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.
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.
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.
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.
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.
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.
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
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 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.
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.
`.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.
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.
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.
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.
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

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.
