The pinned collector warns on every start that "otlp" is a deprecated alias
for "otlp_grpc". Rename the trace exporter to otlp_grpc/tempo.
Only the exporter is affected. The otlp RECEIVER keeps its name: it serves
both gRPC and HTTP under one component and is not deprecated, verified by
renaming the exporter alone and seeing the warning stop.
This belongs on this branch because it introduces the exporter, and it is the
last of four deprecated aliases in the collector config; the other three are
owned by later branches in the chain.
retries_remaining is stamped on the txq.accept_tx span before the
transaction is applied and before the retry counter is decremented, so a
span with txq_status="retried" always shows a non-zero count and exhaustion
shows up as txq_status="failed" with zero. The attribute comment said only
"retries left before discard", which reads as a post-decrement value and
led to a runbook query that could never match.
Also rename the drifted consensus_trace_strategy value in the plan docs
from "attribute" to "random", the spelling the parser accepts, and note that
it is experimental and not used.
One conflict, in SpanGuard.h: this branch added struct TraceBytes and upstream
added enum SpanRole at the same position after TraceCategory. Unrelated
declarations, so both are kept.
Review feedback on the plan documents. Four kinds of error:
- Symbols that do not exist: ConsensusProposal::prevLedger_ (it is
previousLedger_), RCLConsensusAdaptor (it is RCLConsensus::Adaptor, and
startRound() is on RCLConsensus itself), and RPCHandler::doCommand (a free
function, xrpl::rpc::doCommand).
- Attribute keys: the tables used ledger_index, which no telemetry code emits.
Same concept as ledger_seq but a different referent, so the code disambiguates
by prefix: current_ledger_seq for the open ledger a transaction targeted,
ledger_seq for a closed or validated one. A note now states which is which.
- TraceQL that does not parse: span-field predicates need braces, status.code
is not an intrinsic (status = error), and avg(duration) does not take a by
clause (avg_over_time does). All five re-tested against Tempo.
- The StatsD comparison omitted the Histogram instrument, which aggregates at
the point of measure, and the when-to-use table had no row for a metric that
spans cannot afford to carry.
The commented [telemetry] block in cfg/xrpld-example.cfg documented 8 of the 14
keys the parser accepts. Add the six that were missing - service_instance_id,
use_tls, tls_ca_cert, batch_size, batch_delay_ms and max_queue_size - each with
the unit and default read from the parser, and rename the documented endpoint
key to traces_endpoint so it matches what makeTelemetrySetup reads.
use_tls is documented for what it does rather than what its name suggests: it
gates whether tls_ca_cert reaches the exporter as a CA bundle, while the scheme
of traces_endpoint is what selects TLS. The path is not opened during parsing,
so an unreadable file surfaces as an export failure at runtime.
05-configuration-reference.md named three symbols that do not exist:
setup_Telemetry, make_Telemetry and Section::value_or. Correct them to
makeTelemetrySetup, makeTelemetry and Section::valueOr.
Conflict in OpenTelemetryPlan/05-configuration-reference.md: phase-3 had
widened the options table and added the tx_trace_strategy and
consensus_trace_strategy rows, while the incoming side renamed the
endpoint option.
Composed both — phase-3's wider layout and its two extra rows are kept,
with the endpoint row renamed to traces_endpoint.
The [telemetry] option table documents the config key operators copy.
The key is now traces_endpoint, named for the one OTLP signal it
carries, so the old row pointed at a key the parser no longer reads.
Two prose mentions of "endpoint" further down describe the concept
rather than naming the key, and are left alone.
The configuration reference typed the five trace_* switches as bool with
default true. An xrpld config section carries integers, and these keys are
read with an integer cast, so a literal "true" fails to convert rather
than enabling the switch.
Type them as 0 or 1 with default 1, matching the other integer-valued
keys in the same table.
Telemetry must read state, never change it. Two defects here did change it,
plus three smaller correctness and privacy fixes.
doPathFind and doRipplePathFind read source_account / destination_account off
context.params to hash them into span attributes. context.params is non-const,
so those reads selected json::Value's non-const operator[], which inserts a
null for a missing key. The same object is later validated by
PathRequest::parseJson, whose first checks are isMember(source_account) and
isMember(destination_account) — so a request that omitted either field looked
present and the client received Malformed instead of Missing. Reads now go
through std::as_const, whose overload returns kNull without inserting.
PathRequest::doUpdate emitted pathfind_dest_currency as
to_string(saDstAmount_.asset()). For a non-XRP asset that renders as
"<issuer>/<currency>" with the issuer as a plaintext Base58 address, so a
plain account address reached the span pipeline even though every other
account here is hashed first. The issuer is now redacted and the currency
kept; an MPT asset renders as its issuance ID and carries no address.
PathRequestManager::updateAll created pathfind.update_all with an unscoped
SpanGuard. An unscoped guard takes the ambient span as its own parent but does
not itself become the ambient parent, so the pathfind.compute spans that
doUpdate creates never nested under it, contradicting the documented hierarchy.
It is now a scoped guard, held in std::optional because ScopedSpanGuard is
deliberately non-movable and so cannot be produced by a ternary. The skip when
there are no active subscriptions is preserved. updateAll is dispatched via
addJob and doUpdate runs synchronously, so the guard is constructed and
destroyed under the same context store, as ScopedSpanGuard requires.
The WebSocket entry point emitted the client-supplied command string directly.
That value becomes a Prometheus label, so arbitrary request input could drive
unbounded label cardinality. It is now resolved against the handler registry,
collapsing anything unrecognized to "unknown", matching what the HTTP path
already does.
Also: the pathfind.discover comment claimed future child spans could be
parented off it, which its unscoped guard cannot do — corrected to say what
would be required instead. Config-reference and task-list docs named the
parser setupTelemetry(); the API is makeTelemetrySetup().
- 05-configuration-reference: service_name now applies to metrics as well
as traces (service.name resource attribute).
- 07-observability-backends: document that collector enrichment includes
deployment-tier tagging (deployment.environment + fallback
xrpl.network.type) for filtering one Grafana stack by tier.

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 naming convention, code-sample cleanup, and CI naming check into
phase 2 (RPC tracing). Phase 2 introduces PathFindSpanNames.h.
Conflict resolution:
- 04-code-samples.md, POC_taskList.md: deletion wins.
- 02-design-decisions.md: took the convention-applied tables, but kept phase-2's
accurate PathFinding summary row (pathfind_fast/search_level/num_paths/...,
matching the implemented PathFindSpanNames.h).
- 05/08: took the code-block-free prose; kept phase-2's Phase2-5_taskList.md
index rows (dropping only the deleted POC row). Fixed stale setup_Telemetry/
make_Telemetry doc references to the code-correct setupTelemetry/makeTelemetry.
- Telemetry.h auto-merged to the constant-based @code examples.
check_otel_naming.py change: exempt test files from Rule F (tests pass
arbitrary literal keys to exercise the API). The check passes clean on the
merged tree (24 keys across 4 *SpanNames.h headers, including PathFind).

Establish the single, authoritative naming convention for OpenTelemetry
span attribute keys so the code, collector, Tempo, dashboards, and docs
stay in sync.
- CONTRIBUTING.md: new "Telemetry span attribute naming" section under
the Style guide as the permanent, canonical home for the rules.
- OpenTelemetryPlan/02-design-decisions.md: new section 2.3.3 stating the
decided convention as design, and section 2.4 attribute schema realigned
to the underscore form (exact key spelling defers to the *SpanNames.h
constants).
- Sweep the remaining plan docs: convert dotted xrpl.<domain>.<field> span
attribute keys to the underscore form; leave span names and the
OTel-standard service.*/http.* and xrpl.network.* resource keys dotted.

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.

Flip trace_peer default false->true across the Phase-1a plan docs and
correct the rationale: peer spans record only peer_id (numeric local
connection id) plus trust/ledger metadata, never IP addresses or public
keys, so the 'includes addresses' caveat was inaccurate. The high-volume
note is retained.

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.

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.
Update OpenTelemetryPlan docs and Telemetry.h doc example to reflect
the renamed per-span attributes: xrpl.rpc.command -> command,
xrpl.rpc.status -> rpc_status, xrpl.grpc.method -> method, etc.

Add trace_id = txHash[0:16] strategy so all nodes handling the same
transaction independently produce spans under the same trace_id,
combined with protobuf span_id propagation for parent-child ordering.
