The $xrpl_work_item variable's description carried a real ticket id as its
example. The filter needs no example, so the id is gone and the wording stays.
The runbook's nodestore_state table kept AppMetricGauges.cpp as the source
column, which is where those gauges are actually registered on every branch
in the chain; the incoming side named MetricsRegistry.cpp, which registers
none of them. Took the incoming side's clearer wording for the sweep row.

StatsDCollector test kept both sides: this branch's onCollectionReady() call,
which enables polling and only exists from here on, followed by the upstream
branch's control assertion that reads the resulting datagram.

Both doc indexes kept this branch's 09-data-collection-reference.md rows,
which only exist here, and dropped every secure-OTel.md reference because
the upstream branch removed that file. No dangling link remains.

SpanGuardScope.cpp kept both includes: each side added one and both symbols
are used in the merged test.

unl_expiry_days subtracted two NetClock time points, whose rep is uint32_t, so
the subtraction wrapped before the duration_cast ran. A list expired by one day
read about +49709 days. The panel is green above 30 while its own description
promises red at expiry, so an expired validator list rendered healthy.
daysUntil() widens both endpoints to int64_t first, which makes the wrap
impossible rather than checked for. It deliberately does not clamp at zero: a
negative reading is the signal that expiry has passed. A config-listed list,
which uses time_point::max(), now reports positive infinity, because any finite
sentinel could not be told apart from the wrap this removes. -1 keeps its
existing meaning of no published list fetched.
The sweep counter told a second story it could not support. It counted every
entry the 1-minute sweep evicted, including acquisitions that had already
completed or failed and were merely still in the map. Those were counted when
they ended, so the metric buried the wasteful case in ordinary cleanup while
the runbook, the reference doc and the panel description all described only the
unfinished population. It now counts what those three already claimed.
isComplete()/isFailed() are used rather than isDone(), which is protected on
TimeoutCounter and not callable here.
The document is internal and is kept outside the repo instead.
This also removes every link to it: the document-index rows in
OpenTelemetryPlan.md and 08-appendix.md, its node, edge and style lines in the
plan's Mermaid map, its own section in OpenTelemetryPlan.md, and the two
cross-reference notes in 02-design-decisions.md and 05-configuration-reference.md.
The attribute table conflicted because this branch had added the fee and
sequence rows and widened tx_type's set-on list. Kept those, and dropped the
suppressed row the incoming side removed.
The note said the suppressed attribute is set on both outcomes. That attribute
is gone, and a duplicate produces no span, so the note now says where the
duplicate count lives instead.
tx.receive no longer sets it, and it is no longer a spanmetrics dimension, so
the attribute tables, the span-scope list and the Prometheus label list all
named something that is not emitted. The reduce-relay suppressed_peers gauge is
a different thing and stays.
The steps described setting a suppressed attribute on a dropped duplicate. The
span is now created after the duplicate check, so there is no span on that path.
The tx.receive span is created after the duplicate check, so it carries no
suppressed attribute and a dropped copy produces no span at all. How many were
dropped is the transactions_duplicate traffic category.
Brings the MetricsRegistry split onto this branch. The pipeline half is now
xrpl::telemetry::MetricsRegistry in libxrpl; the observable gauges are
xrpl::telemetry::AppMetricGauges in xrpld.
This branch had added its own instrumentation to the pre-split class, so the
merge had to route each addition to the correct half:
- The thirteen gauges added here -- amendment block, cache hit-rate detail,
clock skew, job-queue saturation, ledger quorum publish, peer ledger supply,
rotation state, slot census, stall events, sync acquire, sync state, UNL
quorum, and the cache lock-hold observer -- all land on AppMetricGauges,
reading the core's meter and validation tracker through it.
- The pipeline additions stay in libxrpl: the consensus round-duration and
rotation-phase histogram views, the malloc-trim and dns/dial latency bucket
ladders, the job-stall counter, and the switch from literal metric names to
the MetricNames.h constants.
Git detected the pre-split MetricsRegistry.cpp and .h as renames of the gauge
files, so both sides' pipeline changes initially landed in the gauge half. They
were moved back, and the result was audited by inventory: every method
definition, instrument creation, view registration, and emitted string from
either side is present, with identical multiplicity.
MetricNames.h moves to include/xrpl/telemetry/ alongside the core. It has no
includes of its own and its two sibling name headers already live there, so
keeping it under src/ would leave an xrpld path in libxrpl's dependency
surface. Nineteen files follow it.
incrementStateChanges() stays removed. The labelled state_changes_total{from,to}
counter this branch introduced replaces it, and the test asserting the method is
absent is kept -- an unlabelled instrument alongside the labelled one would give
Prometheus two conflicting versions of one metric name.
Two tests that drove startAsyncGauges() against a mock ServiceRegistry are
dropped: xrpl_tests links only xrpl.libxrpl and cannot reach the gauge class.
Levelization regenerated. Both xrpld.telemetry loops become bidirectional
rather than one-way; neither is new.
MetricsRegistry did two jobs. It owned the OTel metrics pipeline, and it
registered the observable gauges whose callbacks read live application
services. The second job is what made the whole class xrpld-tier, so the
pipeline's lifecycle -- the recording() gate and the stop() teardown that
closes a use-after-free window -- could not be unit-tested in xrpl_tests.
Split it in two:
- xrpl::telemetry::MetricsRegistry (libxrpl) owns the exporter, provider,
meter, the 16 synchronous instruments, recording(), stop(), and the
record*/increment* methods.
- xrpl::telemetry::AppMetricGauges (xrpld) owns the 19 observable gauges
and their callbacks, holding a reference to the core and to the
ServiceRegistry.
MetricMacros.h and ValidationTracker move with the core. The macros need
only recording() and meter(), both core members; the core holds a tracker
by value, and a libxrpl header cannot include one from src/.
ApplicationImp owns both objects and sequences them. The core is built in
the member-init list, so every synchronous instrument exists before any
subsystem can record one. The gauges are armed once overlay_ exists, the
last service their callbacks read. Shutdown detaches the gauge callbacks
before the core drops the provider, and each shutdown step is isolated so
a failure in one cannot skip the others.
That detach call is new. detachCallbacks() had no callers, and the flag it
sets is read by the gauge callbacks but can no longer be written by the
core, so the caller now has to make the ordering explicit.
The telemetry module links xrpl.libxrpl.core and xrpl.libxrpl.protocol
PUBLIC: ValidationTracker.h takes a LedgerIndex and MetricMacros.h takes a
ServiceRegistry, both in interfaces a consumer compiles against.
Adds a MetricsRegistry gtest that drives an enabled core with telemetry on
and pins the recording() gate, stop() leaving the registry inert, and
stop() being idempotent. The libxrpl test tree no longer depends on
xrpld.telemetry at all, and the two CMake workarounds that compiled xrpld
sources into xrpl_tests are gone.
Documentation and dashboard source links follow the code to their new
paths, split between the two classes by which one now defines each metric.
Review follow-up on the freshen lock-hold fix:
- Drop host names, dates and one-site figures from the new comments,
harness notes and docs; explain the mechanism in general terms.
- RotationPhase stores its stage and cache labels as owned std::string,
not std::string_view: the ctor still takes views so the label
constants pass without a copy, but a member view would dangle if a
caller ever passed a temporary. freshenCache/recordFreshen take the
cache name by std::string_view (read-only, call-scoped).
- The new DatabaseRotating test called fetchNodeObject through the
derived type, whose private override hides the public base method;
call it through Database& instead. This was the dev-box build break.
- freshenCache reports the exact fetched count when a health abort cuts
it short, and stops labelling the per-partition hold 'getKeys'.
- Remove a [[maybe_unused]] that silenced no warning (the build sets
-Wno-unused-parameter and disables misc-unused-parameters).
