the local
store, so the run that read zero across 510 seconds had in fact reached
full. Every place that treated a zero as a symptom now says it only means
something on a build that has the fix.
Also corrects the sync-diagnosis label-value count from 13 to 15 and a stale
source line range; the instrument count stays 35, because both new values
multiplex onto the existing nodestore_state gauge.

getSlotCensus() had no test that called it. The existing telemetry tests
cover the gauge callback by re-implementing it against a mock meter, so
they never exercise the accessor itself and would not notice a field
added to SlotCensus without a matching census assignment.
Four tests drive a real Logic and assert every field exactly:
- a fresh Logic publishes its configured ceilings and nothing else, so
"no slots configured" is distinguishable from "configured but empty";
- inPeers with wantIncoming=false yields an inbound ceiling of 0, per the
rule in Counts::onConfig;
- one fixed and one ordinary peer walked through dial, connect, handshake
and close, asserting all seven intermediate states. This pins the
non-obvious part: Counts::adjust guards the outActive_/inActive_ branch
with !s.fixed(), so a fixed peer raises fixedActive and never
outActive. A census that conflated them would overstate slot pressure.
fixedConfigured stays at 1 after the disconnect, which is the
"configured fixed peer I cannot reach" reading an operator needs;
- bootcache and livecache depths come from separate sources, so filling
one leaves the other at 0.
Four findings from a review pass over the PR.
The "Spans & traces" row was empty. Moving the row header down to clear
the back-fill panels was only half the change -- the seven span-derived
panels stayed at their old y, one unit below the native panels, so every
pair overlapped and Grafana parented all fifteen to "Back-fill &
persistence". The panels now sit below the row header, which restores
the split the runbook already describes: eight native panels answer "how
much", seven span-derived ones answer "which". Both rows stay expanded,
so the docs no longer call them collapsed.
metric_constants() excises each namespaced block before the flat
prefix pass. The flat pass classifies by identifier prefix and is meant
for headers that name the role in the identifier because they have no
`namespace metric`/`label`/`lval`; it was running over the whole header,
so a `kLabel`-prefixed constant written inside `namespace metric` landed
in both buckets and an instrument name became a valid label key for Rule
D. Nothing in the tree does that today, which is why it went unnoticed,
and why the guard is a test rather than a fix for an observed failure.
The `site` label now keeps a non-default port and drops userinfo residue
from the host. Omitting the port unconditionally merged two local sites
that differ only by port; printing it unconditionally would have renamed
the existing `https://vl.ripple.com` series. Comparing against the
scheme default distinguishes a configured port from the one the Resource
constructor fills in. parseUrl's host group also permits '@', so a
malformed URI with two of them leaves part of the userinfo in `domain`.
Both counters are recorded in TimeoutCounter, a base shared by five
subclasses with different job limits, so they pooled every lane
together. The documented fingerprint for a stalled acquisition is
deferrals rising while timeouts stay flat -- but a saturated replay lane
reproduces that shape while ledger acquisition is healthy, and the two
counters being compared were not drawn from the same population.
Adds ledger-acquisition-scoped counts alongside the totals, discriminated
by the job name already held at both call sites, so no new state and no
signature change. The all-lane counters stay for callers that want them.
Their exporters went in with the preceding commit, which shared a file.

Depth was observed at insert entry but its sample was only counted at
insert exit, so an insert still in flight contributed nothing to the
mean while completed inserts -- disproportionately the fast, shallow
ones -- all did. The reported mean understated queueing exactly when
queueing was worst: with every writer inside its first insert the gauge
was omitted entirely, while writers-in-flight correctly showed them all.
Depth and its sample count are now both folded in at entry, so the mean
is taken over one population. Mean depth is the L in Little's Law, so a
biased L understated the derived queueing share of each insert.

Two findings from the CI clang-tidy job, both mechanical:
- MetricsRegistry.h no longer includes <ranges>. The only ranges use in
the header is std::ranges::all_of, which is declared in <algorithm>
and already included, so the include was genuinely unused.
- The computeGetObjectByHashFee() expectation table now uses designated
initializers. FeeCase has five fields, two of which are plain ints in
adjacent positions, so naming them at each row also makes a
requested/found transposition impossible to write by accident.
No behaviour change.
The workflow pinned its container image and compiler in a second place:
a hardcoded gcc-13 tag alongside the one in the build matrix. That copy
went stale when the rest of CI moved on, so this job kept building on
gcc 13 and failed on code the main CI compiled cleanly.
The tag now comes from the strategy matrix, so there is one source of
truth. The nix image carries several toolchains, so the compiler is also
selected explicitly for Conan to detect the intended one.

recordCompletion() was reached only from done(), but init() can satisfy an
acquisition entirely from the local store and return without ever calling
done(). Those completions went uncounted, so acquire_completions read zero
for a whole class of outcome. On a live clean-database sync it read 0 for
510 seconds while the node reached full, which was misread as the node
completing nothing.
Counted in init() rather than by calling done(), because done() drives the
state machine: it stores the ledger, dispatches AcqDone, updates the
fetch-rate average, and sets signaled_, which would disarm a later genuine
done(). A counter must not change behaviour. A completionCounted_ latch,
separate from signaled_, makes the count idempotent across the two
independent exits so a completion is counted exactly once however it was
reached.

BEAST_EXPECT(getFetchDurationUs() > 0) failed on the macOS arm64 runner at
DatabaseConfig_test.cpp:879. It is an assertion about the host, not the
code: Database::fetchNodeObject() truncates each fetch to whole
microseconds, and a read served from NuDB's in-memory buckets can
genuinely measure under one microsecond. On a host fast enough for every
read to truncate, the total legitimately stays at zero.
Both fetch-duration checks now compare the accumulator against the total
the scheduler's fetch reports carried, via a CountingScheduler. Each
fetch is measured once and that one value feeds both, so the equality
holds at any host speed while being strictly stronger than '> 0': a
dropped fetch, a double-count, or the write member being returned all
break it. The same reasoning is already recorded in the GTest at
src/tests/libxrpl/nodestore/Database.cpp.
The store-duration '> 0' checks are left alone: those writes reach disk
and were not what failed.
All three were rejected by clang-tidy as errors:
- readability-math-missing-parentheses on 2 * kNumStored + kNumMissing
- misc-const-correctness on the never-mutated AcquireStats 'quiet'
- bugprone-unchecked-optional-access on the read_threads_running
dereferences: branching on BEAST_EXPECT's return value hides the
has_value() check from the analyser, so the guard is now a plain if and
the macro asserts separately.
The FeeCase table used positional aggregate initialisation, which
modernize-use-designated-initializers rejects for a five-field aggregate;
the clang-tidy job failed once per row. Naming the fields also makes the
requested/found/derived/literal ordering readable at each row instead of
relying on the reader tracking four ints positionally.
The header was added alongside sanitiseHandler(), which calls
std::ranges::all_of -- but that algorithm lives in <algorithm>, which the
same commit also added and which is still needed. <ranges> itself is never
used, so misc-include-cleaner rejects it and the clang-tidy job fails on
MetricsRegistry.h:146.
Adversarial validation of the previous commit found one of its two code fixes
was diagnosed wrongly and the other incomplete. Both are corrected here, along
with the layers the first pass missed.
1. The new dial outcome was named for the wrong condition. It was added as
`duplicate` on the belief that PeerFinder had already granted a slot for the
address. It has not: `Logic::onConnected` contains exactly ONE false-returning
path and it is the self-connect check, which logs "Logic dropping as self
connect" (include/xrpl/peerfinder/detail/Logic.h). The duplicate check lives
in `newOutboundSlot`, evaluated before a ConnectAttempt exists, so a real
duplicate can never reach this branch.
That mattered beyond the name: the previous commit told operators the outcome
was benign churn to ignore, when it actually reports a local misconfiguration
-- this node has its own address in [ips_fixed] or behind its advertised
endpoint, and every dial to it is wasted. Renamed to `self_connection`,
reusing the slug `handshake_negotiation_fail_total` already publishes for the
same fault so it reads identically on both signals, and every description
corrected to say so. The fail() string now reads "Self connection" too.
The first pass also missed three enforcement and contract sites: the
ConnectAttempt.h Doxygen state machine (which still mapped the slot branch
onto tls_fail), the LedgerSpanNames unit test (which pinned exactly five
values over a std::array<..., 5> and so left the new member untested), and the
span-derived twin panel plus two reference docs that still published the old
five-value domain.
2. The credential-free site label was incomplete twice over.
- It appended the port, and `Resource::Resource` DEFAULTS that to 443/https
and 80/http when the config omits one. The label would have become
`https://vl.ripple.com:443/` where Grafana Cloud currently holds
`https://vl.ripple.com`, silently renaming the series for every deployment
already scraping this metric. Verified against live label values before and
after; the port is now omitted.
- parseUrl's path group is `(/.*)?`, greedy to end of string, so a query or
fragment lands inside `path`. A list URL authenticated by `?token=...` would
have leaked exactly as userinfo did. The path is now truncated at the first
'?' or '#'.
Also updated the MetricNames.h usage example, which still taught the raw-URI
pattern to the next author, and the 09-doc row that described the label as the
configured URI.
3. Rule J hardening from the same review: `classify_instrument_kind` returns an
`other` sentinel for a non-factory macro, and storing it in the kind set could
render a future conflict as "created as counter and other". The sentinel is
now skipped, keeping it doing what it already did -- matching no shape rule.
Added a second regression test whose input the pre-fix code reported as CLEAN
(gauge-then-histogram on a `_us` name), so the guard is proven by a 0-vs-1
difference and not only by a changed message. Both new tests were run against
a reconstructed last-wins implementation and both fail against it.
Documented the conflict class in the Rule J rows of the checker README and
CONTRIBUTING, which previously described only the suffix conventions.
Verified: naming checker exits 0 with Rule J passing all 40 real names; 140
checker tests pass; 15 dashboards validate; both workload JSON files parse;
clang-tidy over the full compile database reports no finding on any changed line
of ConnectAttempt.cpp or ValidatorSite.cpp; pre-commit passes.
Not verified: not compiled. The label change adds string truncation and the
outcome rename touches a constexpr used across three translation units, so CI's
build remains the first real check on both.

Four defects from the automated review on PR #7875, each verified against the
current tree before fixing (one further comment, the row-63 dashboard overlap,
was already fixed by an earlier commit and needed nothing).
1. Rule J could not detect an instrument-kind mismatch. instrument_kinds() wrote
`kinds[wire] = ...`, so a wire name created through two different factories
kept only the kind visited last and whichever emit site the file walk reached
last silently decided the verdict. It now collects a set per name and reports
the conflict itself -- one name exporting two instruments is the defect, and
no suffix can be correct for both. Added a regression test that builds a name
as both a counter and an observable gauge and asserts the message names both.
2. A duplicate connection was reported as `tls_fail`. The TLS handshake had in
fact succeeded; PeerFinder simply already held a slot for that address, which
is ordinary churn on a healthy node. Conflating the two made a rising
`tls_fail` unreadable -- it could mean unreachable peers or merely a busy
PeerFinder, and those need opposite responses. Added a distinct `duplicate`
outcome and carried the widened vocabulary through every place that
enumerates it: the panel description, both filter descriptions, the runbook
branch table, the runbook outcome list and the expected_spans note. The
`dial_outcome` template variable is a label_values() query, so it picks the
new value up on its own.
3. ConnectAttempt::onShutdown had no `operation_aborted` guard, unlike the five
other handlers in the same file. A clean teardown was therefore counted as
`upgrade_fail`, inflating that outcome on any node shutting down with dials in
flight.
4. ValidatorSite used the raw configured URI as a Prometheus label.
[validator_list_sites] accepts credentials in the URI and ParsedUrl keeps them
in username/password, so a configured `https://user:pass@host` would have
copied the secret into a metric label and on into the collector, Prometheus
and every dashboard. The label is now rebuilt from scheme, host, port and
path -- everything needed to tell one site apart, and nothing more.
Verified: naming checker exits 0 with Rule J still passing all 40 real
instrument names; its unit tests now number 139 and all pass; 15 dashboards
validate; both workload JSON files parse; clang-tidy over the full compile
database reports no finding on either changed .cpp; pre-commit passes.
Not verified: not compiled. Item 4 introduces string concatenation and item 2 a
new constexpr, so CI's build is the first real check on both.

Brings in the phase-10 revert of the nodestore read-latency histogram plus the
nudb_bytes -> stored_object_bytes rename.
Conflicts in MetricsRegistry.{h,cpp} resolved keeping both intents:
- MetricsRegistry.cpp: dropped everything that existed only to serve the
reverted nodestore_read_us histogram -- the addSubMillisecondHistogramView()
helper, its call site, the kSubMillisecondBoundaries array and the
NodeStoreMetricNames.h include. Kept every view this branch registers
(consensus round duration, sweep_malloc_trim_us, dns_resolve_latency_ms,
overlay_dial_latency_ms) and the shared addHistogramView() base helper.
Took the rename at the storage_detail observe() call site.
- MetricsRegistry.h: took phase-10's move of the four nodestore_state observe
helpers and their ObserveFn sink from private to public, while keeping this
branch's enriched Doxygen on observeNodeStoreTotals().
Also corrected the registered-view count in the 09 reference doc: neither side's
arithmetic survives the merge, since this branch adds four views phase-10 never
saw and the revert removes one. Ten views are registered now, not six or seven.
Drops nodestore_read_us and everything added to reach it. read_mean_us already
carries microsecond precision and separated the two sync failure modes cleanly
in live testing -- 8.8 us on a clean store against a 223 us cold-store peak --
so the distribution added no signal that changed a diagnosis.
The cost of getting it was disproportionate. NodeStoreScheduler had no path to
the metrics registry, so its production constructor grew a ServiceRegistry
parameter: a metric addition changing a production signature. That in turn
forced an edit to a pre-existing test, src/test/app/SHAMapStore_test.cpp, whose
only stake in this is that it constructs a scheduler. Worse, the scheduler is
built in Application's member initializer list, long before metricsRegistry_
exists, so the registry could not be captured once and had to be re-resolved on
every fetch -- a lookup on a path that runs millions of times per sync.
The constructor returns to taking JobQueue& alone and SHAMapStore_test.cpp
returns to the single-argument call, leaving that file differing from its
pre-change form only by the NodeStore:: to node_store:: rename it picked up from
develop.
FetchReport::elapsed stays microseconds and onFetch keeps its explicit
duration_cast to milliseconds for addLoadEvents, which takes milliseconds. That
widening was a separate fix and is what makes read latency measurable at all.
kSubMillisecondBoundaries loses its only consumer and regains [[maybe_unused]],
which is the state the commit that introduced it left it in; without the
attribute an unused constant is an error under wextra with werr.
Also removes the ledger-data-sync panel that charted the histogram and the
fetch_type and found template variables, which filtered on labels no metric
emits any more, plus the runbook and reference-doc sections and the two
instrument and view counts that named it.

The Sync State panel only ever showed Connected and Full. Two causes:
1. state_tracking{metric="state_value"} is emitted with values 0-6, where
5 is FULL+validating and 6 is FULL+proposing, but the panel declared
max: 4 with value mappings for 0-4 only. Values above 4 were pinned to
the axis ceiling and rendered unmapped. Most nodes sit at 6, so the
majority of series were clipped.
2. The gauge samples the instantaneous mode on a 10s export tick, so
states shorter than one tick fall between samples. A real sync showed
SYNCING for a single scrape and skipped TRACKING entirely. This is the
sampling hazard already noted on StateAccounting in NetworkOPs.h.
Extend the panel domain to 0-6 with Validating and Proposing mappings and
matching threshold steps, and add a colour-coded state-timeline panel where
each band's width is the time spent in that state, so brief states appear
as thin slivers rather than disappearing. The timeline reads
server_info{metric="server_state"} (raw OperatingMode 0-4) rather than
state_value, which folds 5 and 6 onto FULL and would split one Full band
into three colours.
Panel layout below the insertion point shifts down by 6 rows.
Note this makes short states legible, not lossless: exporting
StateAccounting's per-state duration accumulators is the sampling-immune
fix and is left as follow-up.

The 22 metric label values on the nodestore_state gauge were asserted
nowhere, and the depthSum assertions could not tell the real
fetch_add(depth) from a fetch_add(1) that would silently zero every
derived queueing time.
Make the four observe* helpers and their ObserveFn sink public rather
than private, so the seam the header already claimed is actually
reachable. All four are static and read only their arguments, so this
exposes no object state; a friend declaration would have granted access
to every private member instead. The assertions live in the existing
Beast nodestore suite because src/test compiles into xrpld, which
contains MetricsRegistry.cpp, while xrpl_tests deliberately does not
when telemetry is enabled.
Each helper now has its exact emitted label set asserted, so a typo in
any literal fails instead of silently producing a disjoint series, and
each derived mean is asserted ABSENT on a fresh store -- a refactor to
value_or(0) would draw a believable flat zero on a latency axis and
otherwise pass everything.
Replace the concurrent write-stats test with one that forces genuine
overlap through a latch. NuDB holds one global mutex for the whole
insert and doInsert reads the depth before entering it, so a blocked
thread records a depth of at least 2; asserting depthSum strictly
exceeds insertCount therefore cannot be satisfied by a constant 1. The
old bounds admitted that bug at their floor.
Also: cover the std::nullopt branch on the two backends that exist in
every build, bound the store-duration accumulator by the wall clock,
drop four assertions that cannot fail, and correct two comments that
claimed coverage the tests do not have -- the duplicate-key test is not
the throwing path, because nudb reports key_exists without throwing,
and no test drives NodeStoreScheduler::onFetch.
The nudb_bytes label value on the storage_detail gauge named something the
code never measured. It observes Database::getStoreSize(), which returns the
storeSz_ accumulator: the cumulative payload bytes of objects this process
handed to the NodeStore. That is not a NuDB file size. It excludes NuDB's
keys, bucket padding and log, and it resets with the process while the files
on disk do not.
The name caused two concrete errors. It invited sizing the store on disk from
a number that cannot do it, and it invited a write-amplification ratio against
node_written_bytes -- which reads the same accessor at MetricsRegistry.cpp:836,
so that ratio is a constant 1.0 and measures nothing.
The nudb_ prefix was wrong too. storeSz_ is written only by
Database::storeStats(), called from DatabaseNodeImp, DatabaseRotatingImp and
Database itself. No backend code touches it, so the value reads the same on
RocksDB. That distinguishes it from the real nudb_* family
(nudb_writers_in_flight and friends), which come from getWriteStats() and are
absent entirely on a non-NuDB backend.
stored_object_bytes says what the value is and claims nothing about the
filesystem. Docs already described the value correctly; they keep that
explanation and now also record the old name, so a query pinned to it can be
traced. Neither Backend nor Database exposes an on-disk size accessor and none
was added -- no metric reports the store's on-disk size today.
Updates the node-health panel title, description and PromQL, and the four docs
that name the label value.

Eleven local phase-10 commits, mostly documentation and dashboard-description
work, plus one real include fix. No conflicts (git merge-tree reported 0).
Reviewed for interaction with this branch:
- b50aa17aee adds <xrpl/consensus/ConsensusSpanNames.h> to RCLConsensus.cpp and
PeerImp.cpp. This is the same misc-include-cleaner finding my local clang-tidy
run reported on those two files, so the merge resolves two of the 74
pre-existing findings rather than adding any.
- 8ade2b43d9 / 7da5ac5992 / d18f713f91 rename the node-health found-ratio and
stored-bytes panels and correct the nudb_bytes and NuDB found-ratio
descriptions, then repoint the runbook at the new names. These are the same
correction phase-10 made earlier to node_reads_hit -- 'found an object', not a
cache hit -- carried through to the panels that render it.
- ledger-sync-health.json is untouched by phase-10, so none of this branch's
panel work is affected.
Verified after merging: naming checker exits 0, its 138 unit tests pass, all 15
dashboards validate, levelization produces no diff, and this branch's own work is
intact (4 touch() call sites, the ledgers_behind guard, 54 panels / 18 bargauges).
The panel was renamed from NuDB Cache Hit Ratio to NuDB Read Found Ratio,
which left the runbook naming a title that no longer exists and carrying a
paragraph saying the rename had not happened yet. Both are corrected, and
the explanation now says why the ratio is a found rate: the counter
increments whenever a fetch returned an object, and a node with
online_delete has no object cache at all.

Brings forward the node_reads_hit and nudb_bytes label corrections from phases 7
and 9.
Conflicts resolved keeping both sides:
- 06-implementation-phases.md: kept phase-10's unprefixed `storage_detail` gauge
name with phase-7's corrected getStoreSize() description.
- node-health.json: kept phase-10's rewritten panel structure and re-applied the
panel renames (NodeStore Read Found Ratio, NuDB Stored Bytes), legends and axis
labels on top of it.
node_reads_hit is a found count, not a cache hit. fetchHitCount_ increments
whenever a fetch returned an object, whatever served it, and a node with
online_delete uses DatabaseRotatingImp which has no NodeObject cache at all. The
ratio therefore reads near 100% while every fetch goes to disk, which made the
cold-read failure mode look impossible on the board.
- Phase9_taskList: node_reads_hit is a found count, not cache-served reads.
- node-health: "NodeStore Cache Hit Ratio" -> "NodeStore Read Found Ratio",
legends "Cache Hit Ratio" -> "Found Ratio" and "Reads Hit (cache)" ->
"Reads Found"; corrected the ratio panel's axis label, which read
"Operations / Sec" on a percentunit panel.
- node-health: "NuDB Storage Size" -> "NuDB Stored Bytes". nudb_bytes observes
getStoreSize(), the accumulator node_written_bytes also reads, so it is
cumulative object-payload bytes and not a filesystem measurement.
- ledger-data-sync: point the read-latency discriminator at the renamed panel.

nudb_bytes was documented as a NuDB file size, one place even claiming a
filesystem stat. It observes Database::getStoreSize(), which sums the object
payloads this process has written. It excludes NuDB's keys, bucket padding and
log, and resets with the process. node_written_bytes calls the same accessor, so
the two series are equal by construction and a write-amplification ratio built
from them is a constant 1.0. Neither Backend nor Database exposes a file-size
accessor, so nothing reports on-disk size today.
The Ledger Data & Sync panel plotting node_reads_hit / node_reads_total was
titled "NuDB Cache Hit Ratio" and described as reads served from cache.
fetchHitCount_ increments whenever a fetch returned an object, whatever served
it, so the ratio is a found rate. It reads near 100% while every fetch goes to
disk, which made the cold-read failure mode look impossible. Renamed to
"NuDB Read Found Ratio" and rewrote the guidance to pair it with read latency.

Picks up two local phase-10 commits that were not yet on the remote, the
substantive one being clang-tidy cleanup in the new nodestore metric tests.
That cleanup addresses the same two check classes my own local clang-tidy run
surfaced as pre-existing on the base branch:
- bugprone-unchecked-optional-access: ASSERT_TRUE(x.has_value()) does not teach
the analyser that the later x->/x.value() is safe, because ASSERT_TRUE expands
to a return rather than a control-flow edge it can follow. Replaced with an
explicit 'if (!x.has_value()) FAIL() << ...', which both satisfies the check
and gives a message naming what was expected.
- misc-include-cleaner: <cstddef>, <algorithm> and <optional> added where the
translation unit uses them directly.
Also AcquireStats const-correctness and a kPassThroughHandlers loop rewrite.
git merge-tree reported 0 conflicts. Both sides edit
src/tests/libxrpl/telemetry/MetricsRegistry.cpp (theirs +16/-20, ours +213/-12)
but in disjoint regions, so the union applied cleanly.
The tests added on this branch tripped six checks under
WarningsAsErrors. All of them are in test code introduced here.
bugprone-unchecked-optional-access: gtest's ASSERT_TRUE returns an
opaque AssertionResult, so the dataflow analysis cannot see that a
following deref is guarded. Replaced with an explicit
`if (!x.has_value()) FAIL()`, which the analysis does follow, or with
a direct optional comparison where no deref is needed. Both keep the
original assertion strength and add a reason string.
readability-use-anyofallof: the two consteval helpers now use
std::ranges::all_of. The static_assert still evaluates at compile
time, verified by inverting the predicate and watching it fail.
misc-const-correctness, misc-include-cleaner,
modernize-use-designated-initializers: const on a never-mutated
local, corrected include sets, and named fields on the Expected
aggregate so its two adjacent bools cannot be transposed silently.
No production code changes, and no NOLINT added.
Docs-only from phase-10: two commits refining the sync-diagnosis decision rule
and nodestore_state metric semantics.
Reviewed for conflicts with this branch's work and found none. Two points worth
noting because they touch documentation this branch also edits:
- node_reads_hit is re-described from "reads served from cache" to "fetches that
found an object (not a cache hit)". That is the accurate reading of the
counter and does not change any query here.
- The cold-read decision rule is retuned (insert mean threshold ~1.2, and the
read-mean/found-rate split for telling cold-but-held from real misses). It
does not contradict the retirement of nodestore_latency on this branch, which
removed a duplicate gauge rather than any nodestore_state series.
git merge-tree reported 0 conflicts before merging.
Two metric-level defects the sync analysis identified, fixed at the source rather
than worked around on the dashboard.
1. InboundLedgers::sweep() destroys any acquire idle for more than a minute, and
that destruction is what telemetry reports as outcome=abandoned. But
lastAction_ was only refreshed by the constructor, update() and done() --
never by the receive path. With JtLedgerData capped at 3 concurrent jobs and
33 acquires in flight, an acquire whose peers were answering normally could
wait past the cutoff for its turn to apply data and be deleted for looking
idle. Measured on a fresh mainnet sync: 490 abandoned acquires against ZERO
expired retry budgets, so every one was a sweep, not a give-up.
gotData() now calls touch(). The sweeper's idle test measures real inactivity
instead of queue wait.
lastAction_ had to become atomic to allow this. It was a plain
clock_type::time_point written by the acquiring thread and read by sweep() on
the timer thread; adding a third writer on peer threads would have been a data
race. It is now std::atomic<clock_type::duration::rep> with relaxed ordering on
both sides -- the sweeper compares against a 60-second threshold, so a value
one tick stale cannot change its decision.
2. getLedgersBehindNetwork() returned the entire ledger sequence space on a fresh
node. The existing floor only guarded being ahead of every peer; it did not
guard having validated nothing at all, so validated=0 against a live tip gave
105,892,534 -- an accurate subtraction of a meaningless quantity. It
auto-scaled every consumer's axis and would trip any threshold. Distance to
tip is undefined before the first validated ledger, so it now reports 0 until
there is one, and the sync-state signals carry the initial-acquire progress.
The clamp_max(1e6) added to the Ledgers Behind Network panel as a stopgap is
removed: the metric is correct now, and leaving the clamp would hide a real
large backlog.
Verified: clang-tidy over the full compile database reports no finding on any
changed line in the three files (the pre-existing misc-include-cleaner and
misc-const-correctness findings elsewhere in InboundLedger.cpp are untouched by
this change). pre-commit passes including clang-format and the Doxygen style
check; validate_dashboards passes.
Not verified: not compiled -- per instructions.md the build needs approval, so CI
is the first real compile of the atomic change.

Two conflicts, both additive-vs-additive; each resolution keeps both sides.
check_otel_naming.py -- phase-10 taught the L6 label extractor to match the
label MAP first and to resolve a key hoisted into a `k...Label` constant,
scanning headers as well as sources. Our side had added the two-regex
first/subsequent literal scan and the `metric_constants(root)[1]` union that
covers the `namespace label` header style.
Kept phase-10's mechanism whole: METRIC_LABEL_MAP + the `(?:^|\{)` key regex
already subsumes what METRIC_LABEL_NEXT did, since matching inside the map body
makes every pair after the first open with a single `{`. So METRIC_LABEL_NEXT is
dropped as genuinely redundant rather than kept as a duplicate scan, and the
reason it existed is folded into METRIC_LABEL's comment. Re-added our
`metric_constants(root)[1]` union on top: LABEL_CONST_DEF only matches
`k`-prefixed identifiers, so it cannot see MetricNames.h's `label::jobType`
style, and without that union Rule D would reject dashboards querying labels
Rule I forced into constants. The two derivations are complementary and both
are now documented as such.
MetricsRegistry.cpp -- both sides added a new sibling view-registration helper
next to addMicrosecondHistogramView, and both added a registration call in
initExporterAndProvider(). Kept all four helpers
(addHistogramView/Microsecond/RoundDuration/SubMillisecond) and every
registration: phase-10's addSubMillisecondHistogramView + kNodeStoreReadUs
alongside our addRoundDurationHistogramView, sweepMallocTrimUs and the two
millisecond dial/resolve ladders.
phase-10's nodestore_read_us histogram does not duplicate our work. The
nodestore_latency gauge that would have overlapped it was retired in c4e434d520
before this merge, and the surviving nodestore_state gauge is complementary
rather than duplicative: both read the same fetch measurement, but the gauge
publishes only a since-boot mean via scaledMean() and cannot yield a
percentile -- the consequence observeNodeStoreTotals' own docs state plainly --
while the histogram buckets each fetch and can. The histogram also splits by
fetch_type and found, which the gauge cannot. phase-10 registered its
explicit-bucket View, so it does not inherit the SDK default ladder.
Each file keeps its own existing naming style: phase-10's k-prefixed constants
are left as-is, ours stay namespaced.

The decision rule for "slow to reach full" keyed on an absolute read-time
threshold and a found-rate threshold that misclassified the very run they
were written to explain: a populated-store run reading 31.8 us at 88.3%
found fell through both cuts and came out as "disk-bound" rather than the
cold-read case it is.
Replace it with two ordered questions -- is the read cost several times a
warm read, and is the write path queueing -- and demote the found rate to a
splitter that only applies once reads are known to be expensive. A high
found rate on its own is the normal state of a populated store, so it can
never be a trigger. The rule now classifies all four reference datasets
correctly, and the runbook shows the rule applied to each so the "confirm
against the reference points" step agrees with the table.
Also in the runbook:
- name the source of the devnet incident figures at the point of use, and
point forward to the caveat from the same paragraph
- state the provenance of the measured columns, and split the incident
figures into their own table marked as not our measurement
- say plainly that the compounding-factor explanation is an unconfirmed
hypothesis
- correct the deferral gate: it fires at the acquisition's own job limit of
5, not at the ledgerData lane cap of 3
- note that no read-max gauge exists, so the tie-break uses max_over_time
of the mean or the read histogram's p99
- split a PromQL block that put two expressions on adjacent lines, which
parses as one invalid expression
In the data-collection reference:
- node_reads_hit counts fetches that found an object, not cache hits
- nudb_bytes is cumulative payload bytes from the same accessor as
node_written_bytes, not on-disk size, so their ratio is a constant 1.0
- write_load and nudb_writers_in_flight are the same atomic on NuDB;
document that and what write_load means on RocksDB
- correct the instrument count to 8 and the view count to 7 after
nodestore_read_us and its view were added
- scope the Phase 9 query examples to one node with the regex form

Second pass on the 54-panel audit. The first commit handled the count panels and
the description drift; these are the query and threshold defects.
Panels 4 and 6 (DNS Resolve / Outbound Dial p95) read NaN for the whole run.
Two faults compounded: both hard-coded [5m] instead of $__rate_interval, so they
ignored the dashboard time range entirely, and both wrapped the histogram buckets
in rate() even though DNS resolution and outbound dialling only happen during
startup -- a windowed rate over a series that stopped moving is 0/0. Dropping
rate() and reading the cumulative buckets gives the real distribution: p95 900 ms
for DNS, 1750 ms for dialling. Panel 52 kept its rate() (consensus rounds are
ongoing) but its hard-coded [5m] became $__rate_interval.
Panel 15 plotted 105,892,534 "ledgers behind" during the flagship window. The
underlying cause is in NetworkOPs.cpp -- getLedgersBehindNetwork() subtracts the
validated sequence from a networkTarget of 0 before any peer has reported -- and
that still needs a code fix. Meanwhile one sentinel spike flattened the real
0-20 backlog for the rest of the window, so the query now clamps at 1e6, far
above any true backlog. Reads 4 where it read 105 million.
Panel 17's sum by (from, to) dropped node identity, so with All nodes selected
every node's transitions summed into one bar. It now carries service_instance_id,
xrpl_branch and xrpl_work_item like every other panel.
Panel 38 divided by clamp_min(op_rate, 1), which turns "no operations in this
interval" into "one operation", reporting the whole duration total as if a single
op had consumed it. Replaced with a `> 0` gate so an idle interval draws a gap
instead of a fabricated latency.
Panels 13 and 45 had inverted thresholds: green began at 1 second, so every
sub-second time-to-full and time-to-first-validated rendered red -- the healthy
case was the alarming colour. Now green by default, yellow past 10 minutes, red
past 30.
Panel 48's p95 had no outcome filter, mixing abandoned and timed-out spans (which
sit at the retry ceiling by construction) into what reads as completion latency.
Restricted to outcome="complete".
Verified against Grafana Cloud: 66 queries, 0 parse errors, 56 with data, 9
legitimately empty (fault-only counters plus the write-timing series that
pre-dates both recorded nodes). The single remaining NaN is on panel 47 and is an
artifact of my verification harness forcing a hard 5m window; the panel's own
$__rate_interval returns 492 ms, so it needs no change.

A 54-panel audit across 11 dimensions, each finding adversarially re-verified
against live data, returned 38 confirmed defects. This fixes them. Most were
introduced by the recent rate-to-count conversion itself.
1. increase() was the wrong function for these counters. A counter that only
moves at startup is born at its final value inside the window and never
rises, so increase() reports 0. Measured: dns_resolve_total reads 4 but
round(increase(...[$__range])) returned 0 -- the panel lost the signal
entirely. increase() also drops whatever accrued before the window opened,
which under-reported the rest (overlay_connect_total 110 against a true 130,
unl_fetch_total 10 against 14, peer_disconnect_total 7 against 8).
All 18 count panels now use last_over_time(...[$__range]), which on a
fresh-node board is the cumulative total since the process started -- exactly
what "count" means here.
EXCEPT panel 49. span_calls_total comes from the collector's spanmetrics
connector, which is collector-side state and does NOT reset when xrpld
restarts, so last_over_time would report the collector's lifetime across every
run: it read 2624 header completions where run C actually had 297. That panel
keeps round(increase(...)) and now reports 297/278/212/7, matching the
analysis. The distinction is process-level counter vs collector-side counter,
and it decides which function is correct.
2. Descriptions still described rates after the conversion, over three passes of
wording (Reading it / Healthy range / Watch for blocks, "Rate of", "per
second", "/s", "a rising rate"). 11 panels corrected; the two surviving uses
of "rate" are legitimate (a cache hit-rate reference, and panel 49 explaining
why a count reads better than a rate).
3. Ten descriptions pointed at panel titles that no longer exist, because the
conversion renamed the panels they cross-referenced. Two others named panels
that never existed on this board at all: "Total Jobs Queued" (now Worker Pool
Capacity & Total Backlog, panel 27) and "Fetch-Pack Peer Starvation" (now
Peers Able to Serve Needed Sequence, panel 28).
4. Panels 18 and 23 applied $acquire_metric on top of a hard-coded metric
selector, so the two ANDed: any selection outside the panel's own values gave
an empty graph and All was the only usable state. The redundant template
selector is gone; the panel's metric pair is its identity.
5. Panel 23 drew two series with different ranges (received_data_depth 0-20,
in_flight 13-49) under one yellow threshold at 16, so in_flight was
permanently yellow. The threshold is now scoped to received_data_depth.
6. The "Spans & traces" row sat at y=248, the same y as panels 38/39, so Grafana
folded the Back-fill panels into the wrong row. Moved to y=296, below the last
back-fill panel. Rows are now strictly ascending with no collision.
Verified against Grafana Cloud Prometheus: all 66 panel queries parse, 0 errors,
57 returning data (up from 56 -- panel 3 was one of the ones increase() had
silenced). validate_dashboards and check_otel_naming both pass.
Not verified: no PNG renders this round; the local Grafana and Prometheus are
down, so every check ran against Cloud data via the datasource proxy.

The phase-10 merge relocated PeerFinder's Manager interface from
src/xrpld/peerfinder/ to include/xrpl/peerfinder/, and SlotCensus moved with it
so libxrpl could see it. Logic.h uses SlotCensus as the return type of
getSlotCensus() but was never given the include, so every build failed:
build/modules/xrpl.libxrpl.peerfinder/xrpl/peerfinder/detail/Logic.h:192:5:
error: unknown type name 'SlotCensus'
...:197:16: error: use of undeclared identifier 'SlotCensus'; did you mean
'getSlotCensus'?
That single missing declaration was the whole failure. The 34 further errors in
the log were cascade: PeerFinderTest could not compile, so every TEST() in
src/tests/libxrpl/peerfinder/PeerFinder.cpp failed to instantiate against
gtest-internal.h. All four platforms (ubuntu-clang, ubuntu-gcc, macos-arm64,
windows-amd64) and clang-tidy reported the same root cause.
No include cycle: PeerfinderManager.h does not include detail/Logic.h, directly
or transitively. Levelization is unchanged because both headers are already in
xrpl.libxrpl.peerfinder, so generate.py produces no diff.
This is the risk called out when the merge landed -- moving SlotCensus into the
public header was the one resolution a static check could not confirm, and only
a compile would prove it. CI is that compile, and it found this.

- JobQueue_test: drop the unused <functional>, and make the two
read-only GaugeFixture instances const. The other two stay mutable
because they submit jobs through fixture.queue.
- DatabaseConfig_test: drop the unused SystemParameters.h and include
ByteUtilities.h for megabytes(), which was reached only transitively.
Regenerate ordering.txt for the resulting edges: test.unit_test arrives
with SuiteJournal.h, and xrpl.protocol leaves with SystemParameters.h.
Rule D rejected the `handler` and `result` dashboard filters even though
both labels are emitted, because the L6 extractor missed them twice over:
- It matched only a key written as an inline literal directly after `{{`.
A label map is a braced list of braced pairs, so in
`Add(1, {{"job_type", a}, {"handler", b}})` only the first key follows
`{{` -- every later one was dropped. A key hoisted into a constant
(`{{kHandlerLabel, v}}`) was invisible in any position.
- It walked *.cpp only, so a constant declared in a header, as
kLabelResult is, could never be found.
Match the label map first and scan its pairs, resolve `k...Label`
constants through their `constexpr char k...[] = "..."` definitions, and
read headers too. Matching the map rather than any `{"key",` in the file
keeps ordinary brace initializers, such as the `{"http", "https"}` scheme
array, out of the label set -- they are not labels and must not license a
dashboard filter. Test code is skipped for the same reason Rule F skips
it: fixtures pass arbitrary literal pairs.
The new PromQL used an exact match on service_instance_id. The $node
template variable is multi-value, so an exact match returns nothing as
soon as more than one node is selected. Every one of the 442 filters
across the dashboards uses the regex form; the runbook now agrees.

A stalled ledger sync has two distinct causes that look identical from the
job queue: in both, the ledgerData lane sits at its concurrency limit of 3
with work waiting. Lane occupancy therefore discriminates nothing, and the
dashboard had no panel that separated the two.
Adds a Sync Bottleneck Discrimination row to Ledger Data & Sync with seven
panels built on the nodestore_state write-path and acquire counters:
- NodeStore Read Latency, lifetime and windowed, on a log axis with
threshold lines at 10 and 100 us. This is the discriminator: fast reads
mean the cost is on the write side, slow reads with a high hit ratio
mean every access is paying disk latency.
- NuDB Writer Queue Depth, the confirming half. NuDB takes one global
mutex per insert, so depth above 1 is queueing at that mutex.
- NuDB Insert Time, mean against true max, which quantifies how much of
each insert is wait rather than work.
- Acquire Deferrals vs Timeouts on one panel, because the livelock
fingerprint is deferrals rising while timeouts stay flat, and neither
counter shows that alone.
- Acquisition Progress and Discarded Acquire Work, the outcome side: no
completions while the lane is busy means acquisitions resolve neither
way.
- NodeStore Read Latency Distribution split by fetch_type and found, from
the nodestore_read_us histogram, since a mean cannot tell a uniformly
warm store from a mostly-warm one with a cold tail.
Every expression carries the existing service_instance_id and tier filters.
The histogram introduces two new label dimensions, so fetch_type and found
template variables are added to match.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Two different bottlenecks both present as the ledgerData job lane pinned
at its concurrency cap of 3, so lane occupancy diagnoses neither. One is
write-serialized (NuDB takes one global mutex per insert, so inserts
queue), the other is cold-read-bound on a populated store. Telling them
apart needs the storage-side signals, not the lane.
Adds to docs/telemetry-runbook.md a "Slow to reach full" procedure: a
Mermaid diagram of the two modes, a decision table keyed on whether
acquisitions are completing, the measured reference values from both
runs, and the deferral/timeout pair that fingerprints the disarmed
give-up path. States plainly that node_reads_hit is a found count rather
than a cache-hit rate, which is why a ~100% "hit rate" at 113 us per
read is the cold-read signature and not a contradiction.
Records honestly that the populated-store run was twice as fast despite
slower reads, so cold reads alone do not explain the long incident.
Adds reference rows for the 13 new nodestore_state label values and the
nodestore_read_us histogram to
OpenTelemetryPlan/09-data-collection-reference.md, in the authoritative
Phase 9 OTel SDK section alongside the existing NodeStore I/O table.

kSubMillisecondBoundaries existed but nothing used it, so per-fetch read
latency never reached Grafana -- only the coarse read_mean_us gauge did,
which cannot separate "every read took 9us" from "most took 2 and a few
took 900".
Add a nodestore_read_us histogram, register its view against the sub-
millisecond ladder rather than kMicrosecondBoundaries (whose first edge
is 100us, above the entire range a warm read occupies), and record into
it from NodeStoreScheduler::onFetch using FetchReport::elapsed, which a
previous change widened to microseconds for exactly this purpose.
The name and its labels live in a new include/xrpl/telemetry header
because the view registration (xrpld.telemetry) and the record site
(xrpld.app) sit in different levelization modules; a copy-pasted literal
would let them drift and silently drop the bucket override. Same reason
and same placement as GetObjectMetricNames.h. No new levelization edge:
xrpld.app > xrpl.telemetry already exists.
NodeStoreScheduler had no registry access, so it now takes a
ServiceRegistry and resolves the registry per call. It is constructed in
Application's initializer list, long before metricsRegistry_ is assigned
in setup() and started in startTelemetry(), so capturing a pointer at
construction would capture nullptr forever; the metric macros null-check
the registry, the meter and the instrument, so early fetches are simply
not recorded.
Labels are fetch_type and found, both already carried on the report --
4 series, fixed at compile time. A slow async read delays prefetch while
a slow sync read blocks a caller, and a miss can cost a read of every
backend, so neither dimension can be collapsed.
Negative elapsed times are skipped: the SDK rejects them and logs a
warning on every call, which on a per-fetch path is a log flood. Zero is
still recorded, since a page-cache-served read genuinely rounds to it.

nodestore_latency published six values that nodestore_state already
publishes from the same Database accessors, so the two gauges were
duplicate readings of the same atomics:
write_count -> node_writes getStoreCount()
read_count -> node_reads_total getFetchTotalCount()
write_duration_us -> node_writes_duration_us getStoreDurationUs()
read_duration_us -> node_reads_duration_us getFetchDurationUs()
write_mean_us -> write_mean_us store duration / count
read_mean_us -> read_mean_us fetch duration / count
nodestore_state is kept because its means go through scaledMean(), which
saturates at INT64_MAX instead of wrapping and omits a mean when the
denominator is zero rather than reporting a misleading 0 us.
Removes registerNodeStoreLatencyGauge, its instrument member, the
metric::nodestoreLatency constant and the lval::nodestore_latency label
namespace. The gauge-over-histogram rationale and the "p99 is not
obtainable" consequence are folded into observeNodeStoreTotals' docs.
Retargets the gauge-contract test onto nodestore_state rather than
deleting it: the scaledMean arithmetic is covered by the static_asserts
in tests/libxrpl/telemetry/MetricsRegistry.cpp, but nothing else asserts
that these named series multiplex onto one instrument keyed by `metric`.
The test now calls the production scaledMean instead of a copy of the
division, and its sub-microsecond case asserts scaledMean's actual
behaviour (a genuine mean of 0 on a zero numerator with a non-zero
count), which differs from the retired gauge's extra numerator guard.
Rewrites both ledger-sync-health copies' panel 38/39 queries and drops
the obsolete claim that the write numerator was never written: all three
concrete store paths call recordStoreDuration, so write_mean_us is live
on an ordinary node. The same stale [import_db] caveat is removed from
the runbook, the 09 reference row and the workload validator's note.
beast::Journal has no default constructor, so holding one as a plain
member deleted the suite's own default constructor and the Beast
registration macro could not instantiate it. SuiteJournal takes the
suite, converts implicitly where a journal is expected, and routes log
output into the test report.
Also removes a leftover unused local in run(), which is a hard error
under the warnings-as-errors build.

(cherry picked from commit e3c2f8279a)
The nodestore suites moved from Beast to GTest upstream, which deleted
src/test/nodestore/TestBase.h. DatabaseConfig_test stayed on Beast and
still derived its journal and batch helpers from that base, so once both
sides met in a merge it referenced three symbols that no longer existed.
It now carries its own copies, matching the current API: node object
types are NodeObjectType::Ledger rather than the old hotLEDGER spelling.

(cherry picked from commit 05d01de81a)
The phase-10 merge brought a relocation: ConsensusSpanNames.h moved from
src/xrpld/consensus/ to include/xrpl/consensus/. Three of its four consumers were
updated during conflict resolution, but this test still included the old path,
which no longer exists.
Also corrects the file header, which explained that the test is guarded on
XRPL_ENABLE_TELEMETRY "because that is the configuration in which this test target
has src/ on its include path". That reason no longer holds: the header is lib-side
now, so a libxrpl test can include it directly without reaching into src/. The
guard remains because it is what builds the telemetry test target.
Verified statically: every in-tree xrpld/ and xrpl/ include across src/ and
include/ now resolves to a file that exists (only the three generated protobuf
headers are absent, as expected before a build). check_otel_naming.py exits 0 and
its 134 unit tests pass; the one remaining reference to the old path is a
synthetic fixture path inside those tests, built in a temp dir, so it is correct
as written.
Not verified: this was not compiled. The clangd diagnostics that surfaced the
problem come from a compile database generated ~19 hours before the merge, so it
still indexes the pre-relocation layout and reports errors for headers that are
present; those specific errors are an artifact, but a real build is still the only
proof the merge compiles.

Phase-10 brought in the upstream nodestore/peerfinder/consensus reorganisation
along with its own write-path telemetry, which collided with the sync-diagnostic
signals on this branch. Twelve files conflicted; every resolution keeps both
intents rather than picking a side.
The nodestore write timing was implemented twice, independently. Both sides
added getStoreDurationUs()/getFetchDurationUs() to Database and both timed the
backend call in each concrete store(). Keeping both would have added twice to
storeDurationUs_ per store while storeStats() still counted one, so the mean
write latency would have read double on every dashboard -- silently, since no
test on either side asserts an exact microsecond figure. Resolved to one
accumulator API: recordStoreDuration(), which takes a duration, clamps a
sub-microsecond sample to zero and uses a relaxed atomic add. Phase-10's
storeDurationStats() is gone and its two call sites now use the survivor, so
all three store paths -- both store() overrides and importInternal() -- add
exactly once.
SlotCensus and its pure virtual moved from src/xrpld/peerfinder/ to
include/xrpl/peerfinder/PeerfinderManager.h, following the Manager interface
upstream relocated. The xrpld header is now phase-10's makeConfig shim, and
Overlay.h, MetricMacros.cpp and the getSlotCensus() override chain point at the
new location. ConsensusSpanNames.h and peerfinder Slot.h/Config.h include paths
followed their headers into libxrpl the same way.
InboundLedger gained phase-10's AcquireStats counters next to this branch's
span activations in both the destructor abort path and done(); neither
displaces the other. nodestore_state keeps the constant-based name this branch
requires of it and phase-10's fuller description.
Upstream #7292 deleted src/test/nodestore/Database_test.cpp, which held this
branch's testDurationAccessors. Phase-10 restored the per-store half of that
coverage in DatabaseConfig_test, but nothing covered importInternal -- it writes
through storeBatch() and never through store(), so it is a third store path that
has to time itself. That half is ported to a GTest in
src/tests/libxrpl/nodestore/Database.cpp, keeping the exact zero-before and
accumulate-after assertions and the per-instance negative check.

Two panels were left out of the previous sweep because a blanket rate-to-count
rewrite would have been wrong for them. Handled per target here.
Panel 65 (Sweep Heap-Trim) carries two cumulative counters, minor faults and
reclaimed KB. Both are count-shaped, so it becomes a bargauge over
round(increase(...[$__range])) like the rest, and the legends drop their
"/ Sec" suffix now that the values are totals rather than rates.
Panel 66 (Online-Delete Rotation) stays a timeseries. Its two targets are not
the same kind of thing: target A reads rotation_state{in_flight}, a 0/1 flag
whose whole value is seeing when it is high and for how long, and target B
rates rotation_state{copy_forward}, a cumulative write total. A count bargauge
would destroy the flag's time dimension. Instead the shared "cps" unit -- wrong
for a flag -- is replaced by per-target overrides: the flag pinned to a 0..1
left axis, the write rate on a right axis in cps. This matches how the metric
is documented to be read (MetricNames.h:648): copy_forward climbing while
in_flight is 1 is expected, climbing while it is 0 means the flag leaked.
Verified against Grafana Cloud Prometheus: 0 parse errors on both panels.

Seventeen panels on ledger-sync-health drew low-frequency discrete counters as
timeseries with an ops/s unit. The rate is arithmetically right but unreadable:
"0.1394 ops/s" is 278 abandoned tree phases over 33 minutes, and no reader can
recover the 278. rate() also extrapolates, so whole events rendered as
fractions -- peer disconnects showed 8.008 for 8 actual disconnects.
Measured every candidate against live Prometheus over a 33-minute mainnet sync
before converting; none exceeded 0.48 events/s, so all are count-shaped:
serve_refused_total 955 events 0.4785/s
ledger_quorum_shortfall_total 670 0.3354/s
sync_acquire_source_total 511 0.2559/s
overlay_connect_total 130 0.0652/s
sync_acquire_no_progress_total 109 0.0545/s
unl_fetch_total 12 0.0061/s
peer_disconnect_total 8 0.0040/s
Each becomes a bargauge over round(increase(...[$__range])) with unit short and
decimals 0, matching the existing Mode Transitions panel. Legends follow
instructions.md OTel rule 7 -- "MetricName [labels]" -- and keep node identity
via xrpl_ident, so a nine-node view no longer collapses to one bar. Panel 49
also gained node identity in its aggregation, which it was missing entirely.
Label values stay as emitted (upgrade_fail, not "Upgrade Fail"). They are wire
identifiers: rewriting them in the legend would hide what the metric reports and
break silently when a new value appears. The Title Case sits in the metric name.
The five zero-valued panels were checked rather than assumed dead --
ledger_replay_*, sweep_malloc_trim_* and rotation_copy_node_restore_total all
have real emit sites and are feature-gated off in this configuration.
Verified against Grafana Cloud Prometheus: 0 parse errors across all panel
queries, whole-number results throughout.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Three defects, all found by rendering the panels and running their queries
against a live mainnet node.
1. Ledger Acquire Phase Outcomes had an invalid PromQL escape.
The saved JSON held "ledger\\.acquire\\.(.*)", which decodes to
`ledger\.acquire\.(.*)`. In a PromQL double-quoted string `\.` is not a
legal escape, so Prometheus rejected the whole query:
parse error: unknown escape sequence U+002E '.'
The panel therefore rendered an error badge and "No data". A PromQL string
needs two characters, so the JSON must carry four backslashes.
2. The same panel never grouped by outcome, despite its title.
`sum by (span_name, timed_out, ...)` omitted `outcome`, so complete and
abandoned collapsed into one line. Measured at 16:45 UTC that hid a 29x
difference: astree complete=2085 against abandoned=71, all drawn as a
single indistinguishable series -- and every phase then showed the same
0.2596/s value, which is what made the panel look meaningless.
Now grouped by outcome, giving four real series (verified live):
header complete 0.1439/s, header abandoned 0.0772/s,
astree abandoned 0.1404/s, txtree abandoned 0.1404/s
The selector moves from timed_out (always "false" here, so it carried no
information and its filter var was redundant) to the declared
$span_outcome. Legend becomes "<phase> <outcome>"; axis label reads
"Phases / sec" to match the ops unit.
3. Seven stat panels and one heatmap dumped the raw label set as the legend.
With no fieldConfig.defaults.displayName but textMode "value_and_name",
Grafana has no name to show and falls back to printing every label:
{deployment_environment="local", exported_instance="xrpld-mainnet",
exported_job="xrpld", instance="otel-collector:8889", ...}
Rendered PNGs of panels 10 and 26 confirmed it. Fixed on ids 10, 12, 13,
14, 26, 36, 45 and 52 with the board convention already used by 24 sibling
stat panels: "${__field.labels.series} ${__field.labels.xrpl_ident}".
Verified afterwards by executing all 66 panel queries on this board against
live Prometheus: 0 parse errors, 56 returning data. The 10 empty ones are
counters a healthy node never increments plus panel 29, which is gated to stay
blank until a ledger is validated.

The Peer Ledger Supply Window panel drew supply_min_seq, supply_max_seq and
nothing else on one linear axis. Measured on a mainnet node, those sit around
105,890,000 and roughly 300,000 apart, so the 588-ledger tip movement that
shows whether sync is progressing was 0.0006% of the axis and read as a flat
line. unit "none" also printed the sequences unabbreviated and clipped the
legend.
The panel's own "Watch for" text asked the reader to compare supply_min_seq
against this node's validated sequence, but that line was not on the panel at
all, so the comparison meant switching dashboards.
Plot the two distances instead, which is what the panel was always asking
about:
History Headroom = validated_ledger_seq - supply_min_seq
Tip Gap = supply_max_seq - validated_ledger_seq
Zero is now the boundary in both directions: negative headroom is exactly the
"every peer pruned what I still need" case the description warns about, and it
becomes a zero crossing rather than a line-order comparison. Tip Gap gets the
right-hand axis because the two ranges differ by orders of magnitude
(measured: 299999..300001 against -1..1).
Both operands are gated `> 0`. Ungated, differencing the documented
"unknown window" sentinel of 0 yields the whole sequence space: measured
-105854935 for headroom and 105890295 for tip gap during the first ticks,
which destroys the axis for the rest of the window. Gated, the panel stays
blank until the node has a validated ledger and a peer has advertised a
range, which is the honest reading for that state.
Both queries verified against a live mainnet node through the full template
substitution: refId A = 300001 legend "History Headroom [xrpld-mainnet]",
refId B = -1 legend "Tip Gap [xrpld-mainnet]".
Runbook branch-C table, step 11 walkthrough and the 09 reference row follow
the rename and the new reading.

The panel built its legend with label_replace from the `from` label alone, so
every edge leaving a mode collapsed onto one series: connected->syncing and
connected->full both drew as "connected". The whole point of the from/to pair
is to tell a healthy climb from flapping, and that was exactly what the
legend hid.
label_replace cannot concatenate two labels. label_join can, which is the
pattern the consensus board already uses for its multi-label legends, so the
series now reads "from -> to".
Also regenerates the Grafana Cloud copy of the board.

beast::Journal has no default constructor, so holding one as a plain
member deleted the suite's own default constructor and the Beast
registration macro could not instantiate it. SuiteJournal takes the

Also removes a leftover unused local in run(), which is a hard error

The nodestore suites moved from Beast to GTest upstream, which deleted
src/test/nodestore/TestBase.h. DatabaseConfig_test stayed on Beast and
still derived its journal and batch helpers from that base, so once both
sides met in a merge it referenced three symbols that no longer existed.
It now carries its own copies, matching the current API: node object
types are NodeObjectType::Ledger rather than the old hotLEDGER spelling.

FetchReport::elapsed was milliseconds, so every nodestore read rounded to
zero: a warm store answers in single-digit microseconds and a cold one in
low hundreds, and both became 0 ms. That difference is the whole signal
separating a cold-read stall from a healthy node, and it was being
discarded at the type. Database::fetchNodeObject now measures once and
uses that one value for both the cumulative counter and the report, so
the two can never disagree. The job-queue call still takes milliseconds
and now casts explicitly.
BatchWriteReport::elapsed stays milliseconds and is documented as such:
a batch write covers many objects and reaches the disk, so it belongs in
that range.
Also adds a sub-millisecond histogram ladder, because the existing bucket
edges start at 100 microseconds and put the entire warm range in bucket
0. It is not wired to a view yet: no sub-millisecond instrument exists to
name, so the edges wait for the instrument that records read latency.
The new test captures what the nodestore reports and asserts the reported
total equals the internal microsecond accumulator exactly, plus that at
least one report is not a whole number of milliseconds -- which a
millisecond-typed field can never satisfy on any hardware.
Both files use telemetry::consensus::span::* but reached the declarations
only transitively, which misc-include-cleaner rejects. Add the direct
include now that the header lives under xrpl/consensus/.
The nodestore namespace became xrpl::node_store when develop was merged
in, but one mock override still named the old spelling, so it did not
match the ServiceRegistry signature it overrides. The sibling mock in
TestServiceRegistry.h was already correct.

Adds the derived read and write means, the NuDB writer depth and insert
timings, and the seven acquisition counters to the existing
nodestore_state gauge. Every value multiplexes onto that one instrument
through its `metric` label, so no new instrument is created.
Means are omitted rather than reported as zero when their denominator is
zero, so a dashboard shows a gap instead of a plausible wrong number. All
four go through one new scaledMean() helper so the guard cannot be
forgotten at a future call site; it also saturates instead of wrapping,
because a wrapped gauge reads as a healthy-looking dip. A zero total over
real samples still reports zero, since a store fast enough to truncate
every sample must not look dead.
The NuDB write-path block is skipped entirely when getWriteStats() is
nullopt, which is every backend but NuDB, so absent labels distinguish
"not measured" from "measured, and idle". Writer depth is scaled by 100
and named accordingly, because it sits just above 1.0 and an integral
gauge would truncate the whole signal away.
The gauge callback body is split into four static helpers to stay inside
the per-function line budget and to make each domain testable with a
recording sink.
Also corrects nudb_bytes, which called getStoreSize() exactly as
node_written_bytes does, so the obvious write-amplification ratio was a
constant 1.0 and the old "on-disk size" comment was wrong. No file-size
accessor exists on Backend or Database, so the value is unchanged and the
comment now states what it really is.

clang-tidy had been skipped on this branch while CMake configure was
failing, so these findings in makeStageSpan surfaced only now:
- brace the three single-statement if bodies (readability-braces-around-statements)
- compare the pointer parameter explicitly against nullptr
(readability-implicit-bool-conversion)
- include xrpl/protocol/Protocol.h for LedgerIndex (misc-include-cleaner)
A saturated ledgerData lane makes TimeoutCounter re-arm its timer
without running the timer body, so timeouts_ never advances and the
six-timeout give-up can never fire. Acquisitions then neither finish
nor fail until the one-minute sweep destroys their partial maps, and
the work restarts. Every step of that chain was debug-log-only, so a
node at warning level could not be diagnosed after the fact.
The counters are separate on purpose: deferrals rising while timeouts
stay flat is the signature, and no single counter shows it.
Completions are recorded in done() rather than at the "Done: complete"
log line, because that line also fires for failures and misses the
checkLocal and receiveNode paths; done() is the one funnel every
outcome passes through and its signaled_ guard makes it idempotent.
AcquireStats is only forward-declared in ServiceRegistry so libxrpl
still includes nothing from xrpld. The src/ include path for the test
binary moves out of the telemetry guard, since a header-only type
under src/xrpld/ is testable in every build.

The consensus headers moved into the isolated xrpl/consensus module and
took a dependency on xrpl/telemetry for the tracing span constants, but
two things were left behind:
- Four includes still pointed at the old src/xrpld/consensus/ location,
which no longer exists, so the build failed with
"fatal error: 'xrpld/consensus/ConsensusParms.h' file not found".
- xrpl.libxrpl.consensus never linked xrpl.libxrpl.telemetry. add_module
isolates each module's headers, so xrpl/telemetry/SpanNames.h was not
on the include path even once the include was repointed.
Repoint the stale includes at xrpl/consensus/, and declare the telemetry
module before consensus so consensus can link it. Regenerate ordering.txt
for the resulting edge.
NuDB serializes every insert behind one global mutex held for the whole
call, so a caller cannot see how long it waited. Record instead the
writer depth joined at and the wall time spent; with mean depth L and
mean insert time W, Little's Law gives service time W/L and queueing
W - W/L. That distinguishes a serialized write path from a saturated
disk: measured on a dev box the device sat 89 percent idle while
throughput stayed flat at 42k inserts per second.
The accounting runs from a ScopeExit guard because the insert can
allocate and therefore throw; leaking the depth would strand the gauge
above zero for the life of the process.
getWriteLoad also stops returning a hardcoded zero. It now reports
writer depth, which is bounded by the writing-thread count and so stays
far below the kMaxWriteLoadAcquire cutoff that gates history
acquisition, where returning bytes or microseconds would have silently
suppressed it.

The phase-2 merge re-added the pre-telemetry `add_module(xrpl tx)` block
without removing it, leaving the module declared twice. CMake's
add_library rejects a repeated target name, so configure failed before
any compilation:
add_library cannot create target "xrpl.libxrpl.tx" because another
target with the same name already exists.
Drop the stale pre-telemetry block and keep the one that follows
add_module(xrpl telemetry), which links both ledger and telemetry.
libxrpl/tx needs the telemetry link for the tx.transactor span, and
levelization already records `libxrpl.tx > xrpl.telemetry`.

The isValidJson2 call site in RPCCall.cpp already forces instantiation
of std::all_of over json::ValueConstIterator, so a regression that
removed the iterator traits would fail the real build. A dedicated
static_assert test is redundant; remove it.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
json::ValueConstIterator and ValueIterator declared difference_type,
reference and pointer but not value_type or iterator_category. Under
C++23, std::iterator_traits then classifies them as output iterators,
so std::all_of over a Value's members (isValidJson2 in RPCCall.cpp)
fails to instantiate on GCC 13/14 with:
cannot convert 'output_iterator_tag' to 'std::input_iterator_tag'
GCC 15 masks this via LWG-3798/P2609, but the perf CI image ships
GCC 13, so the source needs the traits regardless. The iterators wrap
a std::map iterator (++/-- only), so the category is bidirectional.
Add value_type + iterator_category to both iterators, include <iterator>,
and add a regression test asserting the traits and that std::all_of /
std::count_if compile and run over Value members.

The gcc debug-coverage job rejected an unbraced `if` whose body is a GTest
assertion: EXPECT_EQ expands to an if/else, so the outer `if` leaves an else
that could bind either way, and -Werror=dangling-else refuses it. clang does
not warn, which is why only that one job failed.
Braced the span-names case that failed, then swept every test file this
branch touches for the same shape and braced the two others found, so the
next gcc run does not fail on the next one down the list.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The gcc debug-coverage job failed where clang, macos and windows passed:
gcc's -Werror=type-limits rejects comparing an unsigned expression against
zero with >=, because it is always true.
The assertion was vacuous anyway. Both operands are unsigned, so the check
proved nothing, while the comment beside it says the intent was a non-zero
microsecond figure. Now asserts strictly positive, which is what it meant.
The same job also logs a CMake LTO capability probe failing on a missing
compiler-ar and prints the code-generation guard's echo line; neither is
related to this branch.

All eleven were reproduced locally against the same checks before fixing.
Six unused includes, left behind when the merge unioned two sets of includes
and later edits removed their only users: algorithm, functional, numeric and
thread in the job-queue test, and cstdint in the sync-state test and the load
manager. Each verified unused by grepping for every symbol the header
provides, so none is a still-needed include being dropped.
The telemetry registry header included ranges for a std::ranges::all_of call,
but that algorithm comes from algorithm, which the header already included.
Two consteval handler-name loops became std::ranges::all_of, which reads as
the predicate it is, and the two flagged fixtures are const.
Also picks up the levelization baseline the check asked for: the consensus
span-name test adds one edge from the libxrpl tests to xrpld.consensus, which
is the exact line CI's diff requested.

Two suspects from the 3.3.0 slowdown investigation had no signal. Both were
already computing the numbers and throwing them away, so this exposes them
rather than adding measurement.
Per-sweep heap trim. The trim runs after every cache sweep, and its cost
scales with resident heap, so it is the leading explanation for a node with
a populated database syncing slower than a fresh one. The report already
carried duration, fault deltas and reclaimed pages, but the whole
measurement sat behind a debug-journal check, so an ordinary node measured
nothing, and the call site discarded the result. The measurement now always
runs and only the log line stays gated. Records trim duration, minor faults
and reclaimed kilobytes. Measured cost of the always-on path is about six
microseconds per sweep against a trim costing milliseconds, at a cadence of
ten to a hundred and twenty seconds.
Honest limit, stated in the runbook: the fault delta spans only the trim
call, so it shows the trim itself faulting but not the faults that follow as
caches refill. The duration is the signal to correlate against sweep-job
queueing.
Rotation writes. Rotation copies archive-served reads forward and re-stores
nodes missing from both backends, both of which compete with sync I/O and
only happen on a populated online_delete database. The copy-forward count
existed but was reset by the rotation's own log line, so a metric reading it
would drop to zero on every swap; a never-reset total sits beside it now.
The re-store count was not measured at all. Rotation duration is
deliberately not recorded: the health throttle sleeps at eight points inside
the sequence and dominates exactly when the node is unhealthy, so the number
would conflate work with waiting.
Nothing added for the other two suspects. Get-object serving is already
covered by the handler label, the lookup histogram and the deferred and
saturation gauges; peer churn by the disconnect-reason counter.
Also replaces nine per-file cspell ignores with one ignoreRegExpList entry
for the telemetry macro names, and picks up the levelization baseline for the
consensus span-name test.

fetchDurationUs_ had no getter, so telemetry reached it by building a JSON
object, stringifying a uint64 and parsing it back with stoll on every
collect tick. storeDurationUs_ was declared and never written or read at
all, along with the jss::node_writes_duration_us key.
Both now have accessors, both production store paths time their backend
call, and the registry reads them without the round trip. get_counts also
reports the write duration, so the RPC and the metric agree. Mean read
latency is the signal that separates a cold store from a warm one: warm
reads are single-digit microseconds, cold ones low hundreds.

Both were uint32_t while every sibling counter was uint64_t. On a
multi-day node node_read_bytes read 1,481,244,491 for 1,894,924,394
reads, i.e. 0.8 bytes per read, which is impossible: the counter had
wrapped about 350 times. Read hit rate is used to tell a cold-read
stall from a write-lock ceiling, so a wrapping numerator makes that
diagnosis wrong rather than merely imprecise.
getFetchTotalCount() was already backed by a uint64_t member, so its
32-bit return type truncated a correct value at the accessor. All
three getters now return uint64_t.

Found by reviewing what each metric actually measures, with attention to the
derived and bucketed ones. All five could report healthy while the node was
not, or the reverse.
- The nodestore latency panel took rate() of a mean. The gauge already
divides duration by count in code, so rating it produced a figure with no
unit, and Prometheus discards a gauge's decreases, so a heavy back-fill
read as roughly zero microseconds per operation. The cumulative duration
totals are now exported alongside the means, and the panel divides the
rate of the total by the rate of the count, which is the latency over the
panel's own window rather than a since-boot average that flattens with
uptime.
- The DNS-resolve and outbound-dial histograms had no explicit buckets, so
they inherited a ladder that stops at ten seconds while the dial timer is
fifteen. Every timed-out dial fell in the overflow bucket and p95 read
exactly ten seconds however bad it got. Both now have a ladder reaching
thirty seconds with fifteen on its own boundary, so a timeout is
distinguishable from merely slow.
- The missing-node counts only cleared when a tree completed, so a
timed-out or failed acquire left its last count latched. Since the gauge
reports the maximum across everything still in the collection, and
eviction waits on a grace period plus the sweep interval, a finished node
reported as stuck for minutes. That inverts the one signal that separates
stuck from slow. Cleared unconditionally on the terminal path instead.
- A disabled quorum published a sentinel so large that, on a timeseries
axis shared with the trusted-key count, it flattened the key line to the
baseline and hid the outage it was meant to mark. The series is now
omitted and a quorum_disabled flag carries the state.
- Two panel descriptions claimed a one-second export cycle. The reader is
configured for ten.

The write-duration test encoded the behaviour from before the store path was
timed. It populated the source database through store(), then asserted that
database's write duration was still zero, which was only true while
importDatabase was the sole timed path. Both concrete store overrides now
time their backend write, so an ordinary store run accumulates a duration
and the assertion failed.
Turned that stale assertion into a positive one: an ordinary storeBatch must
produce a non-zero duration, which is the case a real node actually
exercises. The negative half of the test, proving the accumulation is
per-database rather than a shared global, now checks that the import leaves
the source's store COUNT unchanged, since the source's duration is
legitimately non-zero from its own writes.
80552 tests across the six affected suites pass.

These are the first failures found by actually building and running the new
telemetry tests. All three were defects in the tests, not the metrics.
- state_changes_total expected six series from seven transitions, but two
edges were traversed twice, so there are five distinct from/to pairs. The
repeat is the point of the label: flapping raises the count on one edge
rather than minting a new series, so the assertion now says five and
explains why.
- shamap_cache_hit_rate compared for exact double equality against a value
that reaches the gauge through a float hit rate, so 0.9 arrives as
0.89999997. Now compares within a tolerance far tighter than any
threshold a dashboard reads, since asserting exact equality was only
asserting the float representation.
- nodestore_latency shared one provider across four scenarios. The reader
reports cumulative temporality, so a mean observed by an earlier scenario
was still present in the next collection, which defeated the two
assertions that a mean is absent when its denominator is zero. Each
scenario now collects from its own provider.
139 of 139 telemetry tests pass.

Phase-10 independently instrumented the peer object-fetch path while this
branch instrumented fresh-node sync, so the two overlapped in three places.
Resolved by keeping each side's stronger implementation rather than shipping
both.
Per-job-type waiting/running/deferred existed twice. Phase-10's version
survives: it publishes per-type gauges from JobQueue::collect(), which
snapshots under the queue lock and publishes after releasing it, a
deliberate lock-order fix against the collector's own lock. This branch's
jobq_backlog gauge and the JobQueue::getJobTypeCounts() accessor that fed it
are removed, along with their panels, assertions and reference rows.
jobq_saturation stays: it reports the whole worker pool, which phase-10 has
no equivalent for.
The histogram view helper also existed twice with identical bodies under two
names; one survives, and the microsecond ladder is now the named array
rather than boundaries repeated inline. The job_type label was declared
twice, once as a file-local constant invisible to the naming check; both it
and handler now come from the constants header.
Two things phase-10 adds are complementary, not duplicates, and are kept as
they are: the handler label, which separates the two request kinds that both
report as the same job type, and getobject_rejected_total, which counts
malformed requests where this branch's serve_refused_total counts requests
this node declined to serve.
Also fixes two naming-check failures that pre-date this merge on phase-10.
The check derived label keys only from namespaced constants, so it could not
see the per-subsystem headers' flat k-prefixed style and rejected dashboards
querying labels the code really emits. It now reads both styles, with the
enforcement rules unchanged.

Metric names and label keys were bare string literals, repeated across the
emit site, the gauge registration, the unit test, the workload manifest, the
dashboard queries and the reference table. A rename touched six places and a
typo in any one of them failed silently: a metric that never appears, or a
label that never joins.
The span side already had this right, with names and attribute keys declared
once in the *SpanNames.h headers and a CI rule rejecting literals at call
sites. That rule only ever covered spans, so the metric side had no
equivalent and no suffix convention was enforced by anything.
- Adds MetricNames.h declaring every instrument name, label key and bounded
label value this story emits, grouped by subsystem, following the existing
span-name header layout.
- Converts the call sites subsystem by subsystem. The emitted strings are
unchanged: 75 names before, the same 75 after, verified by extracting the
wire strings from both trees and diffing the sets.
- Extends the naming check with three rules: no literal instrument name or
label key at an emit site, the duration and counter suffix conventions,
and every name in the workload manifest resolving to a constant. The
first rule is ratcheted per metric family so the pre-existing families
warn rather than block, keeping the remaining work visible instead of
forcing one unreviewable change.
Constants are character arrays rather than the span headers' StaticStr,
because the metrics API takes a string view that will not construct from it.
Two things the conversion exposed: a serve-refusal reason that the original
inventory missed because it is passed through a ternary, and a label whose
constant made it invisible to the checker's literal scan, which would have
failed a dashboard rule.

The board and runbook had grown by append across eight work packages, so
they read in the order the work was done rather than the order a node
progresses. This is the coherence pass; it adds no new instrumentation.
- Dashboard: 52 panels regrouped from two rows into nine that follow the
fresh-start sequence — bootstrap, peer supply, sync state, acquire and
SHAMap fetch, job queue, quorum and publish, terminal blockers, then
back-fill and spans collapsed since they answer conditional questions.
Layout only: no title, query or description changed.
- Runbook: the flat step list becomes a decision tree branching on the
observed symptom, with the amendment-block check first because it is
terminal. Each branch names the panels, what healthy and unhealthy look
like, and what to conclude. The existing steps are kept as the detail
bodies.
- Reference table: every signal name re-checked against the code and every
named panel against the board; four stale panel references fixed.
- Validation: every signal is now either asserted or covered by a note
explaining why a five-node local cluster cannot produce it.
Also fixes the write-latency signal, which was inert on a real node: the
store duration was only recorded on the database-import path, while the two
production store implementations did not time themselves, so an ordinary
node reported a write count with no latency. Both now time the backend
write, which is the disk work this signal exists to expose. Without it the
"existing database syncs slower than a fresh one" diagnosis had no primary
signal.

Completes the join left open when the acquire and consensus work landed in
parallel. The acquire span now derives its trace id from the ledger hash it
already records, so a fetch shares one trace with that ledger's validation,
acceptance and store, and its three phase children inherit the same id.
Reading one trace now answers the whole question for a slow ledger: whether
the data was slow to arrive, slow to be accepted, or slow to persist.
The acquire span stays an optional member of the join group, for the reason
its own entry already gives: a healthy cluster agreeing from genesis rarely
back-fills, so the span need not appear on every run.

A slow fresh-sync ledger produced spans scattered across threads with no
way to relate them. They now share a trace id derived from the ledger's own
hash, the one value every participating site already holds, so nothing new
is plumbed across threads. This is the pattern the transaction pipeline
already uses for its tx id.
Joined: ledger.validate, ledger.store, and a new
consensus.validation.accept recorded when a trusted validation arrives. In
Tempo, searching one ledger hash returns them together, so an operator can
tell whether the ledger was slow to arrive, slow to be accepted, or slow to
be stored. They are siblings rather than a chain because the accept gate is
entered from three different threads, so no fixed parent order exists.
consensus.validation.accept also records why an arriving validation did or
did not advance the gate, which makes "validations arrive but are all
rejected" visible for the first time.
consensus_round_duration_ms turns the existing round-time span attribute
into a histogram, so a fleet trend needs a metric query rather than raw
trace inspection. An explicit bucket view is required, not optional: the
SDK default tops out at ten seconds while consensus abandons a round at two
minutes, so slow rounds would all fall in one bucket and every quantile
would read exactly ten seconds. Cost is one record per round.
Record layer: the histogram is native and needs no collector change. The
two new bounded attributes are added as span-metric dimensions to both
collector configs. The ledger hash stays out of them, since a per-ledger
dimension mints a series per ledger; it is indexed in Tempo as the join key.
The ledger.acquire span is not joined yet, because that file was being
changed concurrently. It is registered as an optional member of the join
group so nothing fails, and switching it is a one-line follow-up.

Four blind spots in the sync exchange, each now a span:
- txset.acquire: transaction-set acquisition had no span at all, though it
is the sibling of ledger.acquire and runs every consensus round. A round
that falls behind because its tx set never arrived was indistinguishable
from one that deliberated slowly.
- ledger.acquire.{header,astree,txtree}: the acquire span was flat, so the
account-state tree, which dominates a fresh sync, could not be separated
from the transaction tree. These are children, closed before the parent.
- peer.dial: the outbound dial already had outcome counters; the span adds
the per-attempt timeline, so a slow stage is visible rather than only its
terminal reason.
- ledger.serve: serving a peer's ledger request was uninstrumented, so this
node's contribution to someone else's sync was invisible.
Every span finalizes exactly once. Outcomes come from shared compile-time
rules rather than a literal per branch, so no exit can mislabel itself and
an exit added later cannot omit one. Destructor paths are noexcept.
One rule needed care: the timeout path also sets the failure flag, because
that is how the timeout loop stops, so precedence puts timeout ahead of
failure or a timed-out acquire would read as a data fault.

The quorum and publish gauges were emitted but never surfaced: no panel, no
harness assertion, no reference entry. Completes those layers.
- Four panels: trusted validations against the quorum target on one axis so
a tally climbing toward quorum is visually distinct from one flat below
it; publish lag; pre-accept shortfall rate; and time to first validated
ledger.
- Both signals are asserted by the workload validator. The shortfall
counter does fire on a healthy cluster, because this node validates and
then immediately re-enters the accept gate before its peers' validations
arrive, so the first evaluation of every round tallies short. The panel
and note say so, and give the fault signature instead: the shortfall rate
outpacing the ledger-close rate while the tally stays flat and nothing
ever reaches first-validated.
- The quorum target is deliberately drawn as its own line rather than as a
headroom stat, so the disabled-quorum sentinel reads as an unreachable
target instead of an unreadable negative number.
Also removes three reference rows that were appended twice when two agents
each documented the same back-fill signals.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Registers the new gauges, renders them, asserts them and documents them, so
each signal reaches an operator rather than stopping at the emit site:
- MetricsRegistry: gauge registration for ledger_quorum_publish,
nodestore_latency, peer_ledger_supply, peerfinder_slot_census and
amendment_block, each guarded by the detached-callbacks check and
tolerant of services that are not ready yet.
- Ledger Sync Health dashboard: panels for the new signals, filtered by
the node template variable like every other board.
- Workload validation: the new series are asserted, so a signal that
regresses to absent fails CI. Signals the local cluster structurally
cannot produce, such as a replay fallback or an amendment block, are
noted rather than asserted, which would fail red on a healthy run.
- Reference, runbook and glossary entries, including the diagnosis order
for a node that has peers and validators but never validates.
- Regenerated levelization baseline: three new one-way edges from the
telemetry and test modules, no new cycles.
Also drops an unused cstddef include from the macro tests, which the
include checker rejects.

The span only recorded an outcome on the normal completion path. An
acquire that stalled and was later swept ended with no outcome at all, and
its duration stretched to the sweep interval rather than the real fetch
time. So the one case these signals exist to catch, a fetch that never
finishes, was the one case that could not be traced, and aggregate outcome
and timeout rates read low exactly when nodes are stuck.
- Adds an abandoned outcome value for the swept-while-fetching case.
- Routes every exit through one idempotent finalizer, so a span is
finalized exactly once whether it completes, fails, short-circuits on
local data, or is destroyed mid-fetch. The destructor path cannot throw.
- Adds the ledger hash to the span and backfills the sequence once known,
since by-hash acquires start without one and could not otherwise be tied
to a specific ledger.
- Record layer: outcome stays a span-metrics dimension in both collector
configs, which drift apart if only one is edited. The ledger hash is
indexed in Tempo for trace search instead, because a per-ledger value as
a metric dimension would mint a new series every ledger.

Quorum and publish (A5):
- ledger_quorum_publish gauge: the trusted-validation tally against the
quorum the candidate ledger must reach, plus the gap between the
validated and published sequences. The published sequence was never
exported, so a publish pipeline falling behind healthy validation was
invisible.
- ledger_quorum_shortfall_total: counts the pre-accept early return where
a node has peers and validators yet still declines to declare a ledger
validated. That path was log-only, and it is the difference between
accumulating toward quorum and never reaching it.
Back-fill and persistence (A6):
- nodestore_latency: read and write service time. storeDurationUs_ was
declared but never written and had no accessor, so there was no write
latency signal at all. This is the direct fingerprint of a node with an
existing database syncing slower than a fresh one, where the node cache
is cold and every tree step reaches disk. Distinct from the existing
NuDB read panels, which show volume and hit ratio rather than service
time.
- ledger_replay_fallback_total and ledger_replay_outcome_total: the replay
path silently falls back to plain acquisition on timeout or failure, so
a defeated optimisation looked like ordinary slow back-fill.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Whether the network can even serve this node, and whether the node is
about to be shut out of validation, were both invisible:
- peer_ledger_supply: how many connected peers advertise a range covering
the sequence being fetched. Peers each track a range from status
changes, but nothing aggregated them, so "nobody has what I need" looked
identical to "peers are slow".
- peerfinder_slot_census: outbound active against capacity, connection
attempts, inbound, fixed configured against active, and the bootcache
and livecache sizes. All were computed already; only two were exported,
read at unrelated instants, so they could not be compared.
- peer_disconnect_total{reason,direction} and peer_accept_total{outcome}:
every disconnect previously collapsed into one number, so our own
backpressure could not be told from topology or network faults. Reasons
are a fixed set of literals recorded on the peer and emitted once at
close, never data supplied by the remote end.
- serve_refused_total{request,reason}: the other half of the sync
exchange, when this node declines to serve a peer.
- amendment_block: whether an unsupported amendment is expected and how
long until it activates. Amendment-blocked is terminal for validation,
so the countdown is the only leading indicator. The amendment id is
deliberately not a label, since the network can vote an id this build
has never heard of; it is already logged.
- ledger_jump_total: repeated last-closed-ledger switches, which mean the
node is thrashing between chains.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Sync-critical job types run at very low concurrency limits (ledgerRequest
and ledgerData allow 3 each), so a node can stall simply because those
jobs are held back behind other work. Nothing exposed that until now:
the existing job metrics are rates and quantiles of jobs that already
moved, or a single queue-wide depth.
- jobq_backlog{metric,job_type}: instantaneous waiting, running and
deferred counts per job type. Deferred is the starvation signal and had
no exposure anywhere; it is set when a type is at its concurrency limit.
- jobq_saturation{metric}: running tasks, worker-thread count and total
waiting, so a slowdown spanning several subsystems can be attributed to
worker-pool exhaustion instead of being diagnosed once per victim.
Both read through two new const accessors on JobQueue that take the
existing mutex once and copy integers, so a single reading is internally
consistent and no per-job cost is added. The job_type label reuses the
same JobTypes name helper the existing job counters use, so the two label
sets join.

Post-deploy verification against Grafana Cloud found two problems on the
job-queue dashboard.
Every aggregating panel's displayName names four labels, but the queries
aggregate with `sum by (...)` lists that omit `xrpl_work_item`, so that
part of the legend rendered as an unresolved reference. Pre-existing, but
splitting the wait and execution panels by job type made the legend
load-bearing, so it is fixed here: `xrpl_work_item` is added to the ten
affected sum-by lists.
The two panels split by job type in the previous commit also kept their
seven-section descriptions. They now carry the same ten sections as the
rest, and their glossary links point at the real `job-queue-job-type`
anchor rather than a `job-queue` anchor that does not exist.
Verified no dashboard links a glossary anchor that is absent.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The eight panels added for the GetObject and job-queue metrics did not
follow the conventions the rest of the dashboards use.
- Descriptions go from seven sections to the ten used by the other 159
panels, adding Keywords, Computation boundary and References. The
existing diagnostic guidance is kept; only the format changed.
- Six glossary entries added for the terms those References link to
(concurrency limit, deferred job, handler label, NodeStore lookup
hit/miss, resource charge), so no link is dead.
- displayName becomes `${series} ${xrpl_ident}`, the form 122 of 143
panels use. This needs the label_join wrapper that builds xrpl_ident,
which these queries lacked, so it is added to ten targets; without it
the legend would render an unresolved label.
- Legend blocks now match each dashboard's own convention rather than
being split three-with and four-without across the new panels.
Job Queue Wait Time and Job Execution Time dropped job_type from their
aggregation, so every queue collapsed into one line and the legend could
not say which queue was slow. Both now split by type, capped with topk
to stay readable, matching the per-type panel already on that dashboard.

Resolved five files. In each case both sides had content worth keeping,
so nothing was taken wholesale:
- MetricsRegistry.cpp: kept the incoming `handler` label on the job
instruments and re-applied this branch's `queuedDurUs >= 0` guard,
which the incoming side does not have.
- telemetry-runbook.md: took the incoming gauge table, which adds the
three per-job-type rows, and re-applied this branch's corrected
`jobq_job_count` name.
- 09-data-collection-reference.md: kept this branch's validation
inventory (newer counts, extra Config File column) and inserted the
incoming call-site and per-job-type gauge rows plus their explanation.
- node-health.json: merged structurally rather than by text. This
branch's panels are authoritative; only the two incoming job-queue
panels were appended, below the existing layout. The
`Validated Ledger Seq` panels added directly in Grafana are preserved.
- job-queue.json, ledger-data-sync.json: panel sets were identical, so
took the incoming side for its `$handler` variable, the handler filter
on existing queries, and the new panels. Verified no panel was lost.

Resolved OpenTelemetryPlan/09-data-collection-reference.md: both sides
document the same new metrics, reached by different routes. The incoming
sections came from the phase-6 edit merged forward; this branch already
documents the same surface in its own layout, with the job lifecycle
metrics and the GetObject request path under the MetricsRegistry
section rather than a separate 2a.
Kept this branch's sections to avoid duplicate entries for every metric.

Resolved OpenTelemetryPlan/09-data-collection-reference.md: this branch
replaced the StatsD-shaped Section 2 with OTel-native naming, so the
incoming StatsD tables and the StatsD per-job timer section do not apply
here. Kept this branch's names throughout.
The incoming per-job-type saturation gauge section is new content and is
retained, renumbered to 2.5 and rewritten for the OTel naming: bare
lowercase `jobq_<jobtype>_{waiting,running,deferred}` derived through
OTelCollector rather than the case-preserving `xrpld_`-prefixed StatsD
form.

Slowness on the peer object-fetch path could be observed but not
attributed. Job duration metrics carry only `job_type`, and both
`RcvGetLedger` and `RcvGetObjByHash` report as `ledgerRequest`, so a
queue-wait spike could not be traced to a handler. Nothing measured
NodeStore cost, request size, or the differential charge.
Latency now decomposes into three additive parts, each separately
measurable:
end-to-end = queue wait + NodeStore lookup + everything else
- `handler` label on job_queued_total/_started_total/_finished_total and
job_queued_us/job_running_us. The value is sanitised: a name passes
through only if non-empty and all ASCII letters, else "other". Two job
names embed a ledger sequence, so a raw label would mint one series
per ledger; the rule bounds the domain at 43 names plus "other".
- getobject_lookup_us, _request_objects, _lookups_total{result},
_rejected_total{reason} and _charge, recorded at their call sites.
All three histograms get explicit bucket views: the SDK default stops
at 10,000, which every one of them exceeds.
- Per-job-type waiting/running/deferred gauges for the 35 non-special
job types. `deferred` is the leading indicator, since addJob never
rejects -- it defers, so backpressure otherwise shows up only as
latency after the fact.
`JobQueue::collect()` snapshots the counters under the queue lock and
publishes gauges after releasing it. Writing them while holding the lock
would invert a lock order against the collector's own lock, which the
collector's flush thread already holds when it calls this hook.
Tests assert exact values, including that the charge is priced on the
requested count rather than the capped iteration count.

Add reference entries for the observability surface introduced on
phase-9: the `handler` label on the job instruments, the five
`getobject_*` request metrics, and the per-job-type queue saturation
gauges.
Names here follow this branch's StatsD pipeline, which preserves case
and carries the `xrpld_` prefix, so they differ from the lowercased
OTel-native names used from phase-7 onward. The sections state where
the implementing code lives, since it is introduced downstream.
Also correct pre-existing entries: `job_count` exports as
`jobq_job_count` via the collector group prefix, the non-special job
type count is 35 (not 36), and `JtLedgerData` has five producers.

Signals that separate a sync that is merely slow from one that will never
finish:
- sync_acquire{missing_state_nodes_max, missing_tx_nodes_max, in_flight,
received_data_depth}: how many SHAMap nodes each in-flight acquire is
still waiting for. getMissingNodes already computed this and the callers
discarded it after a trace log. A count that stays flat means the
acquire is wedged; a shrinking count means it is progressing. Recorded
once per sweep, never inside the per-node walk, and reset when a tree
completes so a finished acquire does not read as stuck forever.
- shamap_cache_hit_rate{treenode}: hit rate of the in-memory tree-node
cache, which sits above the node store, so it is distinct from the
existing NuDB ratio. A cold cache on a fresh node sends every traversal
step to disk.
- sync_acquire_no_progress_total: timer ticks where an acquire made no
progress, previously only logged.
- sync_addnode_total{good,duplicate,invalid}: whether arriving nodes are
useful, duplicated or rejected, so wasted fetch work is visible.
- sync_acquire_source_total{local,network}: whether a ledger was served
from the local store or had to be fetched.
Adds getBad()/getDuplicate() to SHAMapAddNode and an acquireProgress()
accessor on InboundLedgers so the xrpld gauge can read these without
libxrpl depending on telemetry.
ledger_seq is deliberately not a metric label: it is unbounded. Per-ledger
identity stays on the ledger.acquire span; the metrics expose bounded
aggregates instead.
The full-below cache hit rate is not exported: KeyCache updates different
counters than getHitRate() reads, so it would always report zero. That
libxrpl bug is documented rather than papered over.

Five signals that explain why a node is not advancing toward full, none of
which were observable before:
- state_changes_total now carries {from,to} mode labels, emitted at
setMode using the existing strOperatingMode helper. A bare count could
not distinguish a healthy climb from a node flapping between tracking
and connected. Removes the now-unused incrementStateChanges wrapper.
- sync_state{initial_full_duration_us}: time to first reach full, which
StateAccounting already computed but exposed only in server_info.
- sync_state{network_ledger_gate}: whether the node is still refusing to
build ledgers because it has no network ledger.
- sync_state{server_stall_seconds} and server_stall_events_total: how
long the main thread has been unresponsive. LoadManager computed this
and only logged it, so a stall was invisible until the fatal threshold.
The episode rule is a pure function so it can be tested without adding
a test-only mutator to LoadManager.
- sync_state{ledgers_behind}: how far our validated sequence trails the
best sequence any peer advertises, read from already-cached peer ranges
so no extra network traffic is added.
Also fixes the naming checker: it derived only the first label of a
multi-label instrument, so a dashboard querying the second label was
wrongly rejected.
Note: the clang-tidy hook cannot run in this worktree (no build
directory); the remaining pre-commit hooks, the naming check, dashboard
schema and harness syntax all pass.

Three defects found reviewing the WP-A1 commit:
- Handshake.cpp moved a std::string into std::runtime_error, which has no
rvalue constructor. The move never happened and clang-tidy rejects it
under performance-move-const-arg, so CI would fail even though the
local hook only runs clang-tidy with TIDY=1. Takes the message by const
reference instead, and drops the <utility> include that existed only
for that move.
- ValidatorList disables quorum by returning SIZE_MAX. Casting that to
int64_t wrapped it to -1, so the headroom panel computed
0 - (-1) = +1 and coloured yellow on a node that can never validate:
the sign inverted in exactly the bootstrap failure these signals exist
to catch. Reports the disabled state as int64 max so headroom goes
strongly negative instead.
- The runbook claimed an expired list loads no keys. Expired counts as
accepted, so its keys are loaded and then dropped by the expiry sweep,
which calls for a different fix than replacing validators.txt. Pending
is likewise a future-dated refresh, not a rejection. Documents both,
plus how the quorum-disabled state now reads.

A freshly started node most often stalls before it ever peers or reaches
quorum, and that whole chain had no telemetry. Adds the six signals that
make it observable:
- dns_resolve_total / dns_resolve_latency_ms: configured-peer hostname
resolution, emitted from OverlayImpl so libxrpl stays independent.
- overlay_connect_total / overlay_dial_latency_ms: outbound dial outcome
by terminal reason, plus dial duration.
- handshake_negotiation_fail_total: protocol and network-id negotiation
rejections, labelled by reason, so a misconfigured network is no longer
indistinguishable from unreachable peers.
- unl_fetch_total and the unl_quorum gauge: validator-list fetch outcome
per site and trusted key count against the required quorum. Without
these a bad validators.txt leaves the node syncing forever with no
signal.
- clock_close_offset_seconds: network close-time offset, which server_info
hides below 60s but which stalls consensus participation.
Panels land in the Bootstrap row of the Ledger Sync Health dashboard, the
metrics are asserted by the workload validator, and both the reference and
the runbook flow describe them.
Levelization baseline regenerated: overlay now includes MetricMacros.h, so
the overlay/telemetry pair is reported one-way instead of bidirectional.

Match the panel height the operator settled on in Grafana (18 rows) so
all 20 ranked bars render without an inner scrollbar, and reflow the
Sync Diagnostics row and the panels below it accordingly.
Adds the anchors the sync-diagnostics signals attach to, with no signals
emitted yet:
- New "Ledger Sync Health" dashboard (uid ledger-sync-health) with the
standard template-variable block copied from an existing board, plus
empty "Bootstrap (Domain 0)" and "Sync pipeline" rows.
- Signal index section in the data-collection reference, an operator-flow
stub in the telemetry runbook, and a glossary anchor.
- A sync_diagnostics group in expected_metrics.json and a matching
assertion helper in validate_telemetry.py so CI fails when a signal
regresses to absent.
Also registers the new dashboard uid with the harness so the board is
covered by validation.

The bar labels on 'Overlay Traffic Heatmap (All Categories, Bytes In)'
were raw metric names carrying a redundant '_bytes_in' suffix, and the
half-width 8-row panel truncated both the category and the node
identity.
- Strip the '_bytes_in' suffix from the derived series label; the panel
title already states the metric is inbound bytes.
- Widen the panel to full width and grow it to 12 rows so 20 bars render
with their full category and node labels.
- Shift the Sync Diagnostics row and the panels below it down by 4 to
keep the layout gap-free.
- Note the label derivation in the panel description.
The panel plotted only Full and Tracking, so the states a node actually
passes through while catching up were invisible. On the dev box's cold
sync the node spent ~19 minutes in Connected and ~3 seconds in Syncing,
while Tracking totalled 2 microseconds -- the one non-Full line the
panel did draw was the least informative of the five.
Add Syncing, Connected and Disconnected series (state-ladder order,
matching the Operating Mode Transitions panel) and rename the panel to
"State Duration Rate (All States)". Because the node is always in
exactly one state, the five rates sum to ~1.0, so the panel now reads as
"which state is time going into right now", and a handover between two
lines marks a state change with its width showing the dwell time.
Description expanded to the full section set (keywords, computation
boundary, references) used by the other panels on this dashboard.
Verified live: rate(state_accounting_connected_duration)/1e6 reaches
1.0 then 0.387 across the catch-up window and syncing reaches 0.0103 --
both previously undrawable.
The dashboard showed 54 individual signals but no single answer to
"is this node healthy and doing its job?". A reader had to correlate
server state, ledger age and peer counts by eye.
Add a stat panel at the top that reduces the two conditions that define
a healthy observer node to one green/red verdict:
server_state == 4 (Full) AND validated_ledger_age < 30s
Both terms use `== bool` so each yields 0/1, joined with
`* on(service_instance_id)` so the verdict is per node. Value mappings
render 1 as "Healthy" (green) and 0 as "Not Healthy" (red) with
background colouring, so the state is readable at a glance.
Placed at y=0 per the dashboard convention that gauges/stats lead;
existing panels shift down by 4 rows with no other change.
Verified live against Grafana Cloud: returns 1 for aws-dev-xrpl-1
(Full, validated seq 105,824,596).
The four aggregated Sync Diagnostics panels grouped by xrpl_work_item,
which no layer in this repo emits (it is injected by the perf-iac
harness). That tripped Rule D of the telemetry naming check:
D ledger-data-sync.json xrpl_work_item
must exist in L1, a metric label, or be a builtin
Align with the convention used by every other aggregated panel in the
dashboard set: group by (service_instance_id, xrpl_branch,
xrpl_node_role) and leave the xrpl_ident label_join untouched. The
legend is unaffected -- label_join over a label dropped by the
aggregation contributes an empty segment, which the trailing
label_replace already strips.
Verified live: both the NuDB ratio and the job-queue p95 queries still
return per-node series rendering as "[aws-dev-xrpl-1]".
The 0-4 values now render as named states via value mappings, so the numeric
axis label is misleading. Rename to "Server State".

Add value mappings (0 Disconnected, 1 Connected, 2 Syncing, 3 Tracking,
4 Full) and matching red->green thresholds to the Sync State panel, so the
line, tooltip, and legend render state names and colors instead of bare 0-4.
Keeps the minimal custom-key convention; only the Sync State panel changes.

Rework the 10 Sync Diagnostics panels' legends to match the format used by the
existing panels: wrap each query in label_join + label_replace to build the
xrpl_ident label ([service_instance_id, xrpl_branch, xrpl_work_item] with empty
values stripped) and set displayName to "${series} ${xrpl_ident}". Verified
against a live node: renders as "Series [aws-dev-xrpl-1]" with no empty-label
gaps, identical mechanism to the original 15 panels. Only the new panels change.

Add a 10-panel "Sync Diagnostics" row that shows ledger-sync slowdown and its
causes, laid out top-to-bottom as symptom -> latency -> root cause:
- Red flags: Sync State, Validated Ledger Age, Ledger Close Rate
- Latency: Job Queue Wait p95 by type, NuDB Read Latency, I/O Scheduler p95
- Root cause: NuDB Cache Hit Ratio, NuDB Read Pressure, Job Queue Depth,
Load Factor & Peers
All panels use native beast::insight metrics introduced on this branch
(nodestore_state, ledgermaster_*, jobq_*_q, ios_latency, load_factor_metrics,
peer_finder_*) plus the consensus.mode_change span metric. Queries filter by
the dashboard's $node and tier variables and were verified against a live
node. Nodestore ratio panels use sum-by(identity) matching to bridge the
metric= sub-label.
Format matches the dashboard convention: minimal custom keys, ${DS_PROMETHEUS}
datasource uid, and the standard What/How/Reading/Healthy/Watch/Source/Function
description structure. Pure-append; existing panels untouched.

Document the two new ledger-correlation attributes in the data-collection
reference: add them to the transaction and TxQ attribute tables (with per-span
coverage), update the attribute count, and correct the txq.enqueue parent note
(parents to tx.process on the submission path via explicit context; a root on
the open-ledger rebuild path, correlated via current_ledger_seq).

Add current_ledger_seq / current_ledger_hash to the tx.process, tx.receive,
and txq.enqueue span-reference rows, correct the txq.enqueue parent note
(parents to tx.process on the submission path via explicit context; a root on
the open-ledger rebuild path), and add a "Correlating a transaction to the
ledger it was worked on" recipe joining the txID-keyed tx/txq spans to the
ledger trace via current_ledger_seq.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add shared current_ledger_seq / current_ledger_hash span attributes so a
transaction's work can be joined to the ledger trace that produced it, and
fix discrepancy D1 (txq.enqueue was a detached trace root).
- Define current_ledger_seq / current_ledger_hash once in SpanNames.h and
re-export via `using` from TxQ/TxApply/Tx span-name headers. These name the
ledger being worked on (open/tentative apply or in-flight consensus build),
distinct from ledger_seq (the built/validated ledger on ledger.build /
consensus.round). Named after the RPC field ledger_current_index.
- txq.enqueue: set current_ledger_seq/hash from the view, and parent the span
to the caller's tx.process span via an explicit captured SpanContext (new
trailing TxQ::apply param) instead of a detached root. The parent is
explicit, not ambient-inherited, and the ScopedSpanGuard scope is RAII-bound
to the synchronous apply, so it cannot leak onto a reused worker (D1 fix).
On the open-ledger rebuild path no tx.process context exists, so it stays a
root and the attribute provides the correlation.
- tx.preclaim / tx.transactor: set both attributes from their ledger view.
tx.preflight is stateless (no view) and is the documented exception.
- tx.process / tx.receive: set current_ledger_seq from the current open ledger
index at submit/receive time (no hash: not yet applied to a ledger).
- Contract test pins the two new attribute key strings.
Neither key is a spanmetrics dimension, so there is no metric-cardinality
impact. Dashboards/collector/docs land on the later phases per the chain split.

The colocated span-name headers (RpcSpanNames.h, ConsensusSpanNames.h,
PeerSpanNames.h, etc.) hold only compile-time constant strings and live
next to their subsystem rather than under a telemetry/ directory, so the

do not count against patch coverage; like the rest of the telemetry
surface they are not exercised in the coverage build.

The existing ignore list only covered src/xrpld/telemetry/, but the same
rationale — telemetry code is conditionally compiled behind
XRPL_ENABLE_TELEMETRY, which the coverage build does not enable — applies to
src/libxrpl/telemetry/ (SpanGuard.cpp, Telemetry.cpp, etc.) and the
include/xrpl/telemetry/ headers. Their lines are never executed in coverage
builds, so they were dragging patch coverage down on the telemetry PRs.

Add a "Protocol Span Flow" section to the telemetry operator runbook: 8
Mermaid diagrams that map every OTel span onto the real xrpld control flow
and XRPL protocol order (verified against code and docs/consensus.md), for
use as the canonical key when linking the span hierarchy.
- Master overview, client/peer ingress, shared apply pipeline, consensus
round, accept/build/finalize, and pathfinding/ledger-acquire side flows.
- Every node/branch is labelled with the span that represents that state or
transition (or explicit "(no span)"); drops/abandons are marked terminal.
- Shows real loops, retries, recovery, and drop branches: multi-round
consensus settling (avalanche threshold rounds + MovedOn/Expired retry with
wrong-ledger recovery), 3-pass tx apply retry, TxQ cross-ledger retry,
quorum-gated async validation with abandoned-ledger, ingress backpressure
drops, and cross-node context propagation.
- Adds a divergence table noting where OTel span parenting does not match the
real protocol flow (deterministic/hash trace-id roots, JtAccept/JtUpdatePf
job hand-offs, sequential peer->consensus receive stages).
Replace the stale planning-era diagram in OpenTelemetryPlan/08-appendix.md
(which named spans that were never built) with a pointer to the runbook.

The Alloy spanmetrics connector (perf-iac nodes run Alloy instead of the
collector-contrib image) carried the same old [.. 1s, 5s] bucket list, whose
buckets are documented as "copied from" the collector config. Sync it to the
15-bucket layout (adds 2s, 3s, 4s, 10s, 30s) so Alloy-fed nodes get the same
accurate second-scale consensus and ledger.acquire percentiles as
collector-fed nodes. unit was already "ms". Kept strictly ascending.

M1: ~PendingTraceId now increments a process-wide atomic counter when a
pinned deterministic trace_id is destroyed unconsumed, so the silent drop

The deterministic trace_id bytes, the GenerateTraceId() consume logic, and
the unconditional reset() are all unchanged.
M2: tighten the Doxygen on SpanGuard::childSpan(std::string_view) to state
it parents to the current ambient context of this store (meaningful only

Resolved: Telemetry.cpp keeps both meterProvider_ (phase-7) and contextStorage_

Activate the accept span as ambient context at the top of doAccept using the
non-owning ScopedActivation, so doAccept's log lines (and any spans created in
the body) carry the accept span's trace_id. doAccept runs to completion on the
JtAccept worker with no coroutine yield, so the activation is thread-local and
safe; the acceptSpan still owns and ends the span. The accept.apply child span
keeps its explicit childSpan(acceptApply, acceptSpanContext_) parentage --
activation only adds log correlation and does not alter parent linkage.

Brings coroutine-aware context storage, scoped rpc.command, coro-store-swap
tests, and the scoped pathfind.request forward.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add two GTests on the SpanGuardScopeTest fixture and install a
CoroAwareContextStorage so the tests exercise coro-aware ambient context:
- scopedGuard_survives_localvalue_store_swap: a ScopedSpanGuard's scope
is hidden when its LocalValue store is swapped out and visible again
when swapped back in, and pops cleanly under the owning store.
- activate_sets_ambient_without_owning: SpanGuard::activate() makes the
span ambient for the activation's lifetime without ending it; the
owning guard ends it exactly once.
Fix the cross-store death test to match the store-identity assertion
message ("constructing context store", not "constructing thread") after
the A3 refactor; the fixture's storage install is what lets the assert
fire at all.
Revert RipplePathFind's pathfind.request from freshRoot SpanGuard back to
ScopedSpanGuard: the coro-aware storage moves the scope with the
coroutine across yield, so it nests under rpc.command and stays
trace-correlated.

Brings coroutine-aware OTel context storage forward: CoroAwareContextStorage,
its install in Telemetry, ScopedSpanGuard same-store assertion, and the
non-owning ScopedActivation helper.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add SpanGuard::activate() returning a ScopedActivation RAII helper that
activates an already-owned span (from a thread-free SpanGuard) as the
current context WITHOUT taking ownership. The activation pushes the span
onto the current LocalValue context store on construction and pops it on
destruction; it never ends the span (its owning SpanGuard does).
This lets a job-handoff span be made ambient for the duration of a
synchronous, non-yielding worker body so log lines there carry the
span's trace_id. Non-copyable and non-movable, mirroring ScopedSpanGuard.
owner is captured after the Scope push via declaration-order member
initialization (scope declared before owner), matching the A3
capture-after-materialization invariant. A #else no-op stub keeps the
API zero-overhead when telemetry is compiled out.

On Windows the telemetry unit test src/tests/libxrpl/telemetry/MetricMacros.cpp
fails to compile with boost/asio/detail/socket_types.hpp C1189
"WinSock.h has already been included". Root cause traced with clang -E -H:
MetricMacros.h pulls MetricsRegistry.h -> OTel spin_lock_mutex.h, which
defines _WINSOCKAPI_ and includes <windows.h> (WinSock 1); it then pulls
ServiceRegistry.h -> <boost/asio.hpp>, whose socket_types.hpp requires
winsock2.h first. Production consumers (RCLConsensus.cpp, PerfLogImp.cpp)
happen to include Boost.Asio via other xrpld headers first, so only the test
TU -- which includes MetricMacros.h first -- hit it.
Pre-include boost/asio/detail/socket_types.hpp under _MSC_VER at the top of
the header so winsock2.h wins for every consumer. Mirrors the existing guard
in MetricsRegistry.cpp.

Install CoroAwareContextStorage as the process-wide OTel runtime context
storage in TelemetryImpl::start(), before SetTracerProvider and before any
span is created, so the ambient context follows JobQueue coroutines across

stop() because resetting while spans may exist is SDK undefined behaviour.

Brings in the telemetry/metrics init-order fix (start before [rpc_startup]).
Conflict in Application.cpp: phase10 had reordered start() to run
telemetry+metrics first; phase9 relocated that block into a new
startTelemetry() called from setup() before the [rpc_startup] loop.
Resolved by taking the fix — the block lives only in startTelemetry()
(called once from setup(), after overlay_ is built), removed from start().
telemetry_->start() and metricsRegistry_->start() each appear exactly once.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Metric-emitting code that first runs during ApplicationImp::setup() (the
[rpc_startup] loop) executed while the OTel meter was still empty, because
telemetry_ and metricsRegistry_ were started later in start(). A call-site
metric macro caches its instrument on first use via std::call_once, so that
first pre-meter use latched a null instrument for the process lifetime and the
metric silently never recorded (observed: rpc_in_flight_requests, emitted from
PerfLogImp::rpcStart, never appeared).
Extract telemetry_->start() and the metricsRegistry_->start() block into a new
private ApplicationImp::startTelemetry() and call it from setup() just before
the [rpc_startup] loop, so the meter is live before any metric-emitting code
runs. The call sits after overlay_ (and the other subsystems the observable-
gauge callbacks read) is constructed, since starting the metrics reader thread
earlier would let its callbacks call getOverlay() before overlay_ exists.
perfLog_->start() stays in start() — the macro call sites do not depend on it.

P95 of second-scale spans was a meaningless interpolation. The spanmetrics
histogram topped out at [.. 1s, 5s], so consensus.round (~3.9s) and
consensus.establish (~1.9s) all fell into one 1s-5s bucket and
histogram_quantile interpolated linearly across that 4s-wide gap — the
"Build vs Close" / "Ledger Close Duration" panels' P95 read ~4800ms purely
as an artifact (verified: sum/count avg = 3824ms). ledger.acquire was worse:
~17% of samples exceeded the 5s ceiling, so its p95/p99 were unmeasurable.
Add 2s, 3s, 4s (resolve the 1-5s pile-up) and 10s, 30s (give the
ledger.acquire catch-up tail a measurable home). All ten existing boundaries
are preserved and the list stays strictly ascending (the connector
binary-searches buckets and silently misbuckets otherwise). Pin unit=ms so a
future collector default-unit flip can't rename the metric to _seconds.
Buckets chosen from the live mainnet distribution, not guessed. Native
beast::insight histograms (ms-scale RPC/IO timers in Telemetry.cpp) are 100%
under 5s, so they keep the original buckets — this is collector-only.
Applies on collector restart (cumulative series reset once, handled by
rate()). Runbook and regression-threshold bucket notes updated to match.

The "Ledger Close Duration" panel measured the consensus.ledger_close span
duration, which only wraps the sub-millisecond onClose() prologue — not the
ledger close. Repoint it to the consensus.round span (full round, open to
accept) so it reflects actual close time (~3-5s on mainnet). The consensus_mode
filter is preserved (consensus.round carries that attribute, verified live).
The sibling rate panels (Consensus Mode Over Time, Accept vs Close Rate,
Validation vs Close Rate) keep using consensus.ledger_close: a rate of that
span is a valid per-close event counter, only its duration was wrong.
Runbook updated to match.

The "ledger close time" was mis-derived and partly un-queryable:
- Build vs Close Duration derived close time from the consensus.ledger_close
span, which only wraps the onClose() prologue (~0.8ms live) — not the close.
Repoint the close series to consensus.round (full round, live P95 ~4.8s).
- The network close-time value (close_time) lived only as a span attribute,
un-queryable in Prometheus and unfit as a spanmetrics label (monotonic
timestamp -> unbounded cardinality). Expose it as last_close_time on the
existing server_info observable gauge (native gauge, no new instrument).
- Add a "Ledger Close Interval & Age" panel to ledger-operations and
node-health: interval = 1/rate(ledgers_closed_total) (counter-based,
scrape-independent); age = time() - (last_close_time + epoch_offset).
A gauge delta is deliberately NOT used for the interval — a timestamp gauge's
delta aliases to the scrape period, not the close cadence (verified live).
Guardrail comments in both collector configs record why close_time must never

Document that deterministic-trace_id spans (tx.* apply pipeline, tx.process,
tx.receive, consensus.round) are now genuine trace roots with empty
parent_span_id via the custom DeterministicIdGenerator, superseding the old
synthetic-parent behavior that showed 'root span not yet received' in Tempo.
Also update the fresh-root note: peer entry spans use ScopedSpanGuard::freshRoot().
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
These peer-level entry spans (introduced on phase-6) used the removed
SpanGuard::rootSpan(). They are scoped on the peer thread and end there, so
use ScopedSpanGuard::freshRoot() — a scoped fresh trace root that does not
inherit any span left active on the peer thread.

With unscoped SpanGuard + spanContext() (own-span capture), the consensus
round/establish/accept sites just capture and drop the detach dance;
openSpan + peer proposal/validation receive are thread-free handoffs (no
detach); rootSpan->freshRoot.

OTel distinguishes a span's own context from the thread's
current/ambient context; SpanGuard is unscoped so spanContext()
(own span, default) is what cross-thread childSpan parenting needs,
and threadLocalContext() (static) snapshots RuntimeContext::GetCurrent()
for propagation. Renames captureContext.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
SpanGuard is unscoped (never pushed onto the thread-local context stack), so
RuntimeContext::GetCurrent() returned an unrelated ambient span. Build the
captured context from impl_->span so captureContext() is correct for every
caller regardless of scoping — childSpan(name, ctx) then parents explicitly to
this span across threads. Matches getTraceBytes()'s own-context behavior.

The generator's doc said it was 'dormant, caller lands on a later branch'.
Reworded to branch-agnostic language: hashSpan() is the primary caller that
forces the root branch to mint deterministic trace roots.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
SpanGuard is now thread-free (holds no Scope), so the tx.receive (PeerImp)
and tx.process (NetworkOPs) handoff sites no longer need .detached() before
being stored and ended on a worker thread — just construct the guard. The
stale "Scope leak" comments are replaced accordingly.
Make the six txq.* spans ScopedSpanGuard so their sub-spans nest via the
ambient context: txq.apply_direct/batch_clear under txq.enqueue, and
txq.accept_tx under txq.accept. All six are verified synchronous, ended at
scope, and never moved/handed off, so scoping is safe. applyDirect's span
is pure RAII (no method calls), so it is declared const.

The single-arg hashSpan fabricated a synthetic DefaultSpan parent (random
span_id) to carry the deterministic trace_id. That left every standalone
hash span with a phantom parent_span_id pointing at a span that is never
exported, so Tempo reported "root span not yet received".
Inject the deterministic trace_id through the DeterministicIdGenerator
instead: start the span on the SDK root branch (Context{kIsRootSpanKey,true})
with a PendingTraceId pinning hashData[0:16]. The SDK's no-valid-parent
branch calls GenerateTraceId(), which returns the pinned id, yielding a
TRUE root (empty parent_span_id) whose trace_id == hashData[0:16].
The deterministic bytes are unchanged (still raw hashData[0:16]). The
cross-node overload (real remote parent, remote=true) is untouched and must
keep producing a child of the sender's span. Drop the now-unused
<xrpl/basics/random.h> include; add <array> and DeterministicIdGenerator.h.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Rewrite SpanGuardScope.cpp for the unscoped SpanGuard / scoped
ScopedSpanGuard split and the DeterministicIdGenerator: install the
generator in the TestTelemetry mock (4-arg TracerProviderFactory), drop the
obsolete detached()/detachInPlace() tests, and add freshRoot, scoped-ambient,
scope-handoff, ends-once, deterministic-root, and cross-thread death tests
with exact assertions.
Fix the last detached() caller: RipplePathFind now uses SpanGuard::freshRoot
(SpanGuard is thread-free, so it is held across the coroutine yield and ended
on resume with no scope to strip).

Add MetricMacros.h exposing 13 call-site metric macros covering all 7 OTel
instrument kinds (Counter INC/ADD, UpDownCounter, Histogram, sync Gauge, and
Observable Counter/UpDownCounter/Gauge), each with a no-op branch when
XRPL_ENABLE_TELEMETRY is undefined. Sync macros lazily create-once via
std::call_once and cache the instrument at the call site; observable macros
register a callback eagerly. Sync Gauge is ABI-v2-gated with an actionable
static_assert under this repo's ABI v1 build.
Add GTest coverage (8 tests) driving the macros against a bare SDK
MeterProvider via a duck-typed FakeApp/FakeMetricsRegistry, asserting exact
create-once and disabled-gating behavior. No CMakeLists change needed: the
telemetry test-module glob already discovers the new source.

Entry points (http_request/ws_message/ws_upgrade) were inheriting a leaked

Add a custom OTel IdGenerator that returns a thread-local pending trace_id on
the SDK no-parent (root) branch and a random one otherwise, plus a PendingTraceId
RAII guard that pins that id for the next forced-root span and asserts on
destruction that it was consumed. Wire the generator into
TracerProviderFactory::Create via its 4-arg overload.
This lets hash-derived spans become true trace roots so they line up into one
trace across nodes. It is installed but dormant on this branch: the caller
(hashSpan) arrives on a later branch (phase-3). GenerateSpanId is always random
and is_random_ is false so the W3C random-trace-id flag is not set on
deterministic ids.

Separate the two responsibilities the old SpanGuard fused: span ownership
(thread-free) and scope activation (thread-bound TLS push).
- SpanGuard now owns ONLY the span. Its Impl drops the optional<Scope>,
the owner thread-id, the Detached tag and the scope-less ctor; ~Impl is
just `if (span) span->End()`. The guard never binds a thread-local
context stack, so it may be moved to and destroyed on any thread.
- ScopedSpanGuard is a new pimpl type that wraps a SpanGuard plus an
optional<Scope>. Member order (guard first, scope second) pops the
scope before the span ends. It is non-copyable and non-movable;
factories return unnamed temporaries so guaranteed copy elision covers
`auto s = ScopedSpanGuard::freshRoot(...)`.
- `operator SpanGuard() &&` replaces detached()/detachInPlace(): it pops
the scope eagerly on the origin thread and yields a thread-free
SpanGuard for handoff to a job or another thread. detached(),
detachInPlace() (both overloads) and the Detached apparatus are deleted.
- Move-assignment is re-enabled on SpanGuard (no Scope to re-bind), in
both the real class and the no-op stub.
- rootSpan() renamed to freshRoot() in both classes (behavior unchanged:
still forces kIsRootSpanKey).
- hashSpan behavior is intentionally unchanged (only builds the now
unscoped Impl); the true-root IdGenerator fix is a separate later task.

Add two free functions in xrpl::telemetry that wrap the required
"detach a live SpanGuard held in a container" idiom so call sites write
one line instead of the make_shared/emplace rebuild by hand:
void detachInPlace(std::optional<SpanGuard>&);
std::shared_ptr<SpanGuard> detachInPlace(std::shared_ptr<SpanGuard>);
Both are no-ops on an empty/null/inactive guard. The #else branch adds
matching inline no-op stubs so callers compile with telemetry disabled.
Pure API addition, no behavior change; consumer call sites are rewritten
on phase4 in a follow-up.
The unit tests for these helpers land on phase2, where the telemetry
test module (in-memory-exporter harness + SpanGuardScope.cpp) exists —
mirroring how the detached()/rootSpan() tests were placed.

xrpl_branch and xrpl_node_role are stamped by the perf-iac harness --
infrastructure outside this repo's OTel code -- so they have no L1
(*SpanNames.h), L2 (collector config), or L6 (MetricsRegistry.cpp) source
Rule D can derive them from. Unlike the generic builtins set (Prometheus/
Grafana mechanics every OTel setup has), these are repo-specific and
narrow, so they get their own EXTERNAL_INFRA_LABELS constant: a visible,
documented, deliberately narrow exception to the 'no hardcoded allowlist'
design principle, not a silent workaround. Add test coverage.

xrpl_branch and xrpl_node_role are collector/infra-injected resource
labels used by perf-iac dashboards to identify the build under test and
its role in the perf cluster. They have no L1 span-attribute source or

builtins), so Rule D flagged them across every perf-iac dashboard.
Register them in the builtins set, matching the existing pattern for
infra-level dashboard labels. Add test coverage.

getMeter() became a pure virtual on THIS branch (native-metrics), which
makes the TestTelemetry mock abstract and would break a telemetry=ON
build of phase7/phase8 in isolation. The override was previously only on
phase9 (where it was mis-attributed); relocate it to phase7 where the
pure virtual is introduced, so every branch from here forward builds.

The opentelemetry-cpp::exporter_in_memory component declares no libs (the
Conan recipe ships libopentelemetry_exporter_in_memory.a but does not
associate it with the component), so linking that target put nothing on
the link line and xrpl_tests still failed with an undefined reference to
InMemorySpanExporterFactory::Create. Locate the archive with find_library
(HINTS the OTel package lib dir) and link it by path, ahead of the umbrella
so its undefined SDK references resolve. Verified: the archive now appears
on the generated link line and xrpl_tests links + the SpanGuardScope tests
pass. Supersedes the no-op component-target link in the prior commit.

The umbrella opentelemetry-cpp target's link set omits the in-memory

opentelemetry-cpp::exporter_in_memory component explicitly. Test-only:
production code never uses this exporter.

Fees::accountReserve gained a second accountCount parameter (merged from

Post-review fixes for the SpanGuard scope-leak change:
- SpanGuard.h: restore the injectCurrentContextToProtobuf real-class
declaration, its #else no-op stub, and the protocol::TraceContext
forward-declaration dropped during the 3->4 union merge (compile break).
- Re-parent consensus.phase.open and consensus.establish under the round
span via a new RCLConsensus::Adaptor::roundSpanContext() accessor: the
round span is now detached, so ambient parenting no longer works; the
phase spans link explicitly to the captured round context. csf::Peer
gains a matching no-op accessor so the generic engine still compiles.
- Switch five childSpan(op::X, ctx) sites to the full consensus::span::X
constants: childSpan(name, ctx) takes the name verbatim, so the suffix-
only op:: constants emitted short, non-dotted span names.
- TestTelemetry mock: add getConsensusTraceStrategy() override (base pure
virtual introduced on this branch) so the mock is not abstract.
- validate(): rewrite the trace_context comment to drop attack-surface
framing and the PR-discussion reference.

roundSpan_, establishSpan_, openSpan_ and the accept span are emplaced on
one job worker and reset()/moved to another, leaking their thread-local OTel
Scope. Each is now detached AFTER its context is captured. Spans that
previously nested under them via the ambient thread context are re-pointed to
the captured SpanContext explicitly:
- round children (proposal.send, ledger_close, mode_change) -> roundSpanContext_
- establish children (update_positions, check) -> establishSpanContext_
- accept.apply -> acceptSpanContext_
onForceAccept (synchronous) keeps the accept span's behaviour; only onAccept
(moved into the JtAccept job) needs the detach. Member move-assignment is
deleted, so re-assignment uses emplace().

The consensus.proposal.receive / consensus.validation.receive guards are
moved into checkPropose/checkValidation jobs, so detach their Scope on the
peer thread before the job hand-off. The standalone (no-propagated-context)

fresh trace root instead of inheriting an ambient span; the hashSpan
propagated-context branches are unchanged (cross-node linking preserved).

doRipplePathFind holds its pathfind.request span across context.coro->yield();
the coroutine resumes on a different JobQueue worker. rootSpan() gives it a
fresh trace root (no stale ambient parent), and detached() strips the
thread-local Scope so the guard neither lingers on the worker's context stack
across the yield nor pops the wrong stack on resume.

including the rootSpan().detached() combination used here.

acquireSpan_ is emplaced on the acquiring caller thread but reset() in

These inbound peer-message entry points (kConsumer) used span(), which

Both spans are moved into job-queue lambdas and destroyed on a worker

detached() strips the thread-local OTel Scope so a guard can be safely
moved to and destroyed on another thread; it pops the Scope on the origin
thread and moves the span into a scope-less guard. rootSpan() starts a span
as a fresh trace root (kIsRootSpanKey) so inbound entry points never inherit
an ambient span left active on the thread.
Impl now holds an optional<Scope> (nullopt for detached guards). Updated the

Sync the Node Health dashboard with panels and field settings refined in
Grafana, and document the ledger-convergence panels:
- Add descriptions for "Validated Ledger Seq — Current (Stat)" (per-node lag
behind the network tip) and "Validated Ledger Seq — Convergence (Max − Min)"
(seq spread across nodes), in the standard 7-field panel format.
- Peer Count: threshold colours (red < 5, yellow < 10, green >= 10) so a low
peer count reads red rather than using a value gradient.
- Minor field-config fixes on Last Close and NuDB Storage panels (axis label,
threshold cleanup) as adjusted in Grafana.

Regroup all 47 panels under correct subsystem rows and fix the broken row
structure. Previously the "NodeStore I/O" row had no gridPos and collided at
y=32 with an appended "Extended Metrics" catch-all row, so NodeStore I/O
rendered empty and its panels landed under the wrong header.
- Rows: Overview (top), Operating Mode, NodeStore I/O, Jobs, Caches, Server
Info, Complete Ledgers & DB, Ledger Economy. Drop the stray "Extended
Metrics" row; each panel now sits under its subsystem.
- Normalize panel heights to three buckets: 12 (standard), 16 (emphasis /
detail plots), 24 (Operating Mode state timeline). Widths stay half (12) or
full (24).
- Contiguous, non-overlapping gridPos; all 47 panels preserved.

Rework the legend identity bracket across all 14 dashboards so it reads
"<series> [instance, branch, work_item]" (comma-separated, Node Role dropped)
and collapses cleanly when perf-iac labels are absent -- "<series> [instance]"
with no empty "[, ]" gaps.
- Build one xrpl_ident label per query via label_join + a single label_replace
that trims leading/trailing empty segments and brackets the result. Done at
the outermost (post-aggregation) level so it survives each panel's by() clause.
- Add service_instance_id to the by() of 6 panels that grouped only by node_role,
so same-branch validator/peer series stay distinguishable after dropping the
node_role legend token.
- Fold the two legendFormat two-bracket panels (Transaction Results by Type,
Tx Apply Pipeline Latency by Type and Stage) into the same single-bracket form.
- Rename the annotation query label "Perf runs (perf-iac)" to
"Annotate perf-iac runs".
- Revert dashboard-level descriptions to plain text (the folder-list info tooltip
escapes HTML, so <br>/markdown render literally).
Verified: output byte-identical to the prior multi-call cleanup over a 2-day
live perf window; all 14 files valid JSON.

The legend now uses raw labels in the dashboard Display name (see the paired

Mirror the local collector change on the Grafana Cloud collector config and the
in-repo Alloy config: build the group-label VALUES with brackets and comma
separators (resource_group="[node, mainnet]",
iac_group="[branch, role, work-item]") in both trace and metric resource
statements, so span-derived and native metrics carry the same bracketed values.
This lets the dashboards use a bracket-free Display name and avoids the empty
"[]" that a templated bracket would leave when a group is absent (Grafana's
renameByRegex runs pre-interpolation and cannot strip it). Separator changes
from "-" to ", ".

The Display name templated the brackets: "${series} [${resource_group}]
[${iac_group}]". When a group label was absent the "${}" rendered empty,
leaving a literal "[]" in the legend, and the cleanup renameByRegex could not
remove it (Grafana runs that transform on the pre-interpolation template, which
has no "[]" -- it only appears after interpolation at render time).
Bake the brackets and comma separators into the group-label VALUES in the
collector instead (resource_group="[node, mainnet]",
iac_group="[branch, role, work-item]"), so the Display name is bracket-free
("${series} ${resource_group} ${iac_group}") and an absent group renders as
nothing. Separator changes from "-" to ", ". Drop the dead cleanup transform.
Covers this branch's local collector config and its three dashboards

The Display name templated the brackets: "${series} [${resource_group}]
[${iac_group}]". When a group label was absent (e.g. iac_group on a non-perf
node) the "${}" rendered empty, leaving a literal "[]" in the legend. The
empty-bracket cleanup renameByRegex could not remove it: Grafana runs that
transform on the pre-interpolation Display name template, which contains no
"[]" -- the "[]" only appears after variable interpolation, at render time.
Fix it at the source: the collector now bakes the brackets and comma separators
into the group-label VALUES (e.g. resource_group="[node, mainnet]",
iac_group="[branch, role, work-item]"). The Display name becomes bracket-free --
"${series} ${resource_group} ${iac_group}" -- so an absent group is simply an
absent label and renders as nothing. Also switches the intra-group separator
from "-" to ", " (e.g. "[node, mainnet]"). Drop the now-dead cleanup transform
from every panel; value-mapping renameByRegex rules are preserved.
Collector-side label building lives in the paired commits on the collector
config branches. This commit is the dashboard half for the eleven dashboards

Panels that group by a distinguishing dimension (consensus_mode, tx_type,
command, method, stage, ...) already fold that dimension's value into the
curated series name via label_replace(..., "series", "<prefix> $1", "<dim>",
"(.*)"). The migration also added a separate [${__field.labels.<dim>}] bracket,
so those legends rendered the value twice, e.g. "proposing [proposing] [...]"
on Consensus Mode Over Time.
Remove the dimension bracket from all 29 affected panel Display names, leaving
${__field.labels.series} [resource_group] [iac_group]; the series name already
conveys the dimension. The migration script no longer emits the bracket either.

In the Alloy config the spanmetrics connector derives span_calls_total /
span_duration_* from the tagged TRACES and sends them straight to the batch
processor, bypassing the metric resource statements. The grouped legend labels
were built only in metric_statements, so span-derived RED metrics carried no
resource_group / iac_group and span-based dashboard panels rendered empty group
legends.
Build the same labels in trace_statements too (mirroring how the tier attrs are
already set in both), so spans carry them before spanmetrics derives from them.
The reference otel collector is unaffected: there spanmetrics is a connector
feeding the metrics pipeline, which runs transform/legendgroups on all inputs.

The docker/telemetry/alloy/config.alloy node config feeds Grafana Cloud via the
OTLP gateway (which promotes resource attributes to labels server-side). Add the
resource_group / iac_group build to its metric resource statements so nodes
using this Alloy path get the same grouped legend labels the dashboards expect.
This is a generic node config (no perf-iac attrs), so iac_group's guard never
fires here and only resource_group is built; the iac_group statement is kept for
parity and activates automatically on a perf-comparison node. Guards check != ""
as well as != nil since OTTL Concat emits a stray separator for an empty element.

Eighteen timeseries panels in consensus-health and transaction-overview

them so every panel's tooltip matches Mode:All / Sort:Desc / Max Height:600.

The "Overlay Traffic by Category (Bytes In)" bargauge names each bar by
category via 22 byName field-override displayNames (Transactions, Proposals,
...). The legend migration had also added a generic
${__field.labels.series} [...] Display name, which competed with those
curated names. Remove the generic Display name (and its now-unneeded
empty-bracket cleanup transform) from this panel so the category names stand;
this panel's identity is the traffic category, not the node/perf-iac grouping.

Mirror the local-config guard hardening on the Grafana Cloud collector config:
add != "" to the transform/legendgroups presence guards so an empty-string
perf-iac attribute (work_item | default('') on a no-work-item run) does not
produce iac_group="--". Empty-string sources now leave the group unset.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The transform/legendgroups guards checked only != nil. The perf-iac collector
stamps xrpl.branch / xrpl.node.role / xrpl.work.item with an empty-string
default (work_item | default('')) when a run has no work item, and an empty
string is not nil. OTTL Concat renders a stray separator for an empty element,
so an all-empty perf-iac stamp would have produced iac_group="--".
Add != "" to every presence guard (iac_group sources, service.instance.id,
xrpl.network.type) so a group is built only from genuinely-present values and
left unset otherwise. Verified on a live collector: empty-string perf-iac attrs
leave iac_group absent.

Add the transform/legendgroups processor (introduced on phase-7 for the local
config) to the dual-export grafanacloud collector config, and copy the two
group labels onto datapoint attributes in transform/cloudlabels.
The local Prometheus scrape promotes resource attributes to labels via
resource_to_telemetry_conversion, but Grafana Cloud's OTLP ingest does not, so
resource_group / iac_group must be copied onto datapoint attributes the same
way service_instance_id / deployment_environment / xrpl_network_type already
are. legendgroups runs before cloudlabels in both metrics pipelines so the
built resource attributes are available to copy; the copies are presence-guarded
so an absent group is not created as an empty datapoint label.
Verified on a live collector (debug exporter): a perf node emits datapoint
attributes resource_group and iac_group; a non-perf node emits resource_group
only, with iac_group correctly absent.

Apply the collector-built grouped-label legend approach (introduced on
phase-7) to the eleven dashboards this branch and its ancestors own:
consensus-health, fee-market, job-queue, ledger-operations, node-health,
peer-network, peer-quality, rpc-pathfinding, rpc-performance,
transaction-overview, validator-health.
Per legend panel: drop the 11-rule renameByRegex chain and legendFormat
"__auto"; set a Standard-option Display name referencing the pre-built
resource_group / iac_group labels plus, when the panel groups by a
distinguishing dimension (e.g. command, tx_type, consensus_mode, stage,
method), that dimension as a leading bracket; keep a single generic
empty-bracket cleanup rule; set tooltip maxHeight to 600.
Value-mapping renameByRegex rules (e.g. consensus close-time
increased->Coarser) are preserved. Only labels a panel groups by appear in
its legend; filter-only selectors ($command with no by(command)) narrow data
but do not become legend groups. All 14 dashboards validate; no legend
renameByRegex chain remains.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The per-panel legend used legendFormat "__auto" reshaped by an 11-rule
renameByRegex chain. __auto sorts labels alphabetically and cannot group,
so the chain existed only to bolt grouping onto its output -- unmaintainable
and non-compliant with the dashboard legend guideline.
Build the grouped labels once at ingestion instead. A new transform/legendgroups
processor derives two resource attributes, promoted to Prometheus labels by
resource_to_telemetry_conversion:
- resource_group: service_instance_id[-xrpl_network_type]
- iac_group: xrpl_branch-xrpl_node_role-xrpl_work_item (perf runs only)
Each is left unset when its sources are absent, so Prometheus drops the empty
label and the legend shows nothing for it. Concat is presence-guarded because
OTTL Concat renders "<nil>" for an absent attribute.
Dashboards now use a Standard-option Display name that references the pre-built
labels (${__field.labels.series} [resource_group] [iac_group]); ${__field.labels.X}
renders empty for a missing label, so absent groups vanish. A single generic
renameByRegex strips the resulting empty "[]" bracket. legendFormat is dropped
(Display name supersedes it). Tooltip maxHeight set to 600 per guideline.
Applied here to the three dashboards this branch introduced (ledger-data-sync,
network-traffic, overlay-traffic-detail); value-mapping renameByRegex rules are
preserved. Verified end-to-end on a live local stack (collector -> Prometheus ->
Grafana): perf and dev nodes render correct, clutter-free legends.

Panel legends only showed the node (service_instance_id); the perf-iac
filter dimensions (xrpl_branch, xrpl_node_role) never appeared, so
baseline-vs-test series were indistinguishable.
Each node-referencing target injects its curated name via
label_replace(...,"series",...) and uses the "__auto" legend, which shows
only labels that vary across the displayed series. A word-boundary-anchored
renameByRegex chain reshapes the auto output into
"Name [node, role]-[branch, work_item]", collapsing empty groups so a
dimension appears only when the filter widens it. Aggregating queries gain
xrpl_branch/xrpl_node_role in their by() so those labels survive; multi-
dimension legends keep their rich label set and append branch/role.
Quantile panels surface the quantile via the panel title (q$quantile),
since {{quantile}} is a dashboard variable, not a series label.
Timeseries panels connect only null gaps shorter than 30m
(spanNulls=1800000): brief scrape gaps bridge, genuine outages stay broken.
Non-node panels (heatmaps, rows, tables, state timelines, category/bucket
series) are left unchanged. Applied to all 14 dashboards.

Grafana Cloud variants of the 14 xrpld dashboards. Identical to the local
grafana/dashboards/ originals except the DS_PROMETHEUS / DS_TEMPO datasource
template variables have their `current` value pinned to the Grafana Cloud
datasource UIDs (grafanacloud-ripplex-prometheus / -traces).
Includes the ledger-data-sync data-type split and node-health mixed-unit
split + Cache Hit Ratio fix merged forward from phases 7 and 9.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The Cache Hit Ratio panel divided two nodestore_state series that carry
different `metric` label values (node_reads_hit / node_reads_total). Without
ignoring(metric) the two vectors share no common label set, so the division
matched nothing and the panel showed "No data".
Add `ignoring(metric)` to the division. Verified live against mainnet: now
returns a valid ratio (~0.11-0.23). Pre-existing bug, surfaced when the panel
was split out from NodeStore Read/Write Totals.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Three panels mixed incompatible units on one Y-axis (count vs ms, ops vs
percent), causing the small-magnitude series to flatline to zero.
- Last Close Info -> Last Close — Proposers (short) + Converge Time (ms)
- NodeStore Read/Write Totals -> Throughput (ops) + Cache Hit Ratio (%)
- NodeStore Read Threads & Duration -> Read Threads (short) + Busy Ratio (%)
Each new panel has a single unit; per-series unit overrides removed.

Span-derived metrics (span_calls_total, span_duration_milliseconds_*) were
emitted at the spanmetrics connector default of 60s. Grafana Cloud stores one
datapoint per flush, but dashboard panels use rate(...[$__rate_interval]),
whose window at short ranges (<=1h) falls below 60s — leaving <2 samples per
window, so those panels rendered "No data" on the Cloud datasource. (Local
Prometheus scrapes at 15s, so local dashboards were unaffected.)
Set metrics_flush_interval: 15s so every rate window holds >=2 samples at any
dashboard range. Trade-off: ~4x span-metric datapoints pushed to Cloud. Native
insight metrics (ledgermaster_*, jobq_*, peer_quality) already push faster and
were never affected.

Brings dashboard panel units, validator-health full-width layout, and filter
description polish into phase 10. The validator-health conflict was resolved
by keeping phase 10's per-target datasource uids and re-applying the unit,
layout, and description changes on top.
Document the three perf-iac filter template variables (xrpl_work_item,
xrpl_branch, xrpl_node_role) in the telemetry runbook and the data-collection
reference: what they filter, their example values, and that perf-iac stamps
them as resource attributes from its own alloy pipeline (absent outside
perf comparison runs, so the filters default to All). Also record perf as a
network value.

Set display units per panel so values render with correct scaling:
- counts/levels/depths → short
- per-minute rates (rate()*60) → cpm; genuine per-second → cps
- per-hour rate (rate()*3600) → suffix:/hr
- fee amounts → si:drops; UNL expiry → d (days)
Value-mapped and identity-number panels (server state, ledger seq, build
version) are left unitless so they are not abbreviated.
Lay out every validator-health panel at full width for readability.
Polish the shared filter descriptions (deployment tier, network values +
perf) across all eleven dashboards.

Brings the perf-iac dashboard filters (work item / branch / node role) into
phase 10. Conflicts in network-traffic and node-health were resolved by
keeping phase 10's query fixes (jobq_job_count rename; per-metric
label_replace identity for bytes-in breakdown) and re-applying the three
filter matchers on top.
Add three template variables (Work Item, Branch, Node Role) and their
label matchers to the remaining OTel dashboards so perf-iac comparison
runs can be filtered by ticket, comparison side (baseline/test), and node
role. The labels (xrpl_work_item, xrpl_branch, xrpl_node_role) are stamped
by perf-iac's alloy config as OTLP resource attributes and promoted to
Prometheus labels by Grafana Cloud; no repo collector change is needed.
Each variable mirrors the existing xrpl_network_type config (multi-select,
includeAll, allValue ".*") so local and non-perf runs — where these labels
are absent — continue to render (an absent PromQL label matches ".*").
Dashboards: consensus-health, ledger-operations, peer-network,
rpc-performance, transaction-overview, node-health, rpc-pathfinding,

Dashboard audit against the live datasource surfaced two broken panel queries
and applied UX polish across all 14 dashboards.
- node-health "Job Queue Depth": job_count -> jobq_job_count. The JobQueue
collector is wrapped in group("jobq") (Application.cpp), so the registered
job_count gauge is emitted with the jobq_ prefix; the panel queried the
unprefixed name and returned nothing.
- network-traffic "Overlay Traffic by Category" + "All Traffic Categories":
topk(N, rate({__name__=~".*_bytes_in"}[...])) errors on Mimir ("vector
cannot contain metrics with the same labelset") because rate() drops
__name__ and the many counters collapse. Replaced with an enumerated
label_replace form that re-attaches __name__ per metric, preserving the
{{__name__}} legend and per-series display-name overrides.
- All 14 dashboards: refresh set to 10s.
- peer-quality: each panel full screen width.
- validator-health: at most two panels per row (row headers preserved).
- docs: telemetry-runbook and 06-implementation-phases updated for the
jobq_ prefix and the network-traffic query pattern.
Verified end-to-end against a local mainnet xrpld node feeding the local
stack: jobq_job_count returns data (old job_count empty), both network-traffic
exprs execute (old form reproduces the labelset error), and panels render
through the Grafana proxy. All 14 pass validate_dashboards.py.

The phase-6 change replaced this piechart with the applied-ratio state
timeline, but phase-9's independently-diverged dashboard kept its own
copy (id 17) which survived the merge-forward. Its query filtered on the
$txq_status template variable, which was removed alongside the swap, so
the panel resolved to txq_status=~"" and rendered empty. Delete it so
only the state timeline remains.

Add an Alloy-based collector config as an alternative to the reference
OpenTelemetry Collector. It forwards xrpld OTLP traces and native metrics
to the Grafana Cloud OTLP gateway and, critically, runs a spanmetrics
connector so span-derived RED metrics (span_calls_total,
span_duration_milliseconds_*) are produced. Those metrics are not emitted
by xrpld; they are derived from spans, so an Alloy node without this
connector is missing from every span-based dashboard.
All credentials, endpoints, usernames and the per-node host label are read
from the environment (no secrets in the file). Adds a matching
.env.grafanacloud-alloy.example and gitignore exception, and the otelcol
term to the cspell dictionary.

Seed the $node template variable from target_info instead of a

The spanmetrics connector had no namespace, so it emitted traces_span_metrics_*
metric names by default. The span dashboards and docs are renamed to query
span_* names; this is only correct if the connector emits them too, so add
namespace: "span" to the spanmetrics connector. Both sides change together:
renaming the dashboards without the namespace (or vice versa) would break the
pipeline. Matches the phase9 collector config.

The phase7 OTelCollector::formatName lowercases and strips names, emitting
snake_case metrics with no xrpld_ prefix. The native Grafana dashboards and
the telemetry docs still queried the old xrpld_CamelCase names, so they were
broken against their own pipeline. Rename every metric name to match what the
code emits: drop the xrpld_ prefix and lowercase the remainder. The two job
histograms also drop the redundant 'duration' word (job_queued_us,
job_running_us) to match the phase9 forms. Add havetxset to the cspell
dictionary since the lowercased metric name no longer word-splits.

Continuation of the same default change applied on phase-6-statsd
(50d7047abe): the 5 dashboards introduced on phase-7 (formerly

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Change the pre-selected value of the service_name template variable from
'All' to 'xrpld'. On first load, dashboards now filter to service.name=xrpld
directly rather than showing every service the collector sees. The 'All'
option is still selectable — this only changes the default the widget
starts on.
Reduces the chance of a fresh dashboard link showing unrelated services
(e.g. non-xrpld exporters sharing the same Grafana Cloud stack) before
the user narrows the filter.

Grafana Cloud's OTLP ingest already promotes the `service.name` resource
attribute to a `service_name` metric label. The `transform/cloudlabels`
processor was ALSO setting `service_name` as a datapoint attribute,
which Mimir treats as a duplicate label and concatenates as
`service_name="xrpld;xrpld"` on every series. Dashboards filtering on
`service_name=xrpld` then returned no data.
Remove the redundant `set(attributes["service_name"], ...)` line and
add a comment documenting the doubling. `service.instance.id` does not
exhibit the same behaviour, so that copy is retained for the $node
filter to keep resolving.
Reintroduces the pre-e76eed5296 shape (which was correct on this label)
without reverting that commit's other cloud-label fixes.

These four dashboards were introduced on phase-9: peer-quality and
validator-health via b92354715d, fee-market and job-queue via 25868f2740.

ambiguous 'Service'.

Continuation of the same rename applied on phase-6-statsd (commit
91c6582bd5): 5 more dashboards introduced on phase-7 (formerly the
system-* set, renamed to bare names by 2c590a47c5) still carried the
older 'Service' UI label. Aligning them with the rest.
Same reasoning as the phase-6 commit: the underlying Prometheus label
is `service_name`, and the UI label 'Service' misled users into typing
`service=xrpld` in Grafana Metrics Drilldown.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
The template variable's Prometheus label name is `service_name` but the
UI display label read 'Service', which mismatched what users typed into
Grafana's Metrics Drilldown UI (which defaults to filter on a bare
`service` label). Rename the display label to 'Service Name' so it
unambiguously points at the underlying `service_name` Prometheus label.
Behaviour unchanged; template-variable name (`service_name`) and PromQL
label are the same. Only the widget label shown at the top of the
dashboard changes from 'Service' to 'Service Name'.

Remove redundant xrpld_ prefix from all 34 MetricsRegistry instrument
names — service identity comes from the OTel resource, not the metric
name. Duration histograms retain their unit suffix (job_queued_duration_us,
job_running_duration_us, rpc_method_duration_us).
Set spanmetrics connector namespace to "span" so derived metrics become
span_calls_total and span_duration_milliseconds_bucket instead of the
verbose traces_span_metrics_ prefix.
Update all 14 dashboard JSONs: strip xrpld_ prefix, lowercase
beast::insight metric names, replace traces_span_metrics_ with span_.

Add service_name to transform/cloudlabels so Grafana Cloud dashboards

Drop the xrpld_ prefix from beast::insight metric names — the OTel
resource (service.name=xrpld) already identifies the service. formatName()
now lowercases and sanitizes spaces/dots to underscores for
Prometheus-compatible names.
Also fix 4 source strings containing spaces that produced invalid OTel
instrument names (silently rejected by the SDK).

The workload validator queried each expected metric once, immediately after
a fixed post-workload propagation wait. Several beast::insight metrics
(ledger-age and peer-finder gauges, overlay-traffic and rpc-request counters)
only populate after the node validates ledgers and sustains peer traffic,
then travel a 1s OTLP export + 15s Prometheus scrape before they are
queryable. On a slower CI runner that pipeline can settle after the wait
ends, so the single query raced and reported "0 series", failing 12 checks
that pass locally with the same config and binary.
Poll each metric on the /api/v1/series endpoint until it appears or a 45s
window (two scrape cycles) elapses. Present metrics still return on the first
query with no added delay; a genuinely-absent metric still fails after the
timeout. Makes the check robust to runner speed.

xrpld resolves a relative [debug_logfile] against the config file's own
directory (docker/telemetry), not the working directory. The value
`docker/telemetry/data/logs/devnet/debug.log` therefore doubled the
prefix to docker/telemetry/docker/telemetry/... — the collector's mount
never saw the log, so no lines reached Loki.
Use the config-dir-relative form `data/logs/devnet/debug.log`, which
resolves to docker/telemetry/data/logs/devnet/debug.log — exactly the
dir the compose stack bind-mounts as /var/log/xrpld.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Extend the log-mount consolidation to the phase-10 workload-validation
assets, which still used the old `rippled` container path:
- docker-compose.workload.yaml: mount target renamed to /var/log/xrpld,
source made overridable via XRPLD_LOG_DIR (default /tmp/xrpld-validation)
- otel-collector-config.grafanacloud.yaml: single glob /var/log/xrpld/*/debug.log
- run-full-validation.sh sets XRPLD_LOG_DIR to its workdir
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The collector's log ingestion used a container path named after the old
`rippled` binary and defaulted its host mount to a location that either
needed root or diverged from where the telemetry configs actually write.
Consolidate on one accessible log root:
- container mount target renamed /var/log/rippled -> /var/log/xrpld
- filelog glob -> /var/log/xrpld/*/debug.log
- compose mount source defaults to the repo-relative ./data/logs
(user-owned, no root), overridable via XRPLD_LOG_DIR
- devnet telemetry cfg writes to data/logs/devnet/debug.log so it lands
one subdir below the mount root and matches the glob
- integration-test.sh sets XRPLD_LOG_DIR to its own workdir
- docs/runbook/task-list updated to match
The default xrpld config (cfg/xrpld-example.cfg) is intentionally left
untouched.

- PerfLogImp::rpcEnd(): return after the requestId-not-found UNREACHABLE
so a stale (now - epoch) duration is no longer recorded to the counter
and histogram in release builds.
- MetricsRegistry peer-version gauge: compare versions numerically via
BuildInfo::encodeSoftwareVersion() instead of a lexicographic string
compare, stripping the non-digit prefix so peer 'rippled-X.Y.Z' lines
up with our bare 'X.Y.Z'. Fixes every peer counting as higher-version.
- MetricsRegistry::stop(): call Shutdown() before ForceFlush() before
reset() so the reader thread stops before teardown and no gauge
callback fires during shutdown.
- MetricsRegistry::start(): extract initExporterAndProvider() and
initSyncInstruments() helpers to keep each function under the line
limit; no behavior change.
- time_in_current_state_seconds: read NetworkOPs::getServerStateDurationUs()
(a lightweight accessor over StateAccounting) and convert microseconds

- node-health.json: repoint the two "All Jobs" detail panels from the
__name__ regex over old xrpld_<job>_milliseconds_bucket names to the
native xrpld_job_running/queued_duration_us_bucket histograms, grouping
by the job_type label and legending on {{job_type}}.
- OTelCollector::callHooks: copy the hook list under mutex_ and invoke
handlers outside the lock. A handler can drop the last reference to an
OTelHookImpl, whose destructor calls removeHook() and re-acquires the
non-recursive mutex_ — invoking handlers under the lock could deadlock.
- ~OTelGaugeImpl: document that the SDK ObservableRegistry serializes
RemoveCallback against the Observe() callback pass with one mutex, so
callback removal is synchronous and gaugeCallback cannot run on a
dangling pointer after the destructor.

The Key Jobs execution/dequeue panels queried StatsD-era per-job metric
names (xrpld_<job>_milliseconds_bucket, xrpld_<job>_q_milliseconds_bucket)
that the native OTel path no longer emits. Phase 9's MetricsRegistry emits
job timings as two label-dimensioned histograms instead:
xrpld_job_running_duration_us_bucket{job_type="<job>"}
xrpld_job_queued_duration_us_bucket{job_type="<job>"}
Rewrite the 22 affected panel queries (11 job types x running/queued) to
the label-dimensioned form, preserving the histogram_quantile / rate /
sum-by structure and all template-variable filters.

- MetricsRegistry: service.name was recorded as boolean true because the
string literal "xrpld" bound to the OTel AttributeValue variant's
char-const* -> bool overload. Assign std::string so it selects the
string alternative; Prometheus now shows service_name=xrpld (and
exported_job round-trips correctly) on every MetricsRegistry series.
- Grafana alerting contact points: the Slack url / email addresses used
${ENV_VAR} references that expand to empty when unset, and Grafana's
provisioning validator (which lacks ${VAR:-default} support) then
crashes the whole stack on startup. Use non-empty disabled placeholders
(unroutable webhook host, .invalid email) so the stack boots with zero
configuration; delivery stays off until a real destination is supplied.

- ValidationTracker: remove dead hard-trim Pass 1. The preceding
eviction loop already erases every reconciled entry older than the
late-repair cutoff using the same condition, so Pass 1 could never
match. The "drop any reconciled entry" fallback is retained.
- integration-test.sh: probe the StatsD port with a UDP-aware check
(ss -ulnp) instead of curl. StatsD is UDP-only on 8125, so the TCP
curl probe always reported "refused" — a false negative. Guarded by
a command -v ss check that logs a skip when ss is unavailable.

Give developers direct access to the full OpenTelemetry metrics API,
symmetric with getTracer(), so all seven OTel instrument types
(including UpDownCounter, sync Gauge, and the observable variants) are
reachable — not just the four beast::insight models.
- Telemetry: build and own the metrics pipeline (OTLP HTTP metric
exporter + PeriodicExportingMetricReader + SpanMetrics histogram view)
alongside the tracer, sharing the same resource attributes and TLS
config. Register it globally via metrics::Provider::SetMeterProvider
and expose Telemetry::getMeter(). Metrics enable with [telemetry];
the metrics endpoint is derived from the trace endpoint.
- beast OTelCollector: no longer owns a pipeline. It fetches the global
Meter, becoming a thin shim over the shared provider (legacy path
during beast deprecation). This also resolves the review note that the
metric exporter ignored [telemetry] use_tls — TLS now comes from the
shared telemetry pipeline.
- Add a libxrpl unit test covering getMeter() on the enabled (global
provider) and disabled (noop) paths, exercising an UpDownCounter.

- cmake: keep the opentelemetry-cpp umbrella target for the beast metrics
link and document why. The reviewer suggested linking individual
component targets to avoid over-linking, but the OTel Conan package
under-declares inter-component dependencies (the OTLP client references
sdk::common symbols without a declared edge), so naming components
directly reorders the static link into an unresolvable state. Verified
by building xrpl_tests both ways.
- OTelCollector.h: add usage examples, thread-safety and limitations
@note blocks to the class doc.
- OTelCollector.cpp: correct the @param name docs on the instrument
Impl constructors to describe the already-formatName()'d value.

Replace the placeholder webhook contact point with two env-driven tiers:
- xrpld-default (Slack) receives warning-severity alerts
- xrpld-critical (Slack + email) receives critical-severity alerts, via a
severity=critical child route in the notification policy
Secrets stay out of git: contactpoints.yaml references ${SLACK_WEBHOOK_URL},
${SLACK_CHANNEL}, and ${ALERT_EMAIL_TO}, which Grafana expands from a
gitignored .env.alerting (loaded via an optional env_file on the grafana
service). .env.alerting.example documents the variables; email additionally
needs GF_SMTP_* configured.
Fold the ALERTING.md runbook content into the Alerting section of
docs/telemetry-runbook.md (operator docs live in one place) and delete
ALERTING.md. Move the .env.* ignore rule into docker/telemetry/.gitignore.

Soften the "non-reversible" wording in Redaction.h. XRP account
addresses are a public, enumerable set, so an unsalted hash is
obfuscation (keeps plaintext out of traces/dashboards), not a

it would break cross-node/restart correlation, the reason for
hashing rather than dropping the attribute.

Resolve the doCommand error-path span suffix and command attribute against
the handler registry instead of using raw request input. A recognized command
yields its canonical handler name; anything else (unregistered command, or
neither command/method present) collapses to the literal "unknown". This bounds
telemetry cardinality to the finite set of handler names plus "unknown" while
preserving per-command error attribution for known-but-rejected commands
(e.g. a submit that hit rpcTOO_BUSY stays rpc.command.submit). The command
attribute is promoted to a Prometheus label by the spanmetrics connector, so
attacker-controlled input previously enabled unbounded label cardinality.
Also add the missing LCOV_EXCL_STOP in the first SpanGuard::linkedSpan overload
so its coverage exclusion no longer bleeds into the second overload's guards.

Provisioned YAML under grafana/provisioning/alerting/ (auto-loaded by the

-> reduce(B, last) -> threshold(C) on the Prometheus datasource.
- contactpoints.yaml: xrpld-default webhook receiver (local-dev placeholder).
- policies.yaml: flat routing to xrpld-default, grouped by
alertname + exported_instance.

Filter dropdowns were empty on Grafana Cloud: template query-variables
referenced uid ${DS_PROMETHEUS} (a datasource variable that had no value
and was hidden), while panels used the bare default datasource. So panels
rendered but Service/Environment/Network/Node variables resolved against
nothing.
Wire DS_PROMETHEUS (and DS_TEMPO where used) through every panel, target,
annotation, and query-variable, and make the pickers visible. Empty
current value means each instance auto-selects its default datasource of
that type, so one dashboard set works on both the local stack and Grafana
Cloud without per-instance uids.

Grafana Cloud ingests metrics via OTLP with no Prometheus scrape, so the
tier/instance resource attributes never became series labels the way the
local prometheus exporter promotes them. Dashboard $node,
$deployment_environment, and $xrpl_network_type filters therefore matched
nothing on Cloud (only service_name existed).
Split the metrics pipeline: metrics/local keeps the Prometheus exporter
(unchanged label promotion), metrics/cloud adds a transform that copies
service.instance.id -> exported_instance, deployment.environment ->
deployment_environment, and xrpl.network.type -> xrpl_network_type onto
datapoint labels so the same dashboards filter correctly on both backends.

Fold the 7 panels from the separate RPC Performance (OTel) dashboard into
RPC Performance as a labelled 'Per-Method Detail' section, and retire the
duplicate dashboard. The two showed the same subject (RPC) from two data
sources; one dashboard with two sections is clearer and loses no panel.
Adds the $method template variable for per-method filtering.

The integration-test.sh trace queries used resource.service.name="rippled",
but the OTel resource attribute is "xrpld" (TelemetryConfig.cpp, MetricsRegistry.cpp),
so every span check and the service-registration check returned no results.
Also restore .github/scripts/rename/README.md, which an overzealous
find-and-replace had corrupted into circular no-ops (e.g. rename "xrpld" to
"xrpld"). The file documents the rename process and must retain the source
names (rippled/ripple); restored to match develop.

Add a Deployment Tiers section covering the four filtering dimensions
(node, service, network, environment), who owns each attribute, the
collector's upsert-vs-insert rule, per-tier collector values, and how the
tier labels reach metrics. This is the operator-facing home for the
deployment-tier feature.

- 05-configuration-reference: service_name now applies to metrics as well

- 07-observability-backends: document that collector enrichment includes
deployment-tier tagging (deployment.environment + fallback
xrpl.network.type) for filtering one Grafana stack by tier.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Apply the deployment-tier tagging to the Grafana Cloud dual-export config
so cloud data is filterable by tier just like the local stack:
- add the resource/tier processor (deployment.environment upsert,
xrpl.network.type insert) and run it on all three pipelines.
- enable resource_to_telemetry_conversion on the prometheus exporter and
add the tier keys to spanmetrics for the local scrape surface.
Add docker/telemetry/DEPLOYMENT_TIERS.md documenting the four filtering
dimensions, the upsert-vs-insert ownership rule, per-tier collector
values, and how the labels reach each signal.

Add $service_name, $deployment_environment, $xrpl_network_type template

Add resource/tier to the logs pipeline so log records carry the same
deployment.environment and xrpl.network.type attributes as traces and
metrics. This lets a single Grafana stack filter logs by tier alongside
the other signals. resource/logs still runs first to set service.name
and the job label; resource/tier then adds the tier attributes.

The native OTel metrics path hard-coded service.name="xrpld" and stamped
no network attribute, while traces stamped a configurable service.name
and xrpl.network.type. Metrics therefore could not be filtered by service
or network. Align the two paths:
- OTelCollector::New / OTelCollectorImp gain serviceName + networkType
params. service.name uses the configured value (default "xrpld" when
unset, preserving today's behavior); xrpl.network.type is stamped when
provided. The key is a string literal because beast/insight sits below
the telemetry module and cannot include its SpanNames const.
- CollectorManager reads service_name from [insight], falling back to the
[telemetry] value, and receives the network type from the caller.
- Application derives the network type once via the shared
telemetry::networkTypeFromId, now declared in Telemetry.h and moved out
of an anonymous namespace so the trace and metric paths reuse a single
0/1/2 -> mainnet/testnet/devnet mapping (no duplication).
Dashboards (5 system-* files): add $service_name, $deployment_environment,
$xrpl_network_type template variables and wire them into every panel query
that filters by $node.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Extend the deployment-tier tagging to the metrics path and expose it in
the dashboards so a single Grafana stack can be sliced by environment,
network, and service:
Collector (otel-collector-config.yaml):
- prometheus exporter: enable resource_to_telemetry_conversion so
resource attributes (deployment.environment, xrpl.network.type,
service.name, service.instance.id) become Prometheus labels.
- metrics pipeline: run resource/tier so statsd metrics are tagged too.
- spanmetrics: add the tier keys to the resource-metrics grouping key
so per-tier series stay grouped separately.
Dashboards (5 files):
- add $service_name, $deployment_environment, $xrpl_network_type
template variables, named to match their Prometheus labels.
- inject the matching label filters into every panel query that
already filters by $node.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Add a resource/tier processor so each collector stamps the deployment
tier onto the signals it forwards, enabling a single Grafana stack to
hold data from many collectors and filter by tier:
- deployment.environment (upsert): the collector is authoritative for
its environment (local/ci/test/prod).
- xrpl.network.type (insert): the xrpld node already stamps its own
chain, so the collector only fills this when absent, never
overwriting a node's real network.
Wired into the traces pipeline (the only pipeline on this branch);
later phases extend it to metrics and logs as those pipelines appear.

Apply the same width rule from the earlier transaction-overview fix to the
job-queue, rpc-perf-otel, and rpc-performance dashboards. Timeseries panels
whose legend is a right-side table need the horizontal room, so they go to
full width (w=24); each stacks onto its own row and panels below shift down.
Pie charts, heatmaps, and bottom-legend panels stay half width.

CI enabled more clang-tidy checks via the upstream merge:

Add an opt-in collector config + compose override that forward traces,

* refactor: Update RPM version scheme; remove auto-update script; service hardening
- **RPM version scheme**: pre-releases now use `~` in the `Version` field instead of the `0.<release>.<suffix>` `Release`-field hack. Matches Debian's `~` convention, so RPM and DEB version strings are symmetric. Requires rpm ≥ 4.10 (RHEL 9 ships 4.17).
Before/after for a pre-release build:
```
# before
xrpld-3.2.0-0.1.rc3+202606011647.d4cb68d5.el9.x86_64.rpm
# after (symmetric with DEB)
xrpld-3.2.0~rc2+202606010139.7679a310-1.el9.x86_64.rpm
xrpld_3.2.0~rc2+202606010139.7679a310-1_amd64.deb
```
- **Auto-update removed**: `update-xrpld`, `update-xrpld.service`, and `update-xrpld.timer` deleted. The `50-xrpld.preset` `disable` line for the timer is dropped too.
- **Service hardening** (two new `[Service]` directives in `xrpld.service`):
- `CapabilityBoundingSet=CAP_NET_BIND_SERVICE` — drops every Linux capability except `CAP_NET_BIND_SERVICE`, capping the privilege ceiling to least-privilege while still letting operators bind ports <1024 (e.g. WS/HTTPS on 443).
- `SystemCallArchitectures=native` — restricts the service to the native syscall ABI, blocking alternate-ABI (32-bit/x32) syscalls used to evade seccomp filtering.
- [ ] Build RPM from a pre-release version (e.g. `3.2.0-b1`) and confirm `rpm -qi` shows `Version: 3.2.0~b1`, `Release: 1`
- [ ] Confirm `3.2.0~b1` sorts before `3.2.0` via `rpmvercmp`
- [ ] Install package and confirm no `update-xrpld*` units appear in `systemctl list-unit-files`
- [ ] Confirm `systemctl show xrpld` reflects the new `CapabilityBoundingSet` and `SystemCallArchitectures`
* fix: Track tmpfiles-created directories in RPM %files as %ghost
The follows-from link attribute used the dotted xrpl.link.type form, which
is reserved for resource attributes. Span attributes use the <domain>_<field>
underscore form, so the key becomes link_type.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The Tempo datasource search filter used the stale dotted xrpl.consensus.ledger_id
tag, but the consensus.round span emits the bare consensus_ledger_id key
(ConsensusSpanNames.h). The dotted tag matched no spans and failed the Rule C
naming check. Align it with L1.
The TxQSpanNames.h span-hierarchy comment and the Phase 3 task-list attribute
table showed txq.accept.tx, but the constant emits txq.accept_tx
(op::acceptTx = "accept_tx"). Correct both.
- peer.validation.receive now asserts the shared bare ledger_hash /
full_validation keys (was the dotted xrpl.ledger.hash and validation_full);
PARITY_SPAN_ATTRS checks both on the peer span too.
- Fix a span-name drift: the per-transaction accept span is txq.accept_tx
(op::acceptTx = "accept_tx"), not txq.accept.tx — the old assertion never
matched and was silently skipped as optional.
- Drop the "intentionally dotted" notes; there is no dotted span attribute.
The peer.validation.receive span now records the ledger hash and full-validation
flag under the shared bare keys ledger_hash / full_validation (same keys the
consensus validation spans use), so there is no longer a dotted span attribute.
Remove the "only dotted span attribute" note and update the peer attribute table.
The peer.validation.receive span recorded the ledger hash under the dotted
xrpl.ledger.hash form — the only dotted span attribute, and inconsistent with
the bare ledger_hash the consensus validation spans use for the same value.
Make the base SpanNames.h ledgerHash bare (ledger_hash) and add the shared
fullValidation key, so the peer and consensus validation spans share one key
per concept (told apart by span name, not an emitter prefix). PeerSpanNames now
re-exports both from the base; the peer validation_full key folds into the
shared full_validation. The peer trust attrs (proposal_trusted /
validation_trusted) already follow the convention and are unchanged.
Make consensus span-attribute keys consistent with the peer spans that record
the same concepts, using ONE shared name per concept (told apart by span name),
not an emitter prefix:
- Add the shared ledger_hash and full_validation keys to the base SpanNames.h
(a ledger-object property and an is-full-validation flag, both shared with the
peer validation spans); consensus re-exports them via `using` instead of
defining local copies.
- trusted (bare) -> proposal_trusted on consensus.proposal.receive and
validation_trusted on consensus.validation.receive — the same message-type
qualification the peer.{proposal,validation}.receive spans use.
Also collapse a same-emitter duplicate: establishCounter_ was recorded under
both establish_counter and establish_count on two consensus spans; both now use
establish_count (the establishCounter span-name constant is removed; the
establishCounter_ member variable is unchanged).
The consensus.proposal.receive and consensus.validation.receive spans record
the trust flag under proposal_trusted / validation_trusted (shared with the
peer spans of the same message type), not a bare `trusted`. Update the span
reference table to match.
State the rules so they stay consistent across code, collector, Tempo,
dashboards, and docs:
- Per-span-unique field -> bare name (the span name carries the domain).
- Same concept on more than one span -> ONE shared key, reused verbatim and
distinguished by span name, never tagged with the emitting workflow
(e.g. ledger_hash, full_validation, proposal_trusted/validation_trusted).
Defined once in the base SpanNames.h and re-exported by each domain header.
- Collision qualifier <domain>_<field> only to separate DIFFERENT concepts that
share a word, or the OTel-reserved status key (rpc_status, consensus_state).
- Dotted xrpl.<...> is reserved for resource attributes (xrpl.network.*).
Updates CONTRIBUTING.md (permanent home) and OpenTelemetryPlan §2.3.3.
Rule A silently missed a dotted span attribute (xrpl.ledger.hash) because of
two interacting bugs:
1. attr_keys_from_header resolved each constant via a flat global symbol table
keyed by bare name, so a later header defining a same-named constant (e.g.
consensus attr::ledgerHash = "ledger_hash") clobbered the base header's
attr::ledgerHash = "xrpl.ledger.hash", erasing the real dotted key from L1.
Now each constant is resolved against its own header (the global table only
seeds seg::/join() cross-file references); using-re-exports still resolve
globally.
2. derive_dotted_resource_keys allowlisted any dotted key declared in the base
SpanNames.h. Now it allowlists only the keys actually passed to
Resource::Create() in Telemetry.cpp (semconv service.* + the attr:: constants
set there, e.g. xrpl.network.*). A dotted key declared in a header but never
set as a resource attr is a Rule-A violation.
Adds 4 regression tests (collision, using-re-export, allowlist scope, brace
matching). No allowlist exception is added — the check now catches the
violation so the offending code can be fixed.
Forward-merge the OTel naming-check Rule C/D fixes and the phase 2-9 chain.
Conflict resolutions:
- 02-design-decisions.md TxQ Attributes: take the convention-correct markdown
table (txq_* keys) over the stale planned-attrs code block.
- SpanGuardFactory.cpp: keep the explanatory comment for the literal attribute
keys in the libxrpl test.
Rule C was reading docker/telemetry/tempo.yaml (the Tempo server config), which
has no filter tags, so it always SKIPped — L3 was silently unenforced. The
trace-search filter tags actually live in the Grafana datasource provisioning
file (docker/telemetry/grafana/provisioning/datasources/tempo.yaml) as
search.filters[].{tag,scope}. Point Rule C there (server file as fallback),
pair each tag with its scope, validate only span-scope tags against L1 (resource/
intrinsic tags like service.*/name/status/duration are exempt), and strip the
TraceQL span. prefix.
On phase-9 this turns "SKIP: C" into "OK: C: 24 tempo span-filter tags all in
L1" — L3 is now genuinely guarded. Adds a RuleCTempo test class (4 cases:
span-tag-not-in-L1 flagged, span-tags-pass, resource/intrinsic ignored, skip
when datasource absent). 83 tests total.

Phase 9 surfaced two Rule D gaps (false positives, not data errors):
- TraceQL `span.<attr>` / `resource.<attr>` references: the bare attribute is
in L1, but the scope-prefixed form was flagged. Now strip the
span./resource./event./link/instrumentation_scope. prefix before the L1
lookup.
- Native OTel metric labels (e.g. `job_type`, `reason`) emitted by
MetricsRegistry are valid dashboard labels but are not span attributes. Add
an L6 source: parse `Add(.., {{"label", ...}})` instrument calls and accept
those label keys alongside L1 and builtins.
Verified against phase-9's real dashboards: 6 prior false positives -> 0.
79 tests (7 new for span-prefix stripping and metric-label extraction).

Bring phase-8 (log correlation) and the naming-check + BasicConfig fixes forward
into phase 9 (native-metrics gap fill). Phase 9 adds MetricsRegistry and
LedgerSpanNames.h.
Conflict resolution:
- presentation.md: took phase-9's restructured deck — sampling now lives in
Slide 8 (Head vs Tail) and the Phase 10/11/12 future-phase slides; phase-8's
older standalone sampling section is superseded (no content lost).
- ordering.txt/loops.txt: regenerated via generate.py.
Naming check: A/B/E/F/G green. Rule D reports 6 findings that are all check
gaps, not data errors (verified every dashboard label traces to code):
- 3 are TraceQL `span.<attr>` references (bare attr is in L1); Rule D should
strip the span./resource. scope prefix.
- 2 (`reason`, `job_type`) are native OTel metric labels emitted by
MetricsRegistry.cpp — a new source of truth the check does not yet model.
The Rule D enhancement lands on phase-1c and merges forward.

Bring native-metrics (phase 7) and the naming-check work forward into phase 8
(log correlation).
Conflict resolution — tempo.yaml datasource provisioning (search.filters):
- Took phase-7's complete 30-filter list as the base (it is the comprehensive
set), preserved phase-8's tracesToLogs Loki-correlation block, and added
phase-8's two unique filters (tx-type, ledger-hash). Verified the result is
the full union (32 filters) with no filter dropped and no duplicate ids.
- Fixed a pre-existing dotted tag carried in from phase-7: the
consensus-ledger-id filter used `xrpl.consensus.ledger_id`; the code emits
the underscore key `consensus_ledger_id` (ConsensusSpanNames.h), so the
dotted form was a dead filter. Now corrected.
Every span-scope filter tag verified to exist in the L1 *SpanNames.h key set.
Naming check green; 72 tests pass.

Rule D (dashboard PromQL labels must exist in L1) flagged `__name__` once the
phase-7 system-*.json dashboards started using `sum by (le, __name__)`.
`__name__` is the Prometheus reserved label for the metric name itself — a
builtin, not a span attribute. Add it to the builtin allowlist and cover it
with a test. (Earlier dashboards only used `__name__` inside `{__name__=~...}`
matchers, which the label regex did not extract, so this surfaced only now.)

Bring phase-4 forward into phase 5 (docs & deployment). Phase 5 owns the
operator runbook (docs/telemetry-runbook.md).
Conflict resolution:
- 05-configuration-reference.md: took phase-4's code-block-free prose for the
config-parser section; the mTLS options (tls_client_cert/tls_client_key)
remain documented in the §5.1.2 options table.
Phase-5-owned naming fix:
- docs/telemetry-runbook.md: converted 20 dotted xrpl.<domain>. attribute keys
in the Span Reference tables to the underscore convention (tx_hash, peer_id,
ledger_seq, consensus_mode/round/round_id/ledger_id, tx_id). Span NAMES stay
dotted (rule 5). `trusted` left as-is — verified it matches the code constant
ConsensusSpanNames.h (the proposal_trusted/validation_trusted split is a
separate, not-yet-applied code change).
End-to-end reconciliation: every span-attribute token in the runbook (L5) now
matches an L1 *SpanNames.h constant. The xrpl_<domain>_<field> tokens are the
spanmetrics-derived Prometheus labels (documented mapping), not span attrs.

Three entries in Phase4_taskList.md annotated dotted attribute keys
(`xrpl.consensus.round`, `round_id`, `ledger_id`) as "(kept — rule 5)". That
is wrong: rule 5 keeps SPAN NAMES dotted, not attribute keys — the code emits
the underscore form (consensus_round, consensus_round_id, consensus_ledger_id)
per ConsensusSpanNames.h. Remove the false justification; the dotted form in
this task list remains as the illustrative-readability form documented in the
note at the top of the file.

(consensus_round, ledger_seq, consensus_mode, consensus_round_id,
consensus_ledger_id, consensus_result, mode_old/new, agree_count/disagree_count,

Bring phase-3 forward into phase 4 (consensus tracing). Phase 4 introduces
ConsensusSpanNames.h (and already did the trusted→proposal/validation rename
and underscore-attr conversion in ffc197b914).
Conflict resolution (reviewed by a code-review agent before commit):
- 02-design-decisions.md §2.4 Consensus Attributes: merge-both — kept phase-3's
underscore table form AND folded in phase-4's richer "Phase 4a" attribute set
(round_id, ledger_id, trace_strategy, converge/establish/disputes counts,
agree/disagree counts, threshold_percent, consensus_result, mode_old/new),
each mapped to its authoritative ConsensusSpanNames.h constant. Dropped the
planned-but-unimplemented proposers_agreed/proposers_total (no code constant;
agree_count/disagree_count serve that role).
- SpanGuardFactory.cpp: kept phase-4's explanatory comment about why a libxrpl
test uses literal keys, plus the converted command/rpc_status keys.
Naming check passes (100 keys across 8 *SpanNames.h headers, including consensus).

Bring phase-2 forward into phase 3 (transaction tracing). Phase 3 introduces
TxSpanNames.h, TxQSpanNames.h, and TxApplySpanNames.h.
Conflict resolution:
- TxQ.cpp: kept phase-3's txq_span-based instrumentation (phase-2 had none).
Dropped the orphaned `NumberSO{... fixUniversalNumber}` line — develop's
#5962 (Retire fixUniversalNumber) removed that symbol repo-wide; the
conflict block had carried one stale copy that would not compile.
- 05/08/OpenTelemetryPlan.md: dropped the deleted 04-code-samples / POC_taskList
references (carried from phase-2), kept phase-3's new secure-OTel.md doc rows,
section, and Mermaid node/edge/style. Config code block -> prose; merged the
secure-OTel hardening pointer with the authoritative-config prose.
- Phase3_taskList.md: removed the "dotted keys for readability" note that came
from phase-2 — phase 3 already uses the underscore keys.
Reviewed by code-review agents: telemetry instrumentation intact, naming check
green (47 keys across 7 *SpanNames.h headers), no conflict markers.

The Phase3/4/5 task lists show attribute keys in the older dotted
`xrpl.<domain>.<field>` form because that mirrors how a fully qualified
attribute reads in a Tempo trace view, which keeps the planning prose readable.
Add a note to each clarifying that the implemented keys follow the underscore
convention in CONTRIBUTING.md and that the *SpanNames.h constants (enforced by
the CI naming check) are the single source of truth — so the dotted form here
is illustrative, not the literal key.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
SpanGuardFactory.cpp set dotted "xrpl.rpc.command"/"xrpl.rpc.status" attribute
keys. Test files are exempt from the naming check's Rule F (they pass arbitrary
literals to exercise the API), so this slipped through, but the keys should
still illustrate the underscore convention. Use "command"/"rpc_status".

Bring the hardened OTel naming check forward from phase-1c: unconditional
Rule F, test-file exemption, and the Rule H in-place-constant warning. The
check passes clean on phase 2 (24 keys across 4 *SpanNames.h headers including
PathFind; the SpanGuardFactory.cpp test is correctly exempt from Rule F).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Three robustness fixes to check_otel_naming.py, all on phase-1c where the
script lives:
- Rule F now runs UNCONDITIONALLY. It is a purely syntactic check on the
call-sites and does not need the L1 key set, so code that calls
SpanGuard::span/setAttribute directly without ever defining a *SpanNames.h
is still caught (previously it was silently skipped when no header existed).
- Exempt test files from Rule F (tests pass arbitrary literal keys to exercise
the API). The call-site matcher now requires a SpanGuard/`.`/`->` receiver,
so std::span and bare declarations no longer false-positive.
- Add Rule H (warning, non-fatal): a namespace-qualified constant used at a
telemetry call-site but not defined in any *SpanNames.h is flagged, catching
constants defined in-place instead of in the proper header. Bare locals and
std:: names are not warned to avoid noise.
SpanGuard.h / Telemetry.h @code examples updated to reference constants that
exist on this branch. README documents the new behavior.

The script and its README live on phase-1c (where check_otel_naming.py was
introduced). The test-file Rule-F exemption was mistakenly applied here on
phase-2; revert to phase-1c's version verbatim. The exemption and further
script improvements will land on phase-1c and merge forward, keeping the
script's logic on the branch that owns it.

Bring the naming convention, code-sample cleanup, and CI naming check into
phase 2 (RPC tracing). Phase 2 introduces PathFindSpanNames.h.
Conflict resolution:
- 04-code-samples.md, POC_taskList.md: deletion wins.
- 02-design-decisions.md: took the convention-applied tables, but kept phase-2's
accurate PathFinding summary row (pathfind_fast/search_level/num_paths/...,
matching the implemented PathFindSpanNames.h).
- 05/08: took the code-block-free prose; kept phase-2's Phase2-5_taskList.md
index rows (dropping only the deleted POC row). Fixed stale setup_Telemetry/
make_Telemetry doc references to the code-correct setupTelemetry/makeTelemetry.
- Telemetry.h auto-merged to the constant-based @code examples.
check_otel_naming.py change: exempt test files from Rule F (tests pass
arbitrary literal keys to exercise the API). The check passes clean on the
merged tree (24 keys across 4 *SpanNames.h headers, including PathFind).

Add Rule G to check_otel_naming.py: every span-attribute key must be
lower_snake_case (^[a-z][a-z0-9_]*$ per dot-separated segment). This catches
camelCase, UPPERCASE, and spaces in keys, which the structural (dotted) and
source (literal) rules did not. Document it in the script README and
CONTRIBUTING.md.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Add check_otel_naming.py and wire it into on-pr.yml so every PR validates
that span-attribute names stay consistent across the code, collector, Tempo,
dashboards, and docs.
- The valid key set is derived dynamically from the *SpanNames.h constants and
the resource attributes the code registers in Telemetry.cpp — no hardcoded
allowlist to drift.
- Each rule is presence-gated: it runs only when the file it needs is in the
tree, so the check is correct whether telemetry changes land in one PR or
several (the collector/Tempo/dashboard/runbook layers arrive in later phases).
- Rule A flags dotted span-attribute keys; Rule F flags string-literal
attribute keys and span-name arguments (values may be runtime data).
- stdlib-only, mirroring the levelization check (bare `python`, no pip step).
- Telemetry.h / SpanGuard.h @code examples now use *SpanNames.h constants so
the strict literal check passes.
- CONTRIBUTING.md documents the check and how to run it locally.

Bring the phase-1a/1b naming-convention and code-sample cleanup into 1c.
Conflict resolution:
- 04-code-samples.md, POC_taskList.md: deletion wins.
- OpenTelemetryPlan docs (01/02/03/05): took the convention-applied,
code-block-free versions; verified no attribute category, table row, or
section header was lost (the differences were dotted->underscore renames).
- Telemetry.h: kept 1c's RpcSpanNames.h constant-based example
(rpc_span::attr::command) over the string literal.
- 31 non-telemetry files are clean develop carry-forward (identical to 1b).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Bring the phase-1a code-sample cleanup into phase-1b.
Phase 1a deleted the two code-sample docs (04-code-samples.md,
POC_taskList.md) and stripped C++/config code blocks from the remaining
plan docs, replacing them with prose summaries and pointers to the real
source/config files.
Conflict resolution:
- 04-code-samples.md, POC_taskList.md: deletion wins (phase-1b's SpanGuard
rewrites of these files are intentionally dropped).
- 03/05/OpenTelemetryPlan.md: took phase-1a's code-block-free prose, but
kept phase-1b's accurate descriptions of the real telemetry code
(DiscardFlag.h, FilteringSpanProcessor, SpanGuard factory methods, and
the corrected file-count/file-list tables).
- presentation.md left untouched.

Bring the span attribute naming convention (phase 1a) into phase 1b.
Conflict resolution kept phase-1b's SpanGuard-based workflow and applied
the underscore naming convention to all non-code-sample text:
- Converted prose, tables, Mermaid labels, and TraceQL/PromQL query
references across the plan docs to the underscore form.
- Converted the two @code attribute-key examples in Telemetry.h
(command, tx_type).
- Left the code-sample files (04-code-samples.md, POC_taskList.md) and
03-implementation-strategy.md code blocks at the phase-1b version; the
code-sample docs are slated for removal on phase-1a.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Establish the single, authoritative naming convention for OpenTelemetry
span attribute keys so the code, collector, Tempo, dashboards, and docs
stay in sync.
- CONTRIBUTING.md: new "Telemetry span attribute naming" section under
the Style guide as the permanent, canonical home for the rules.
- OpenTelemetryPlan/02-design-decisions.md: new section 2.3.3 stating the
decided convention as design, and section 2.4 attribute schema realigned
to the underscore form (exact key spelling defers to the *SpanNames.h
constants).
- Sweep the remaining plan docs: convert dotted xrpl.<domain>.<field> span
attribute keys to the underscore form; leave span names and the
OTel-standard service.*/http.* and xrpl.network.* resource keys dotted.

The xrpl_tests target links only xrpl.libxrpl and cannot include the
xrpld-level ConsensusSpanNames.h / RpcSpanNames.h (CI build failure on
ubuntu-gcc-debug-arm64). Revert the test to underscore-form attribute
literals, restore the SpanNames.h include for seg::consensus, and drop
the now-unused tests.libxrpl -> xrpld.* levelization entries.

- tempo.yaml: align consensus filter tags with emitted keys
(consensus_mode, consensus_round, ledger_seq) instead of dotted form
- haveConsensus(): set span attributes before early-return paths so the
consensus.check span carries diagnostics even when consensus is not reached
- replace hardcoded consensus phase/result/vote literals with
ConsensusSpanNames.h val constants; add val::phaseOpen/Establish/Accepted
- ConsensusReceiveTracing.h: use canonical consensus::span constants instead
of duplicate inline detail:: names
- SpanGuardFactory test: use rpc_span / consensus::span constants now that
levelization permits the dependency

BasicConfig.h moved from xrpl/basics/ to xrpl/config/ on develop

Document that head sampling is intentionally fixed at 100% and no longer
exposes a sampling_ratio config knob. A per-node ratio let nodes make
divergent keep/drop decisions for the same distributed trace, producing

Flip the tracePeer Setup default and the trace_peer config parser
default from off to on, and update the example config and build doc to

id) plus trust/ledger metadata — no IP addresses or public keys — so
the privacy concern behind disabling it does not apply. The high-volume
characteristic is retained in the docs.

Flip trace_peer default false->true across the Phase-1a plan docs and

The txq.enqueue span sets tx_hash, tx_type, and txq_status on every
code path (TxQ.cpp:746/748/751), but fee_level_paid and
required_fee_level are set only on the fee-evaluated path
(TxQ.cpp:895-898), which is reached after the rejected and
applied_direct early exits. They are therefore not guaranteed on every
txq.enqueue span, so requiring them caused the validation harness to
fail whenever a txq.enqueue span took an early-exit path.
Remove the two conditional attributes from required_attributes and
document why in the span note.

Several close-time panels showed raw codes/booleans and unreadable
time-bar-charts. Relabel and re-visualize them so each reads clearly:
- Close-Time Proposal Spread (was "Close Time Bin Distribution"):
corrected a wrong description (it claimed per-node proposals; the
metric is the number of DISTINCT close-time positions peers proposed
per round, rawCloseTimes.peers.size()). Converted the time-barchart
(unreadable timestamp axis) to a horizontal bar gauge summing rounds
per distinct-position count.
- Consensus Outcome Distribution: renameByRegex maps the raw
consensus_state codes to human labels (yes->Agreed,
moved_on->Moved On (partial), expired->Expired (timeout), no->No
Consensus); value mappings alone do not relabel pie legends.
- Close-Time Agreement Rate (was "Close Time Agreement"): legend
relabelled from "close_time_correct=true/false" to Agreed/Disagreed.
- Close-Time Resolution Change (was "Close Time Resolution Direction"):
converted to a bar gauge; increased/decreased/unchanged relabelled to
Coarser (more disagreement) / Finer (better agreement) / Steady.
All four verified by rendering the panels to PNG via the Grafana
image renderer.

"Close Time: Raw Proposals" and "Close Time: Effective / Quantized"
plotted the absolute close time (Ripple-epoch seconds), which is an
ever-rising line with no analytical value. There is no clean way to make
them useful: the values are Ripple-epoch seconds (not Unix ms, so date
units misrender), TraceQL metrics cannot do the epoch offset or an
inter-ledger-gap subtraction in-query, and Grafana calculateField
transforms break on these grouped Tempo metric frames (verified by
render: "No data").
Remove both. The useful consensus-timing signals are already covered:
time-to-consensus (round_time_ms), rounds per ledger (establish_count),
previous round time, and the close-time vote-bins / resolution-direction
/ bin-distribution panels remain. Re-tile and re-id (22 panels).

With validation now passing 133/133, the only remaining job failure was the
regression gate flagging 4 timing "regressions". Two compounding causes:
1. Stale baseline: the committed baseline was captured (2026-04-24) under the
old, lighter workload — before the new txq-burst phase (60 TPS) existed. The
heavier per-ledger work genuinely raises ledger.build / tx.apply /
ledger.validate / acceptLedger timings, so every run regressed against it.
Refreshed the baseline from the latest CI-measured timings (same workload).
2. Histogram quantization: SpanMetrics latency buckets are
[1,5,10,25,...]ms, so a sub-millisecond quantile near a low-end boundary can
jump a full bucket (1ms->5ms) between runs with no real change. The old
absolute bounds (2-5ms) were narrower than one bucket width, so that jitter
tripped the gate. Widened the default span bounds to 10-15ms (~2 low-end
buckets) and pct to 50%, and the job_queue running bound to 20ms, to tolerate
quantization noise while still catching genuine multi-bucket regressions. The
consensus.* overrides (tight pct, large abs) are unchanged.
The refreshed baseline also picks up real rpc.ws_message timings (previously null
under the phantom rpc.request key).

Number of rounds is an integer, but avg_over_time(establish_count)
produced fractional values (2.1). Switch the Rounds panel to
count_over_time() by (span.establish_count): one integer series per
round count (1/2/3...), showing how many ledgers needed that many
establish rounds — the meaningful distribution, inherently integer
(decimals=0).
Apply dashboard rule 9: panels with a right-side table legend take full
width. Widen "Consensus Rounds per Ledger" and "Consensus Outcome
Distribution" to w=24 and re-tile the dashboard.
Verified via the Grafana proxy: rounds=2 dominates (~11-12 ledgers),
rounds=3 occasional.

Phase 9 introduces the ledger.acquire span (InboundLedger fetch) that phases 7-8
do not have, so the forward-merged 09-data-collection-reference inventory is
extended here:
- §1.1: add ledger.acquire to the Ledger span table.
- §1.2: add its attributes (acquire_reason, timeouts, peer_count, outcome) and
note it also sets ledger_seq; bump the span count.
Also fix two stale StatsD metric references in the Peer Quality dashboard
(xrpld-peer-quality.json): rippled_Peer_Finder_Active_{Inbound,Outbound}_Peers
-> xrpld_Peer_Finder_* to match the xrpld_ metric prefix the rest of the stack uses.

The consensus duration panels plotted span wall-clock
(traces_span_metrics_duration_milliseconds), which is ~3-8 ms of
instrumentation overhead, not the real consensus time (~3000 ms). And
the close-time value panels plotted an ever-rising absolute epoch line.
Rework them to answer the actual operational questions, all from
attributes that already exist on the consensus spans:
- Time to Reach Consensus (p50/p95) and Average Time to Reach Consensus:
round_time_ms on consensus.accept — the wall-clock to agree a ledger.
- Consensus Rounds per Ledger (Establish Count): avg and max of
establish_count on consensus.establish — how many proposal rounds it
took to converge (1 = first proposal).
- Previous Round Time per Ledger: previous_round_time_ms on
consensus.round.
Reorder the dashboard into an investigation flow: health/throughput ->
time-to-consensus and rounds -> ledger close/apply timing -> close-time
detail -> failures/mode/mismatch. Assign stable sequential panel ids.
Verified each query returns data via the Grafana datasource proxy
(p95 ~4096 ms, avg ~2825 ms, rounds ~2).

The §1 span and attribute inventory had regressed to an older 16-span snapshot
that uses the pre-2026-05-13 dotted attribute keys, while phase-7's code emits
~36 spans with bare/underscore attribute keys. The §Data Flow Overview and §2
System Metrics sections (native OTLP transport — phase-7's migration) were already
correct and are left unchanged.
- §1.1: expand the span inventory to the full surface — add gRPC (grpc.<MethodName>),
TxQ (txq.*), PathFind (pathfind.*), and the full consensus set (round/phase.open/
establish/update_positions/check/mode_change/proposal.receive/validation.receive).
Fix the phantom rpc.request -> rpc.http_request, add rpc.ws_upgrade. No grpc.request,
no pathfind.rank, no ledger.acquire (the latter is added in phase-9, not yet present here).
- §1.2: convert every span-attribute key from dotted xrpl.<domain>.<field> to the
bare/underscore form. The sole span-attr dotted exception is xrpl.ledger.hash on
peer.validation.receive (shared constant); consensus.validation.send uses bare
ledger_hash. Resource attrs xrpl.network.id/type stay dotted. Fix tx_count/tx_failed
placement (on tx.apply, not ledger.build). Add attribute tables for the new families.
- §1.3: list the full set of spanmetrics dimension labels (bare keys, from the collector
config) instead of the stale xrpl_rpc_command-style names.
- §4/§5: convert Tempo TraceQL and PromQL examples to the bare attribute/label forms.

The print-env CI fix let the Telemetry Stack Validation job build and run the
workload harness end-to-end for the first time. It reported 129/136 checks
passing; this commit fixes the 7 real failures plus a latent regression-gate bug.
Validation-suite fixes (verified against the CI run's actual emission + live node):
- expected_metrics.json: the beast::insight job-depth gauge is `xrpld_jobq_job_count`,
not `xrpld_job_count` (the latter is a Phase 9 OTel counter). Reverted the prior
rename. Removed the statsd_histograms block (`xrpld_rpc_time`/`xrpld_rpc_size`):
these RPC timers do not emit under the WS workload (0 series in CI).
- expected_spans.json: `tx_status` is only set on suppressed/known-bad receives, so
it is no longer a required attribute of every `tx.receive`. Marked `pathfind.compute`
and `pathfind.discover` optional and the `pathfind.request -> pathfind.compute`
hierarchy as skip — the self-to-self XRP probe returns before computing paths in a
fresh cluster with no liquidity, so only `pathfind.request` fires.
Regression-gate bug (telemetry-validation.yml "Print regression summary"):
- `jq -e` exits non-zero when its filter result is boolean false — the normal case
for a populated (non-placeholder) baseline — which was misreported as
"Failed to parse baseline JSON" and failed the job. Dropped `-e` (kept `-r`) so a
non-zero exit genuinely means malformed JSON.
The optional-span handling and regression comparison both worked correctly in the
CI run (txq.* / pathfind.update_all skipped-when-absent, 0 regressions detected).

Apply the dashboard guidelines to the five close-time panels:
- Axis labels (Title Case) on every panel: "Close Time (Ripple
Seconds)" for the value panels, "Count / Milliseconds" for vote
bins/resolution, "Rounds in Window" for the count panels.
- Human-readable legends with the dimension in brackets per the legend
convention: "Raw Close Time [{{resource.service.instance.id}}]",
"Effective Close Time [...]", "Resolution Direction
[{{span.resolution_direction}}]", "{{span.close_time_vote_bins}} Vote
Bins" — replacing the bare label tokens.
- Unit "none" (plain number): the close-time values are Ripple-epoch
seconds and TraceQL metrics cannot offset them to a wall-clock unit,
and the others are counts/ms on a shared axis.
Verified rendered values against raw spans: close times ~833,998,8xx,
resolution 10000 ms, vote bins 1/2/3 — all correct.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
TraceQL metrics queries default to a 3h max range
(query_frontend.metrics.max_duration), so a dashboard set to a longer
window failed with "range ... exceeds 3h0m0s". Add a query_frontend
block raising it to 168h, matching the search max_duration, so the
consensus close-time panels work at 6h/12h/24h ranges.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The Raw Proposals and Effective/Quantized panels rendered nameless
series: their legendFormat used {{service.instance.id}}, but the
TraceQL metrics query groups by resource.service.instance.id and Tempo
returns that full key as the series label. The legend token did not
match any label, so each series showed blank. Use the matching
{{resource.service.instance.id}} token.
Verified via the Grafana datasource proxy that all six close-time panels
now return correctly-labelled series.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The Raw Proposals and Effective/Quantized panels showed wrong values
(e.g. 759M, 852M, even 0) against a true value of ~834M. Cause:
quantile_over_time bucketizes into an exponential histogram tuned for
duration distributions, so it cannot represent large absolute integers
(Ripple-epoch seconds) accurately.
Switch both panels to avg_over_time, which returns the correct value
(verified ~833,996,7xx matching the raw span attribute). Average is also
the semantically right aggregation here: close time is a single agreed
value per consensus round, not a latency distribution, so a median was
never meaningful.
Set the unit to none rather than seconds: the value is Ripple-epoch
seconds (Unix = value + 946684800) and TraceQL metrics cannot do the
offset arithmetic in-query, so a duration unit would misrender it.
Clarify in the description that the absolute level tracks wall-clock and
the useful signal is per-node spread / raw-vs-effective gap.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The five Close Time panels still rendered "No Data" after the metrics
rewrite. Root cause: each query carried
`span.close_time_correct=~"$close_time_correct"`, but close_time_correct
is a boolean span attribute and TraceQL's regex match (=~) against a
bool matches nothing in a metrics query, so every panel returned an
empty series set (HTTP 200, {"series":[]}).
Remove that filter clause. The panels do not break down by
close_time_correct, so dropping it restores data without losing any
dimension. The $node filter (a string attribute) is unaffected and
stays.
Verified via the Grafana datasource proxy that all six targets now
return series.

Wire the two previously-registered-but-never-incremented validation
counters to ValidationTracker's gross lifetime tallies, exported as
monotonic ObservableCounters. New gross atomics count each ledger once at
first classification and are never adjusted on late repair, keeping the
_total counters monotonic and additive (agreements_total + missed_total ==
ledgers reconciled); the repair-aware windowed view stays on the existing
xrpld_validation_agreement gauge. The validator-health dashboard panels
that already query these names now render data instead of "No data".
Also de-stale 09-data-collection-reference.md: §5b documented flat metric
names (xrpld_cache_SLE_hit_rate, ...) that the code never emits — it emits
labeled gauges (xrpld_cache_metrics{metric="SLE_hit_rate"}). Replace the
stale flat-name tables with a pointer to the canonical labeled section,
reconcile the contradictory headline counts, and correct xrpld_job_count
to its real exported name xrpld_jobq_job_count.
Adds two GTests asserting gross tallies stay frozen on repair while net
totals move, plus the additive invariant.

The Phase 10 validation harness had drifted from the code's recording surface
and the telemetry-validation CI job was failing before it could build.
CI fix (telemetry-validation.yml):
- Replace nonexistent local action ./.github/actions/print-env with the remote
XRPLF/actions/print-build-env (the build-xrpld job failed in 56s on this).
- Sync prepare-runner and upload-artifact action SHAs to the canonical workflow.
Recording-surface reconciliation (docker/telemetry/workload/):
- Migrate span attributes from dotted xrpl.<domain>.<field> to the bare/underscore
form introduced by the 2026-05-13 span-attr naming redesign (tx_hash, peer_id,
ledger_seq, consensus_mode, consensus_round, full_validation, quorum, ...).
Dotted xrpl.ledger.hash is retained only on peer.validation.receive (shared
constant), while consensus.validation.send uses bare ledger_hash.
- Fix attribute placement: tx.apply carries tx_count/tx_failed (not ledger_seq);
ledger.build carries ledger_seq/close_* (not tx_count/tx_failed).
- Replace the phantom rpc.request span with the real WS root rpc.ws_message; drop
the never-emitted duration_ms; rebuild the parent-child map accordingly.
- Add the new spans the code emits: apply-pipeline stage spans
(tx.preflight/preclaim/transactor with stage/tx_type/ter_result), txq.*,
consensus sub-spans (round/establish/update_positions/check/phase.open),
ledger.acquire, grpc.*, pathfind.*. Conditional spans are marked optional so
they are skipped (not failed) when the workload does not exercise them.
- validate_telemetry.py: service.name and Loki job label rippled -> xrpld; fix
PARITY_SPAN_ATTRS (rename the 4 real attrs, drop the 3 that are metrics not span
attrs); add optional-span handling that skips missing optional spans while still
validating attributes when present.
- expected_metrics.json: rippled_ -> xrpld_ on all beast::insight/overlay metrics,
xrpld_job_count, the 15 on-disk xrpld-* dashboard UIDs, and the real bare
spanmetrics dimension labels.
- regression-metrics.json + baseline-timings.json: rpc.request -> rpc.ws_message.
Metrics pipeline fix:
- Switch node [insight] config from server=statsd/prefix=rippled to server=otel +
/v1/metrics endpoint + prefix=xrpld across run-full-validation.sh,
xrpld-validator.cfg.template, benchmark.sh and the workload compose. The
collector has no StatsD receiver, so system metrics only reach Prometheus over
OTLP.
Synthetic load for new spans:
- Add ripple_path_find to the RPC load generator (drives pathfind.* spans).

All facts verified against the *SpanNames.h headers and a live xrpld node +

The five Close Time panels (Raw Proposals, Effective/Quantized, Vote
Bins & Resolution, Resolution Direction, Bin Distribution) rendered
empty: they used TraceQL `| select(attr)`, which returns a trace list
that a timeseries/barchart panel cannot plot.
Enable TraceQL metrics in Tempo and rewrite the panels to use it:
- tempo.yaml: add the local-blocks processor to the metrics generator so
recent blocks are queryable via /api/metrics/query_range. Set
filter_server_spans=false because the consensus spans are
SPAN_KIND_INTERNAL (the default keeps only server spans, so attribute
aggregations over internal spans returned nothing), and
flush_to_storage=true with a traces_storage path so query_range can
read the flushed blocks.
- consensus-health.json: replace each panel's select() with a metrics
query — quantile_over_time on the integer close-time attributes,
avg_over_time for vote bins / resolution, and count_over_time by the
resolution_direction and vote-bin dimensions. Set the raw/effective
panels' unit to seconds (the values are Ripple-epoch seconds, which
dateTimeFromNow rendered with the wrong epoch).
Verified the query forms compile and return series against live internal
spans; the close-time series populate once the node reaches full sync.

The Current Job Latency gauge sat at the bottom of the Job Queue
Analysis dashboard; per the dashboard guideline gauges belong at the
top. Move it to the first row and reflow the remaining panels below it.

Correct the width rule from the previous layout commit. Full width
(w=24) is now applied ONLY to timeseries panels whose legend is a
right-side table, since those legends need the horizontal room. Panels
with default/bottom legends, pie charts, and the heatmap return to half
width. This narrows "Transaction Receive vs Suppressed" and "TxQ
Enqueue Rate by Transaction Type", which were wrongly widened.

Make transaction-overview deep-links stable and improve readability:
- Assign explicit sequential panel ids (1..20) so viewPanel=panel-N
URLs stay pinned to the same chart across edits. Previously ids were
unset and Grafana auto-assigned them by array position, so any
reorder silently repointed bookmarks.
- Move the single-value stat panel (Transaction Apply Failed Rate) to
the top row.
- Lay out in three topic sections (Processing, Apply Pipeline, Queue).
Within each, timeseries with a breakdown dimension (tx_type, stage,
ter_result, suppressed) take full width so their right-side table
legends are readable; single-series panels, pie charts, and the
heatmap stay half-width and pair up.
All six template variables already default to All (includeAll + multi);
no change needed there.

Apply the dashboard legend convention across all panels now that the
P50 series have been removed (P95-only):
- Drop the redundant "P95 " / "P50 " prefix; the panel title already
states the percentile.
- Put every filter/dimension value inside [] comma-separated, ending
with exported_instance, e.g. "AMMDeposit [Preclaim, xrpld-mainnet]".
- Add exported_instance to the by() clause and legend of the three
panels that filtered on $node but omitted it (Transaction Rate by
Type, Transaction Results by Type, TxQ Accept Status), so per-node
series are produced.
- Title-case the stage value for display via label_replace in the four
apply-pipeline panels; the span attribute stays lowercase
(preflight/preclaim/apply) since legendFormat cannot change case.
- Cap tooltip maxHeight at 500 on every panel.

The existing apply-pipeline panels show latency by stage (all types
combined) or by type (single span). Neither answers "for a given
transaction type, which stage dominates its latency". Add a p95 panel
grouped by both tx_type and stage, filterable via the $tx_type and
$stage variables. Both dimensions already exist in spanmetrics, so no
collector change is needed. Reflow the section so the full-width
failure panel sits below the new full-width panel.

Wire the apply-pipeline stage spans (tx.preflight, tx.preclaim,
tx.transactor) added on phase-3 through the observability stack so the
spanmetrics connector produces per-stage RED metrics without any native
instruments.
- collector: add the `stage` dimension to the spanmetrics connector so
the three stages split into separate metric series (3 bounded values).
- dashboard: add a "Tx Apply Pipeline" section to transaction-overview
with rate, p95 latency, and failure-rate panels grouped by stage, plus
a `stage` template variable. Panels follow the existing config (node
filter, exported_instance legends, Title Case, axis labels).
- The failure panel filters ter_result != tesSUCCESS rather than span
status, because a failing ter code completes the span normally — only
thrown exceptions set an error status. This matches the existing
"Transaction Results by Type" panel convention.
- docs: document the spans, attributes, and stage dimension in the data
collection reference and runbook, including the sampling caveat that
span-derived metrics inherit tracer head-sampling and undercount at
sampling_ratio < 1.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The tx.transactor span covered only the apply stage; preflight and
preclaim had no telemetry, so a transaction that hard-failed those
stages produced no apply-pipeline span and per-stage latency/failure
was invisible.
Add tx.preflight and tx.preclaim spans in applySteps.cpp via a
makeStageSpan() helper using SpanGuard::hashSpan, so all three stages
share a deterministic trace_id derived from txID[0:16] even though they
run sequentially and often cross-thread. Each span carries stage,
tx_type, and ter_result; exceptions are recorded as tefEXCEPTION before
the public wrappers map them. The type lookup is guarded behind the
span-active check so it costs nothing when tracing is off.
Add a stage="apply" attribute to the tx.transactor span and move its
three hardcoded attribute strings to a new library-safe header
include/xrpl/tx/detail/TxApplySpanNames.h, which mirrors the daemon-side
TxSpanNames.h strings so the collector spanmetrics connector aggregates
both span sets under one dimension set.
A constants-contract test pins the span-name, attribute-key, and
stage-value strings; span content stays covered by the docker
integration test, as the rest of the telemetry suite is.

From the code-review pass:
- transaction-overview.json: the tx.process and tx.transactor latency-by-type
panels used lowercase legends (p95/p50) without the per-node dimension. Use
Title Case (P95/P50), add exported_instance to the by() clause, and include
[{{exported_instance}}] in the legend, per the dashboard legend convention.
- consensus-health.json: panel descriptions still referenced the old dotted
attribute names (xrpl.consensus.mode, xrpl.ledger.seq) after the A1 rename;
update them to the bare emitted names (consensus_mode, ledger_seq).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
handleMismatch() recorded the "consensus_txset" reason but then fell through
to the transaction-level comparison, which also recorded a reason
("same_txset_diff_result" / "different_txset"). A single mismatch with
disagreeing consensus tx-set hashes therefore incremented
xrpld_ledger_history_mismatch_total twice across two reason labels, so the
sum over reason exceeded the real mismatch count.
The consensus tx-set hash disagreement is the root cause; return after
recording it so each mismatch contributes exactly one reason.

The A1 fix (xrpl_consensus_mode -> consensus_mode) was applied on phase-6, but
the phase-8->phase-9 merge conflict resolution for consensus-health.json took
phase-9's pre-fix panel base, silently reintroducing all 11 stale
xrpl_consensus_mode label references (the spanmetrics label that is never
populated — see the original A1 commit).
Re-apply the label fix on phase-9: xrpl_consensus_mode -> consensus_mode in
every panel expr, legendFormat, and the $consensus_mode template variable's
label_values() query. The Grafana variable name $consensus_mode is unchanged.

Visualise the metrics added in this series:
- consensus-health: "Ledger History Mismatch Rate by Reason"
(xrpld_ledger_history_mismatch_total by reason — fork diagnostics)
- fee-market: "Queue Abandonment Rate (Expired)" and "Queue Admission
Rejections (Dropped)" (xrpld_txq_expired_total / dropped_total)
- peer-network: "Reduce-Relay Peer Selection" and "Reduce-Relay Missing-Tx
Frequency" (xrpld_reduce_relay_metrics)
- system-node-health: "Ledger Acquire Duration" and "Ledger Acquire Rate by
Outcome" (ledger.acquire span)
otel-collector-config.yaml: add outcome and acquire_reason spanmetrics
dimensions so the ledger.acquire outcome breakdown populates.
All panels follow the existing template: $node filter, exported_instance in

Add the new synchronous counters (ledger_history_mismatch_total{reason},
txq_expired_total, txq_dropped_total{reason}) and the reduce-relay observable

The transaction reduce-relay subsystem (selected vs suppressed peers,
feature-disabled peers, missing-tx frequency) was computed in OverlayImpl's
TxMetrics but only surfaced via the get_counts JSON RPC — invisible to
Prometheus/Grafana, despite being the central efficiency KPI for the feature.
Add an observable gauge xrpld_reduce_relay_metrics{metric} that reads
Overlay::txMetrics() and parses its rolling-average fields:
- selected_peers (txr_selected_cnt)
- suppressed_peers (txr_suppressed_cnt)
- not_enabled_peers (txr_not_enabled_cnt)
- missing_tx_freq (txr_missing_tx_freq)
The JSON values are decimal strings (std::to_string), parsed via std::stoll —
the same JSON-reading pattern as registerNodeStoreGauge. No new Overlay
accessor or core-interface change required.

InboundLedger drives ledger back-fill and fork recovery with timeout/retry
logic (kLedgerTimeoutRetriesMax = 6), but emitted only a global ledger_fetches
counter — sync/recovery cost was a telemetry blind spot.
Add a ledger.acquire span that wraps the acquisition lifecycle:
- Started in InboundLedger::init() with ledger_seq and acquire_reason
(history / consensus / generic, mirroring InboundLedger::Reason).
- Finalized in InboundLedger::done() with outcome (complete / failed),
timeouts, and peer_count, then reset so the span duration is exported.
Held as a std::optional<SpanGuard> member (same pattern as RCLConsensus
roundSpan_). New op/attr/val constants added to LedgerSpanNames.h. Compiles to
a no-op when telemetry is disabled via the SpanGuard fallback.

The transaction queue had no metric for demand that leaves or never enters the
queue, so fee-underpayment abandonment and admission-control rejection were
invisible (distinct from jq_trans_overflow, which is the job queue).
Add two synchronous counters via MetricsRegistry:
- xrpld_txq_expired_total — incremented in TxQ::processClosedLedger() for each
queued transaction removed because its LastLedgerSequence passed (submitters
who under-bid the escalating fee and were never included).
- xrpld_txq_dropped_total{reason} — incremented in TxQ::apply() at the
queue-full admission-control returns (reason="queue_full").
Both reach MetricsRegistry via the Application& parameter already passed to
these methods; calls are null-guarded so they no-op when telemetry is disabled.

LedgerHistory::handleMismatch() already classifies a built-vs-validated ledger
mismatch (prior ledger, close time, consensus tx set, same/different tx set),
but only bumped a single untyped beast::insight counter — the reason was
dropped. Fork diagnosis was therefore a log-grep exercise.
Add a labeled OTel counter so the mismatch reason is a queryable time series:
- MetricsRegistry: new ledgerHistoryMismatchCounter_ + incrementLedgerHistoryMismatch(reason)
- LedgerHistory: record one reason per classification branch (unknown,
prior_ledger, close_time, consensus_txset, same_txset_diff_result,
different_txset). Reaches MetricsRegistry via the existing app_ reference.
The existing beast::insight mismatchCounter_ is left intact.

The xrpld_peer_quality{metric="peers_insane_count"} gauge was hardcoded to 0.0
with a TODO, leaving the "Insane/Diverged Peers" panel permanently empty.
PeerImp::json() already exposes the peer's tracking state via the "track"
field (set to "diverged" when tracking_ == Tracking::Diverged). The peer-quality
callback already iterates peer->json() for latency and version, so count peers
whose "track" field equals "diverged" in the same loop — no change to the
abstract Peer interface required.

A phase-8->phase-9 merge (a675897aaf) duplicated the "Consensus Outcome
Distribution" and "Consensus Failures Over Time" panels: both appeared twice
with byte-identical queries (verified ignoring gridPos). The pair existed once
on phase-6/7/8 and became two on phase-9 only, so the duplication originated
in phase-9's own merge history.

Both metrics are already emitted and live in Prometheus but were not fully
visualised.
- Fee Market (xrpld-fee-market.json): "Load Factor Attribution (Stacked
Components)" — stacks load_factor_fee_escalation / fee_queue / local / net /
cluster so an operator can see which component drives the effective fee. The
existing panels showed the aggregate only.
- Validator Health (xrpld-validator-health.json): "Agreement % (7d)" and
"Agreements vs Missed (7d)" — the xrpld_validation_agreement gauge already
observes agreement_pct_7d / agreements_7d / missed_7d, but the dashboard only
plotted 1h and 24h windows.
Panels follow the existing template: $node filter, exported_instance in legends,
Title Case, axis labels.

The grpc.{Method} spans (GRPCServer.cpp) and pathfind.* spans (PathRequest.cpp)
are emitted but had no dashboard coverage. The existing RPC & Pathfinding
dashboard only plotted StatsD timers. Add span-derived rows:
- gRPC Request Rate by Method (grpc.* by method)
- gRPC Latency P95 by Method
- gRPC Error Rate by Status (by grpc_status)
- Pathfinding Compute Duration (pathfind.compute p95/p50)
- Pathfinding Request & Discovery Rate (pathfind.request / pathfind.discover)
otel-collector-config.yaml: add method, grpc_role, grpc_status spanmetrics
dimensions (bounded value sets). Add a $grpc_method template variable so the
gRPC panels can be filtered by method, consistent with the dashboard filter
conventions.
Note: these spans populate only when the node serves gRPC / pathfinding
traffic; they are correct but not exercised by the current health-check
workload (they will be covered by the Phase 10 workload generator).

The consensus state-machine and TxQ lifecycle spans are emitted by the code
and present in Prometheus, but no panel visualised them. Add panels keyed on
those span_names (verified live) plus the low-cardinality dimensions needed to
break them down.
Consensus Health (consensus-health.json) — new rows:
- Consensus Round Duration (full round, p95/p50, mode-filterable)
- Consensus Phase Duration (open vs establish breakdown)
- Position Update Duration (update_positions p95/p50)
- Consensus Stall Rate (consensus.check by consensus_stalled)
- Consensus Mode-Change Rate by Target Mode (mode_change by mode_new)
Transaction Overview (transaction-overview.json) — new rows:
- TxQ Enqueue Rate by Transaction Type (txq.enqueue by tx_type)
- Queue Bypass Ratio (txq.apply_direct vs txq.enqueue)
- Queue Accept (Drain) Duration per Ledger (txq.accept p95/p50)
- Queue Cleanup Rate (txq.cleanup expired entries)
otel-collector-config.yaml — add spanmetrics dimensions for the lifecycle
breakdowns: mode_new, consensus_stalled, consensus_phase, consensus_result
(all bounded value sets, safe as Prometheus labels).
All new panels follow the existing dashboard template: $node filter,
exported_instance in every legend, Title Case, axis labels, row layout.

The spanmetrics connector dimension was `xrpl.consensus.mode`, but the code
emits the span attribute under the bare key `consensus_mode` (matching every
other dimension after the Phase 6 rename). The mismatch left the
`xrpl_consensus_mode` Prometheus label empty, so the Consensus Health
"Consensus Mode Over Time" panel and the `$consensus_mode` template variable
(which filters every panel) matched no live series.
- otel-collector-config.yaml: dimension `xrpl.consensus.mode` -> `consensus_mode`
- consensus-health.json: 11 label refs `xrpl_consensus_mode` -> `consensus_mode`
(the `$consensus_mode` Grafana variable name is unchanged)
- telemetry-runbook.md: refresh the stale spanmetrics label table to the bare
names actually emitted (command/rpc_status/consensus_mode/local/
proposal_trusted/validation_trusted), fix dotted->bare attribute names in
span tables and TraceQL examples (tx_hash, ledger_seq, consensus_round_id,
consensus_ledger_id, consensus_round, tx_id event attr), correct the
consensus_round_id query to int (not quoted string), and fix the
load_type value query ("exception_rpc" -> "exceptioned RPC").
Verified against the live stack: Tempo span tags confirm bare attribute keys
(consensus_mode, ledger_seq, tx_hash, ...); the populated xrpl_consensus_mode
series in Prometheus is stale retained data from an older build.

beast::insight metrics exported via OTLP carried no exported_instance
label because [insight] omitted service_instance_id (only [telemetry]
set it). Every system-* dashboard filters insight metrics with
exported_instance=~"$node", and the $node template variable is sourced
from label_values(..., exported_instance) — so with the label absent,
$node was empty and all insight-backed panels showed no data.
Add service_instance_id to [insight] in both telemetry configs, matching
the [telemetry] value (xrpld-mainnet / xrpld-devnet). CollectorManager
already reads this key and passes it to OTelCollector, which sets the
service.instance.id resource attribute.

The system-* dashboards queried the legacy StatsD rippled_ prefix, but the
node now emits beast::insight metrics via native OTLP under the xrpld_
prefix (config: [insight] server=otel, prefix=xrpld). All queries returned
no data.
Migration (names derived from C++ beast::insight registrations, not live
Prometheus, since a syncing node does not emit every metric yet):
- rippled_ -> xrpld_ prefix across all panel queries and template variables
(including the $node variable query, which broke the whole dashboard filter)
- Histogram Event instruments export with unit ms, so bare _bucket becomes
_milliseconds_bucket: ios_latency, rpc_time, rpc_size, pathfind_fast/full
- Job-type metrics were StatsD summaries (label quantile="$quantile"); on the
OTLP path they are histograms. Converted those queries to
histogram_quantile($quantile, rate(xrpld_<job>_milliseconds_bucket[5m]))
and added the previously-undefined $quantile template variable
- Per-job-type detail panels: __name__ regex now matches _milliseconds_bucket
No panels removed. Panels for metrics not yet emitted (e.g. warn/drop, or
job types the syncing node has not run) show no data until the path executes.

P100 from a histogram is degenerate — it always returns the upper bound of
the highest populated bucket (a single slow outlier pins it to the top
boundary), producing a flat line. Revert to meaningful quantiles:
- Job Queue Wait Time / Job Execution Time: p75 (typical) + p99 (tail)
- Per-Job-Type / Per-Method: p99
- Added gauge panels showing current p99 with green/yellow/red thresholds

Two stray "rippled" tokens introduced by 43258e8d ("docs(telemetry):
add secure-OTel pipeline analysis…") were caught by check-rename in
CI. Re-run docs.sh to convert them to xrpld so the rename check
passes on PR #6425 (and downstream PR #6426 once merged up).

Brings in pratik/otel-phase3-tx-tracing's two commits that move all
consensus-tracing content off phase-3:
- c9521b97fe refactor(telemetry): pull consensus-tracing scope-leak
out of phase-3
- d6b101069e refactor(telemetry): remove consensus tracing from
phase-3
Phase-4 already owns this content (with the consensus_span -> cons_span
namespace rename, round/accept/proposalSend/validationSend span
construction, and the relocated ConsensusSpanNames.h under
src/xrpld/consensus/), plus its own evolution on top — so the merge is
resolved as a tree-identity merge:
- src/xrpld/app/consensus/ConsensusSpanNames.h: keep phase-4's
renamed/expanded version (modify/delete conflict, resolved with
--ours).
- src/xrpld/app/consensus/RCLConsensus.cpp: keep phase-4's version
with cons_span attribute calls, the trace_context inject blocks
on broadcastPropose/validate, the secure-OTel TODO, and the
full validation/round span instrumentation (content conflict,
resolved with --ours).
- src/xrpld/overlay/detail/PeerImp.cpp: keep phase-4's version with
the proposalReceiveSpan/validationReceiveSpan calls, lambda span
captures, and cons_span::attr::* setAttribute calls (content
conflict, resolved with --ours).
- src/xrpld/telemetry/ConsensusReceiveTracing.h: phase-3 deleted it,
phase-4 still uses it. Restored from phase-4 HEAD (silent
auto-deletion otherwise).
- include/xrpl/telemetry/TraceContextPropagator.h: phase-3 stripped
consensus references and the secure-OTel TODO; phase-4 still has
both. Restored from phase-4 HEAD.
- src/xrpld/telemetry/PropagationHelpers.h: phase-3 swapped the
@see ConsensusReceiveTracing.h cross-reference for TxTracing.h;
phase-4 still wants the consensus reference. Restored from
phase-4 HEAD.
Net tree change on phase-4: zero. Verified via 'git diff <pre-merge-sha>
HEAD' returning empty.

Phase-3 (PR #6425) is scoped to transaction tracing only; consensus
tracing belongs to phase-4 (PR #6426). The previous commit on this
branch removed the namespace/attribute scaffolding c6c019ed8b leaked
into phase-3, but phase-3 still carried the consensus span construction
and trace-context propagation introduced in earlier commits
(61cb1faf8f, 93bed03d8d). Move that out too so phase-3 creates and
propagates no consensus spans of any kind.
Removed:
- src/xrpld/telemetry/ConsensusReceiveTracing.h (deleted; phase-4
owns it).
- PeerImp.cpp: remove the std::make_shared<SpanGuard>(
proposalReceiveSpan(...))/validationReceiveSpan(...) constructions
in onMessage(TMProposeSet)/onMessage(TMValidation), drop the
sp = std::move(span) lambda captures, and drop the
#include <xrpld/telemetry/ConsensusReceiveTracing.h>.
- RCLConsensus.cpp: drop the two telemetry::injectToProtobuf() blocks
that injected the active trace context into TMProposeSet (in
Adaptor::propose, after addSuppression) and TMValidation (in
Adaptor::validate, around the broadcast call). Drop the now-unused
#include of TraceContextPropagator.h and the
XRPL_ENABLE_TELEMETRY-gated include of
opentelemetry/context/runtime_context.h.
- TraceContextPropagator.h: update file-level @see comment to drop
the ConsensusReceiveTracing.h reference and to scope the
"wired into the P2P message flow via PropagationHelpers.h"
sentence to TMTransaction only.
- PropagationHelpers.h: replace the
@see ConsensusReceiveTracing.h cross-reference with
@see TxTracing.h.
Inert consensus metadata (TraceCategory::Consensus enum value,
seg::consensus constant, isCategoryEnabled/categoryToSpanKind switch
arms, the SpanGuard.h doc-comment example) is intentionally preserved
on phase-3: nothing references it after this commit, but phase-4
needs it and removing it would widen the phase-3 -> phase-4 merge
surface for no benefit.
Verified via git grep: no remaining phase-3 references to
proposalReceiveSpan, validationReceiveSpan, ConsensusReceiveTracing,
consensus_span::, consensus.proposal, or consensus.validation.

Commit c6c019ed8b ("addressed code review comments") bundled tx-tracing
review fixes with consensus-tracing scaffolding that belongs on
pratik/otel-phase4-consensus-tracing (PR #6426). This commit lifts the
consensus-only parts back out of phase-3 so PR #6425 stays scoped to
transaction tracing. Phase-4 already carries the same content (via prior
phase-3 -> phase-4 merges) plus its own evolution on top, so nothing is
moved across — only removed here.
Removed:
- src/xrpld/app/consensus/ConsensusSpanNames.h (deleted; phase-4 owns
it).
- PeerImp.cpp: revert onMessage(TMProposeSet)/onMessage(TMValidation)
consensus-attr setAttribute calls to the hardcoded
"xrpl.consensus.{trusted,round,ledger.seq}" strings used before
c6c019ed8b. Drop the now-unused
#include <xrpld/app/consensus/ConsensusSpanNames.h>.
- RCLConsensus::Adaptor::validate(): remove the
TODO(observability/secure-OTel) block on validation trace_context.
- TraceContextPropagator.h: remove the TODO(observability/secure-OTel)
block on injectToProtobuf().
Tx-tracing parts of c6c019ed8b are intentionally untouched.
No phase-3 caller of telemetry::consensus_span:: remains; verified via
git grep. No test on phase-3 references the removed header.

Document the threat model and chosen hardening approach for the OTel
pipeline: mTLS to the collector as primary defense (across-network
deployment), NetworkPolicy as defense-in-depth, and source-side
validation plus per-peer rate limiting for protocol::TraceContext on
peer messages. Skips Basic Auth (wrong shape for multi-operator
fleet) and HTTP-gateway header stripping (rippled is P2P).
Wires the new doc into the master plan ToC, mermaid diagram, and
body section, plus cross-refs from the privacy section in
02-design-decisions.md and the collector config in
05-configuration-reference.md so readers reach it from natural
in-context entry points. Adds a backlink at the top of secure-OTel.md
to the master plan.
Adds 'exfiltration' and 'htpasswd' to cspell dictionary.

- Drop xrpl.node.amendment_blocked / xrpl.node.server_state from telemetry
surface (constants in SpanNames.h, two filters in tempo.yaml). Operators
read the same data via server_info / server_state RPC; OTel SDK 1.18.0
cannot refresh resource attrs at runtime so resource-level emission was
not viable either.
- Namespace all pathfind span attributes under pathfind_* (underscore form
per Phase 1c rule 5). Renames in PathFindSpanNames.h and call sites in
PathRequest.cpp, PathRequestManager.cpp, plus the rule-5 retention
xrpl.pathfind.ledger_index -> pathfind_ledger_index.
- Wire pathfind_source_account / pathfind_dest_account on pathfind.request
in doPathFind / doRipplePathFind handlers (only when present + string).
- Collapse per-asset pathfind.discover / pathfind.rank spans into one
pathfind.discover hoisted around the per-source-asset loop in
PathRequest::findPaths. Span count goes from 2N to 1 per RPC call;
per-asset breakdown traded for bounded storage and cardinality. Trade-off
documented inline.
- Fix pathfind_num_paths semantics: now sums getBestPaths().size() across
the loop (paths actually returned) instead of the maxPaths input cap.
- PathRequestManager::updateAll: move span creation after the locked
requests_ snapshot, early-return when no active subscriptions exist
(avoids empty span on every ledger close), set pathfind_num_requests
= requests.size().
- Update Phase2_taskList.md and 02-design-decisions.md to match.

Per PR #6438 review thread r3250432621: known-command errors
(rpcTOO_BUSY, rpcNO_PERMISSION, etc.) were collapsing into a
single rpc.command.unknown span name, hiding per-command error
rates in dashboards. Same anti-pattern existed for gRPC, where
every method was bucketed under grpc.request with the method
relegated to an attribute.
- RPCHandler.cpp: doCommand error path uses cmdName as the span
suffix; the rpc_span::val::unknownCommand fallback only applies
when the request truly omits both command and method fields.
- GRPCServer.cpp: gRPC span name is now grpc.<MethodName>
(e.g. grpc.GetLedger). Method also retained as an attribute.
- GrpcSpanNames.h: drop the unused op::request constant; update
the span-hierarchy comment.
- RpcSpanNames.h: update the gRPC span diagram to match.
Dashboards on downstream phases will benefit from per-command
breakdowns without needing TraceQL attribute filters.

Three interrelated fixes in otel-collector-config.yaml; without them the
Phase 8 log-trace correlation pipeline is silently broken.
1. `resource/logs` processor now upserts `job: xrpld` alongside
`service.name: xrpld`. Loki 3.x OTLP ingestion renames
`service.name` to the label `service_name`, so the runbook /
integration-test queries (`{job="xrpld"} |= "trace_id="`) returned
empty. Upserting the `job` resource attribute at the collector lets
the canonical Loki label flow through unchanged.
2. `filelog` regex makes the `partition:` capture non-capturing-optional.
`Logs::format()` omits the `partition:` prefix when partition is
empty (common for framework-level log lines); the old regex required
it and silently dropped those records.
3. Timestamp parser now matches the real log format. `Logs::format()`
writes microsecond-precision timestamps like
`2026-04-15 10:30:45.123456 UTC`. The layout was
`%Y-%b-%d %H:%M:%S` — missing fractional seconds and timezone —
which failed strptime and dropped timestamps. New layout is
`%Y-%b-%d %H:%M:%S.%f` with `location: UTC`.
Also adds a block-comment documenting the real log format so the
next person to touch this doesn't re-introduce the same gaps.
- `src/test/telemetry/MetricsRegistry_test.cpp` (Beast `unit_test::suite`
format under `src/test/`) duplicates the GTest version already
maintained at `src/tests/libxrpl/telemetry/MetricsRegistry.cpp`.
Project rule (`tasks/lessons.md` §Test Format): all new tests use
GTest under `src/tests/libxrpl/`. The GTest version exercises the
same four cases (disabled construction, start/stop lifecycle, recording
no-op, destructor-calls-stop). Deleting the Beast duplicate eliminates
drift and keeps the test authoritative in one place.
- Drop the matching `test.telemetry > xrpl.basics/xrpl.core/xrpld.telemetry`
entries from `.github/scripts/levelization/results/ordering.txt`
because `xrpl.test.telemetry` (the GTest binary) retains its own
entries; the removed ones belonged to the deleted Beast suite.
- `.claude/instructions.md` was committed as a symlink to an
author-local absolute path (`/home/pratik/sourceCode/personal/Rippled/
instructions.md`) that does not exist for any other contributor or in
CI. Remove the symlink from git tracking and add `.claude/` to
`.gitignore` so future agent commits do not re-add per-developer
settings.
MetricsRegistry observable-gauge callbacks run on the OTel reader thread
and read live state from nodeStore_, overlay_, networkOPs_, ledgerMaster,
inboundLedgers, loadManager, and others. The old shutdown sequence called
metricsRegistry_->stop() AFTER all those services were already stopped,
which left a race window between each service's stop() and the final
provider_->ForceFlush() during which a callback could dereference
already-stopped service state. The try/catch guards in each callback
mitigated crashes but not reads from freed members.
- Add MetricsRegistry::detachCallbacks() that sets an atomic<bool>
callbacksDetached_ with release ordering. Idempotent.
- Guard every ObservableGauge callback entry with an acquire-load of the
same flag and return early if it is set. Covers all 15 registered
callbacks (cacheHitRate, txq, objectCount, loadFactor, nodeStore,
serverInfo, buildInfo, completeLedgers, dbMetrics, validatorHealth,
peerQuality, ledgerEconomy, stateTracking, storageDetail,
validationAgreement).
- Application::run() shutdown sequence now calls
metricsRegistry_->detachCallbacks() right after m_loadManager->stop()
and BEFORE m_shaMapStore, m_jobQueue, overlay_, grpcServer_,
m_networkOPs, serverHandler_, m_ledgerReplayer, m_inboundTransactions,
m_inboundLedgers, ledgerCleaner_, m_nodeStore, perfLog_ are stopped.
The acquire/release pair guarantees subsequent reader-thread ticks see
the detach before they dereference stopped services.
- metricsRegistry_->stop() keeps setting the flag as a belt-and-suspenders
defense in case a future caller forgets to detach first.
- Drop the misleading "No explicit RemoveCallback is needed" comment
from stop(); provider destruction alone does not beat the reader
thread to already-freed state.
The objectCountGauge callback previously discarded its state pointer
via `void* /* state */`; restore the state argument so it can access
self->callbacksDetached_ too.
File renames to match the post-docs.sh project-wide rename + the UID
rename applied in the previous commit. Five phase-9 dashboards are
affected:
- rippled-fee-market.json -> xrpld-fee-market.json
- rippled-job-queue.json -> xrpld-job-queue.json
- rippled-peer-quality.json -> xrpld-peer-quality.json
- rippled-rpc-perf.json -> xrpld-rpc-perf-otel.json
- rippled-validator-health.json-> xrpld-validator-health.json
`rippled-rpc-perf.json` is renamed to `xrpld-rpc-perf-otel.json` (rather
than `xrpld-rpc-perf.json`) to avoid colliding with the
phase-6 `rpc-performance.json` dashboard which also uses the
`xrpld-rpc-perf` UID. The new filename matches its now-unique
`xrpld-rpc-perf-otel` UID that was set in the merge commit.
Phase 4 added a span catalog in `06-implementation-phases.md` listing the
source location for each consensus span. Line numbers `Consensus.h:707`,
`RCLConsensus.cpp:232/341/492/541/900` drift on every refactor and would
become stale PR after PR. Filename alone is enough for operators to
grep — the RCLConsensus.cpp spans are already unambiguous from the span
name itself.
Follow-up to the phase-6 dashboard cleanup. The three dashboards
introduced by commit f6105ece98 (consensus-health, rpc-performance,
transaction-overview) were missed in the initial UID rename and still
carried `rippled-*` UIDs plus line-number refs in panel descriptions.
- UIDs: `rippled-consensus` -> `xrpld-consensus`,
`rippled-rpc-perf` -> `xrpld-rpc-perf`,
`rippled-transactions` -> `xrpld-transactions`, matching the
post-`docs.sh`-rename runbook and the other dashboards in this PR.
- Strip `:<line>` suffixes from `ServerHandler.cpp`, `RCLConsensus.cpp`,
`NetworkOPs.cpp`, etc. references in panel descriptions. Line numbers
drift on every refactor; the filename is enough to grep.
- Fix the Overall RPC Throughput panel: two targets filtered on
`span_name="rpc.request"` (never emitted) instead of
`span_name="rpc.http_request"` (the real emitted name). The panel
would have shown zero data until this fix.
Follow-up to the dashboard cleanup on this branch. Caught additional sites
in TESTING.md that still reference the never-emitted `rpc.request` span:
- TraceQL query examples in Step 5 "Verify traces in Tempo" now filter on
`name="rpc.http_request"` (the real emitted name).
- Expected-spans table replaces `rpc.request` with `rpc.http_request`.
- Query loop under the Prometheus verification section now iterates over
the full set of emitted RPC entry-point names
(`rpc.http_request`, `rpc.ws_upgrade`, `rpc.ws_message`, `rpc.process`).
Also drop `exporter=otlp_http` from the sample telemetry config block.
`TelemetryConfig.cpp` does not parse an `exporter` key in any phase through
Phase 8; only OTLP/HTTP is wired up, so the line is either a silently
ignored no-op or misleading documentation.
Phase-6 introduces ledger-operations, peer-network, and the five StatsD
dashboards. Align them with the rest of the chain:
- Rename dashboard UIDs from `rippled-*` to `xrpld-*` so the provisioned
UIDs match the post-rename-script documentation (`docs.sh` rewrites
.md but not .json, so the two drifted). Runbook references
`xrpld-rpc-perf`, `xrpld-transactions`, etc., now the JSON matches.
- Add the `$node` template variable + `exported_instance=~"$node"` filter
to every target in the five `statsd-*` dashboards. Mirrors the pattern
already used by consensus-health, ledger-operations, and peer-network
per the project rule that every dashboard must support per-node
filtering.
- Strip `:<line>` (and `:NN-NN` range) suffixes from C++ file references
in every dashboard panel description and in docker/telemetry/TESTING.md.
Line numbers drift on every refactor; the filename alone is enough to
grep.
- Replace stale `rpc.request` entries with the real emitted span names
(`rpc.http_request`, `rpc.ws_upgrade`, `rpc.ws_message`, `rpc.process`)
in TESTING.md so operators can copy-paste the filters and hit real
traces.
- Also drop the `:706` line ref from the `StatsDCollector.cpp` callout
in `06-implementation-phases.md`.
- RPC Spans table: `rpc.request` was documented but the code actually emits
`rpc.http_request`. Listed the actual emitted names
(`rpc.http_request`, `rpc.ws_upgrade`, `rpc.ws_message`, `rpc.process`)
and their parent/child relationship.
- Drop `:<line>` suffixes from Source File columns in both RPC and
Transaction span tables. Line numbers drift with every refactor; the
filename is enough for operators to grep.
- Summary table: replace the never-emitted `rpc.request` row with the real
entry points so `span_name=` filters in PromQL / TraceQL match.
Phase-1a plan documents advertised OTLP/gRPC on port 4317 as the default
exporter, four unparsed [telemetry] config keys, and "Phase 4a Complete"
status with exit-criteria checkboxes marked done. Every downstream branch
through Phase 5 ships only OTLP/HTTP on port 4318 via OtlpHttpExporterFactory,
never parses the advertised keys, and the Phase 4 work is not yet delivered.
Fixes:
- 02-design-decisions.md: flip §2.1.1 SDK dependency recommendations to
OTLP/HTTP (shipped) with OTLP/gRPC marked Future. Update §2.2 architecture
diagram and text from OTLP/gRPC:4317 to OTLP/HTTP:4318. Rewrite §2.2.1 as
"OTLP/HTTP (Shipped)" and §2.2.2 as "OTLP/gRPC (Future Work — Planned
Upgrade)" with a concrete checklist (Conan dep, config parsing, factory
branch, runbook/dashboard updates) for landing the gRPC transport later.
- 05-configuration-reference.md: drop the fabricated exporter/otlp_grpc key
and the :4317 default from the sample config block and the options-summary
table. Move trace_pathfind, trace_txq, trace_validator, trace_amendment
into a new "Planned (not yet implemented)" table citing the phase that will
add each one. Keep the example config minimal so copy-paste does not produce
a silently-ignored stanza.
- 06-implementation-phases.md: reset Phase 4 Exit Criteria checkboxes from
[x] to [ ] (Phase 4 is not shipped at Phase-1a time). Rename "Phase 4a
Complete" to "Phase 4a Plan" and describe the work as future. Replace the
broken forward link to Phase4_taskList.md (introduced in the Phase 2 PR)
with a sentence pointing readers to where that spec will land. Renumber
the final section 6.12 to 6.11 so it sits directly after 6.10; section 6.11
("Effort Summary") was intentionally removed in earlier edits.
SpanGuard::span() hardcoded SpanKind::kInternal for every span. Tempo's
service-graph and spanmetrics RED calculations rely on kServer /
kConsumer / kClient / kProducer to classify inbound vs outbound vs
internal operations. With kInternal everywhere, the service graph
collapses to a single self-loop and RED metrics attribute all latency
to internal work.
Add categoryToSpanKind() mapping:
- Rpc -> kServer (inbound synchronous request)
- Peer -> kConsumer (inbound async peer message)
- Transactions -> kInternal
- Consensus -> kInternal
- Ledger -> kInternal
Only the single-argument overload is affected; childSpan / linkedSpan
continue to default to kInternal because they represent in-process
continuations of an already-kinded parent.
Spanmetrics dimensions used xrpl.rpc.command etc. but C++ emits bare
"command". Tempo tags for phase6-added consensus/tx/peer filters used
qualified names but C++ uses bare names. Dashboard panel referenced
xrpl_tx_suppressed (never populated) instead of suppressed.

Phase 10's workload validation configs (expected_metrics.json,
regression-metrics.json, validate_telemetry.py) queried the
MetricsRegistry metrics under the rippled_ prefix, but MetricsRegistry
emits them as xrpld_ (see MetricsRegistry.cpp). On a live run the
workload validator reported every MetricsRegistry metric as missing,
masking genuine regressions.
Rename the following to xrpld_ across the workload validator,
expected-metrics manifest, and regression-metrics template:
- nodestore_state, cache_metrics, txq_metrics, load_factor_metrics,
object_count
- rpc_method_started_total / _finished_total / _errored_total /
_duration_us
- job_queued_total / _started_total / _finished_total /
_queued_duration_us_bucket / _running_duration_us_bucket
- peer_quality, server_info, validator_health, ledger_economy,
db_metrics, complete_ledgers, build_info, state_tracking,
storage_detail
- ledgers_closed_total, validations_sent_total,
validations_checked_total, state_changes_total
- validation_agreement, validation_agreements_total,
validation_missed_total
Mirrors the phase-9 fix in commit 5601615952.

"xrpld_cache_metrics", etc.), but the Phase 9 dashboards and the
Step 10c integration-test assertions introduced in 892fee638a
queried the rippled_ prefix. Every Phase 9 panel and assertion
therefore rendered "No data" or failed on a live run, even though
the underlying series were being exported correctly.
Rename the rippled_ prefix to xrpld_ for every MetricsRegistry
metric in dashboards and the integration test:
- nodestore_state, cache_metrics, txq_metrics, load_factor_metrics,
object_count
- rpc_method_started_total / _finished_total / _errored_total /
_duration_us_bucket
- job_queued_total / _started_total / _finished_total /
_queued_duration_us_bucket / _running_duration_us_bucket
- peer_quality, server_info, validator_health, ledger_economy,
db_metrics, complete_ledgers, build_info, state_tracking
- ledgers_closed_total, validations_sent_total,
validations_checked_total, state_changes_total
- validation_agreement (ValidationTracker 1h/24h/7d windows)
Also add ValidationTracker window-gauge assertions to Step 10c of
integration-test.sh so the 1h/24h/7d agreement and miss counts are
checked alongside the other Phase 9 gauges.
The rippled_ prefix is preserved for beast::insight metrics
(rippled_LedgerMaster_*, rippled_Peer_Finder_*, rippled_total_*,
rippled_Overlay_*, rippled_State_Accounting_*, rippled_transactions_*,
rippled_proposals_*, rippled_validations_Messages_*) because those
flow through the StatsD-style OTelCollector configured with
`[insight] prefix=rippled` and remain on that prefix by design.
Verified against a live 6-node consensus network: all 22 Phase 9 +
ValidationTracker assertions now report 6+ series per metric.

Two fixes so gauges register in Prometheus (via StatsD) even when their
initial/steady-state value is 0:
1. StatsDGaugeImpl m_dirty: default-init to true so the initial value
(0) is emitted on the first flush. Previously, gauges whose value
never changed from 0 were never flushed and never appeared
downstream.
2. io_latency_sampler firstSample_: new atomic<bool>, init true.
m_event.notify now fires when either firstSample_ is true (exchanged
to false) or lastSample >= 10 ms. This guarantees the io_latency
metric is registered on startup; subsequent sub-10 ms samples are
still suppressed to avoid flooding.
Set defaults for tx_span::attr::suppressed (false) and
tx_span::attr::status ("new") immediately after creating the txReceive
span. Without defaults, spans whose suppressed/status attributes would
only be set in the HashRouter-suppressed branch lacked these attributes
entirely, producing incomplete span data in downstream stores.
The suppressed branch still overrides these when the transaction has
already been seen via HashRouter.
Two build failures surfaced by CI on the Phase 9 branch:
1. NetworkOPsImp stores the ServiceRegistry as
std::reference_wrapper<ServiceRegistry> registry_, so calls must go
through registry_.get().<method>(). The MetricsRegistry hooks added
in setMode() and recvValidation() dereferenced the wrapper directly,
which compiles against a pre-existing accessor on the wrapper type
on some toolchains but fails on clang 16/17/20 and gcc 13/15 with
"no member named 'getMetricsRegistry' in
std::reference_wrapper<xrpl::ServiceRegistry>".
2. MetricsRegistry::app_ and MetricsRegistry::journal_ are only used
inside XRPL_ENABLE_TELEMETRY-guarded code paths (gauge callbacks
and JLOG). When telemetry is disabled, clang's
-Werror=-Wunused-private-field tripped. Move the two fields under
the same #ifdef and guard the constructor initialisers with
[[maybe_unused]] so the no-op build continues to compile cleanly.
Addresses code review findings on PR #6513:
1. registerAsyncGauges() was ~730 lines, violating the CLAUDE.md
rule "No function longer than 80 lines." Split into fifteen
per-domain helpers (cache, TxQ, object count, load factor,
NodeStore, server info, build info, complete ledgers, DB,
validator health, peer quality, ledger economy, state tracking,
storage detail, validation agreement) dispatched from a thin
shell. Each helper now stays at or below the 80-line limit.
2. PerfLogImp::rpcEnd() only updated the in-memory counter and
never advanced the OTel xrpld_rpc_method_finished_total,
xrpld_rpc_method_errored_total, or xrpld_rpc_method_duration_us
instruments. rpcStart() was already wired up, so the finished
and errored counters stayed at zero for every RPC call.
rpcEnd() now computes the duration once, records it under the
existing mutex, and forwards finish/error events to
MetricsRegistry::recordRpcFinished / recordRpcErrored outside
the counter mutex to avoid lock nesting with the OTel SDK.
3. Added class-level Doxygen for MetricsRegistry with an ASCII
collaborator diagram and explicit @note tags covering
thread-safety, lifetime, and extension guidance.
Tempo /api/traces/{id} returns OTLP-shaped JSON with a top-level
"batches" key, not "data". The cross-check in check_log_correlation
was querying jq '.data | length' which always returned null, causing
the Log-Tempo cross-check to fail even when the trace existed.
MockServiceRegistry in MetricsRegistry.cpp still used the old method
names (timeKeeper, cachedSLEs, validators, overlay, cluster, app, etc.)
while ServiceRegistry has been standardized on getXxx()/isXxx() forms.
Windows CI caught this as C3668 "did not override any base class methods"
errors and C2259 "cannot instantiate abstract class".
Rename all 13 mismatched overrides to match the current interface:
timeKeeper -> getTimeKeeper
cachedSLEs -> getCachedSLEs
validators -> getValidators
validatorSites -> getValidatorSites
validatorManifests -> getValidatorManifests
publisherManifests -> getPublisherManifests
overlay -> getOverlay
cluster -> getCluster
peerReservations -> getPeerReservations
pendingSaves -> getPendingSaves
openLedger (x2) -> getOpenLedger
getPathRequests -> getPathRequestManager (type rename too)
journal -> getJournal
logs -> getLogs
trapTxID -> getTrapTxID
app -> getApp
Also regenerate levelization ordering.txt to reflect the new
tests.libxrpl -> xrpl.core edge introduced by ServiceRegistry.h include.

Consensus.h (Phase 4 tracing) depends on DisputedTx::getYays()/getNays()
to build disputeResolve span events. Both accessors were removed by
earlier 'duplicate accessor' cleanup commits on this branch, leaving
Consensus.h referencing non-existent members. CI caught this on
macOS/clang-17/gcc-13/Windows builds.
Restore the accessors on the branch where they were dropped so downstream
phase branches inherit a compiling DisputedTx.h via merge.

Remove the span-replacement logic in startRoundTracing() that was
discarding the hash-derived round span and replacing it with a linked
span (which gets a random trace_id). The deterministic trace_id from
the ledger hash is the key feature enabling cross-node correlation —
replacing it broke correlation on all rounds after the first.
Also: use thread_local mt19937 for hashSpan() span IDs (same fix as

Instrument the consensus subsystem with OpenTelemetry spans covering
the full round lifecycle: round start, establish phase, proposal send,
ledger close, position updates, consensus check, accept, validation
send, and mode changes.
Key design choices adapted from the original Phase 4 implementation
to the new SpanGuard factory pattern introduced in Phase 3:
- Add SpanGuard::hashSpan() for category-gated hash-derived trace IDs
(consensus round spans share trace_id across validators via ledger hash)
- Add SpanGuard::addEvent() overload with key-value attribute pairs
(used for dispute.resolve events during position updates)
- Add ConsensusSpanNames.h with compile-time span name constants
following the colocated *SpanNames.h pattern from Phase 3
- Add consensusTraceStrategy config option ("deterministic"/"attribute")
for cross-node trace correlation strategy selection
- Use SpanGuard::linkedSpan() for follows-from relationships between
consecutive rounds and cross-thread validation spans
- Use SpanGuard::captureContext() for thread-safe context propagation
from consensus thread to jtACCEPT worker thread
Spans produced: consensus.round, consensus.proposal.send,
consensus.ledger_close, consensus.establish, consensus.update_positions,
consensus.check, consensus.accept, consensus.accept.apply,
consensus.validation.send, consensus.mode_change

Replace SpanGuard::txSpan(prefix, name, hash) with the generic
SpanGuard::hashSpan(TraceCategory, name, hash) that accepts a
TraceCategory parameter instead of hardcoding Transactions. This
enables reuse for consensus round spans (Phase 4) and any future
subsystem needing deterministic cross-node trace correlation via
hash-derived trace IDs.
Both overloads are replaced:
- hashSpan(cat, name, hash, size) — standalone with random span_id
- hashSpan(cat, name, hash, size, parentSpanId, parentSize, flags)
— with remote parent from protobuf context propagation
Add full span name constants (tx_span::receive, tx_span::process)
to TxSpanNames.h following the ConsensusSpanNames.h pattern.

Replace SpanGuard::txSpan(prefix, name, hash) with the generic
SpanGuard::hashSpan(TraceCategory, name, hash) that accepts a
TraceCategory parameter instead of hardcoding Transactions. This
enables reuse for consensus round spans (Phase 4) and any future
subsystem needing deterministic cross-node trace correlation via
hash-derived trace IDs.
Both overloads are replaced:
- hashSpan(cat, name, hash, size) — standalone with random span_id
- hashSpan(cat, name, hash, size, parentSpanId, parentSize, flags)
— with remote parent from protobuf context propagation
Add full span name constants (tx_span::receive, tx_span::process)
to TxSpanNames.h following the ConsensusSpanNames.h pattern.

Replace thread_local mt19937 with xrpl::default_prng() for span ID

Remove the span-replacement logic in startRoundTracing() that was
discarding the hash-derived round span and replacing it with a linked
span (which gets a random trace_id). The deterministic trace_id from
the ledger hash is the key feature enabling cross-node correlation —
replacing it broke correlation on all rounds after the first.
Also: use thread_local mt19937 for hashSpan() span IDs (same fix as
phase-3 txSpan), add Doxygen to establish tracing method declarations
in Consensus.h, and update SpanGuard.h diagram with hashSpan/addEvent.

Instrument the consensus subsystem with OpenTelemetry spans covering
the full round lifecycle: round start, establish phase, proposal send,
ledger close, position updates, consensus check, accept, validation
send, and mode changes.
Key design choices adapted from the original Phase 4 implementation
to the new SpanGuard factory pattern introduced in Phase 3:
- Add SpanGuard::hashSpan() for category-gated hash-derived trace IDs
(consensus round spans share trace_id across validators via ledger hash)
- Add SpanGuard::addEvent() overload with key-value attribute pairs
(used for dispute.resolve events during position updates)
- Add ConsensusSpanNames.h with compile-time span name constants
following the colocated *SpanNames.h pattern from Phase 3
- Add consensusTraceStrategy config option ("deterministic"/"attribute")
for cross-node trace correlation strategy selection
- Use SpanGuard::linkedSpan() for follows-from relationships between
consecutive rounds and cross-thread validation spans
- Use SpanGuard::captureContext() for thread-safe context propagation
from consensus thread to jtACCEPT worker thread
Spans produced: consensus.round, consensus.proposal.send,
consensus.ledger_close, consensus.establish, consensus.update_positions,
consensus.check, consensus.accept, consensus.accept.apply,
consensus.validation.send, consensus.mode_change

is not defined, preventing a linker error if called in that path
- linkedSpan(): set kIsRootSpanKey on the StartSpanOptions parent
context so linked spans start a genuinely independent sub-tree
instead of silently becoming children of the current active span
- Telemetry::instance_: use std::atomic with acquire/release ordering
to avoid a data race between start()/stop() and factory methods
called from worker threads

Redesign SpanGuard with pimpl idiom to hide all OpenTelemetry types
from public headers. Add global Telemetry accessor so SpanGuard factory
methods work without explicit Telemetry references. Add child/linked
span creation and cross-thread context propagation. Update plan docs
to reflect macro removal in favor of SpanGuard factory pattern.

Add DiscardFlag.h and FilteringSpanProcessor references to the file
tree, key files table, and implementation summary in OpenTelemetryPlan.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add span discard mechanism that drops unwanted spans before they enter
the batch export queue, saving both network bandwidth and storage.
FilteringSpanProcessor is a custom SpanProcessor decorator that wraps
BatchSpanProcessor. SpanGuard::discard() sets a thread-local flag
(tl_discardCurrentSpan) before calling Span::End(). The OTel SDK calls
OnEnd() synchronously on the same thread, where the flag is checked and
cleared to drop the span.
New file: DiscardFlag.h — zero-dependency header for the thread-local
flag, avoiding transitive include bloat from Telemetry.h.

Add Sub-task 7.10a: Per-Validator Validation Count (Flag Ledger Window)
to the Phase 7 task list. This metric tracks how many of the last 256
ledgers each UNL validator has validated — the key participation metric
for UNL health monitoring.
Implementation plan:
- Observable gauge rippled_validator_participation with validator label
- Data from RCLValidations::getTrustedForLedger() over 256-ledger window
- Emitted at flag ledger boundaries (~15 min interval)
- Grafana table panel with threshold coloring (green/yellow/red)

Populate baselines/baseline-timings.json from the green CI run
(24906110133, commit f11ebc1253). 25/31 metrics have non-null values;
6 span.rpc.* are null due to sparse data in the 3m window.
Remove the rpc_methods section from regression-metrics.json and its
thresholds. rippled_rpc_method_duration_us_bucket is never populated
because PerfLogImp::rpcEnd never calls MetricsRegistry::recordRpcFinished
— only recordRpcStarted is wired up (Phase 9 instrumentation gap).
The span-based rpc.request/rpc.process metrics via spanmetrics already
cover RPC latency.
Two CI failures traced to root cause:
1. rippled_jobq_job_count: 0 series — StatsDGaugeImpl declared
m_dirty{false} despite the constructor comment saying "start dirty".
Gauges whose value starts and stays at 0 never emitted, so Prometheus
never scraped them. Fix: m_dirty{true} on the member initializer.
2. TX error rate 82.8% — the submitter tracked account sequences
locally, but in a multi-node consensus network other nodes' txns
advance sequences independently. After a few ledger closes the
locally-tracked sequence fell behind the ledger, producing
tefPAST_SEQ for every subsequent submission. Fix: refresh account
sequences from account_info every 10 s during the submission loop.
- capture_timings.py: fail when captured/total ratio < 50%
(--min-capture-ratio). Prevents silent pass on unreachable Prometheus.
- run-full-validation.sh: set REGRESSION_EXIT=2 on capture failure so
the final exit code reflects it. Update exit code docs in header.
- compare_to_baseline.py: extract _skip_delta helper to bring
compute_delta under 80 lines. Fix 0.0-as-falsy bug in abs_bound
resolution (use explicit None check instead of `or`). Remove dead
variable override_prefix_key.
- prom_queries.py: extract _build_simple_entries and _build_job_entries
to bring build_query_plan under 80 lines. Fix module docstring return
type example. Use aiohttp.ClientTimeout instead of bare int.
- telemetry-validation.yml: add set -euo pipefail to regression summary
step; guard jq calls with -e flag and fallback; fail on missing
baseline file; emit ::warning annotation when timings.json missing.
- baselines/README.md: document the placeholder field.
Captures per-span / per-RPC / per-job timings from Prometheus after the
workload run and diffs them against a committed baseline. Regression
requires breaching both a percentage and an absolute bound, tolerating
small-value noise. When the baseline is a placeholder, the comparator
emits the captured JSON in the exact schema for one-time paste into
baselines/baseline-timings.json, and the CI Step Summary surfaces that
block for the reviewer.
Scope: gate only — automated baseline persistence, benchmark.sh
PromQL migration, and the historical trend dashboard remain follow-ups.

This change:
* Removes a set of unnecessary brackets in the initialization of an `std::uint32_t`.
* Fixes a couple of incorrect flags (same value, just wrong variables - so no amendment needed).
This change replaces all instances of `<variable> != tesSUCCESS` with `!isTesSuccess(<variable>)` and `<variable> == tesSUCCESS` with `isTesSuccess(<variable>)`.
This change fixes delegation:
* If the Delegate object is not present, we should disallow empty permission list in DelegateSet preclaim.
* Empty permission list is only allowed to delete the existing Delegate object.
* In `doApply`, permission list being empty returns `tecINTERNAL`, which should not happen.
This change:
* Makes `addSLE` in `DIDSet` a static function, instead of a free function.
* Renames `Attestation` to `Data` everywhere (an artifact of a previous name for the field).
* Actually runs a set of tests that were not included in the `run` function of `DID_test`.
This change:
* Introduces a new helper function on `STTx`, `getFeePayer`.
* Removes the usage of `mSourceBalance` and replaces it with SLE balance lookups.
* Renames `mPriorBalance` to `preFeeBalance_`
This simplifies some of the code in the transactors and makes it a lot more readable.
Throwing exceptions from code sometime confuses ASAN, as it cannot keep track of stack frames. This change therefore adds a macro to skip instrumentation around the `Throw` function.
This change moves the sanitizer runtime options out to dedicated files, such that they can be used in multiple places (CI, local runs) without any need to rewrite them.
Per [XLS-0095](https://xls.xrpl.org/xls/XLS-0095-rename-rippled-to-xrpld.html), we are taking steps to rename ripple(d) to xrpl(d). This change modifies the system name from `rippled` to `xrpld`.
The system name is used in limited places:
* When no explicit config file is passed via the `--config` flag, then the system name is used to construct the path where the config file and database may be stored, via the `$XDG_CONFIG_HOME` and `$XDG_DATA_HOME` directories, respectively.
* It is used in the metadata and user-agent as part of RPC calls.
* It is newly used in the full version string.
ASAN wasn't able to keep track of `boost::coroutine` context switches, and would lead to many false positives being detected. By switching to `boost::coroutine2` and `ucontext`, ASAN is able to know about the context switches advertised by the `boost::fiber` class, which in turn leads to more cleaner ASAN analysis.
The `HTTPClient` class initializes a global SSL context via `initializeSSLContext()`. However, it had no way to release it, which caused memory leaks flagged by the LeakSanitizer. Multiple LSAN suppressions in the sanitizers' suppressions file were masking these leaks. Our test code also manually called `initializeSSLContext()` in each test without guaranteed cleanup on failure paths.
This change fixes these memory leaks by adding a `cleanupSSLContext()` method to properly release the global SSL context, and removes the corresponding LSAN suppressions. The change further refactors the `HTTPClient` tests to use a Google Test fixture (`HTTPClientTest`) that manages the SSL context lifecycle via RAII (SetUp/TearDown), making it impossible for tests to leak the context.
This change deletes the `SecretKey` equality/inequality operators from the public library header and moves the comparison logic into test-only code.
Specifically, the `operator==` and `operator!=` free functions on `SecretKey` have been removed from `include/xrpl/protocol/SecretKey.h` and have been replaced with explicitly deleted member functions to prevent accidental use in production code. A named `test::equal()` helper has also been added in `src/test/unit_test/utils.h` for test assertions that need to compare secret keys.
This change removes an unnecessary newline in a logging statement. Namely, `std::endl` is unneeded in `JLOG`, since it automatically places a newline at the end of the string.
This change enforces a maximum length of 63 characters on feature names, as well as not permitting an exactly 32 character long feature name to avoid confusion with those that use a `uint256` hex representation, as that is an alternative way to specify a feature. This change further prevents the use of Unicode characters in feature names, because some can be confused with regular ASCII characters despite being valid in identifiers.
The `setFieldU32` call is currently used to set the credential's expiry using a `getFieldU32` call to obtain the expiration time. However, that value was already obtained previously and can thus be reused.
DID, Escrows, PaymentChannels, and Credentials previously contained multiple unrelated transactor classes in a single header/implementation pair. This change splits each into one class per file, following the same pattern established by the rest of the codebase.
Now that prefixes in PR titles are being validated as part of CI, the "Type of Change" section in the PR template is no longer needed. The prefixes and descriptions in the `CONTRIBUTING.md` file have been updated to reflect the currently supported list.
Subscribe tests have a problem that there is no way to synchronize application running in background threads and test threads. Threads are communicating via websocket messages. When the code is compiled in debug mode with code coverage enabled it executes quite slow, so receiving websocket messages by the client in subscribe tests may time out.
This change does 2 things to fix the problem:
* Increases timeout for receiving a websocket message.
* Decreases the number of tests running in parallel.
While testing the fix for subscribe test another flaky test in ledger replay was found, which has also been addressed.
The refs as previously used pointed to the source branch, not the target branch. However, determining the target branch is different depending on the GitHub event. The pull request logic was incorrect and needed to be fixed, and the logic inside the workflow could be simplified. Both modifications have been made in this commit.
This change reorganizes the `tx/transactors` directory for consistency and discoverability. There are no behavioral changes, this is a pure refactor. Underscores were chosen as the way to separate multi-words as this is the more popular option in C++ projects.
Specific changes:
- Rename all subdirectories to lowercase/snake_case (`AMM` → `amm`, `Check` → `check`, `NFT` → `nft`, `PermissionedDomain` → `permissioned_domain`, etc.)
- Merge `AMM/` and `Offer/` into `dex/`, including `PermissionedDEXHelpers`
- Rename `MPT/` → `token/`, absorbing `SetTrust` and `Clawback`
- Move top-level transactors into named groups: `account/`, `bridge/`, `credentials/`, `did/`, `escrow/`, `oracle/`, `payment/`, `payment_channel/`, `system/`
- Update all include paths across the codebase and `transactions.macro`
The existing code added the git commit info (`GIT_COMMIT_HASH` and `GIT_BRANCH`) to every file, which was a problem for leveraging `ccache` to cache build objects. This change adds a separate C++ file from where these compile-time variables are propagated to wherever they are needed. A new CMake file is added to set the commit info if the `git` binary is available.
When `gateway_balances` gets called on an account that is involved in the `EscrowCreate` transaction (with MPT being escrowed), the method returns internal error. This change fixes this case by excluding the MPT type when totaling escrow amount.
The `Subscribe` tests were flaky, because each test performs some operations (e.g. sends transactions) and waits for messages to appear in subscription with a 100ms timeout. If tests are slow (e.g. compiled in debug mode or a slow machine) then some of them could fail. This change adds an attempt to synchronize the background Env's thread and the test's thread by ensuring that all the scheduled operations are started before the test's thread starts to wait for a websocket message. This is done by limiting I/O threads of the app inside Env to 1 and adding a synchronization barrier after closing the ledger.
The invariant check system had grown into a single monolithic file pair containing 24 invariant checker classes. The large `InvariantCheck.cpp` file was a frequent source of merge conflicts and difficult to navigate. This refactoring improves maintainability and readability with zero behavioral changes.
In particular, this change:
- Splits `InvariantCheck.h` and `InvariantCheck.cpp` into 10 focused header/source pairs organized by domain under a new `invariants/` subdirectory.
- Extracts the shared `Privilege` enum and `hasPrivilege()` function into a dedicated `InvariantCheckPrivilege.h` header, so domain-specific files can reference them independently.
This change enables all clang-tidy checks that are already passing. It also modifies the clang-tidy CI job, so it runs against all files if .clang-tidy changed.
This change replaces `void const*` by `uint256 const&` for database fetches.
Object hashes are expressed using the `uint256` data type, and are converted to `void *` when calling the `fetch` or `fetchBatch` functions. However, in these fetch functions they are converted back to `uint256`, making the conversion process unnecessary. In a few cases the underlying pointer is needed, but that can then be easy obtained via `[hash variable].data()`.
Updates XRPLF/actions prepare-runner to version 2cbf48101 which fixes
pip upgrade failures on macOS runners with Homebrew-managed Python.
* This commit was cherry-picked from "release-3.1", but ended up empty
because the changes are already present. It is included only for
accounting - to indicate that all changes/commits from the previous
release will be in the next one.
For coverage builds, we try to link against the `gcov` library (specific to the environment). But as macOS doesn't have this library and thus doesn't have the coverage tools to generate reports, the coverage builds on that platform were failing on linking.
We actually don't need to explicitly force this linking, as the `CodeCoverage` file already has correct detection logic (currently on lines 177-193), which is invoked when the `--coverage` flag is provided:
* AppleClang: Uses `xcrun -f llvm-cov` to set `GCOV_TOOL="llvm-cov gcov"`.
* Clang: Finds `llvm-cov` to set `GCOV_TOOL="llvm-cov gcov"`.
* GCC: Finds `gcov` to set `GCOV_TOOL="gcov"`.
The `GCOV_TOOL` is then passed to `gcovr` on line 416, so the correct tool is used for processing coverage data.
This change therefore removes the `gcov` suffix from lines 473 and 475 in the `CodeCoverage.cmake` file.
The rdb module was not properly designed, which is fixed in this change. The module had three classes:
1) The abstract class `RelationalDB`.
2) The abstract class `SQLiteDatabase`, which inherited from `RelationalDB` and added some pure virtual methods.
3) The concrete class `SQLiteDatabaseImp`, which inherited from `SQLiteDatabase` and implemented all methods.
The updated code simplifies this as follows:
* The `SQLiteDatabaseImp` has become `SQLiteDatabase`, and
* The former `SQLiteDatabase `has merged with `RelationalDatabase`.
This change modularizes the `WalletDB` and `Manifest`. Note that the wallet db has nothing to do with account wallets and it stores node configuration, which is why it depends on the manifest code.
This change removes the cache in `DatabaseNodeImp` and simplifies the caching logic in `SHAMapStoreImp`. As NuDB and RocksDB internally already use caches, additional caches in the code are not very valuable or may even be unnecessary, as also confirmed during preliminary performance analyses.
In certain cases, such as when modifying headers used by many compilation units, performing a unity build is slower than when performing a regular build with `ccache` enabled. There is also a benefit to a unity build in that it can detect things such as macro redefinitions within the group of files that are compiled together as a unit. This change therefore restores the ability to perform unity builds. However, instead of running every configuration with and without unity enabled, it is now only enabled for a single configuration to maintain lower computational use.
As part of restoring the code, it became clear that currently two configurations have coverage enabled, since the check doesn't focus specifically on Debian Bookworm so it also applies to Debian Trixie. This has been fixed too in this change.
The `ManifestCache::applyManifest` function was returning early without incrementing `seq_`. `OverlayImpl `uses this sequence to identify/invalidate a cached `TMManifests` message, which is exchanged with peers on connection. Depending on network size, startup sequencing, and topology, this can cause syncing issues. This change therefore increments `seq_` when a new manifest is accepted.
Unity builds were intended to speed up builds, by bundling multiple files into compilation units. However, now that ccache is available on all platforms, there is no need for unity builds anymore, as ccache stores compiled individual build objects for reuse. This change therefore removes the ability to make unity builds.
Currently we're passing the `Application` object around, whereby the `Application` class acts more like a service registry that gives other classes access to other services. In order to allow modularization, we should replace `Application` with a service registry class so that modules depending on `Application` for other services can be moved easily. This change adds the `ServiceRegistry` class.
This change introduces the `fixExpiredNFTokenOfferRemoval` amendment that allows expired offers to pass through `preclaim()` and be deleted in `doApply()`, following the same pattern used for expired credentials.
This change adds the project configuration directory to `.gitignore` for the `zed` editor.
As per the [documentation](https://zed.dev/docs/remote-development?highlight=.zed#zed-settings), the project configuration files are stored in the `.zed` directory at the project root dir.
This change cleans up the `API-CHANGELOG.md` file. It moves the version-specific documentation to other files and fleshes out the changelog with all the API-related changes in each version.
When support was added for `xrpld.cfg` in addition to `rippled.cfg` in https://github.com/XRPLF/rippled/pull/6098, as part of an effort to rename occurrences of ripple(d) to xrpl(d), the clearing and creation of the data directory were modified for what, at the time, seemed to result in an equivalent code flow. This has turned out to not be true, which is why this change restores two modifications to `Config.cpp` that currently break running the binary in standalone mode.
This change adds `cmake-format` as. a pre-commit hook. The style file closely matches that in Clio, and they will be made to be equivalent over time. For now, some files have been excluded, as those need some manual adjustments, which will be done in future changes.
This change makes the `read` function call in `handleConnection` async, adds a new class `TestSink` to help debugging, and adds a new target `xrpl.tests.helpers` to put the helper class in.
To allow developers to consume the latest unstable and (near-)stable versions of our `xrpl` Conan recipe, we should export and upload it whenever a push occurs to the corresponding branch or a release tag has been created. This way, developers do not have to figure out themselves what the most recent shortened commit hash was to determine the latest unstable recipe version (e.g. `3.2.0-b0+a1b2c3d`) or what the most recent release (candidate) was to determine the latest (near-)stable recipe version (e.g. `3.1.0-rc2`).
Now, pushes to the `develop` branch will produce the `develop` recipe version, pushes to the `release` branch will produce the `rc` recipe version, and creation of versioned tags will produce the `release` recipe version.
This change replaces the mutex `stoppingMutex_`, the `atomic_bool` variable `isTimeToStop`, and the conditional variable `stoppingCondition_` with an `atomic_flag` variable.
When `xrpld` is running the embedded tests as a child process, it has a control thread (the app bundle thread) that starts the application, and an application thread (the thread that executes `app_->run()`). Due to the relaxed memory ordering on ARM, it's not guaranteed that the application thread can see the change of the value resulting from the `isTimeToStop.exchange(true)` call before it is notified by `stoppingCondition_.notify_all()`, even though they do happen in the right order in the app bundle thread in `ApplicationImp::signalStop`. We therefore often get into the situation where `isTimeToStop` is `true`, but the application thread is waiting for `stoppingCondition_` to notify, because the app bundle thread may have already notified before the application thread actually starts waiting.
Switching to a single `atomic_flag` variable makes sure that there's only one synchronisation object and then the memory order guarantee provided by c++ can make sure that `notify_all` gets synchronised after `test_and_set` does.
Fixing this issue will stop the unit tests hanging forever and then we should see less (or hopefully no) time out errors in daily github action runs
Since the minimum Clang version we support is 16, the checks for version < 15 are no longer necessary. This change therefore removes the macros checking if the clang version is < 15 and simplifies uses of `std::source_location`.
The `upload-conan-deps` workflow that's triggered on push is supposed to upload the Conan dependencies to our remote, so future PR commits can pull those dependencies from the remote. However, as the `sanitize` argument is missing, it was building different dependencies than what the PRs are building for the asan/tsan/ubsan job, so the latter would not find anything in the remote that they could use. This change sets the missing `sanitizers` input variable when running the `build-deps` action.
Separately, the `setup-conan` action showed the default profile, while we are using the `ci` profile. To ensure the profile is correctly printed when sanitizers are enabled, the environment variable the profile uses is set before calling the action.
The export and upload steps were initially in a separate action, where GitHub Actions does not support the `secrets` keyword, but only `inputs` for the credentials. After they were moved to a reusable workflow, only part of the references to the credentials were updated. This change correctly references to the Conan credentials via `secrets` instead of `inputs`.
By default the Conan recipe extracts the version from `BuildInfo.cpp`, but in some of the cases we want to upload a recipe with a suffix derived from the commit hash. This currently then results in the uploading to fail, since there is a version mismatch.
Here we explicitly set the version, and then simplify the steps in the upload workflow since we now need the recipe name (embedded within the conanfile.py but also needed when uploading), the recipe version, and the recipe ref (name/version).
Conan recipes use semantic versioning, and since our version already contains a hyphen the second hyphen causes Conan to ignore it. The plus sign is a valid separator we can use instead, so this change uses a `+` to separate a version suffix (commit hash) instead of a `-`.
There were a few uninitialized variables in CMake files. This change will make sure we always check if a variable has been initialized before using them, or in come cases initialize them by default. This change will raise an error on CI if a developer introduced an uninitialized variable in CMake files.
This change continues the thread naming work from #5691 and #5758, which enables more useful lock contention profiling by ensuring threads/jobs have short, stable, human-readable names (rather than being truncated/failing due to OS limits). This changes diagnostic naming only (thread names and job/load-event labels), not behavior.
Specific modifications are:
* Shortens all thread/job names used with `beast::setCurrentThreadName`, so the effective Linux thread name stays within the 15-character limit.
* Removes per-ledger sequence numbers from job/thread names to avoid long labels. This improves aggregation in lock contention profiling for short-lived job executions.
The Ripple Bug Bounty program recently changed the public keys that security researchers can use to encrypt vulnerabilities and messages for submission to the program. This information was updated on https://ripple.com/legal/bug-bounty/ and this PR updates the `SECURITY.md` to align.
During several iterations of development of https://github.com/XRPLF/rippled/pull/6235, the commit hash was supposed to be moved into the `run:` statement, but it slipped through the cracks and did not get added. This change adds the commit hash as suffix to the Conan recipe version.
The `Number.h` header file now has `std::reference_wrapper` from `<functional>`, but the include is missing, causing downstream build problems. This change adds the header.
This change uploads the `libxrpl` library as a Conan recipe to our remote when (i) merging into the `develop` branch, (ii) committing to a PR that targets a `release*` branch, and (iii) a versioned tag is applied. Clio is only notified in the second case. The user and channel are no longer used when uploading the recipe.
Specific changes are:
* A `generate-version` action is added, which extracts the build version from `BuildInfo.cpp` and appends the short 7-character commit hash to it for merges into the `develop` branch and for commits to a PR that targets a `release*` branch. When a tag is applied, however, the tag itself is used as the version. This functionality has been turned into a separate action as we will use the same versioning logic for creating .rpm and .deb packages, as well as Docker images.
* An `upload-recipe` action is added, which calls the `generate-version` action and further handles the uploading of the recipe to Conan.
* This action is called by both the `on-pr` and `on-trigger` workflows, and a new `on-tag` workflow.
The reason for this change is that we have downstream uses for the `libxrpl` library, but currently only upload the recipe to check for compatibility with Clio when making commits to a PR that targets the release branch.
`PeerImp` processes `TMGetObjectByHash` queries with an unbounded per-request loop, which performs a `NodeStore` fetch and then appends retrieved data to the reply for each queried object without a local count cap or reply-byte budget. However, the `Nodestore` fetches are expensive when high in numbers, which might slow down the process overall. Hence this code change adds an upper cap on the response size.
This change removes the `master` branch as a trigger for the CI pipelines, and updates comments accordingly. It also fixes the pre-commit workflow, so it will run on all release branches.
These "fixed location" objects can be found in multiple ways:
1. The lookup parameters use the same format as other ledger objects, but the only valid value is true or the valid index of the object:
- Amendments: "amendments" : true
- FeeSettings: "fee" : true
- NegativeUNL: "nunl" : true
- LedgerHashes: "hashes" : true (For the "short" list. See below.)
2. With RPC API >= 3, using special case values to "index", such as "index" : "amendments". Uses the same names as above. Note that for "hashes", this option will only return the recent ledger hashes / "short" skip list.
3. LedgerHashes has two types: "short", which stores recent ledger hashes, and "long", which stores the flag ledger hashes for a particular ledger range.
- To find a "long" LedgerHashes object, request '"hashes" : <ledger sequence>'. <ledger sequence> must be a number that evaluates to an unsigned integer.
- To find the "short" LedgerHashes object, request "hashes": true as with the other fixed objects.
The following queries are all functionally equivalent:
- "amendments" : true
- "index" : "amendments" (API >=3 only)
- "amendments" : "7DB0788C020F02780A673DC74757F23823FA3014C1866E72CC4CD8B226CD6EF4"
- "index" : "7DB0788C020F02780A673DC74757F23823FA3014C1866E72CC4CD8B226CD6EF4"
Finally, whether the object is found or not, if a valid index is computed, that index will be returned. This can be used to confirm the query was valid, or to save the index for future use.
This change adds support for sanitizer build options in CI builds workflow. Currently `asan+ubsan` is enabled, while `tsan+ubsan` is left disabled as more changes are required.
The word `failed` in the test case makes it hard to search through the test logs when an actual test failure occurs, so this change renames the word to just `fail` instead.
- Refactor Number internals away from int64 to uint64 & a sign flag
- ctors and accessors use `rep`. Very few things expose
`internalrep`.
- An exception is "unchecked" and the new "normalized", which explicitly
take an internalrep. But with those special control flags, it's easier
to distinguish and control when they are used.
- For now, skip the larger mantissas in AMM transactions and tests
- Remove trailing zeros from scientific notation Number strings
- Update tests. This has the happy side effect of making some of the string
representations _more_ consistent between the small and large
mantissa ranges.
- Add semi-automatic rounding of STNumbers based on Asset types
- Create a new SField metadata enum, sMD_NeedsAsset, which indicates
the field should be associated with an Asset so it can be rounded.
- Add a new STTakesAsset intermediate class to handle the Asset
association to a derived ST class. Currently only used in STNumber,
but could be used by other types in the future.
- Add "associateAsset" which takes an SLE and an Asset, finds the
sMD_NeedsAsset fields, and associates the Asset to them. In the case
of STNumber, that both stores the Asset, and rounds the value
immediately.
- Transactors only need to add a call to associateAsset _after_ all of
the STNumbers have been set. Unfortunately, the inner workings of
STObject do not do the association correctly with uninitialized
fields.
- When serializing an STNumber that has an Asset, round it before
serializing.
- Add an override of roundToAsset, which rounds a Number value in place
to an Asset, but without any additional scale.
- Update and fix a bunch of Loan-related tests to accommodate the
expanded Number class.

- Spec: XLS-66
Fix overpayment asserts (#6084)
MPTTester::operator() parameter should be std::int64_t
- Originally defined as uint64_t, but the testIssuerLoan() test called
it with a negative number, causing an overflow to a very large number
that in some circumstances could be silently cast back to an int64_t,
but might not be. I believe this is UB, and we don't want to rely on
that.
Review feedback from @Tapanito: overpayment value change
- In overpayment results, the management fee was being calculated twice:
once as part of the value change, and as part of the fees paid.
Exclude it from the value change.
Fix Overpayment Calculation (#6087)
- Adds additional unit tests to cover math calculations.
- Removes unused methods.
Review feedback from @shawnxie999: even more rounding
- Round the initial total value computation upward, unless there is
0-interest.
- Rename getVaultScale to getAssetsTotalScale, and convert one incorrect
computation to use it.
- Use adjustImpreciseNumber for LossUnrealized.
- Add some logging to computeLoanProperties.
Fix LoanBrokerSet debtMaximum limits (#6116)
Fix some minor bugs in Lending Protocol (#6101)
- add nodiscard to unimpairLoan, and check result in LoanPay
- add a check to verify that issuer exists
- improve LoanManage error code for dust amounts

Add a few minor changes (#6158)
- Updates or fixes a couple of things I noticed while reviewing changes
to the spec.
- Rename sfPreviousPaymentDate to sfPreviousPaymentDueDate.
- Make the vault asset cap check added in #6124 a little more robust:
1. Check in preflight if the vault is _already_ over the limit.
2. Prevent overflow when checking with the loan value. (Subtract
instead of adding, in case the values are near maxint. Both return
the same result. Also add a unit test so each case is covered.
Add minimum grace period validation (#6133)
Fix bugs: frozen pseudo-account, and FLC cutoff (#6170)

This change removes unnecessary version numbers in the OpenSSL and Boost `find_package` CMake statements. An unnecessary OpenSSL definition is removed, while Conan options for SSL are updated to disable insecure ciphers. Moreover, the statements are now ordered alphabetically and more logically.
- Introduces amendment `fixBatchInnerSigs`
- Update Batch unit tests
- Fix all the Env instantiations to _use_ the "features" parameter.
- testInnerSubmitRPC runs with Batch enabled and disabled.
- Add a test to testInnerSubmitRPC for a correctly signed tx incorrectly
using the tfInnerBatchTxn flag.
- Generalize the submitAndValidate lambda in testInnerSubmitRPC.
- With the fix amendment, a transaction never reaches the transaction
engine (Transactor and derived classes.)
- Test submitting a pseudo-transaction. Stopped before reaching the
transaction engine, but with different errors.
- The tests verify that without the amendment, a transaction with
tfInnerBatchTxn is immediately rejected. Without the amendment, things
are safe. The amendment just makes things safer and more future-proof.
- Adds a mechanism for the vault owner to burn user shares when the vault is stuck. If the Vault has 0 AssetsAvailable and Total, the owner may submit a VaultClawback to reclaim the worthless fees, and thus allow the Vault to be deleted. The Amount must be left off (unless the owner is the asset issuer), specified as 0 Shares, or specified as the number of Shares held.
This change:
* Truncates thread names if more than 15 chars with `snprintf`.
* Adds warnings for truncated thread names if `-DTRUNCATED_THREAD_NAME_LOGS=ON`.
* Add a static assert for string literals to stop compiling if > 15 chars.
* Shortens `Resource::Manager` to `Resource::Mngr` to fix the static assert failure.
* Updates `CurrentThreadName_test` unit test specifically for Linux to verify truncation.
This change updates the XRPLF pre-commit workflow and prepare-runner action to their latest versions. For naming consistency the prepare-runner action changed the disable_ccache variable into enable_ccache, which matches our naming.
This change fixes the last of the spelling issues, and enables the pre-commit (and CI) check for spelling. There are no functionality changes, but it does rename some enum values.
Right now, each pipeline invocation builds the source code from scratch. Although compiled Conan dependencies are cached in a remote server, the source build objects are not. We are able to further speed up our builds by leveraging `ccache`. This change enables caching of build objects using `ccache` on Linux, macOS, and Windows.
This change adds some basic tests for all the `ledger_entry` helper functions, so each ledger entry type is covered. There are further some minor refactors in `parseAMM` to provide better error messages. Finally, to improve readability, alphabetization was applied in the helper functions.
This change renames all occurrences of `rippled.cfg` to `xrpld.cfg`. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts. For the time being it maintains support for `rippled.cfg` as config file, if `xrpld.cfg` does not exist.
This change modifies the build directory structure from `build/build/xxx` or `.build/build/xxx` to just `build/xxx`. Namely, the `conanfile.py` has the CMake generators build directory hardcoded to `build/generators`. We may as well leverage the top-level build directory without introducing another layer of directory nesting.
`Json::Object` and related objects are not used at all, so this change removes `include/xrpl/json/Object.h` and all downstream files. There are a number of minor downstream changes as well.
Full list of deleted classes and functions:
* `Json::Collections`
* `Json::Object`
* `Json::Array`
* `Json::WriterObject`
* `Json::setArray`
* `Json::addObject`
* `Json::appendArray`
* `Json::appendObject`
The last helper function, `copyFrom`, seemed a bit more complex and was actually used in a few places, so it was moved to `LedgerToJson.h` instead of deleting it.
The latest update to `cleanup-workspace`, `get-nproc`, and `prepare-runner` moved the action to the repository root directory, and also includes some ccache changes. In response, this change updates the various shared actions to the latest commit hash.
This change renames all occurrences of `namespace ripple` and `ripple::` to `namespace xrpl` and `xrpl::`, respectively, as well as the names of test suites. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
Per [XLS-0095](https://xls.xrpl.org/xls/XLS-0095-rename-rippled-to-xrpld.html), we are taking steps to rename ripple(d) to xrpl(d).
This change modifies the binary name from `rippled` to `xrpld`, and creates a symlink named `rippled` that points to the `xrpld` binary.
Note that https://github.com/XRPLF/rippled/pull/5975 renamed any references to `rippled` in the CMake files and their contents, but explicitly maintained the `rippled` binary name by adding an exception. This change now undoes this exception and adds an explicit symlink instead.
This change renames all the `info()` functions to `header()`, since they return `LedgerHeader` structs. It also renames the underlying variables from `info_` to `header_`.
This PR renames `LedgerInfo` to `LedgerHeader`. Namely, `LedgerInfo` was already an alias for `LedgerHeader`, and the comments next to the alias suggested that it would make sense to rename it, since that makes it clearer what it is.
This PR cleans up `RPCHelpers.h` and `RPCHelpers.cpp`. It splits out all the fetch-ledger functions to a new set of files, `RPCLedgerHelpers.h`/`RPCLedgerHelpers.cpp`, and moves the general-API functions to `ApiVersion.h`. There is no functionality change.
The .gitignore and .gitattributes files contain references to files and directories that the current build no longer produces, so this change removes obsolete entries in these files, and does some general reorganizing of the remaining entries.
This change updates the secp256k1 recipe that defines the SECP256K1_STATIC, so it no longer needs to be defined in the code here. Running the Conan update script also updated two other recipes in the lock file.
This PR updates protobuf and grpc to their latest versions. The latest protobuf version no longer requires patches, so we can use it directly from the official Conan Center Index, while the latest grpc still needed a patch, which was added to our own Conan Center Index fork in XRPLF/conan-center-index#8.
This change substitutes the secp256k1 source code copy by the Conan recipe added in XRPLF/conan-center-index#24, which updates the version of the library to 0.7.0.
- Spec: XLS-66
- Introduces amendment "LendingProtocol", but leaves it UNSUPPORTED to
allow for standalone testing, future development work, and potential
bug fixes.
- AccountInfo RPC will indicate the type of pseudo-account when
appropriate.
- Refactors and improves several existing classes and functional areas,
including Number, STAmount, STObject, json_value, Asset, directory
handling, View helper functions, and unit test helpers.
This change moves the lockfile instructions into a script, and instead of removing packages it sets the Conan home directory to a temporary directory.
There are several advantages, such as:
* Not affecting the user's Conan home directory, so there is no need to remove packages.
* Only the script needs to be run, rather than several commands.
This change updates the instructions for how to generate a Conan lockfile that is compatible with Linux, macOS, and Windows.
Whenever Conan dependencies change, the Conan lock file needs to be regenerated. However, different OSes have slightly different requirements, and thus require slightly different dependencies. Luckily a single `conan.lock` file can be used, as long as the union of dependencies is included.
The current instructions in the `BUILD.md` file are insufficient to regenerate the lock file such that it is compatible with all OSes, which this change addresses. The three profiles contain the bare minimum needed to generate the lockfile; it does not particularly matter whether the build type is Debug or Release, for instance.
This change triggers the Clio pipeline on PRs that target any of the `release*` branches (in addition to the `master` branch), as opposed to only the `release` branch.
If the config disables SQL db usage, such as a validator:
```
[ledger_tx_tables]
use_tx_tables = 0
```
then the pointer to DB engine is null, but it was still resolved during startup. Although it didn't crash in Release mode, possibly due to the compiler optimizing it away, it did crash in Debug mode. This change explicitly checks for the validity of the pointer and generates a runtime error if not set.
The `ledger_entry` and `deposit_preauth` requests require an array of credentials. However, the array size is not checked before is gets processing. This fix adds checks and return errors in case array size is too big.
This PR splits `RPCHelpers.h` into two files, by moving out all the ledger-fetching-related functions into a separate file, `RPCLedgerHelpers.h`. It also moves `getAccountObjects` to `AccountObjects.h`, since it is only used in that one place.
Technically b0 is not a release, so no "release" prefix here. It marks the point at which we moved the preceding release (3.0.0 in this case) from Beta to Release Candidate.
This change fixes floating point errors in conversion of shares to assets and other way, used in `VaultDeposit`, `VaultWithdraw` and `VaultClawback`. In the floating point calculations the division introduces a larger error than multiplication. If we do division first, then the error introduced will be increased by the multiplication that follows, which is therefore the wrong order to perform these two operations. This change flips the order of arithmetic operations, which minimizes the error.
Rather than having a single `XRPL_RETIRE` macro that applies to both feature and fix amendments, this change replaces it by new `XRPL_RETIRE_FIX` and `XRPL_RETIRE_FEATURE` macros that avoids confusion between whether to prefix the amendment name with `feature` or `fix`.
This updates the CI image hashes after following change: https://github.com/XRPLF/ci/pull/81. And, since we use latest Conan, we can have `conan.lock` with a newline at the end, and we don't need to exclude it from `pre-commit` hooks any longer.
This change fixes JSON parsing of negative `int` input in `STNumber` and `STAmount`. The conversion of JSON to `STNumber` or `STAmount` may trigger a condition where we negate smallest possible `int` value, which is undefined behaviour. We use a temporary storage as `int64_t` to avoid this bug. Note that this only affects RPC, because we do not parse JSON in the protocol layer, and hence no amendment is needed.
This change removes unused definitions from the CMake files, moves variable definitions from `XrplSanity` to `XrplSettings` where they better belong, and updates the minimum GCC and Clang versions to match what we actually minimally support.
This change unifies the build and test jobs into a single job, and adds `ctest` to coverage reporting.
The mechanics of coverage reporting is slightly complex and most of it is encapsulated in the `coverage` target. The status quo way of preparing coverage reports involves running a single target `cmake --build . --target coverage`, which does three things:
* Build the `rippled` binary (via target dependency)
* Prepare coverage reports:
* Run `./rippled -u` unit tests.
* Gather test output and build reports.
This makes it awkward to add an additional `ctest` step between build and coverage reporting steps. The better solution is to split `coverage` target into separate build, followed by `ctest`, followed by test generation. Luckily, the `coverage` target has been designed specifically to support such case; it does not need to build `rippled`, it's just a dependency. Similarly it allows additional tests to be run before gathering test outputs; in principle we could even strip it from running tests and run them separately instead. This means we can keep build, `ctest` and generation of coverage reports as separate steps, as long as the state of build directory is fully (including file timestamps, additional coverage files etc.) preserved between the steps. This means that in order to run `ctest` for coverage reporting we need to integrate build and test into a single job, which this change does.
As part of renaming ripple(d) to xrpl(d), the xrpld symlink was made to point to itself instead of to the rippled binary. This change fixes the symlink.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
This change updates the CMake files and definitions therein, plus a handful of related modifications. Specifically, the compiler files are renamed from `RippleXXX.cmake` or `RippledXXX.cmake` to `XrplXXX.cmake`, and any references to `ripple` and `rippled` (with or without capital letters) are renamed to `xrpl` and `xrpld`, respectively. The name of the binary, currently `rippled`, remains unchanged and will be updated in a separate PR. This change is purely cosmetic and does not affect the functioning of the binary.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
This change specifically removes all copyright notices referencing Ripple, XRPLF, and certain affiliated contributors upon mutual agreement, so the notice in the LICENSE.md file applies throughout. Copyright notices referencing external contributions remain as-is. Duplicate verbiage is also removed.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
C++ include guards are used to prevent the contents of a header file from being included multiple times in a single compilation unit. This change renames all `RIPPLE_` and `RIPPLED_` definitions, primarily include guards, to `XRPL_`. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
Amendments activated for more than 2 years can be retired, and obsolete retirements that were never activated can also be removed after 2 years. This change retires the NonFungibleTokensV1_1, fixNonFungibleTokensV1_2, and fixNFTokenRemint amendments, and removes the NonFungibleTokensV1, fixNFTokenNegOffer, and fixNFTokenDirV1 amendments.
To debug test failures we would like to use `netstat`, but that package wasn't installed yet in the CI images. This change uses the new CI images created by https://github.com/XRPLF/ci/pull/79.
This change:
* Simplifies the `TxMeta` constructors - both were setting the same set of fields, and to make it harder for future bugs to arise and keep the code DRY, we can combine those into one helper function.
* Removes an unused constructor.
* Renames the variables to avoid Hungarian naming.
* Removes a bunch of now-unnecessary helper functions.
This change introduces the `featurePermissionDelegationV1_1` amendment, which is designed to supersede both `featurePermissionDelegation` and `fixDelegateV1_1 amendments, which should be considered deprecated. The `checkPermission` function will now return `terNO_DELEGATE_PERMISSION` when a delegate transaction lacks the necessary permissions.
This change introduces the `fixDirectoryLimit` amendment to remove the directory pages limit. We found that the directory size limit is easier to hit than originally assumed, and there is no good reason to keep this limit, since the object reserve provides the necessary incentive to avoid creating unnecessary objects on the ledger.
Field `sfSubjectNode` is not populated by `CredentialCreate` in self-issued credentials. Rather than fixup the Credentials already on the ledger, we can in this case safely change the object template for this field from `soeREQUIRED` to `soeOPTIONAL`.
- Restructures `STTx` signature checking code to be able to handle
a `sigObject`, which may be the full transaction, or may be an object
field containing a separate signature. Either way, the `sigObject` can
be a single- or multi-sign signature.
- This is distinct from 550f90a75e (#5594), which changed the check in
Transactor, which validates whether a given account is allowed to sign
for the given transaction. This cryptographically checks the signature
validity.
This change adds an extra step to the CI test job that outputs network info, which may allow us to confirm whether random test failures are caused by port exhaustion.
We are on an amendment retiring spree, but each change results in conflicts in `features.macro` because currently they all add the retired amendment to the end of the list. By sorting the list the number of conflicts should be reduced, making it easier to merge them.

To protect the identity of UNL validators, the IP addresses are redacted from the log messages sent to the common Grafana instance. However, without such identifying information it is challenging to debug issues. This change adds a node's public key to logs to improve our ability to debug issues.

There are separate steps for logging into Conan and uploading packages. However, at the moment sometimes the login step is executed even though no packages will be uploaded. The condition for performing both steps should be the same.

This change fixes the `account_tx` RPC method to properly validate malformed limit parameter values. Previously, invalid values like `0`, `1.2`, `"10"`, `true`, `false`, `-1`, `[]`, `{}`, etc. were either accepted without errors or caused internal errors. Now all malformed values correctly return the `invalidParams` error.

As XRPL network demand grows and ledger sizes increase, the default 4K NuDB block size becomes a performance bottleneck, especially on high-performance storage systems. Modern SSDs and enterprise storage often perform better with larger block sizes, but rippled previously had no way to configure this parameter. This change therefore implements configurable NuDB block size support, allowing operators to optimize storage performance based on their hardware configuration. The feature adds a new `nudb_block_size` configuration parameter that enables block sizes from 4K to 32K bytes, with comprehensive validation and backward compatibility.
Specific changes are:
- Implements `parseBlockSize()` function with validation.
- Adds `nudb_block_size` configuration parameter.
- Supports block sizes from 4K to 32K (power of 2).
- Adds comprehensive logging and error handling.
- Maintains backward compatibility with 4K default.
- Adds unit tests for block size validation.
- Updates configuration documentation with performance guidance.
- Marks feature as experimental.
- Applies code formatting fixes.

Similarly to other transaction typed that can create a trust line or MPToken for the transaction submitter (e.g. CashCheck #5285, EscrowFinish #5185 ), VaultWithdraw should enforce reserve before creating a new object. Additionally, the lsfRequireDestTag account flag should be enforced for the transaction submitter.

This change sanitizes inputs by setting them as environment variables, and adjusts the number of CPUs used for building. Namely, GitHub inputs should be sanitized, per recommendation by Semgrep, as using them directly poses a security risk. A recent change further overrode the global configuration by having builds use all cores, but as we have noticed an increased number of job cancelation this change updates it to use all cores less one.

This change excludes from Codecov unreachable/difficult-to-test transaction code (such as `tecINTERNAL`) and old code (from amendments that have been enabled for a long time that are only around for ledger replay reasons). This removes about 200 lines of misses and increases the Codecov coverage by 0.3% (79.2% to 79.5%).
This change adds a wildcard to the release branch in the CI pipeline spec. Namely, after adopting an improved release process, with release branches that now look like release-X.Y, the trigger pipeline was no longer running as it only searched for an exact match to release.
This change downgrades OpenSSL 3.6.0 to 3.5.4. To avoid potential zero-day issues in a new major version of OpenSSL, 3.6.0, it is safer to stick with 3.5.4. While 3.6.0 has some nice new features, such as improved SHA512 hashing, it also introduces new features that could contain bugs. In contrast, 3.5.4 has seen quite a few bug fixes over 3.5.0 and has been used in the wild for a while now.
This change fixes a release build error with GCC 15.2.
The `fields` variable is only used in `XRPL_ASSERT`, which evaluates to nothing in a Release build, leaving the variable unused. This change silences the build warning.

This change uses the new RHEL 9 and 10 images to build and test the binary, and adds support for having different Docker image SHAs per distro-compiler combination.
Instead of supporting RHEL each minor version, we are simplifying our pipelines by only supporting RHEL major versions. Our CI Docker images have already been updated accordingly, and we recently added support for RHEL 10 as well. Up until now, the CI Docker images had all been rebuilt at the same time, but that is not necessarily true as the most recent push to the CI repo has shown where the RHEL images now have a different SHA than the Debian and Ubuntu ones.

* Restructures Transactor signature checking code to be able to handle a `sigObject`, which may be the full transaction, or may be an object field containing a separate signature. Either way, the `sigObject` can be a single- or multi-sign signature.
* Restructures `Transactor::preflight` to create several functions that will remove the need for error-prone boilerplate code in derived classes' implementations of `preflight`.
This change adds `STInt32` as a new `SType` under the `STInteger` umbrella, with `SType` value `12`. This is the first and only `STInteger` type that supports negative values.
This change adds more comprehensive tests for the `FeeVote` module, which previously only checked the basics, and not the more comprehensive flows in that class.
This change makes the regex in `HttpClient.cpp` that matches the content-length http header case insensitive to improve compatibility, as http headers are case insensitive.
This change raises logging severity from `INFO` to `WARN` when handling UNL manifest signed with an unexpected / invalid key. It also changes the internal error code for an invalid format of UNL manifest to `invalid` (from `untrusted`).
This is a follow up to problems experienced by an UNL node due to old manifest key configured in `validators.txt`, which would be easier to diagnose with improved logging.
It also replaces a log line with `UNREACHABLE` for an impossible situation when we match UNL manifest key against a configured key which has an invalid type (we cannot configure such a key because of checks when loading configured keys).
This adds a comment to avoid using `std::counting_semaphore` until the minimum compiler versions of GCC and Clang have been updated to no longer contain the bug that is present in older compilers.
This change reverts #5617, because it will require extensive testing that will take up more time than we have before the next scheduled release.
Reverting this change does not mean we are abandoning it. We aim to pick it back up once there's a sufficient time window to allow for testing on multiple distros running a mixture of OpenSSL 1.x and 3.x.
This change is to improve code coverage (and to simplify #5720 and #5725); there is otherwise no change in functionality. The change adds basic tests for `STInteger` and `STParsedJSON`, so it becomes easier to test smaller changes to the types, as well as removes `STParsedJSONArray`, since it is not used anywhere (including in Clio).
- Added a new Invariant: `ValidPseudoAccounts` which checks that all pseudo-accounts behave consistently through creation and updates, and that no "real" accounts look like pseudo-accounts (which means they don't have a 0 sequence).
- `to_short_string(base_uint)`. Like `to_string`, but only returns the first 8 characters. (Similar to how a git commit ID can be abbreviated.) Used as a wrapped sink to prefix most transaction-related messages. More can be added later.
- `XRPL_ASSERT_PARTS`. Convenience wrapper for `XRPL_ASSERT`, which takes the `function` and `description` as separate parameters.
- `SField::sMD_PseudoAccount`. Metadata option for `SField` definitions to indicate that the field, if set in an `AccountRoot` indicates that account is a pseudo-account. Removes the need for hard-coded field lists all over the place. Added the flag to `AMMID` and `VaultID`.
- Added functionality to `SField` ctor to detect both code and name collisions using asserts. And require all SFields to have a name
- Convenience type aliases `STLedgerEntry::const_pointer` and `STLedgerEntry::const_ref`. (`SLE` is an alias to `STLedgerEntry`.)
- Generalized `feeunit.h` (`TaggedFee`) into `unit.h` (`ValueUnit`) and added new "BIPS"-related tags for future use. Also refactored the type restrictions to use Concepts.
- Restructured `transactions.macro` to do two big things
1. Include the `#include` directives for transactor header files directly in the macro file. Removes the need to update `applySteps.cpp` and the resulting conflicts.
2. Added a `privileges` parameter to the `TRANSACTION` macro, which specifies some of the operations a transaction is allowed to do. These `privileges` are enforced by invariant checks. Again, removed the need to update scattered lists of transaction types in various checks.
- Unit tests:
1. Moved more helper functions into `TestHelpers.h` and `.cpp`.
2. Cleaned up the namespaces to prevent / mitigate random collisions and ambiguous symbols, particularly in unity builds.
3. Generalized `Env::balance` to add support for `MPTIssue` and `Asset`.
4. Added a set of helper classes to simplify `Env` transaction parameter classes: `JTxField`, `JTxFieldWrapper`, and a bunch of classes derived or aliased from it. For an example of how awesome it is, check the changes `src/test/jtx/escrow.h` for how much simpler the definitions are for `finish_time`, `cancel_time`, `condition`, and `fulfillment`.
5. Generalized several of the amount-related helper classes to understand `Asset`s.
6. `env.balance` for an MPT issuer will return a negative number (or 0) for consistency with IOUs.
This change re-enables building and testing all configurations, but only for the daily scheduled run. Previously all configurations were run for each merge into the develop branch, but that overwhelmed both the GitHub runners and the Conan remote, and thus they were limited to just a subset of configurations. Now that the number of jobs is limited via `max-parallel: 10`, we should be able to safely enable building all configurations again. However, building them all once a day instead of for each PR merge should be sufficient.
- Ensures the commits don't get orphaned, even though the relevant code
changes are already included.
* tag '2.5.1':
Set version to 2.5.1
Fix: Don't flag consensus as stalled prematurely (#5658)
GitHub runners have a limit on how many concurrent jobs they can actually process (even though they will try to run them all at the same time), and similarly the Conan remote cannot handle hundreds of concurrent requests. Previously, the Conan dependency uploading was already limited to max 10 jobs running in parallel, and this change makes the same change to the build+test workflow.
This change adds a fix amendment (`fixIncludeKeyletFields`) that adds:
* `sfSequence` to `Escrow` and `PayChannel`
* `sfOwner` to `SignerList`
* `sfOracleDocumentID` to `Oracle`
This ensures that all ledger entries hold all the information needed to determine their keylet.
The XRPL establishes connections in three stages: first a TCP connection, then a TLS/SSL handshake to secure the connection, and finally an upgrade to the bespoke XRP Ledger peer-to-peer protocol. During connection termination, xrpld directly closes the TCP connection, bypassing the TLS/SSL shutdown handshake. This makes peer disconnection diagnostics more difficult - abrupt TCP termination appears as if the peer crashed rather than disconnected gracefully.
This change refactors the connection lifecycle with the following changes:
- Enhanced outgoing connection logic with granular timeouts for each connection stage (TCP, TLS, XRPL handshake) to improve diagnostic capabilities
- Updated both PeerImp and ConnectAttempt to use proper asynchronous TLS shutdown procedures for graceful connection termination
* extends the functionality of the MPTokenIssuanceSet transaction, allowing the issuer to update fields or flags that were explicitly marked as mutable during creation.
Clio should only be notified when releases are about to be made, instead of for all PR, so this change only notifies Clio when a PR targets the release or master branch.
This change wraps all GitHub conditionals in `${{ .. }}`, both for consistency and to reduce unexpected failures, because it was previously noticed that not all conditionals work without those curly braces.
- Amendment: fixDelegateV1_1
- In DelegateSet, disallow invalid PermissionValues like 0, and transaction values when the transaction's amendment is not enabled. Acts as if the transaction doesn't exist, which is the same thing older versions without the amendment will do.
- Payment burn/mint should disallow DEX currency exchange.
- Support MPT for Payment burn/mint.
- Don't run upload-conan-deps in PRs, unless the PR changes the workflow file.
- Change cron schedule for uploading Conan dependencies to run after work hours for most dev.
- This should prevent Artifactory from being overloaded by too many requests at a time.
- Uses "max-parallel" to limit the build job to 10 simultaneous instances.
- Only run the minimal matrix on PRs.
For the purposes of being able to merge a PR, Github Actions jobs count as passed if they ran and passed, or were skipped.
With this change, if any of the jobs that "passed" depends on fail or are cancelled, then "passed" will fail. If they all succeed or are skipped, then "passed" is skipped, which does not prevent a merge.
This saves spinning up a runner in the usual case where things work, and will simplify our branch protection rules, so that only "passed" will need to be checked.
* Add and Scale to VaultCreate
* Add round-trip calculation to VaultDeposit VaultWithdraw and VaultClawback
* Implement Number::truncate() for VaultClawback
* Add rounding to DepositWithdraw
* Disallow zero shares withdraw or deposit with tecPRECISION_LOSS
* Return tecPATH_DRY on overflow when converting shares/assets
* Remove empty shares MPToken in clawback or withdraw (except for vault owner)
* Implicitly create shares MPToken for vault owner in VaultCreate
* Review feedback: defensive checks in shares/assets calculations

Fix stalled consensus detection to prevent false positives in situations where there are no disputed transactions.
Stalled consensus detection was added to 2.5.0 in response to a network consensus halt that caused a round to run for over an hour. However, it has a flaw that makes it very easy to have false positives. Those false positives are usually mitigated by other checks that prevent them from having an effect, but there have been several instances of validators "running ahead" because there are circumstances where the other checks are "successful", allowing the stall state to be checked.
* chore: Use conan lockfile
* Add windows-specific dependencies as well
* Add more info about lockfiles
* Update lockfile to latest version
* Update BUILD.md with conan install note
This is a major refactor of LedgerEntry.cpp. It adds a number of helper functions to make the code easier to maintain.
It also splits up the ledger and ledger_entry tests into different files, and cleans up the ledger_entry tests to make them easier to write and maintain.
This refactor also caught a few bugs in some of the other RPC processing, so those are fixed along the way.
This is a follow-up to PR #5664 that further improves the specificity of logging for refused peer connections. The previous changes did not account for several key scenarios, leading to potentially misleading log messages.
It addresses the following
- Inbound Disabled: Connections are now explicitly logged as rejected when the server is not configured to accept inbound peers. Previously, this was logged as the server being "full," which was technically correct but lacked diagnostic clarity.
- Duplicate Connections: The logging now distinguishes between two types of duplicate connection refusals:
- When a peer with the same node public key is already connected (duplicate connection).
- When a connection is rejected because the limit for connections from a single IP address has been reached.
These changes provide more accurate and actionable diagnostic information when analyzing peer connection behavior.
Test jobs will run if
* Either the PR is non-draft or has the "DraftRunCI" label set *AND*
* One of the following:
* Certain files were changed *OR*
* The PR is non-draft and has the "Ready to merge" flag *OR*
* The workflow is being run from the merge queue.
Additionally, a meta "passed" job was added that is dependent on all the other test jobs, so the required jobs list under branch protection rules only needs to specify "passed" to ensure that *either* all the test jobs pass *or* all the test jobs are skipped because they don't need to be run.
This allows PRs that don't affect the build or binary to be merged without overriding.
This updates Boost to 1.88, which is needed because Clio wants to move to 1.88 as that fixes several ASAN false positives around coroutine usage. In order for Clio to move to newer boost, libXRPL needs to move too. Hence the changes in this PR. A lot has changed between 1.83 and 1.88 so there are lots of changes in the diff, especially in regards to Boost.Asio and coroutines in particular.
This change removes `labeled` and `unlabeled` as pipeline trigger actions, and instead adds `reopened` and `ready_for_review`. The logic whether to run the pipeline jobs is then simplified, although to get a draft PR with the `DraftCIRun` label to run it can be necessary to close and reopen a PR.
The change updates how clang-format is called in CI and locally, and adds prettier to the pre-commit hook. Proto files are now also formatted, while external files are excluded.
This change will skip running the notify-clio job when a PR is created from a fork, and reorders the strategy matrix configuration fields so GitHub will more clearly show which configuration is running.
This change reverts the formatting applied to external files and adds formatting of proto files.
As clang-format will complain if a proto file is modified or moved, since the .clang-format file does not explicitly contain a section for proto files, the change has been included in this PR as well.
This change updates OpenSSL from 1.1.1w to 3.5.2. The code works as-is, but many functions have been marked as deprecated and thus will need to be rewritten. For now we explicitly add the `-DOPENSSL_SUPPRESS_DEPRECATED` to give us time to do so, while providing us with the benefits of the updated version.
This change modifies the `build_only` check used to determine whether to run tests. For easier debugging in the future it also prints out the contents of the strategy matrix.
Reduce log noise by changing two log statements from error/warn level to debug level. These logs occur during normal operation when AMM offers are not available or when IOU authorization checks fail, which are expected scenarios that don't require an elevated log level.
Currently, all peer connection rejections are logged with the reason "slots full". This is inaccurate, as the PeerFinder can also reject connections if they are a duplicate. This change updates the logging logic to correctly report the specific reason (full or duplicate) for a rejected peer connection, providing more accurate diagnostic information.
This change fixes the suite names all around the test files, to make them match to the folder name in which this test files are located. Also, the RCL test files are relocated to the consensus folder, because they are testing consensus functionality.
This change replaces the configuration variable with the hardcoded `https://conan.ripplex.io`, making it possible for PRs from forks to use our Conan remote containing workarounds.
We're currently calling `XXH3_createState` and `XXH3_freeState` when hashing an object. However, it may be slow because they call `malloc` and `free`, which may affect the performance. This change avoids the use of the streaming API as much as possible by using an internal buffer.

This change updates some incorrect Conan commands for Conan 2. As some flags do not exist in Conan 2, such as --settings build_type=[configuration], the commands have been adjusted accordingly. This change further uses the org-level variables and secrets rather than the repo-level ones.
This change introduces two key optimizations:
* Mutex scope reduction: Limits the lock to individual partitions within `TaggedCache`, reducing contention.
* Decoupling: Removes the tight coupling between `LedgerHistory` and `TaggedCache`, improving modularity and testability.
Lock contention analysis based on eBPF showed significant improvements as a result of this change.
This change uploads built Conan dependencies to the Conan remote upon merge into the develop branch.
At the moment, whenever Conan dependencies change, we need to remember to manually push them to our Conan remote, so they are cached for future reuse. If we forget to do so, these changed dependencies need to be rebuilt over and over again, which can take a long time.
This change:
* Removes the patched Conan recipes from the `external/` directory.
* Adds instructions for contributors how to obtain our patched recipes.
* Updates the Conan remote name and remote URL (the underlying package repository isn't changed).
* If the remote already exists, updates the URL instead of removing and re-adding.
* This is not done for the libXRPL job as it still uses Conan 1. This job will be switched to Conan 2 soon.
* Removes duplicate Conan remote CI pipeline steps.
* Overwrites the existing global.conf on MacOS and Windows machines, as those do not run CI pipelines in isolation but all share the same Conan installation; appending the same config over and over bloats the file.
This change updates BUILD.md for Conan 2, add fixes/workarounds for Apple Clang 17, Clang 20 and CMake 4. This also removes (from BUILD.md only) workarounds for compiler versions which we no longer support e.g. Clang 15 and adds compilation flag -Wno-deprecated-declarations to enable building with Clang 20 on Linux.
This change fixes an issue where the order of `PriceDataSeries` was out of sync between when `PriceOracle` was created and when it was updated. Although they are registered in the canonical order when updated, they are created using the order specified in the transaction; this change ensures that they are also registered in the canonical order when created.
This change decouples `ledger` from `xrpld/app`, and therefore fully clears the path to the modularisation of the ledger component. Before this change, `View.cpp` relied on `MPTokenAuthorize::authorize; this change moves `MPTokenAuthorize::authorize` to `View.cpp` to invert the dependency, making ledger a standalone module.
The Payment transaction metadata is missing the `DeliveredAmount` field that displays the actual amount delivered to the destination excluding transfer fees. This amendment fixes this problem.
#5224 added (among other things) a `VaultWithdraw` transaction that allows setting the recipient of the withdrawn funds in the `Destination` transaction field. This technically turns this transaction into a payment, and in some respect the implementation does follow payment rules, e.g. enforcement of `lsfRequireDestTag` or `lsfDepositAuth`, or that MPT transfer has destination `MPToken`. However for IOUs, it missed verification that the destination account has a trust line to the asset issuer. Since the default behavior of `accountSendIOU` is to create this trust line (if missing), this is what `VaultWithdraw` currently does. This is incorrect, since the `Destination` might not be interested in holding the asset in question; this basically enables spammy transfers. This change, therefore, removes automatic creation of a trust line to the `Destination` account in `VaultWithdraw`.
This change updates RocksDB to its latest version. RocksDB is backward-compatible, so even though this is a major version bump, databases created with previous versions will continue to function.
The external RocksDB folder is removed, as the latest version available via Conan Center no longer needs custom patches.
Before `XRPLF/ci` images, we did not have a `dependencies:` job for clang-16, so `instrumentation:` had to build its own dependencies. Now we have clang-16 Conan dependencies built in a separate job that can be used.
This change includes `network_id` data in the validations and ledger subscription stream responses, as well as unit tests to validate the response fields. Fixes#4783
This change adds support for `DomainID` to existing transactions `MPTokenIssuanceCreate` and `MPTokenIssuanceSet`.
In #5224 `DomainID` was added as an access control mechanism for `SingleAssetVault`. The actual implementation of this feature lies in `MPToken` and `MPTokenIssuance`, hence it makes sense to enable the use of `DomainID` also in `MPTokenIssuanceCreate` and `MPTokenIssuanceSet`, following same rules as in Vault:
* `MPTokenIssuanceCreate` and `MPTokenIssuanceSet` can only set `DomainID` if flag `MPTRequireAuth` is set.
* `MPTokenIssuanceCreate` requires that `DomainID` be a non-zero, uint256 number.
* `MPTokenIssuanceSet` allows `DomainID` to be zero (or empty) in which case it will remove `DomainID` from the `MPTokenIssuance` object.
The change is amendment-gated by `SingleAssetVault`. This is a non-breaking change because `SingleAssetVault` amendment is `Supported::no`, i.e. at this moment considered a work in progress, which cannot be enabled on the network.
For jobs running in containers, $GITHUB_WORKSPACE and ${{ github.workspace }} might not be the same directory. The actions/checkout step is supposed to checkout into `$GITHUB_WORKSPACE` and then add it to safe.directory (see instructions at https://github.com/actions/checkout), but that's apparently not happening for some container images. We can't be sure what is actually happening, so we preemptively add both directories to `safe.directory`. See also the GitHub issue opened in 2022 that still has not been resolved https://github.com/actions/runner/issues/2058.
The current implementation of rngfill is prone to false warnings from GCC about array bounds violations. Looking at the code, the implementation naively manipulates both the bytes count and the buffer pointer directly to ensure the trailing memcpy doesn't overrun the buffer. As expressed, there is a data dependency on both fields between loop iterations.
Now, ideally, an optimizing compiler would realize that these dependencies were unnecessary and end up restructuring its intermediate representation into a functionally equivalent form with them absent. However, the point at which this occurs may be disjoint from when warning analyses are performed, potentially rendering them more difficult to
determine precisely.
In addition, it may also consume a portion of the budget the optimizer has allocated to attempting to improve a translation unit's performance. Given this is a function template which requires context-sensitive instantiation, this code would be more prone than most to being inlined, with a decrease in optimization budget corresponding to the effort the optimizer has already expended, having already optimized one or more calling functions. Thus, the scope for impacting the the ultimate quality of the code generated is elevated.
For this change, we rearrange things so that the location and contents of each memcpy can be computed independently, relying on a simple loop iteration counter as the only changing input between iterations.
Remove `include(default)` from `conan/profiles/libxrpl`. This means that we will now rely on compiler workarounds stored elsewhere e.g. in global.conf.
This change reverts the usage of boost::shared_mutex back to std::shared_mutex. The change was originally introduced as a workaround for a bug in glibc 2.28 and older versions, which could cause threads using std::shared_mutex to stall. This issue primarily affected Ubuntu 18.04 and earlier distributions, which we no longer support.
This change fixes the MacOS pipeline issue by limiting GitHub to choose the existing runners, ensuring the new experimental runners are excluded until they are ready.
This issue was reported on the Javascript client library: XRPLF/xrpl.js#2611
The type filter (Note: as of the latest version of rippled, type parameter is deprecated) does not work as expected. This PR removes the type filter from the ledger command.
This PR updates several dependencies to their latest versions. Not all dependencies have been updated, as some need to be patched and some require additional code changes due to backward incompatibilities introduced by the version bump.
Due to rounding, the LPTokenBalance of the last LP might not match the LP's trustline balance. This was fixed for `AMMWithdraw` in `fixAMMv1_1` by adjusting the LPTokenBalance to be the same as the trustline balance. Since `AMMClawback` is also performing a withdrawal, we need to adjust LPTokenBalance as well in `AMMClawback.`
This change includes:
1. Refactored `verifyAndAdjustLPTokenBalance` function in `AMMUtils`, which both`AMMWithdraw` and `AMMClawback` call to adjust LPTokenBalance.
2. Added the unit test `testLastHolderLPTokenBalance` to test the scenario.
3. Modify the existing unit tests for `fixAMMClawbackRounding`.
Currently there is no easy way to track MPT related transactions for the issuer. This change allows MPT transactions to show up on issuer's AccountTx RPC (to align with how IOUs work).
* Update the `account_info` API so that the `allowTrustLineLocking` flag is included in the response.
* The proposed `TokenEscrow` amendment added an `allowTrustLineLocking` flag in the `AccountRoot` object.
* In the API response, under `account_flags`, there is now an `allowTrustLineLocking` field with a boolean (`true` or `false`) value.
* For reference, the XLS-85 Token-Enabled Escrows implementation can be found in https://github.com/XRPLF/rippled/pull/5185
The current version was copied from `antithesis-sdk-cpp` but there is no logical reason to require this specific version of CMake. This change downgrades the version to make the project build with older CMake versions.
Having `boost::boost` in `self.requires` makes clio link with all boost libraries. There are additionally several Boost stacktrace backends that are both linked with, which violate ODR.
This change fixes the problem.
This PR refactors `CredentialHelpers` and removes some unnecessary dependencies as a step of modularization.
The ledger component is almost independent except that it references `MPTokenAuthorize` and `CredentialHelpers.h`, and the latter further references `Transactor.h`. This PR partially clears the path to modularizing the ledger component and decouples `CredentialHelpers` from xrpld.
This PR fixes a crash in tests when the test `Env is run at trace/debug log level.
This issue only affects tests, and only if logging at trace/debug level, so really only relevant during rippled development, and does not affect production servers.
The tests that ensure `tfInnerBatchTxn` won't block delegated transactions silently fail in `Delegate_test.cpp`. This change removes these cases from that file and adds them to `Batch_test.cpp` instead where they do not silently fail, because there the batch delegate results are explicitly checked. Moving them to that file further avoids refactoring many helper functions.
This change allows users to submit simulate requests from a multi-sign account without needing to specify the accounts that are doing the multi-signing, and fixes an error with simulate that allowed double-"signed" (both single-sign and multi-sign public keys are provided) transactions.
Multi-line log messages are hard to work with. Writing these handful of related messages as one message should make the log a tiny bit easier to manage.
The CMake statements that make it seem as if the number of cores used to build external project dependencies is halved don't actually do anything. This change removes these statements.
* Adds `tecNO_DELEGATE_PERMISSION` for unauthorized transactions sent by a delegated account.
* Returns `tecNO_TARGET` instead of `terNO_ACCOUNT` for the `DelegateSet` transaction if the delegated account does not exist.
* Fixes `tfFullyCanonicalSig` and `tfInnerBatchTxn` blocking transactions issue by adding `tfUniversal` in the permission related masks in `txFlags.h`
The change increases the default network I/O worker thread pool size from 2 to 6. This will improve stability, as worker thread saturation correlates to desyncs, particularly on high-traffic peers, such as hubs.
To be able to consume `rippled` in Conan 2, the recipe should specify transitive_headers for external libraries that are present in the exported header files. This change remains compatibility with Conan 1, where this flag was not present.
- Specification: https://github.com/XRPLF/XRPL-Standards/pull/272
- Amendment: `TokenEscrow`
- Enables escrowing of IOU and MPT tokens in addition to native XRP.
- Allows accounts to lock issued tokens (IOU/MPT) in escrow objects, with support for freeze, authorization, and transfer rates.
- Adds new ledger fields (`sfLockedAmount`, `sfIssuerNode`, etc.) to track locked balances for IOU and MPT escrows.
- Updates EscrowCreate, EscrowFinish, and EscrowCancel transaction logic to support IOU and MPT assets, including proper handling of trustlines and MPT authorization, transfer rates, and locked balances.
- Enforces invariant checks for escrowed IOU/MPT amounts.
- Extends GatewayBalances RPC to report locked (escrowed) balances.
The changes are focused on fixing NFT transactions bypassing the trustline authorization requirement and potential invariant violation when interacting with deep frozen trustlines.
* Add AMM bid/create/deposit/swap/withdraw/vote invariants:
- Deposit, Withdrawal invariants: `sqrt(asset1Balance * asset2Balance) >= LPTokens`.
- Bid: `sqrt(asset1Balance * asset2Balance) > LPTokens` and the pool balances don't change.
- Create: `sqrt(asset1Balance * assetBalance2) == LPTokens`.
- Swap: `asset1BalanceAfter * asset2BalanceAfter >= asset1BalanceBefore * asset2BalanceBefore`
and `LPTokens` don't change.
- Vote: `LPTokens` and pool balances don't change.
- All AMM and swap transactions: amounts and tokens are greater than zero, except on withdrawal if all tokens
are withdrawn.
* Add AMM deposit and withdraw rounding to ensure AMM invariant:
- On deposit, tokens out are rounded downward and deposit amount is rounded upward.
- On withdrawal, tokens in are rounded upward and withdrawal amount is rounded downward.
* Add Order Book Offer invariant to verify consumed amounts. Consumed amounts are less than the offer.
* Fix Bid validation. `AuthAccount` can't have duplicate accounts or the submitter account.
This commit changes the ledger close in env.meta to be conditional on if it hasn't already been closed (i.e. the current ledger doesn't have any transactions in it). This change will make it a bit easier to use, as it will still work if you close the ledger outside of this usage. Previously, if you accidentally closed the ledger outside of the meta function, it would segfault and it was incredibly difficult to debug.
This commit introduces the following changes:
* Renames `vp_enable config` option to `vp_base_squelch_enable` to enable squelching for validators.
* Removes `vp_squelch` config option which was used to configure whether to send squelch messages to peers or not. With this flag removed, if squelching is enabled, squelch messages will be sent. This was an option used for debugging.
* Introduces a temporary `vp_base_squelch_max_trusted_peers` config option to change the max number of peers who are selected as validator message sources. This is a temporary option, which will be removed once a good value is found.
* Adds a traffic counter to count the number of times peers ignored squelch messages and kept sending messages for squelched validators.
* Moves the decision whether squelching is enabled and ready into Slot.h.
- Specification: [XRPLF/XRPL-Standards 56](https://github.com/XRPLF/XRPL-Standards/blob/master/XLS-0056d-batch/README.md)
- Amendment: `Batch`
- Implements execution of multiple transactions within a single batch transaction with four execution modes: `tfAllOrNothing`, `tfOnlyOne`, `tfUntilFailure`, and `tfIndependent`.
- Enables atomic multi-party transactions where multiple accounts can participate in a single batch, with up to 8 inner transactions and 8 batch signers per batch transaction.
- Inner transactions use `tfInnerBatchTxn` flag with zero fees, no signature, and empty signing public key.
- Inner transactions are applied after the outer batch succeeds via the `applyBatchTransactions` function in apply.cpp.
- Network layer prevents relay of transactions with `tfInnerBatchTxn` flag - each peer applies inner transactions locally from the batch.
- Batch transactions are excluded from AccountDelegate permissions but inner transactions retain full delegation support.
- Metadata includes `ParentBatchID` linking inner transactions to their containing batch for traceability and auditing.
- Extended STTx with batch-specific signature verification methods and added protocol structures (`sfRawTransactions`, `sfBatchSigners`).
Before #5224, the pseudoaccount ID was calculated using prefix expressed in `std::uint16_t`. The refactoring to move the pseudoaccount ID calculation to View.cpp had accidentally changed the prefix type to `int` (derived from `auto i = 0`) which in turn changed the length of the input to `sha512Half` from 2 bytes to 4, altering the result.
This resulted in a different ID of the pseudoaccount calculated from the function after the refactoring, breaking the ledger. This impacts AMMCreate, even when the `SingleAssetVault` amendment is not active. This change restores the prefix type to `std::uint16_t`.
- Specification: XRPLF/XRPL-Standards#239
- Amendment: `SingleAssetVault`
- Implements a vault feature used to store a fungible asset (XRP, IOU, or MPT, but not NFT) and to receive shares in the vault (an MPT) in exchange.
- A vault can be private or public.
- A private vault can use permissioned domains, subject to the `PermissionedDomains` amendment.
- Shares can be exchanged back into asset with `VaultWithdraw`.
- Permissions on the asset in the vault are transitively applied on shares in the vault.
- Issuer of the asset in the vault can clawback with `VaultClawback`.
- Extended `MPTokenIssuance` with `DomainID`, used by the permissioned domain on the vault shares.

Using std::barrier performs extremely poorly (~1 hour vs ~1 minute to run the test suite) in certain macOS environments.
To unblock our macOS CI pipeline, std::barrier has been replaced with a custom mutex-based barrier (Barrier) that significantly improves performance without compromising correctness.
Running unit tests in parallel and multiple threads can write into one file can corrupt output files, and then gcovr won't be able to parse the corrupted file. This change adds -fprofile-update=atomic as instructed by https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68080.
This change implements the account permission delegation described in XLS-75d, see https://github.com/XRPLF/XRPL-Standards/pull/257.
* Introduces transaction-level and granular permissions that can be delegated to other accounts.
* Adds `DelegateSet` transaction to grant specified permissions to another account.
* Adds `ltDelegate` ledger object to maintain the permission list for delegating/delegated account pair.
* Adds an optional `Delegate` field in common fields, allowing a delegated account to send transactions on behalf of the delegating account within the granted permission scope. The `Account` field remains the delegating account; the `Delegate` field specifies the delegated account. The transaction is signed by the delegated account.
This change updates the squelching logic to accept squelch messages for untrusted validators. As a result, servers will also squelch untrusted validator messages reducing duplicate traffic they generate.
In particular:
* Updates squelch message handling logic to squelch messages for all validators, not only trusted ones.
* Updates the logic to send squelch messages to peers that don't squelch themselves
* Increases the threshold for the number of messages that a peer has to deliver to consider it as a candidate for validator messages.
Combines four related changes:
1. "Decrease `shouldRelay` limit to 30s." Pretty self-explanatory. Currently, the limit is 5 minutes, by which point the `HashRouter` entry could have expired, making this transaction look brand new (and thus causing it to be relayed back to peers which have sent it to us recently).
2. "Give a transaction more chances to be retried." Will put a transaction into `LedgerMaster`'s held transactions if the transaction gets a `ter`, `tel`, or `tef` result. Old behavior was just `ter`.
* Additionally, to prevent a transaction from being repeatedly held indefinitely, it must meet some extra conditions. (Documented in a comment in the code.)
3. "Pop all transactions with sequential sequences, or tickets." When a transaction is processed successfully, currently, one held transaction for the same account (if any) will be popped out of the held transactions list, and queued up for the next transaction batch. This change pops all transactions for the account, but only if they have sequential sequences (for non-ticket transactions) or use a ticket. This issue was identified from interactions with @mtrippled's #4504, which was merged, but unfortunately reverted later by #4852. When the batches were spaced out, it could potentially take a very long time for a large number of held transactions for an account to get processed through. However, whether batched or not, this change will help get held transactions cleared out, particularly if a missing earlier transaction is what held them up.
4. "Process held transactions through existing NetworkOPs batching." In the current processing, at the end of each consensus round, all held transactions are directly applied to the open ledger, then the held list is reset. This bypasses all of the logic in `NetworkOPs::apply` which, among other things, broadcasts successful transactions to peers. This means that the transaction may not get broadcast to peers for a really long time (5 minutes in the current implementation, or 30 seconds with this first commit). If the node is a bottleneck (either due to network configuration, or because the transaction was submitted locally), the transaction may not be seen by any other nodes or validators before it expires or causes other problems.
This change addresses an issue where `rippled` attempts to connect to an IPv6 address, even when the local network lacks IPv6 support, resulting in a "Network is unreachable" error.
The fix replaces the custom endpoint selection logic with `boost::async_connect`, which sequentially attempts to connect to available endpoints until one succeeds or all fail.
This PR replaces the word `failed` with `failure` in any test names and renames some test files to fix MSVC warnings, so that it is easier to search through the test output to find tests that failed.
This change fixes a number of issues involved with CTID:
* CTID is not present on all RPC tx transactions.
* rpcWRONG_NETWORK is missing in the ErrorCodes.cpp
When using subscribe at admin RPC port to send webhooks for the transaction stream to a backend, on large(r) ledgers the endpoint receives fewer HTTP POSTs with TX information than the amount of transactions in a ledger. This change removes the hardcoded queue length to avoid dropping TX notifications for the admin-only command. In addition, the per-request TTL for outgoing RPC HTTP calls has been reduced from 10 minutes to 30 seconds.
This change introduces a new fix amendment (`fixPayChanV1`) that prevents the creation of new `PaymentChannelCreate` transaction with a `CancelAfter` time less than the current ledger time. It piggy backs off of fix1571.
Once the amendment is activated, creating a new `PaymentChannel` will require that if you specify the `CancelAfter` time/value, that value must be greater than or equal to the current ledger time.
Currently users can create a payment channel where the `CancelAfter` time is before the current ledger time. This results in the payment channel being immediately closed on the next PaymentChannel transaction.
This PR splits out `ledger_entry` tests into its own file (`LedgerEntry_test.cpp`) and alphabetizes the helper functions in `LedgerEntry.cpp`. These commits were split out of #5237 to make that PR a little more manageable, since these basic trivial changes are most of the diff. There is no code change, just moving code around.
Adds metric counters for the following P2P message types:
* Untrusted proposal and validation messages
* Duplicate proposal, validation and transaction messages
It’s possible for this to happen legitimately if a set of peers, including a validator, are connected in a cycle, and the latency and message processing time between those peers is significantly less than the latency between the validator and the last peer. It’s unlikely in the real world, but obviously easy to simulate with Antithesis.
The ci pipelines are constantly hitting Docker Hub's public rate limiting since increasing the number of jobs we're running. This change switches over to images hosted in GitHub's registry.
As part of import optimization, a transitive include had been removed that defined `BOOST_COMP_MSVC` on Windows. In unity builds, this definition was pulled in, but in non-unity builds it was not - causing a compilation error. An inspection of the Boost code revealed that we can just gate the statements by `_MS_VER` instead. A `#pragma message` is added to verify that the statement is only printed on Windows builds.
The main goal of this optimisation is memory reduction in SHAMapTreeNodes by introducing intrusive pointers instead of standard std::shared_ptr and std::weak_ptr.
In preparation for a potential reference fee change we would like to verify that fee change works as expected. The first step is to fix all unit tests to be able to work with different reference fee values.
- Detects if the consensus process is "stalled". If it is, then we can declare a
consensus and end successfully even if we do not have 80% agreement on
our proposal.
- "Stalled" is defined as:
- We have a close time consensus
- Each disputed transaction is individually stalled:
- It has been in the final "stuck" 95% requirement for at least 2
(avMIN_ROUNDS) "inner rounds" of phaseEstablish,
- and either all of the other trusted proposers or this validator, if proposing,
have had the same vote(s) for at least 4 (avSTALLED_ROUNDS) "inner
rounds", and at least 80% of the validators (including this one, if
appropriate) agree about the vote (whether yes or no).
- If we have been in the establish phase for more than 10x the previous
consensus establish phase's time, then consensus is considered "expired",
and we will leave the round, which sends a partial validation (indicating
that the node is moving on without validating). Two restrictions avoid
prematurely exiting, or having an extended exit in extreme situations.
- The 10x time is clamped to be within a range of 15s
(ledgerMAX_CONSENSUS) to 120s (ledgerABANDON_CONSENSUS).
- If consensus has not had an opportunity to walk through all avalanche
states (defined as not going through 8 "inner rounds" of phaseEstablish),
then ConsensusState::Expired is treated as ConsensusState::No.
- When enough nodes leave the round, any remaining nodes will see they've
fallen behind, and move on, too, generally before hitting the timeout. Any
validations or partial validations sent during this time will help the
consensus process bring the nodes back together.
This change removes the existing undefined behavior from `LogicError`, so we can be certain that there will be always a stacktrace.
De-referencing a null pointer is an old trick to generate `SIGSEGV`, which would typically also create a stacktrace. However it is also an undefined behaviour and compilers can do something else. A more robust way to create a stacktrace while crashing the program is to use `std::abort`, which we have also used in this location for a long time. If we combine the two, we might not get the expected behaviour - namely, the nullpointer deref followed by `std::abort`, as handled in certain compiler versions may not immediately cause a crash. We have observed stacktrace being wiped instead, and thread put in indeterminate state, then stacktrace created without any useful information.
The Trustline RPC `no_ripple` flag gets set depending on `lsfDefaultRipple` flag, which is not a flag of a trustline but of the account root. The `lsfDefaultRipple` flag does not provide any insight if this particular trust line has `lsfLowNoRipple` or `lsfHighNoRipple` flag set, so it should not be used here at all. This change simplifies the logic.
The `end_marker` is used to limit the range of ledger entries to fetch. If `end_marker` is less than `marker`, a crash can occur. This change adds an additional check.
Changes the error to `malformedAddress` for `permissioned_domain` in the `ledger_entry` rpc, when the account is not a string. This change makes it more clear to a user what is wrong with their request.
What the LoadManager class does is stall detection, which is not the same as deadlock detection. In the condition of severe CPU starvation, LoadManager will currently intentionally crash rippled reporting `LogicError: Deadlock detected`. This error message is misleading as the condition being detected is not a deadlock. This change fixes and refactors the code in response.
Requiring manual updates of numFeatures is an annoying manual process that is easily forgotten, and leads to frequent merge conflicts. This change takes advantage of the `XRPL_FEATURE` and `XRPL_FIX` macros, and adds a new `XRPL_RETIRE` macro to automatically set `numFeatures`.
The codebase is filled with includes that are unused, and which thus can be removed. At the same time, the files often do not include all headers that contain the definitions used in those files. This change uses clang-format and clang-tidy to clean up the includes, with minor manual intervention to ensure the code compiles on all platforms.
- PR #5228 added assert=TRUE and werr=TRUE CMake flags to the
build/action.yml script which is used by all CI jobs to build rippled,
ensuring those flags were always set. The assumption was that only the
CI jobs used that script, so any extra time cost was offset by the
benefit of the extra checks. That assumption was incorrect. That
script is used by other downstream projects. Therefore, those flags
have been moved into the individual CI jobs' "cmake-args" parameter
passed to build/action.yml. This will have the same effect for CI jobs
without any side effects.
Combine multiple related debug log data points into a single
message. Allows quick correlation of events that
previously were either not logged or, if logged, strewn
across multiple lines, making correlation difficult.
The Heartbeat Timer and consensus ledger accept processing
each have this capability.
Also guarantees that log entries will be written if the
node is a validator, regardless of log severity level.
Otherwise, the level of these messages is at INFO severity.
* Add logging for amendment voting decision process
* When counting "received validations" to determine quorum, count the number of validators actually voting, not the total number of possible votes.
The current comment in the example cfg file incorrectly mentions both "may" and "must". This change fixes this comment to clarify that the default port of hosts is 2459 and that specifying it is therefore optional. It further sets the default port to 2459 instead of the legacy 51235.
- Drop duplicate outgoing TMGetLedger messages per peer
- Allow a retry after 30s in case of peer or network congestion.
- Addresses RIPD-1870
- (Changes levelization. That is not desirable, and will need to be fixed.)
- Drop duplicate incoming TMGetLedger messages per peer
- Allow a retry after 15s in case of peer or network congestion.
- The requestCookie is ignored when computing the hash, thus increasing
the chances of detecting duplicate messages.
- With duplicate messages, keep track of the different requestCookies
(or lack of cookie). When work is finally done for a given request,
send the response to all the peers that are waiting on the request,
sending one message per peer, including all the cookies and
a "directResponse" flag indicating the data is intended for the
sender, too.
- Addresses RIPD-1871
- Drop duplicate incoming TMLedgerData messages
- Addresses RIPD-1869
- Improve logging related to ledger acquisition
- Class "CanProcess" to keep track of processing of distinct items

This change enhances the filtering in the ledger, ledger_data, and account_objects methods by also supporting filtering by the canonical name of the LedgerEntryType using case-insensitive matching.
Rewrites the code so that the lock is not held during the callback. Instead it locks twice, once before, and once after. This is safe due to the structure of the code, but is checked after the second lock. This allows mutex_ to be changed back to a regular mutex.
In PeerImpl.cpp, if the function is a message handler (onMessage) or called directly from a message handler, then it should use fee_, since when the handler returns (OnMessageEnd) then the charge function is called. If the function is not a message handler, such as a job queue item, it should remain charge.
- Rename the job in missing-commits.yml from "check" to "up_to_date",
because other jobs named "check" prevent merges, but this one should
not prevent merges. How else are branches going to get caught up?
- Move the job in instrumentation.yml to nix.yml, but keep it entirely
independent.
If the permissioned domains amendment XLS-80 is enabled before credentials XLS-70, then the permissioned domain users will not be able to match any credentials. The changes here prevent the creation of any permissioned domain objects if credentials are not enabled.
Make `simulate` RPC easier to use:
* Prevent the use of `seed`, `secret`, `seed_hex`, and `passphrase` fields (to avoid confusing with the signing methods).
* Add autofilling of the `NetworkID` field.
- Also get the branch name.
- Use rev-parse instead of describe to get a clean hash.
- Return the git hash and branch name in server_info for admin
connections.
- Include git hash and branch name on separate lines in --version.
- spec: XRPLF/XRPL-Standards#220
- amendment: "DeepFreeze"
- implemented deep freeze spec to allow token issuers to prevent currency holders from being able to acquire more of these tokens.
- in combination with normal freeze, deep freeze effectively prevents any balance trust line balance change of a currency holder (except direct issuer <-> holder payments).
- added 2 new invariant checks to verify that deep freeze cannot be enacted without normal freeze and transfer is not frozen.
- made some fixes to existing freeze handling.

- Fix an erroneous high fee penalty that peers could incur for sending
older transactions.
- Update to the fees charged for imposing a load on the server.
- Prevent the relaying of internal pseudo-transactions.
- Before: Pseudo-transactions received from a peer will fail the signature
check, even if they were requested (using TMGetObjectByHash), because
they have no signature. This causes the peer to be charge for an
invalid signature.
- After: Pseudo-transactions, are put into the global cache
(TransactionMaster) only. If the transaction is not part of
a TMTransactions batch, the peer is charged an unwanted data fee.
These fees will not be a problem in the normal course of operations,
but should dissuade peers from behaving badly by sending a bunch of
junk.
- Improve logging: include the reason for fees charged to a peer.

* Has more steps, but allows merges to develop to continue when a
beta / RC is pending, increasing developer velocity.
* Add a CI job to check that no reverse merges have been missed.
* Add some useful scripts in bin/git:
* Set up upstreams as expected for safer pushes
* Squash a bunch of branches
* Set the version number
* Resolves an issue introduced in #5111, which inadvertently removed the
-Wno-maybe-uninitialized compiler option from some xrpl.libxrpl
modules. This resulted in new "may be used uninitialized" build
warnings, first noticed in the "protocol" module. When compiling with
derr=TRUE, those warnings became errors, which made the build fail.
* Github CI actions will build with the assert and werr options turned
on. This will cause CI jobs to fail if a developer introduces a new
compiler warning, or causes an assert to fail in release builds.
* Includes the OS and compiler version in the linux dependencies jobs in
the "check environment" step.
* Translates the `unity` build option into `CMAKE_UNITY_BUILD` setting.
The LEDGER_ENTRY macro now takes an additional parameter, which makes it easier to avoid missing including the new field in jss.h and to the list of account_objects/ledger_data filters.
Replace Issue in STIssue with Asset. STIssue with MPTIssue is only used in MPT tests.
Will be used in Vault and in transactions with STIssue fields once MPT is integrated into DEX.
* Rename ASSERT to XRPL_ASSERT
* Upgrade to Anthithesis SDK 0.4.4, and use new 0.4.4 features
* automatic cast to bool, like assert
* Add instrumentation workflow to verify build with instrumentation enabled
Adds two CMake functions:
* add_module(library subdirectory): Declares an OBJECT "library" (a CMake abstraction for a collection of object files) with sources from the given subdirectory of the given library, representing a module. Isolates the module's headers by creating a subdirectory in the build directory, e.g. .build/tmp123, that contains just a symlink, e.g. .build/tmp123/basics, to the module's header directory, e.g. include/xrpl/basics, in the source directory, and putting .build/tmp123 (but not include/xrpl) on the include path of the module sources. This prevents the module sources from including headers not explicitly linked to the module in CMake with target_link_libraries.
* target_link_modules(library scope modules...): Links the library target to each of the module targets, and removes their sources from its source list (so they are not compiled and linked twice).
Uses these functions to separate and explicitly link modules in libxrpl:
Level 01: beast
Level 02: basics
Level 03: json, crypto
Level 04: protocol
Level 05: resource, server
* Copy Antithesis SDK version 0.4.0 to directory external/
* Add build option `voidstar` to enable instrumentation with Antithesis SDK
* Define instrumentation macros ASSERT and UNREACHABLE in terms of regular C assert
* Replace asserts with named ASSERT or UNREACHABLE
* Add UNREACHABLE to LogicError
* Document instrumentation macros in CONTRIBUTING.md
`STNumber` lets objects and transactions contain multiple fields for
quantities of XRP, IOU, or MPT without duplicating information about the
"issue" (represented by `STIssue`). It is a straightforward serialization of
the `Number` type that uniformly represents those quantities.

* 2.2.2 changed functions acquireAsync and NetworkOPsImp::recvValidation to add an item to a collection under lock, unlock, do some work, then lock again to do remove the item. It will deadlock if an exception is thrown while adding the item - before unlocking.
* Replace ScopedUnlock with scope_unlock.
Move the newest information to the top, i.e., use reverse chronological order within each of the two sections ("API Versions" and "XRP Ledger server versions")
The page_size will soon be made configurable with #5135, making this
re-ordering necessary.
When opening SQLite connection, there are specific pragmas set with
commonPragmas.
In particular, PRAGMA journal_mode creates journal file and locks the
page_size; as of this commit, this sets the page size to the default
value of 4096. Coincidentally, the hardcoded page_size was also 4096, so
no issue was noticed.
Update book_changes RPC to reduce latency, add "validated" field, and accept shortcut strings (current, closed, validated) for ledger_index.
`"validated": true` indicates that the transaction has been included in a validated ledger so the result of the transaction is immutable.

When rippled initiates a connection to SQLite3, rippled sends a "PRAGMA"
statement defining the maximum number of pages allowed in the database.
Update the max_page_count so it is consistent with the default for newer
versions of SQLite3. Increasing max_page_count is critical for keeping
full history servers online.

Implements a CI workflow that detects when a new version of libxrpl is
proposed, uploads it to artifactory under the `clio` channel and
notifies Clio's CI to check this newly proposed version.
* Add fixNFTokenPageLinks amendment:
It was discovered that under rare circumstances the links between
NFTokenPages could be removed. If this happens, then the
account_objects and account_nfts RPC commands under-report the
NFTokens owned by an account.
The fixNFTokenPageLinks amendment does the following to address
the problem:
- It fixes the underlying problem so no further broken links
should be created.
- It adds Invariants so, if such damage were introduced in the
future, an invariant would stop it.
- It adds a new FixLedgerState transaction that repairs
directories that were damaged in this fashion.
- It adds unit tests for all of it.
* `account_objects` returns an invalid field error if `type` is not supported.
This includes objects an account can't own, or which are unsupported by `account_objects`
* Includes:
* Amendments
* Directory Node
* Fee Settings
* Ledger Hashes
* Negative UNL
The names of the files should reflect the name of the Dir class.

Fix interactions between NFTokenOffers and trust lines.
Since the NFTokenAcceptOffer does not check the trust line that
the issuer receives as a transfer fee in the NFTokenAcceptOffer,
if the issuer deletes the trust line after NFTokenCreateOffer,
the trust line is created for the issuer by the
NFTokenAcceptOffer. That's fixed.
Resolves#4925.
Fixes issue #4937.
The fixReducedOffersV1 amendment fixed certain forms of offer
modification that could lead to blocked order books. Reduced
offers can block order books if the effective quality of the
reduced offer is worse than the quality of the original offer
(from the perspective of the taker). It turns out that, for
small values, the quality of the reduced offer can be
significantly affected by the rounding mode used during
scaling computations.
Issue #4937 identified an additional code path that modified
offers in a way that could lead to blocked order books. This
commit changes the rounding in that newly located code path so
the quality of the modified offer is never worse than the
quality of the offer as it was originally placed.
It is possible that additional ways of producing blocking
offers will come to light. Therefore there may be a future
need for a V3 amendment.
* Add trap_tx_hash command line option
This new option can be used only if replay is also enabled. It takes a transaction hash from the ledger loaded for replay, and will cause a specific line to be hit in Transactor.cpp, right before the selected transaction is applied.
Price Oracle data-series logic uses `unordered_map` to update the Oracle object.
This results in different servers disagreeing on the order of that hash table.
Consequently, the generated ledgers will have different hashes.
The fix uses `map` instead to guarantee the order of the token pairs
in the data-series.
Due to the rounding, LPTokenBalance of the last
Liquidity Provider (LP), might not match this LP's
trustline balance. This fix sets LPTokenBalance on
last LP withdrawal to this LP's LPToken trustline
balance.
Single path AMM offer has to factor in the transfer in rate
when calculating the upper bound quality and the quality function
because single path AMM's offer quality is not constant.
This fix factors in the transfer fee in
BookStep::adjustQualityWithFees().
* Fix AMM offer rounding and low quality LOB offer blocking AMM:
A single-path AMM offer with account offer on DEX, is always generated
starting with the takerPays first, which is rounded up, and then
the takerGets, which is rounded down. This rounding ensures that the pool's
product invariant is maintained. However, when one of the offer's side
is XRP, this rounding can result in the AMM offer having a lower
quality, potentially causing offer generation to fail if the quality
is lower than the account's offer quality.
To address this issue, the proposed fix adjusts the offer generation process
to start with the XRP side first and always rounds it down. This results
in a smaller offer size, improving the offer's quality. Regardless if the offer
has XRP or not, the rounding is done so that the offer size is minimized.
This change still ensures the product invariant, as the other generated
side is the exact result of the swap-in or swap-out equations.
If a liquidity can be provided by both AMM and LOB offer on offer crossing
then AMM offer is generated so that it matches LOB offer quality. If LOB
offer quality is less than limit quality then generated AMM offer quality
is also less than limit quality and the offer doesn't cross. To address
this issue, if LOB quality is better than limit quality then use LOB
quality to generate AMM offer. Otherwise, don't use the quality to generate
AMM offer. In this case, limitOut() function in StrandFlow limits
the out amount to match strand's quality to limit quality and consume
maximum AMM liquidity.
Rounding in the payment engine is causing an assert to sometimes fire
with "dust" amounts. This is causing issues when running debug builds of
rippled. This issue will be addressed, but the assert is no longer
serving its purpose.
I am resigning from my role as maintainer of the `rippled` codebase.
Please update repository permissions accordingly, prior to merging this pull request.
Thanks to everyone who has contributed, especially those whom I had the opportunity to closely collaborate with.
The AMM has an invariant for swaps where:
new_balance_1*new_balance_2 >= old_balance_1*old_balance_2
Due to rounding, this invariant could sometimes be violated (although by
very small amounts).
This patch introduces an amendment `fixAMMRounding` that changes the
rounding to always favor the AMM. Doing this should maintain the
invariant.

It can be difficult to make transaction breaking changes to low level
code because the low level code does not have access to a ledger and the
current activated amendments in that ledger (the "rules"). This patch
adds global access to the current ledger rules as a `std::optional`. If
the optional is not seated, then there is no active transaction.
The `rotateWithLock` function holds a lock while it calls a callback
function that's passed in by the caller. This is a problematic design
that needs to be used very carefully. In this case, at least one caller
passed in a callback that eventually relocks the mutex on the same
thread, causing UB (a deadlock was observed). The caller was from
SHAMapStoreImpl, and it called `clearCaches`. This `clearCaches` can
potentially call `fetchNodeObject`, which tried to relock the mutex.
This patch resolves the issue by changing the mutex type to a
`recursive_mutex`. Ideally, the code should be rewritten so it doesn't
hold the mutex during the callback and the mutex should be changed back
to a regular mutex.

* Amend `.codecov.yml` to disable coverage reporting of test sources
and explicitly set most parameters
* Increase codecov upload retry time to 210s (from 35s)
* Upgrade gcovr adding support for more coverage formats (lcov, clover, jacoco)
* Upgrade github actions in coverage workflow
* Explicitly disable codecov plugins (also removing `gcov` coverage, which is not
correctly handled by codecov https://github.com/codecov/feedback/issues/334)
This amendment, `fixPreviousTxnID`, adds `PreviousTxnID` and
`PreviousTxnLgrSequence` as fields to all ledger objects that did
not already have them included (`DirectoryNode`, `Amendments`,
`FeeSettings`, `NegativeUNL`, and `AMM`). This makes it much easier
to go through the history of these ledger objects.
Github Actions for the build/test jobs (nix.yml, mac.yml, windows.yml) will only run on branches that build packages (develop, release, master), and branches with names starting with "ci/". This is intended as a compromise between disabling CI jobs on personal forks entirely, and having the jobs run as a free-for-all. Note that it will not affect PR jobs at all.
When calculating reward shares, the amount should always be rounded
down. If the `fixUniversalNumber` amendment is not active, this works
correctly. If it is not active, then the amount is incorrectly rounded
up. This patch introduces an amendment so it will be rounded down.
This fixes a case where a peer can desync under a certain timing
circumstance--if it reaches a certain point in consensus before it receives
proposals.
This was noticed under high transaction volumes. Namely, when we arrive at the
point of deciding whether consensus is reached after minimum establish phase
duration but before having received any proposals. This could be caused by
finishing the previous round slightly faster and/or having some delay in
receiving proposals. Existing behavior arrives at consensus immediately after
the minimum establish duration with no proposals. This causes us to desync
because we then close a non-validated ledger. The change in this PR causes us to
wait for a configured threshold before making the decision to arrive at
consensus with no proposals. This allows validators to catch up and for brief
delays in receiving proposals to be absorbed. There should be no drawback since,
with no proposals coming in, we needn't be in a huge rush to jump ahead.
Remove the zaphod.alloy.ee hubs from the bootstrap and default configuration after 5 years. It has been an honor to run these servers, but it is now time for another entity to step into this role.
The zaphod servers will be taken offline in a phased manner keeping all those who have peering arrangements informed.
These would be the preferred attributes of a boostrap set of hubs:
1. Commitment to run the hubs for a minimum of 2 years
2. Highly available
3. Geographically dispersed
4. Secure and up to date
5. Committed to ensure that peering information is kept private
We do not currently enforce that incoming peer connection does not have
remote_endpoint which is already used (either by incoming or outgoing
connection), hence already stored in slots_. If we happen to receive a
connection from such a duplicate remote_endpoint, it will eventually result in a
crash (when disconnecting) or weird behavior (when updating slot state), as a
result of an apparently matching remote_endpoint in slots_ being used by a
different connection.
This amendment fixes an edge case where an empty DID object can be
created. It adds an additional check to ensure that DIDs are
non-empty when created, and returns a `tecEMPTY_DID` error if the DID
would be empty.
The witness server makes heavily use of the `account_tx` RPC command. Perf
testing showed that the SQL query used by `account_tx` became unacceptably slow
when the DB was large and there was a `marker` parameter. The plan for the query
showed only indexed reads. This appears to be an issue with the internal SQLite
optimizer. This patch rewrote the query to use `UNION` instead of `OR` and
significantly improves performance. See RXI-896 and RIPD-1847 for more details.
- Update container for Doxygen workflow. Matches Linux workflow, with newer GLIBC version required by newer actions.
- Fixes macOS workflow to install and configure Conan correctly. Still fails on tests, but that does not seem attributable to the workflow.
* telENV_RPC_FAILED is a new code, reserved exclusively
for unit tests when RPC fails. This will
make those types of errors distinct and easier to test
for when expected and/or diagnose when not.
* Output RPC command result when result is not expected.
We are currently using old version 0.6.2 of `xxhash`, as a verbatim copy and paste of its header file `xxhash.h`. Switch to the more recent version 0.8.2. Since this version is in Conan Center (and properly protects its ABI by keeping the state object incomplete), add it as a Conan requirement. Switch to the SIMD instructions (in the new `XXH3` family) supported by the new version.
This algorithm is about an order of magnitude faster than the existing
algorithm (about 10x faster for encoding and about 15x faster for
decoding - including the double hash for the checksum). The algorithms
use gcc's int128 (fast MS version will have to wait, in the meantime MS
falls back to the slow code).
* It is now an invariant that all constructed Public Keys are valid,
non-empty and contain 33 bytes of data.
* Additionally, the memory footprint of the PublicKey class is reduced.
The size_ data member is declared as static.
* Distinguish and identify the PublisherList retrieved from the local
config file, versus the ones obtained from other validators.
* Fixes#2942
The compilation fails due to an issue in the initializer list
of an optional argument, which holds a vector of pairs.
The code compiles correctly on earlier gcc versions, but fails on gcc 13.
Implement native support for Price Oracles.
A Price Oracle is used to bring real-world data, such as market prices,
onto the blockchain, enabling dApps to access and utilize information
that resides outside the blockchain.
Add Price Oracle functionality:
- OracleSet: create or update the Oracle object
- OracleDelete: delete the Oracle object
To support this functionality add:
- New RPC method, `get_aggregate_price`, to calculate aggregate price for a token pair of the specified oracles
- `ltOracle` object
The `ltOracle` object maintains:
- Oracle Owner's account
- Oracle's metadata
- Up to ten token pairs with the scaled price
- The last update time the token pairs were updated
Add Oracle unit-tests

| A | No stray dotted span-attribute key (only the derived resource keys may be dotted). |
| G | Attribute keys are `lower_snake_case` (`^[a-z][a-z0-9_]*$` per dot-segment) — no camelCase, UPPERCASE, or spaces. |
| F | No string literals as attribute keys or span-name arguments in `setAttribute`/`addEvent`/`span`/`rootSpan`/`childSpan` (`rootSpan` shares `span`'s `(cat, prefix, name)` signature). Attribute _values_ are exempt (runtime data); `*SpanNames.h` definitions and test files are exempt. |
| B | Every collector `spanmetrics.dimensions` name exists in the L1 key set. |
| C | Every Tempo span-filter tag exists in the L1 key set. |
| D | Every dashboard label resolves to an L1 span attribute, a native-metric label (L6, emitted by MetricsRegistry), or a Prometheus/Grafana builtin. TraceQL scope prefixes (`span.`/`resource.`/…) are stripped before the L1 lookup. |
| E | No dotted `xrpl.<domain>.<field>` attribute key in the runbook (only the L1 resource attrs `xrpl.network.*` may be dotted). Span names, filenames, OTel-standard keys, and metric labels are not flagged. |
| I | No string literals as **metric** instrument names or label keys — the mirror of Rule F. Applies to the name passed to an `XRPL_METRIC_*` macro or a `meter->Create*` factory and to the label _keys_ in its label set. Label _values_, descriptions, `*MetricNames.h`, `MetricMacros.h` and test files are exempt. Scoped by metric **family** (first underscore segment): declaring a constant opts that family in, so the metric surface can be converted subsystem by subsystem. Unconverted families warn as Rule L. |
| J | Metric instrument names follow the suffix conventions: `lower_snake_case`, no `xrpld_`/`xrpl_` prefix (the exporter adds it), a counter ends `_total`, a histogram ends `_us`/`_ms`/`_seconds`, a gauge does not end `_total`. The instrument **kind** is read from the emit site, never guessed from words in the name — so a multi-series gauge carrying units in its label values (e.g. `nodestore_state` observing `write_mean_us`) is not a violation. A name created through two different factories is itself reported as a kind conflict, since no suffix can be correct for both. |
| K | Every metric named in `docker/telemetry/workload/expected_metrics.json` resolves to a declared constant, so a rename in code cannot leave the workload validator asserting a name nothing emits. PromQL selectors (`m{label="v"}`) and exporter-appended histogram suffixes (`_bucket`/`_count`/`_sum`) are normalized away first; groups fed by another emit path (`statsd_gauges`, `statsd_counters`, `spanmetrics`) are out of scope by design. |
Rule F runs **unconditionally** (it is a purely syntactic check on the
call-sites and needs no `*SpanNames.h`), so a code path that calls
`SpanGuard::span`/`setAttribute` directly without ever defining a header is
| H | A namespace-qualified constant (e.g. `foo::bar::myKey`) used at a telemetry call-site is not defined in any `*SpanNames.h`. The constant should live in the proper header; defining it in-place bypasses rules A/G/F. Warns rather than fails — the argument may be a legitimately dynamic value, and the header may live on a later branch. Bare locals and `std::` names are not warned. |
| L | A literal metric name in a family that has no `*MetricNames.h` constants yet. Rule I's ratchet defers these instead of failing the build on the whole pre-existing metric surface at once; the warning keeps the outstanding conversion work visible rather than silently accepted. |
## Presence-gated
Every rule runs **only when the source files it needs are present** in the tree
and is otherwise skipped (printed as `SKIP: <rule> — <reason>`), never failed.
This keeps the check correct no matter how telemetry work is split across PRs —
a stacked chain, one large PR, or independent per-stage PRs where (for example)
the collector config lands before the dashboards. The collector/Tempo/dashboard/
runbook layers are introduced in later phases; on a branch without them, only

For info about how [API versioning](https://xrpl.org/request-formatting.html#api-versioning) works, including examples, please view the [XLS-22d spec](https://github.com/XRPLF/XRPL-Standards/discussions/54). For details about the implementation of API versioning, view the [implementation PR](https://github.com/XRPLF/rippled/pull/3155). API versioning ensures existing integrations and users continue to receive existing behavior, while those that request a higher API version will experience new behavior.
The API version controls the API behavior you see. This includes what properties you see in responses, what parameters you're permitted to send in requests, and so on. You specify the API version in each of your requests. When a breaking change is introduced to the `rippled` API, a new version is released. To avoid breaking your code, you should set (or increase) your version when you're ready to upgrade.

## API Version 3 (Beta)
API version 3 is currently a beta API. It requires enabling `[beta_rpc_api]` in the xrpld configuration to use. See [API-VERSION-3.md](API-VERSION-3.md) for the full list of changes in API version 3.
## API Version 2
API version 2 is available in `xrpld` version 2.0.0 and later. See [API-VERSION-2.md](API-VERSION-2.md) for the full list of changes in API version 2.
## API Version 1
This version is supported by all `rippled` versions. At time of writing, it is the default API version, used when no `api_version` is specified. When a new API version is introduced, the command line interface will default to the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
This version is supported by all `xrpld` versions. For WebSocket and HTTP JSON-RPC requests, it is currently the default API version used when no `api_version` is specified.
### Idiosyncrasies
## Unreleased
#### V1 account_info response
This section contains changes targeting a future version.
In [the response to the `account_info` command](https://xrpl.org/account_info.html#response-format), there is `account_data` - which is supposed to be an `AccountRoot` object - and `signer_lists` is returned in this object. However, the docs say that `signer_lists` should be at the root level of the reponse.
### Additions
It makes sense for `signer_lists` to be at the root level because signer lists are not part of the AccountRoot object. (First reported in [xrpl-dev-portal#938](https://github.com/XRPLF/xrpl-dev-portal/issues/938).)
-`account_tx`: Added an optional `delegate` request object to filter delegated transactions. The object requires `delegate_filter`, which must be either `actor` for transactions owned by the requested account but signed by another account, or `authorizer` for transactions signed by the requested account on behalf of another account. The optional `counter_party` account narrows the results to a specific signer/delegate for `actor` or a specific owner/delegator for `authorizer`. Malformed `delegate`, `delegate_filter`, and `counter_party` values return standard invalid field errors, and invalid account IDs return `actMalformed`.
When paginating delegate-filtered queries, a marker from a delegate-filtered query includes a `delegate` flag and is only valid for follow-up requests that also supply `delegate` (mixing marker conventions returns `invalidParams`). Because filtering is applied after the ledger scan, a page may contain fewer results than `limit` (possibly zero) while still returning a marker, so callers must continue until no marker is present.
In `api_version: 2`, the `signer_lists` field [will be moved](#modifications-to-account_info-response-in-v2) to the root level of the account_info response. (https://github.com/XRPLF/rippled/pull/3770)
-`ledger_entry`, `account_objects`: The `Delegate` ledger entry now includes an optional `DestinationNode` field, which stores the index into the authorized account's owner directory. This field is present on entries created after bidirectional directory tracking was introduced and may appear in RPC responses for those entries. ([#6681](https://github.com/XRPLF/rippled/pull/6681))
#### server_info - network_id
-`server_definitions`: Added the following new sections to the response ([#6321](https://github.com/XRPLF/rippled/pull/6321)):
-`TRANSACTION_FORMATS`: Describes the fields and their optionality for each transaction type, including common fields shared across all transactions.
-`LEDGER_ENTRY_FORMATS`: Describes the fields and their optionality for each ledger entry type, including common fields shared across all ledger entries.
-`TRANSACTION_FLAGS`: Maps transaction type names to their supported flags and flag values.
-`LEDGER_ENTRY_FLAGS`: Maps ledger entry type names to their flags and flag values.
-`ACCOUNT_SET_FLAGS`: Maps AccountSet flag names (asf flags) to their numeric values.
The `network_id` field was added in the `server_info` response in version 1.5.0 (2019), but it is not returned in [reporting mode](https://xrpl.org/rippled-server-modes.html#reporting-mode).
### Bugfixes
-`get_aggregate_price`: Duplicate entries in the `oracles` request array are now ignored. [#6586](https://github.com/XRPLF/rippled/pull/6586)
- Peer Crawler: The `port` field in `overlay.active[]` now consistently returns an integer instead of a string for outbound peers. [#6318](https://github.com/XRPLF/rippled/pull/6318)
-`ping`: The `ip` field is no longer returned as an empty string for proxied connections without a forwarded-for header. It is now omitted, consistent with the behavior for identified connections. [#6730](https://github.com/XRPLF/rippled/pull/6730)
- gRPC `GetLedgerDiff`: Fixed error message that incorrectly said "base ledger not validated" when the desired ledger was not validated. [#6730](https://github.com/XRPLF/rippled/pull/6730)

- Fixed a bug in `Forwarded` HTTP header parsing where the extracted IP address could be incorrect when no comma or semicolon delimiter follows the address. This could cause the server to misidentify a client's IP address when operating behind a reverse proxy. [#6529](https://github.com/XRPLF/rippled/pull/6529)
-`gateway_balances`: The `account` and `ident` fields now return an `invalidParams` error if the value is not a string, instead of an `internal` error. [#7655](https://github.com/XRPLF/rippled/pull/7655)

[Version 2.3.0](https://github.com/XRPLF/rippled/releases/tag/2.3.0) was released on Nov 25, 2024.
### Breaking changes in 2.3.0
-`book_changes`: If the requested ledger version is not available on this node, a `ledgerNotFound` error is returned and the node does not attempt to acquire the ledger from the p2p network (as with other non-admin RPCs). Admins can still attempt to retrieve old ledgers with the `ledger_request` RPC.
### Additions and bugfixes in 2.3.0
-`book_changes`: Returns a `validated` field in its response. ([#5096](https://github.com/XRPLF/rippled/pull/5096))
-`book_changes`: Accepts shortcut strings (`current`, `closed`, `validated`) for the `ledger_index` parameter. ([#5096](https://github.com/XRPLF/rippled/pull/5096))

-`account_nfts`: Fix issue where unassociated marker would return incorrect results. ([#5045](https://github.com/XRPLF/rippled/pull/5045))
-`account_objects`: Fix issue where invalid marker would not return an error. ([#5046](https://github.com/XRPLF/rippled/pull/5046))
-`account_objects`: Disallow filtering by ledger entry types that an account cannot hold. ([#5056](https://github.com/XRPLF/rippled/pull/5056))
-`feature`: Better error handling for invalid values of `feature`. ([#5063](https://github.com/XRPLF/rippled/pull/5063))

- In `Payment` transactions, `DeliverMax` has been added. This is a replacement for the `Amount` field, which should not be used. Typically, the `delivered_amount` (in transaction metadata) should be used. To ease the transition, `DeliverMax` is present regardless of API version, since adding a field is non-breaking.
- API version 2 has been moved from beta to supported, meaning that it is generally available (regardless of the `beta_rpc_api` setting).

-`ports` contains objects, each containing a `port` for the listening port (a number string), and a `protocol` array listing the supported protocols on that port.
- This allows crawlers to build a more detailed topology without needing to port-scan nodes.
- (For peers and other non-admin clients, the info about admin ports is excluded.)
- Clawback: The following additions are gated by the Clawback amendment (`featureClawback`). (https://github.com/XRPLF/rippled/pull/4553)

- For the `ledger_data` method, when all entries are filtered out, the `state` field of the response is now an empty list (in other words, an empty array, `[]`). (Previously, it would return `null`.)

removed from the [ledger subscription stream](https://xrpl.org/subscribe.html#ledger-stream), because it will no longer

## API Version 2
API version 2 is introduced in `rippled` version 2.0. Users can request it explicitly by specifying `"api_version" : 2`.
#### Removed methods
In API version 2, the following deprecated methods are no longer available: (https://github.com/XRPLF/rippled/pull/4759)
-`tx_history` - Instead, use other methods such as `account_tx` or `ledger` with the `transactions` field set to `true`.
-`ledger_header` - Instead, use the `ledger` method.
#### Modifications to JSON transaction element in V2
In API version 2, JSON elements for transaction output have been changed and made consistent for all methods which output transactions. (https://github.com/XRPLF/rippled/pull/4775)
This helps to unify the JSON serialization format of transactions. (https://github.com/XRPLF/clio/issues/722, https://github.com/XRPLF/rippled/issues/4727)
- JSON transaction element is named `tx_json`
- Binary transaction element is named `tx_blob`
- JSON transaction metadata element is named `meta`
- Binary transaction metadata element is named `meta_blob`
Additionally, these elements are now consistently available next to `tx_json` (i.e. sibling elements), where possible:
-`hash` - Transaction ID. This data was stored inside transaction output in API version 1, but in API version 2 is a sibling element.
-`ledger_index` - Ledger index (only set on validated ledgers)
-`ledger_hash` - Ledger hash (only set on closed or validated ledgers)
-`close_time_iso` - Ledger close time expressed in ISO 8601 time format (only set on validated ledgers)
-`validated` - Bool element set to `true` if the transaction is in a validated ledger, otherwise `false`
This change affects the following methods:
-`tx` - Transaction data moved into element `tx_json` (was inline inside `result`) or, if binary output was requested, moved from `tx` to `tx_blob`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
-`account_tx` - Renamed transaction element from `tx` to `tx_json`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
-`transaction_entry` - Renamed transaction metadata element from `metadata` to `meta`. Changed location of `hash` and added new elements
-`subscribe` - Renamed transaction element from `transaction` to `tx_json`. Changed location of `hash` and added new elements
-`sign`, `sign_for`, `submit` and `submit_multisigned` - Changed location of `hash` element.
#### Modification to `Payment` transaction JSON schema
When reading Payments, the `Amount` field should generally **not** be used. Instead, use [delivered_amount](https://xrpl.org/partial-payments.html#the-delivered_amount-field) to see the amount that the Payment delivered. To clarify its meaning, the `Amount` field is being renamed to `DeliverMax`. (https://github.com/XRPLF/rippled/pull/4733)
- In `Payment` transaction type, JSON RPC field `Amount` is renamed to `DeliverMax`. To enable smooth client transition, `Amount` is still handled, as described below: (https://github.com/XRPLF/rippled/pull/4733)
- On JSON RPC input (e.g. `submit_multisigned` etc. methods), `Amount` is recognized as an alias to `DeliverMax` for both API version 1 and version 2 clients.
- On JSON RPC input, submitting both `Amount` and `DeliverMax` fields is allowed _only_ if they are identical; otherwise such input is rejected with `rpcINVALID_PARAMS` error.
- On JSON RPC output (e.g. `subscribe`, `account_tx` etc. methods), `DeliverMax` is present in both API version 1 and version 2.
- On JSON RPC output, `Amount` is only present in API version 1 and _not_ in version 2.
#### Modifications to account_info response
-`signer_lists` is returned in the root of the response. In API version 1, it was nested under `account_data`. (https://github.com/XRPLF/rippled/pull/3770)
- When using an invalid `signer_lists` value, the API now returns an "invalidParams" error. (https://github.com/XRPLF/rippled/pull/4585)
- (`signer_lists` must be a boolean. In API version 1, strings were accepted and may return a normal response - i.e. as if `signer_lists` were `true`.)
#### Modifications to [account_tx](https://xrpl.org/account_tx.html#account_tx) response
- Using `ledger_index_min`, `ledger_index_max`, and `ledger_index` returns `invalidParams` because if you use `ledger_index_min` or `ledger_index_max`, then it does not make sense to also specify `ledger_index`. In API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4571)
- The same applies for `ledger_index_min`, `ledger_index_max`, and `ledger_hash`. (https://github.com/XRPLF/rippled/issues/4545#issuecomment-1565065579)
- Using a `ledger_index_min` or `ledger_index_max` beyond the range of ledgers that the server has:
- returns `lgrIdxMalformed` in API version 2. Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/issues/4288)
- Attempting to use a non-boolean value (such as a string) for the `binary` or `forward` parameters returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
#### Modifications to [noripple_check](https://xrpl.org/noripple_check.html#noripple_check) response
- Attempting to use a non-boolean value (such as a string) for the `transactions` parameter returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
# Unit tests for API changes
The following information is useful to developers contributing to this project:
API version 2 is available in `xrpld` version 2.0.0 and later. To use this API, clients specify `"api_version" : 2` in each request.
For info about how [API versioning](https://xrpl.org/request-formatting.html#api-versioning) works, including examples, please view the [XLS-22d spec](https://github.com/XRPLF/XRPL-Standards/discussions/54). For details about the implementation of API versioning, view the [implementation PR](https://github.com/XRPLF/rippled/pull/3155). API versioning ensures existing integrations and users continue to receive existing behavior, while those that request a higher API version will experience new behavior.
## Removed methods
In API version 2, the following deprecated methods are no longer available: ([#4759](https://github.com/XRPLF/rippled/pull/4759))
-`tx_history` - Instead, use other methods such as `account_tx` or `ledger` with the `transactions` field set to `true`.

- Binary transaction element is named `tx_blob`
- JSON transaction metadata element is named `meta`
- Binary transaction metadata element is named `meta_blob`
Additionally, these elements are now consistently available next to `tx_json` (i.e. sibling elements), where possible:

-`subscribe` - Renamed transaction element from `transaction` to `tx_json`. Changed location of `hash` and added new elements
-`sign`, `sign_for`, `submit` and `submit_multisigned` - Changed location of `hash` element.
## Modifications to `Payment` transaction JSON schema
When reading Payments, the `Amount` field should generally **not** be used. Instead, use [delivered_amount](https://xrpl.org/partial-payments.html#the-delivered_amount-field) to see the amount that the Payment delivered. To clarify its meaning, the `Amount` field is being renamed to `DeliverMax`. ([#4733](https://github.com/XRPLF/rippled/pull/4733))
- In `Payment` transaction type, JSON RPC field `Amount` is renamed to `DeliverMax`. To enable smooth client transition, `Amount` is still handled, as described below: ([#4733](https://github.com/XRPLF/rippled/pull/4733))
- On JSON RPC input (e.g. `submit_multisigned` etc. methods), `Amount` is recognized as an alias to `DeliverMax` for both API version 1 and version 2 clients.
- On JSON RPC input, submitting both `Amount` and `DeliverMax` fields is allowed _only_ if they are identical; otherwise such input is rejected with `rpcINVALID_PARAMS` error.
- On JSON RPC output (e.g. `subscribe`, `account_tx` etc. methods), `DeliverMax` is present in both API version 1 and version 2.
- On JSON RPC output, `Amount` is only present in API version 1 and _not_ in version 2.
## Modifications to account_info response
-`signer_lists` is returned in the root of the response. (In API version 1, it was nested under `account_data`.) ([#3770](https://github.com/XRPLF/rippled/pull/3770))
- When using an invalid `signer_lists` value, the API now returns an "invalidParams" error. ([#4585](https://github.com/XRPLF/rippled/pull/4585))
- (`signer_lists` must be a boolean. In API version 1, strings were accepted and may return a normal response - i.e. as if `signer_lists` were `true`.)
## Modifications to [account_tx](https://xrpl.org/account_tx.html#account_tx) response
- Using `ledger_index_min`, `ledger_index_max`, and `ledger_index` returns `invalidParams` because if you use `ledger_index_min` or `ledger_index_max`, then it does not make sense to also specify `ledger_index`. In API version 1, no error was returned. ([#4571](https://github.com/XRPLF/rippled/pull/4571))
- The same applies for `ledger_index_min`, `ledger_index_max`, and `ledger_hash`. ([#4545](https://github.com/XRPLF/rippled/issues/4545#issuecomment-1565065579))
- Using a `ledger_index_min` or `ledger_index_max` beyond the range of ledgers that the server has:
- returns `lgrIdxMalformed` in API version 2. Previously, in API version 1, no error was returned. ([#4288](https://github.com/XRPLF/rippled/issues/4288))
- Attempting to use a non-boolean value (such as a string) for the `binary` or `forward` parameters returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. ([#4620](https://github.com/XRPLF/rippled/pull/4620))
## Modifications to [noripple_check](https://xrpl.org/noripple_check.html#noripple_check) response
- Attempting to use a non-boolean value (such as a string) for the `transactions` parameter returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. ([#4620](https://github.com/XRPLF/rippled/pull/4620))
API version 3 is currently a **beta API**. It requires enabling `[beta_rpc_api]` in the xrpld configuration to use. To use this API, clients specify `"api_version" : 3` in each request.
For info about how [API versioning](https://xrpl.org/request-formatting.html#api-versioning) works, including examples, please view the [XLS-22d spec](https://github.com/XRPLF/XRPL-Standards/discussions/54). For details about the implementation of API versioning, view the [implementation PR](https://github.com/XRPLF/rippled/pull/3155). API versioning ensures existing integrations and users continue to receive existing behavior, while those that request a higher API version will experience new behavior.
## Breaking Changes
### Modifications to `amm_info`
The order of error checks has been changed to provide more specific error messages. ([#4924](https://github.com/XRPLF/rippled/pull/4924))
- **Before (API v2)**: When sending an invalid account or asset to `amm_info` while other parameters are not set as expected, the method returns a generic `rpcINVALID_PARAMS` error.
- **After (API v3)**: The same scenario returns a more specific error: `rpcISSUE_MALFORMED` for malformed assets or `rpcACT_MALFORMED` for malformed accounts.
### Modifications to `ledger_entry`
Added support for string shortcuts to look up fixed-location ledger entries using the `"index"` parameter. ([#5644](https://github.com/XRPLF/rippled/pull/5644))
In API version 3, the following string values can be used with the `"index"` parameter:
-`"index": "amendments"` - Returns the `Amendments` ledger entry
-`"index": "fee"` - Returns the `FeeSettings` ledger entry
-`"index": "nunl"` - Returns the `NegativeUNL` ledger entry

For the latest release candidate, choose the `release` branch.
### Linux
```
git checkout release
```
The Ubuntu Linux distribution has received the highest level of quality
assurance, testing, and support. We also support Red Hat and use Debian
internally.
Our Linux CI tooling is distro-independent and uses a Nix-based environment, so it should be possible to build on other Linux distributions as well, although we have not tested them.
### macOS
Many `xrpld` engineers use macOS for development.
The minimum supported version is macOS 15 (Sequoia).
CI testing is done in macOS 26 (Tahoe), but the build defaults `CMAKE_OSX_DEPLOYMENT_TARGET` to 15.
### Windows
Windows is used by some engineers for development only, and is not recommended
for production use.
## Steps
### Branches
For the latest set of untested features, or to contribute, choose the `develop`
branch.
```
```bash
git checkout develop
```
## Minimum Requirements
For a release candidate, choose the relevant release branch, e.g.
`release/3.2.x`.
See [System Requirements](https://xrpl.org/system-requirements.html).
```bash
git checkout release/3.2.x
```
Building rippled generally requires git, Python, Conan, CMake, and a C++ compiler. Some guidance on setting up such a [C++ development environment can be found here](./docs/build/environment.md).
- [Python 3.7](https://www.python.org/downloads/)
- [Conan 1.55](https://conan.io/downloads.html)
- [CMake 3.16](https://cmake.org/download/)
`rippled` is written in the C++20 dialect and includes the `<concepts>` header.
The [minimum compiler versions][2] required are:
| Compiler | Version |
|-------------|---------|
| GCC | 11 |
| Clang | 13 |
| Apple Clang | 13.1.6 |
| MSVC | 19.23 |
### Linux
The Ubuntu operating system has received the highest level of
quality assurance, testing, and support.
Here are [sample instructions for setting up a C++ development environment on Linux](./docs/build/environment.md#linux).
### Mac
Many rippled engineers use macOS for development.
Here are [sample instructions for setting up a C++ development environment on macOS](./docs/build/environment.md#macos).
### Windows
Windows is not recommended for production use at this time.
- Additionally, 32-bit Windows development is not supported.
- Visual Studio 2022 is not yet supported.
- rippled generally requires [Boost][] 1.77, which Conan cannot build with VS 2022.
- Until rippled is updated for compatibility with later versions of Boost, Windows developers may need to use Visual Studio 2019.
After you have a [C++ development environment](./docs/build/environment.md) ready with Git, Python, Conan, CMake, and a C++ compiler, you may need to set up your Conan profile.
Once your [development environment](./docs/build/environment.md) is ready, set
Conan up for this repository:
These instructions assume a basic familiarity with Conan and CMake.
If you are unfamiliar with Conan, then please read [this crash course](./docs/build/conan.md) or the official [Getting Started][3] walkthrough.
You can then build and test as usual, with the generated `xrpld` binary containing the sanitizer instrumentation. When you run it, it will report any sanitizer errors it detects in the console output.
See [Sanitizers docs](./docs/build/sanitizers.md) for more details.
## Options
| Option | Default Value | Description |
| --- | ---| ---|
| `assert` | OFF | Enable assertions.
| `reporting` | OFF | Build the reporting mode feature. |
| `coverage` | OFF | Prepare the coverage report. |
| `tests` | ON | Build tests. |
| `unity` | ON | Configure a unity build. |
| `san` | N/A | Enable a sanitizer with Clang. Choices are `thread` and `address`. |
If your compiler version is recent enough to have removed `std::result_of` as
part of C++20, e.g. Apple Clang 15.0, then you might need to add a preprocessor
definition to your build.
#### ERROR: Package not resolved
If you're seeing an error like `ERROR: Package 'snappy/1.1.10' not resolved: Unable to find 'snappy/1.1.10#968fef506ff261592ec30c574d4a7809%1756234314.246' in remotes.`,
please [set Conan up](#set-up-conan) so the `xrplf` remote is configured, or re-run `conan export` for [patched recipes](./docs/build/advanced_conan.md#patched-recipes).
### `protobuf/port_def.inc` file not found
If `cmake --build .` results in an error due to a missing a protobuf file, then
you might have generated CMake files for a different `build_type` than the
