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.
The rename script rewrites "Ripple epoch" to "XRPL epoch", so the old
spelling in a tracked .md makes the check-rename job fail on a dirty tree.
The attribute key close_time_ripple_epoch_s is left alone: the script's
pattern needs a space, and that key is a cross-layer contract.
The plan doc offered `"attribute"` as the alternative to `"deterministic"`
for consensus_trace_strategy. The parser accepts `"random"`; "attribute"
described the correlation mechanism rather than the setting's value. Note
also that the alternative is experimental and not used.
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 emitted key is close_time_ripple_epoch_s, which names its unit and
epoch. Update the ledger attribute table to match.
ledger_index and ledger_tx_count in the same table belong to a separate
rename and are left as they are.
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.
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.
Conflict in OpenTelemetryPlan/03-implementation-strategy.md §3.9: both
branches independently fixed the same defect (stale hand-maintained line
counts) in different ways.
- 1b (0ff947454c) stripped the Lines Added / Lines Changed columns but kept
the §3.9.1 and §3.9.2 tables.
- 1a (3ad525a48a) removed both sections outright.
Resolved in favour of 1a's deletion. The tables were pre-implementation
estimates with no source of truth, so trimming the columns only defers the
next drift; the file/component lists duplicated §3.1's directory tree, which
1b already keeps current (DiscardFlag.h, FilteringSpanProcessor). Keeping the
upstream resolution also stops the same conflict recurring on 1c..10.
1b-specific content verified intact after the merge: §3.1 retains the
DiscardFlag.h entry, the FilteringSpanProcessor and discard() annotations,
and the TracingInstrumentation removal. No references to the deleted
sections remain in any plan doc.
The §3.9.1 "Files Modified Summary" and §3.9.2 "Detailed File Impact"
tables carried hand-maintained per-component line counts that had drifted
from the plan: the Lines Added column summed to 1,565 while the Total row
claimed ~1,670. Files (34) and Lines Changed (120) reconciled, so only the
Added total was stale — residue from expanding Core Telemetry 5 -> 11 files.
Rather than patch one cell, remove both tables. They were pre-implementation
estimates with no source of truth, so any figure in them drifts again on the
next phase. §3.1's directory tree remains the canonical list of the 11 new
telemetry files, and §3.9.3-3.9.7 (risk, architectural impact, backward
compatibility, rollback) carry the assessment without inventing line counts.
No references to the removed sections exist elsewhere in the plan docs.
- 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.

The network-type label is derived from [network_id] in TelemetryConfig.cpp;
unmapped/unset IDs fall through to "unknown", not "standalone". Align the
design-doc resource-attribute table with the code and cfg example.

State the rules so they stay consistent across code, collector, Tempo,
dashboards, and docs:
- Per-span-unique field -> bare name (the span name carries the domain).
- Same concept on more than one span -> ONE shared key, reused verbatim and
distinguished by span name, never tagged with the emitting workflow
(e.g. ledger_hash, full_validation, proposal_trusted/validation_trusted).
Defined once in the base SpanNames.h and re-exported by each domain header.
- Collision qualifier <domain>_<field> only to separate DIFFERENT concepts that
share a word, or the OTel-reserved status key (rpc_status, consensus_state).
- Dotted xrpl.<...> is reserved for resource attributes (xrpl.network.*).
Updates CONTRIBUTING.md (permanent home) and OpenTelemetryPlan §2.3.3.
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.

Bring the span attribute naming convention (phase 1a) into phase 1b.
Conflict resolution kept phase-1b's SpanGuard-based workflow and applied
the underscore naming convention to all non-code-sample text:
- Converted prose, tables, Mermaid labels, and TraceQL/PromQL query
references across the plan docs to the underscore form.
- Converted the two @code attribute-key examples in Telemetry.h
(command, tx_type).
- Left the code-sample files (04-code-samples.md, POC_taskList.md) and
03-implementation-strategy.md code blocks at the phase-1b version; the
code-sample docs are slated for removal on phase-1a.

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.

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.
Move Telemetry.h (associated header) to first include position in
Telemetry.cpp per the project's include-order convention. Trim
trailing whitespace from POC_taskList.md markdown table columns.

Redesign SpanGuard with pimpl idiom to hide all OpenTelemetry types
from public headers. Add global Telemetry accessor so SpanGuard factory

Plan documents referenced Application.h and app_ for getTelemetry()
but the codebase now uses ServiceRegistry as the interface. Updated:
- 05-configuration-reference.md: getTelemetry() on ServiceRegistry,
deferred serviceInstanceId pattern in ApplicationImp
- POC_taskList.md Task 4: target ServiceRegistry.h not Application.h,
correct config file path and constructor pattern
- 04-code-samples.md: fix overlay() -> getOverlay(), rewrite JobQueue
sample to reflect actual architecture (no app_ member)
- 03-implementation-strategy.md: fix file impact table path
