Dmitry Werner updated IGNITE-29047:
-----------------------------------
Labels: from-log-to-metric (was: metrics)
> Add ignored failure count metric to FailureProcessor
> ----------------------------------------------------
>
> Key: IGNITE-29047
> URL: https://issues.apache.org/jira/browse/IGNITE-29047
> Project: Ignite
> Issue Type: Task
> Reporter: Dmitry Werner
> Assignee: Dmitry Werner
> Priority: Major
> Labels: from-log-to-metric
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Currently, the event "Possible failure suppressed accordingly to a configured
> handler" is only reported via the log by FailureProcessor. There is no way to
> track how often such failures occur without parsing (grepping) the log.
> We need to expose this as a metric so the count of suppressed (ignored)
> failures can be monitored through the metrics subsystem (e.g. JMX, system
> views, exporters) instead of relying on log parsing.
> *Proposed change*
> - Register a new metric group failure (register name: failure) in
> FailureProcessor.
> - Add a counter metric IgnoredFailuresCount that is incremented every time a
> failure is suppressed (ignored) by the configured failure handler — i.e.
> exactly where IGNORED_FAILURE_LOG_MSG is printed.
> - Keep the existing log message unchanged.
> - Document the new metric in docs/_docs/monitoring-metrics/new-metrics.adoc.
> *Acceptance criteria*
> - The metric is exposed and readable through the standard metrics subsystem.
> - The metric increases by 1 for each suppressed failure and is not affected
> by failures processed normally (not ignored).
> - A unit test covers the above behavior.
