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.
The table of contents in this file indexes third- and fourth-level headings,
so a new subsection that is absent from it is a gap rather than a style
choice.
Compiled out, compiled in and tracing, compiled in with no active span, and
compiled in but disabled by config all have to produce the right wire bytes,
and only two of them are obvious. Tabulate them, and record why the predicate
reads the context directly instead of calling GetSpan(), which allocates a
DefaultSpan in the no-span case.
mutable_ on a protobuf optional submessage allocates it and sets its has-bit
at the call site, before the helper can decide there is nothing to write. A
caller that dereferences it ships an empty TraceContext whenever nothing is
recorded, and its peers each take a branch to extract nothing.
Document the rule with the right and wrong forms side by side.
The conditional-compilation section promised zero overhead when telemetry is
not wanted. The span disappears, but the arguments passed to it do not: the
compiled-out guards are ordinary inline functions, so a to_string() or a hash
in an argument list still runs and its result is then discarded.
State that, show the guard that does remove the work, and name the opposite
case -- the metric macros, which discard their arguments and need no guard.
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.

detached() strips the thread-local OTel Scope so a guard can be safely
moved to and destroyed on another thread; it pops the Scope on the origin
thread and moves the span into a scope-less guard. rootSpan() starts a span
as a fresh trace root (kIsRootSpanKey) so inbound entry points never inherit
an ambient span left active on the thread.
Impl now holds an optional<Scope> (nullopt for detached guards). Updated the
SpanGuard class docs and docs/build/telemetry.md with the cross-thread rules.
The unit test lands on phase2 where the telemetry test module exists.

- 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.
