The list mirrors the collector's spanmetrics dimensions, and that dimension is
gone. The reduce-relay and squelch counters keep their own names, which are a
different thing.
The workload README contradicted itself on --skip-loki: one bullet said CI always
passes it and so the two log-correlation checks are never exercised, another said
the workflow no longer passes it. The workflow mentions the flag nowhere, so the
first was the stale half.
Other claims checked against the tree and corrected:
- both the README and the plan doc described the push trigger as filtered on
branch names. The workflow has no branches filter, deliberately, because
GitHub ANDs branches with paths
- the plan doc printed 6 of the workflow's 12 paths globs, and claimed the
workflow was 367 lines against an actual 451. The glob block is now generated
from the workflow, and the line count dropped rather than restated
- rpcNOT_SUPPORTED does not exist anywhere in the tree. The symbol is
RpcNotSupported, and the refusal sites are RipplePathFind.cpp:59-60 and
PathFind.cpp:50-51, not :48-49 and :39
- RCLConsensus.cpp:666 and :663 are not log or event lines; the tx.included event
is at :720 and the per-transaction debug log at :715
- LedgerMaster.cpp:463 is fixIndex, not the ledger.store span, which is at :470
- ServerHandler.cpp:705 is inside makeJsonError; processRequest is at :718
- file counts: docker/telemetry/workload/ is 25 files, include/xrpl/telemetry/ 13
- the optional-span bullet named five causes covering 10 of 16 entries, omitting
the txq.* family and the WebSocket handshake
- the /api/v1/series choice was attributed to stale StatsD gauges; this harness
runs no StatsD
A line number in run-full-validation.sh was cited in five places and drifts on
every edit to that file, so those now name the file only. The keygen helper's
header records what production does instead -- validator-keys-tool create_keys
then create_token, keeping the master key off the node -- and why a disposable
cluster does not.
The harness contract described how path-finding load came to be absent rather
than why it is absent. The load exists on no branch before this one, so a squash
merge publishes no revision that ever issued it: the 2026-08-25 date resolves
nowhere, and 'removing it', 'used to satisfy' and 'has now cleared' compare
against a state a reader cannot reach.
- README: state that DEFAULT_WEIGHTS carries no ripple_path_find entry, and give
the error floor as what WOULD happen if it did, rather than what removing it
fixed. 'Putting it back' becomes 'Enabling it'.
- expected_spans.json: the pathfind.request and pathfind.compute notes, and both
hierarchy skip_reasons, now put the span's presence in the conditional -- the
parent would appear if the RPC were issued, because the ScopedSpanGuard at
RipplePathFind.cpp:35 sits above the rpcNOT_SUPPORTED guard at :48-49.
- expected_metrics.json: the rpc_method_errored_total, pathfind_fast and
pathfind_full notes drop the date and keep both independent reasons the
metrics stay absent.
- regression-thresholds.json: span.ledger.store 'is excluded from' the gated
surface rather than 'was removed from' it.
The reasoning is unchanged: pathfinding is off because Config.cpp:725-726 zeroes
pathSearchMax when [validation_seed] is present, a refused call still exports an
error span, and at a 3% weight that is a ~3% STATUS_CODE_ERROR floor.
Documentation and JSON note strings only, no behaviour change.
Every node the harness starts is a validator, and validators disable
pathfinding: Config.cpp:725-726 zeroes pathSearchMax whenever a
[validation_seed] or [validator_token] section is present, and
run-full-validation.sh writes [validation_seed] into every generated node
cfg (:308) with no [path_search] section to put the default back. So
doRipplePathFind refused every call at RipplePathFind.cpp:48-49 and the
3% ripple_path_find weight bought no coverage at all.
It was not free either. The pathfind.request guard is constructed at
RipplePathFind.cpp:35, above that refusal, so each refused call still
exported a span, and the enclosing rpc.command.ripple_path_find span
carried rpc_status=error. That put a steady 3% error floor into
span_calls_total for STATUS_CODE_ERROR: any error-rate threshold derived
from harness data before this change was measuring the harness rather
than xrpld, and needs re-deriving.
Removing the load makes pathfind.request unreachable, so it moves from
required to optional in expected_spans.json; without that the span check
would fail on every run. Three notes in that file and three in
expected_metrics.json made claims that are now false, two of them citing
line numbers this commit deletes; all six are corrected. The runbook
required/optional count moves 26/15 to 25/16.
Two facts a future reader needs.
First, the weights previously summed to 103, not 100, so every percentage
the docstring stated was wrong: health checks were really 38.8%, not 40%.
Dropping the 3 makes the sum exactly 100 and every stated percentage
correct for the first time. expected_spans.json also carried live
arithmetic off the old total, "25/103 ... roughly 43%", now 25/100 and
42%.
Second, baselines/baseline-timings.json was captured WITH this load. Only
span.rpc.ws_message p50/p95/p99 of the 25 gated keys sees the RPC mix,
and their trip points sit 3.1x to 5.9x above baseline, so the gate will
not fire. But a timing baseline is workload-specific and its profile
field still reads full-validation, so nothing will flag the drift:
refresh it from the next CI run's timings artifact.
Pathfinding now has no coverage in this harness at all. The workload
README section "Pathfinding is not exercised" records that cost, the
manual verification route, and a four-step restore recipe in which steps
1 and 2 alone only reinstate the error floor.
validate_metrics and validate_spans only ever run one direction: read the
contract, ask the backend whether each listed name exists. Nothing looked the
other way, so a metric family or span name the contract omitted was invisible
by construction. Both emitted inventories were already being fetched for the
CI log and neither was compared back, which is how a 345 family metric gap and
7 unknown span names went unnoticed.
Add two reverse checks, metric.reverse_coverage and span.reverse_coverage.
Each names every emitted family the contract never mentions, sorted, one per
line, with counts in the report details.
Warn only, by design. passed is hardcoded True in a single shared builder, so
an unaccounted name cannot turn CI red: downstream branches legitimately add
telemetry an upstream contract has not seen yet, and a hard failure would
redden all of them for doing the right thing.
Bulk families are accounted for declaratively. A new top level
accounted_patterns list in expected_metrics.json holds anchored regexes with a
written reason each, covering the 105 per job type queue gauges, the 70 per job
type histogram families, the 228 overlay per category traffic families, and the
Prometheus scrape plumbing that is not xrpld telemetry. Job type shapes are
reduced structurally because every job type name lowercases to letters only;
traffic categories are enumerated instead, because they contain underscores and
a structural pattern there would swallow unrelated names. Anything outside
these shapes still surfaces.
Exporter shapes are folded before matching, so a histogram triple is accounted
for by an entry written for its base family and is never reported as three
separate gaps. Spans need no pattern list: the reverse check reuses the same
matcher the forward check uses, so a glob such as rpc.command.* covers every
command it expands to, and an optional entry still counts as known.
Also fix the diagnostic these checks feed on: both emitted lists were logged as
a single Python list repr, about 15 kB on one line for 422 families, unreadable
and impossible to compare between runs. Both now print one name per line.
_metric_check_targets now selects groups by testing that the value is an
object, rather than by excluding two key names, so a non group top level key
cannot break it. Output is byte identical: 79 metric plus 5 label checks, same
names in the same order.
The assert / do-not-assert decisions in expected_metrics.json and
expected_spans.json were all correct, but several recorded reasons were not.
Pathfinding is disabled outright on every harness node: Config.cpp:725-726
zeroes pathSearchMax whenever a [validation_seed] or [validator_token] section
is present, run-full-validation.sh writes [validation_seed] for every node and
has no [path_search] override, and both handlers return rpcNOT_SUPPORTED
before constructing a PathRequest.
- pathfind_full_milliseconds no longer claims a probabilistic path, nor
prescribes an explicit ledger index, which cannot help: the config gate
fires before the ledger parameter is read.
- pathfind_fast_milliseconds keeps its hasCompletion argument but now leads
with the config gate, which is the operative blocker.
- The pathfind.compute and pathfind.discover notes and the
pathfind.request to pathfind.compute skip reason no longer blame missing
liquidity. pathfind.update_all now records why its request list stays empty.
- statsd_gauges states the arming precondition: a beast gauge is only as safe
as an observable gauge when its object exists before Application.cpp:1570,
where onCollectionReady arms the registered gauges exactly once.
- Alert wiring claims softened: every rule in rules.yaml is paused.
- The per job type gauge group loses its bogus poll bandwidth reason, and its
regex claim is corrected: there is no running state regex, so 30 of those
gauges have no consumer at all.
- overlay_peer_disconnects has one query consumer, not two.
- Cloud dashboard copies dropped from consumer counts: that tree is ignored by
git and has no tracked files.
- rpc_method_errored_total explains that a refused RPC is a normal return, not
a throw, so the refusals above do not make it fire.
- 09-data-collection-reference.md no longer claims a Prometheus name query in
expected_metrics.json.
No behaviour change: the flattened check name list is byte identical.
Dashboards and alert rules reference 186 metrics; the harness asserted 57.
Excluding the 107 per-category overlay-traffic expansions, the meaningful
gap was 20 names. This closes it under the contract file's own doctrine:
assert only what the workload guarantees, and record the rest with a
precise reason.
Asserted 18, taking the metric checks from 61 to 79 and the whole metric
phase from 66 to 84. No pre-existing check name or position changes.
statsd_gauges gains the nine state_accounting_* siblings of the one member
already asserted, plus the two NodeFamily full-below-cache gauges and
overlay_peer_disconnects. All twelve rest on one mechanism the group
description now spells out: on the OTel path a beast gauge is an
Int64ObservableGauge, every instance self-registers in its constructor,
onCollectionReady arms all of them unconditionally, and the armed callback
Observes on every export cycle whether or not set was ever called, so the
series exist at 0. The state_accounting family is set in one unconditional
block in NetworkOPsImp::collectMetrics, and full_transitions is the input
to the NodeStateFlapping alert rule, so the alert's own signal had been
going unverified.
A new job_queue_per_type_gauges group asserts the six per-job-type gauges
that a panel or a rule names literally, jobq_manifest_waiting among them
as the ManifestJobQueueConvoy rule's input. The description records why
those six and not all 105: the guarantee is identical for every
non-special job type, so the discriminator is consumer coverage, and the
remaining names are only reached through topk queries over the family that
do not depend on any single type being present.
Recorded four more in not_asserted rather than asserting them.
pathfind_fast_milliseconds is unreachable for this workload, not merely
rare: reportFast fires only from the doCreate fast pass, which is guarded
by !hasCompletion(), and both ripple_path_find entry points construct the
request with a completion function. Only the path_find subscription
reaches it, and the generator does not use it.
pathfind_full_milliseconds is reachable but only one ledger close after
the request, through PathRequestManager::updateAll, and nothing in the
harness arranges or checks that, so the guarantee is probabilistic.
warn_total and drop_total are resource-manager meters gated on a consumer
crossing the warn or drop threshold; their rpc-pathfinding panels are
correct and render empty only because the condition has not occurred,
which is worth stating because both were briefly mis-read as phantoms.
Runbook check counts updated to match.
RPC Response Size on rpc-pathfinding said its p95 was computed "over the
dashboard rate interval", but the query hardcodes [5m]. Every other panel on
that dashboard with a hardcoded [5m] -- RPC Response Time, RPC Response Time
Distribution, both Pathfinding duration panels, the gRPC latency panel and
Pathfinding Compute Duration -- says "over 5 minutes". Matched the clause to
the query. The same edit was applied to the local grafanacloud copy so the
two stay identical; that tree is gitignored, so it is not in this commit.
The io_latency group in expected_metrics.json claimed "all 6 panels that
query it". That 6 was a raw string-occurrence count over the dashboards and
included two panel descriptions. Verified truth: two distinct panels query
the metric, ledger-data-sync "I/O Scheduler Latency p95" and node-health
"I/O Latency", each mirrored in a grafanacloud copy, plus one alert rule in
grafana/provisioning/alerting/rules.yaml. Stated that instead of a count.
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.
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.
Strip xrpld_ prefix, lowercase beast::insight names, and replace
traces_span_metrics_ with span_ in all remaining tracked files:
alert rules, integration tests, workload validation, TESTING.md,
OpenTelemetryPlan docs, code comments, and config templates.

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).

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).
- Add a high-TPS txq-burst workload phase to force fee escalation (drives txq.*).
All facts verified against the *SpanNames.h headers and a live xrpld node +
collector (Tempo service.name=xrpld, tx.preflight attrs [stage,ter_result,tx_type],
279 xrpld_ Prometheus metrics and zero rippled_).

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.
