requireReadableFile proved a path readable with getFileContents, which
loads the whole file into a std::string and then drops it. One of the
three paths it checks is tls_client_key, so a private key was loaded to
answer a question that does not need its contents. It now stats the
path, rejects anything that is not a regular file, and opens it without
reading. The message shape is unchanged:
"[telemetry] <key> cannot be read: <path> - <reason>".
A path naming a directory used to escape as an ios failure from the
stream buffer, naming neither the config key nor the path. It is now
rejected as "not a regular file" with both named. The new test covers
that case; it fails against the old implementation and against a copy
with the file-type branch removed.
The runbook's quick start and disable sections both told the reader to
run "cmake --preset default". No presets file is tracked, and the only
preset Conan generates is conan-release, so each of those steps failed
on its first command. Replaced with the flow BUILD.md documents, and
noted that telemetry is the current default while still passing the
flags.
The OTLP/HTTP exporter selects TLS from the endpoint URL scheme alone
(HttpSslOptions in the pinned SDK matches "https:" exactly), so a client
certificate handed to it alongside an http:// traces_endpoint is loaded and
never presented. The parser checked the cert/key pairing, use_tls and file
readability, but never the scheme, and the default traces_endpoint is plain
HTTP. makeTelemetrySetup() now requires traces_endpoint to start with
"https://" whenever tls_client_cert is set, including when the key is left
at its default.
Nothing asserted the client options reaching the exporter, so a swapped
certificate and key would have passed every test. Move the options mapping
into makeTraceExporterOptions() and assert it at that boundary with
distinct certificate and key paths, plus a one-way-TLS control and a
use_tls=0 control. One case runs the whole path from a [telemetry] section.
Runbook and example-config fixes:
- tx.included is emitted per transaction of the agreed consensus set,
before buildLCL() applies anything, so it is a superset of the accepted
ledger rather than proof of inclusion.
- the dispute.resolve query used the descendant operator, but the event is
on the consensus.update_positions span itself, so it matched nothing.
- the exhausted-retries query asked for txq_status="retried" with
retries_remaining=0, which cannot occur: the attribute is stamped before
the attempt and the retried branch only runs while retries are left.
Exhaustion is txq_status="failed" with a zero count.
- consensus_round_id is an int64, so the two queries comparing it to a
quoted string matched nothing.
- note that consensus_trace_strategy=random is experimental and not used.
- note that a trailing "| attr = value" is rejected by current Tempo;
attribute filters belong inside the braces.
The consensus.accept.apply row listed close_time, parent_close_time and
close_time_self. The emitted keys carry the unit and epoch suffix, so
update the row to match.
The rename arrived from phase-1b by merge; the runbook still told
operators to set `endpoint`, which the parser no longer reads. Updates
the Quick Start ini block and the Configuration Reference row.
No metrics_endpoint row is added: this branch exports no metrics, so
documenting the key here would describe something the code ignores.
close_time_avalanche_state is new; the row also did not say that the other
three are rewritten on every convergence iteration, so a reader could not tell
that the exported value is the last one rather than a series.
This row is byte-identical on phases 5 through 10, so it is edited here and
merges forward. The consensus.phase.open row is empty until phase 9 and is
updated there instead.
Bring the three documentation surfaces in line with the new parse-time check:
- The @throws clause on makeTelemetrySetup now names the third failure
condition and records that an empty path is skipped.
- cfg/xrpld-example.cfg states, under all three TLS keys, that with enabled=1
and use_tls=1 a path that does not exist or cannot be read stops startup. The
tls_ca_cert wording still says that empty selects the system CA store, since
only a path that is set is checked.
- The runbook troubleshooting entry gains a third bullet for the "cannot be
read" message, whose remedy is the path or its permissions rather than the
certificate and key pairing.
Documentation only; no behaviour change.
makeTelemetrySetup() rejects a contradictory [telemetry] mutual-TLS
setup by throwing, but it is called from ApplicationImp's
member-initializer list. A try/catch in the constructor body cannot
reach a throw from there, and nothing further up the stack caught it
either, so a config mistake reached std::terminate: the default handler
printed a terminate dump and raised SIGABRT, leaving a core file
instead of a startup error.
Catch std::exception around makeApplication() in run(), report the
reason on stderr and return -1, so the failure is a clean non-zero exit
with a message an operator can act on. Only the construction is
wrapped. setup() starts subsystems whose shutdown order is delicate and
is left outside deliberately, because unwinding a half-started
Application would skip the normal stop sequence.
Gate both validation guards on enabled. A node with telemetry switched
off previously refused to start over certificate paths that nothing
would read.
Document both throws on makeTelemetrySetup(), state in
cfg/xrpld-example.cfg and the configuration reference that a partial
mutual-TLS setup is fatal and that the checks apply only when
enabled=1, and add a runbook troubleshooting entry keyed on the two
error messages.
Tests cover both guards with the message asserted so the two are told
apart, both enabled=0 paths, and the default plaintext configuration.
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.

- 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.

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.

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.

Reflect the new on-by-default behavior in the config defaults table. The
volume-reduction guidance (High memory usage, Production mainnet tuning)
intentionally keeps trace_peer=0 as an opt-out recommendation for
high-traffic deployments.

Adds comprehensive "Insights and Sample Queries" section showing operators
what questions they can answer with the newly-added span attributes:
- Transaction workflow analysis (filter by tx_type, fee, ter_result)
- TxQ health (txq_status, ledger_changed)
- RPC debugging (is_batch, request_payload_size, load_type)
- PathFinding performance (dest_currency, num_source_assets)
- Consensus health (consensus_state, is_bow_out, disputes_count)
- Cross-subsystem correlation examples
Also updates all span reference tables with the new attributes.

- RPC Spans table: `rpc.request` was documented but the code actually emits
`rpc.http_request`. Listed the actual emitted names
(`rpc.http_request`, `rpc.ws_upgrade`, `rpc.ws_message`, `rpc.process`)
and their parent/child relationship.
- Drop `:<line>` suffixes from Source File columns in both RPC and
Transaction span tables. Line numbers drift with every refactor; the
filename is enough for operators to grep.
- Summary table: replace the never-emitted `rpc.request` row with the real
entry points so `span_name=` filters in PromQL / TraceQL match.
Update 31 attribute references in telemetry-runbook.md to match the
simplified naming: drop xrpl.<domain>. prefix on per-span attrs, use
domain-qualified names for collisions (rpc_status, consensus_state,
etc.), and unify cross-domain refs (xrpl.ledger.seq, xrpl.tx.hash).

Document the propagation infrastructure: send-side injection in
NetworkOPs/RCLConsensus, receive-side extraction in PeerImp via
PropagationHelpers.h and ConsensusReceiveTracing.h. Update
consensus receive span descriptions to reflect parent extraction.
