The file_storage extension was added to otel-collector-config.yaml, which
every stack mounts. That made the extension mandatory: the collector image
runs as 10001:10001 and ships no writable directory, so any stack without a
prepared volume would fail to start rather than merely lose offsets. The
workload-validation stack mounts this same config and has no such volume.
Offset persistence is only useful where logs outlive a restart. The workload
harness creates a fresh log directory per run, so it has nothing to resume
from. Move the extension, the receiver's storage reference and the extended
service.extensions list into otel-collector-filestorage.yaml, layered as a
second --config by the developer stack alone. The base config keeps
start_at: beginning, which is what actually fixes the reported defect, and
stays self-sufficient for every other stack.
Verified against the pinned collector image: the base config validates and
runs on its own with no volume mounted and still ingests a line written
before startup; base plus overlay validates, preserves the base receiver's
operators through the merge, and re-ingests that line zero times on a second
run against the same volume.
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 four job-latency panels on node-health declared milliseconds while
querying `job_running_us` / `job_queued_us`, which record microseconds
(MetricsRegistry records the raw value, and the instrument description
says microseconds). Every reading was therefore a thousand times too
large: the p95 for acceptLedger, 241495us, rendered as "241 sec"
instead of 241ms. job-queue.json already read these same metrics as
microseconds, so the two dashboards disagreed by 1000x on identical
data. Switch node-health to microseconds to match.
Also replace the generic `ops` and `cps` units, which Grafana renders
as the literal "ops/s" and "counts/s", with custom-suffix units naming
what each panel counts -- messages, fetches, calls, mismatches.
Two panels plot more than one quantity on a single axis, which no
single unit can describe. Give each series its own unit through field
overrides: reads per second beside two queue depths on NuDB Read
Pressure, and ledgers beside fetches on Ledger Close Rate, the latter
on a right-hand axis.
State Duration Rate plots a seconds-per-second time share, which can
exceed 1.0 and so is not a percentage; label it as the ratio it is.
The normalised share already exists as its own panel.
Queries are unchanged; the values were already correct.
Alongside, bring the touched panels up to the dashboard guidelines and
hoist the stat panels above the fold.
Grafana renders `unit: "ops"` as the literal string "ops/s", so every
rate panel read as "operations per second" regardless of what it
actually counted. `Ledger Build Rate` showed "0.258 ops/s" where the
value is one ledger every 3.9s -- the number was right, the unit was
meaningless.
Replace the generic units with Grafana custom-suffix units naming the
quantity, following the existing `suffix:/hr` and `si:drops` precedent
in this repo. Nine of these are `stat` panels with no axis, so the unit
string was the only text a reader ever saw.
Also switch the two trusted/untrusted piecharts and the transaction
path piechart from rate() to increase(): a per-slice "per second"
reading is not a share of a total, counts in the window are.
Queries are unchanged apart from those three; the values were already
correct.
Alongside, bring the touched panels up to the dashboard guidelines:
tooltip mode/sort/max-height, 30-minute null spanning, and axis labels
in title case. Hoist the stat panels above the fold on
ledger-operations and rpc-performance.
Panels that a later branch in this chain removes are deliberately left
alone -- fixing them would only add merge conflicts.
Add current_ledger_seq / current_ledger_hash to the tx.process, tx.receive,
and txq.enqueue span-reference rows, correct the txq.enqueue parent note
(parents to tx.process on the submission path via explicit context; a root on
the open-ledger rebuild path), and add a "Correlating a transaction to the
ledger it was worked on" recipe joining the txID-keyed tx/txq spans to the
ledger trace via current_ledger_seq.

These inbound peer-message entry points (kConsumer) used span(), which
inherits whatever span is active on the peer thread — including a leaked
tx.receive scope — so validations/proposals were wrongly nested under
unrelated transaction traces. rootSpan() starts a fresh trace root.

Replace the TxQ Accept Status piechart on the Transaction Overview
dashboard with a state-timeline showing each node's applied fraction of
TxQ accepts (applied / applied+failed) over time, colored by threshold
(green >=0.9, yellow >=0.7, red below). Remove the now-orphaned
txq_status template variable (the piechart was its only consumer) and
document the panel in the telemetry runbook.

The spanmetrics connector had no namespace, so it emitted traces_span_metrics_*
metric names by default. The span dashboards and docs are renamed to query
span_* names; this is only correct if the connector emits them too, so add
namespace: "span" to the spanmetrics connector. Both sides change together:
renaming the dashboards without the namespace (or vice versa) would break the
pipeline. Matches the phase9 collector config.

The phase7 OTelCollector::formatName lowercases and strips names, emitting
snake_case metrics with no xrpld_ prefix. The native Grafana dashboards and
the telemetry docs still queried the old xrpld_CamelCase names, so they were
broken against their own pipeline. Rename every metric name to match what the
code emits: drop the xrpld_ prefix and lowercase the remainder. The two job
histograms also drop the redundant 'duration' word (job_queued_us,
job_running_us) to match the phase9 forms. Add havetxset to the cspell
dictionary since the lowercased metric name no longer word-splits.

The collector's log ingestion used a container path named after the old
`rippled` binary and defaulted its host mount to a location that either
needed root or diverged from where the telemetry configs actually write.
Consolidate on one accessible log root:
- container mount target renamed /var/log/rippled -> /var/log/xrpld
- filelog glob -> /var/log/xrpld/*/debug.log
- compose mount source defaults to the repo-relative ./data/logs
(user-owned, no root), overridable via XRPLD_LOG_DIR
- devnet telemetry cfg writes to data/logs/devnet/debug.log so it lands
one subdir below the mount root and matches the glob
- integration-test.sh sets XRPLD_LOG_DIR to its own workdir
- docs/runbook/task-list updated to match
The default xrpld config (cfg/xrpld-example.cfg) is intentionally left
untouched.

- Correct log-timestamp examples to real Logs::format() output
(2024-Jan-15 10:30:45.123456 UTC) in docs, TESTING.md, and reference.
- Update Loki to v3.4.2 and switch the collector exporter to
otlphttp/loki on the native /otlp endpoint (docs + task list).
- Make the collector log-mount path configurable via XRPLD_LOG_DIR.
- Remove implementation-phase references from shipped config/script
comments, keeping the functional descriptions.

- Add PathFinding Spans section to the runbook Span Reference and
remove the incorrect "not emitted / later-phase" annotations:
pathfind.request/compute/discover/update_all are emitted since
Phase 2 (upstream of Phase 5).
- Runbook label names use the bare spanmetrics dimensions
(command, rpc_status, local, consensus_mode); fix stale docs.
- 05-configuration-reference: note tls_client_cert/key require use_tls=1.
- TelemetryConfig: reject mTLS cert paths when use_tls=0 so telemetry
is not silently sent in plaintext.

Operator-facing cleanup: strip the "(Phase 8)" suffix from the Log-Trace
Correlation section heading in the runbook.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Same operator-facing cleanup as the RPC/transaction/consensus headings: the
runbook documents the running system, not the development phase that added
each span. Strip the "(Phase 6)" suffixes from the Ledger and Peer span
reference headings.

The operator runbook is for people running OpenTelemetry against a node, not
a record of the internal development phases. Strip the "(Phase N)" suffixes
from the span-reference headings and replace the personal-name example
service.name value with a generic one.

Rename the 5 system-* dashboard files to bare domain names (uid ==
filename stem) and update all doc references. The system- prefix was
redundant now that titles no longer carry a recorder-pipeline suffix.

Make dashboard uids bare domain names (uid == filename stem) and update
doc references. Grafana links/bookmarks to the old uids will need
refreshing.

Add a Deployment Tiers section covering the four filtering dimensions
(node, service, network, environment), who owns each attribute, the
collector's upsert-vs-insert rule, per-tier collector values, and how the
tier labels reach metrics. This is the operator-facing home for the
deployment-tier feature.

The consensus.proposal.receive and consensus.validation.receive spans record
the trust flag under proposal_trusted / validation_trusted (shared with the
peer spans of the same message type), not a bare `trusted`. Update the span
reference table to match.
Bring phase-4 forward into phase 5 (docs & deployment). Phase 5 owns the
operator runbook (docs/telemetry-runbook.md).
Conflict resolution:
- 05-configuration-reference.md: took phase-4's code-block-free prose for the
config-parser section; the mTLS options (tls_client_cert/tls_client_key)
remain documented in the §5.1.2 options table.
Phase-5-owned naming fix:
- docs/telemetry-runbook.md: converted 20 dotted xrpl.<domain>. attribute keys
in the Span Reference tables to the underscore convention (tx_hash, peer_id,
ledger_seq, consensus_mode/round/round_id/ledger_id, tx_id). Span NAMES stay
dotted (rule 5). `trusted` left as-is — verified it matches the code constant
ConsensusSpanNames.h (the proposal_trusted/validation_trusted split is a
separate, not-yet-applied code change).
End-to-end reconciliation: every span-attribute token in the runbook (L5) now
matches an L1 *SpanNames.h constant. The xrpl_<domain>_<field> tokens are the
spanmetrics-derived Prometheus labels (documented mapping), not span attrs.

Head sampling is now fixed at 1.0 and not configurable. Drop the
sampling_ratio config row and redirect volume-reduction guidance to
collector-side tail sampling. trace_peer=0 stays as the high-volume opt-out.
