The two log-correlation checks have never executed in CI: the workflow
hardcoded --skip-loki, so validate_telemetry.py never constructed
log.trace_id_present or log.trace_id_cross_reference. A green Telemetry
Validation therefore carried no evidence that a log line reaches Loki with
trace context. Drop the flag so both checks run and can fail the job.
Correlation spans four independent legs and a failed check names none of
them, so run-full-validation.sh now prints a per-leg diagnostic after the
suite whenever the checks are enabled:
node per-node debug.log line count, the count matching the injected
trace_id/span_id shape, one sample line, and the severity mix,
so "no log at all", "log level too high" and "no active sampled
span" are distinguishable
mount the container-side listing of /var/log/xrpld, taken with the
collector's own mounts and uid. That image is built from
scratch and carries no shell, so the listing runs in a
throwaway container with --volumes-from, not via docker exec
collector the receiver's watched files, logs-pipeline warnings, and the
internal log-record counters, read from inside the container's
network namespace because that endpoint binds to the
container's own localhost and its port is not published
loki the exact query used, the label inventory, and entry counts for
the stream selector with and without the line filter, so "Loki
has nothing" and "Loki has lines but none carry a trace id" are
distinguishable
The diagnostics are non-fatal by construction: every leg runs in its own
subshell with errexit off, each docker and curl call is guarded, and the
coordinator always returns success. Verified with no containers and no Loki
reachable, with an emptied PATH, and with a leg forced to exit non-zero.
validate_telemetry.py gains a matching diagnostic beside the checks,
following _log_prometheus_metric_names: warnings only, never a check
result. Its stream selector and line filter move into module constants
that the shell diagnostic reads back, so the two cannot drift into
describing different queries.
No check was widened or auto-passed, and LOG_QUERY_WINDOW_SECONDS stays at
four hours; a wider window would let a check pass on a previous run's logs.
