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.

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.
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.

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.

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.

Move the standalone External Dashboard Parity design spec out of
docs/superpowers/ (which the project guidelines say not to create) and into
an appendix of OpenTelemetryPlan/06-implementation-phases.md, so the phase
plan is self-contained. Repoint the 10 "Source" links in the phase 3/4/7
task lists to the new appendix anchor.

Point the workload validation uid list and implementation-phases doc at
the renamed bare dashboard uids.

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.
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.

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).

The two "Spans Produced" tables in 06-implementation-phases.md (added by the
Phase 4 consensus work) listed span ATTRIBUTE keys in the dotted
xrpl.consensus.* / ledger.seq / mode.old form. Convert them to the underscore
convention, matching the authoritative ConsensusSpanNames.h constants
(consensus_round, ledger_seq, consensus_mode, consensus_round_id,
consensus_ledger_id, consensus_result, mode_old/new, agree_count/disagree_count,
etc.). Span NAMES in column 1 stay dotted (rule 5). Every key verified to exist
as a constant in ConsensusSpanNames.h / SpanNames.h.

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.
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`.
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.
