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.
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.
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.

Bring the hardened OTel naming check (Rule E fix + 71 tests) and the phase 1-6
convention work forward into phase 7 (native metrics).
Conflict resolution:
- 05-configuration-reference.md: kept phase-7's native-OTLP metrics story
(server=otel, /v1/metrics) over phase-6's superseded StatsD scrape job, in
prose form (no code block).
- ordering.txt/loops.txt: regenerated via generate.py (not hand-edited).

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.

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.

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
broken/partial traces; pinning at 1.0 with a ParentBased sampler keeps
decisions coherent across the network. Volume reduction is delegated to
collector-side tail sampling.

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).

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.
