mazhengxuan commented on HBASE-29640:
-------------------------------------
{{A fix is available in https://github.com/apache/hbase/pull/8563.}}
The patch adds an `oldestProcedureAge` gauge to the existing
`Master,sub=Procedure` metrics source. It reports the age in milliseconds of
the oldest unfinished master procedure and returns zero when no active
procedure is present.
The implementation includes coverage for finished procedures, an unavailable
procedure executor, clock adjustments, and metrics export.
