Umesh Agashe 07c38e7165 HBASE-16549 Added new metrics for AMv2 procedures ... Following AMv2 procedures are modified to override onSubmit(), onFinish() hooks provided by HBASE-17888 to do metrics calculations when procedures are submitted and finshed: * AssignProcedure * UnassignProcedure * MergeTableRegionProcedure * SplitTableRegionProcedure * ServerCrashProcedure Following metrics is collected for each of the above procedure during lifetime of a process: * Total number of requests submitted for a type of procedure * Histogram of runtime in milliseconds for successfully completed procedures * Total number of failed procedures As we are moving away from Hadoop's metric2, hbase-metrics-api module is used for newly added metrics. Modified existing tests to verify count of procedures. Signed-off-by: Michael Stack <stack@apache.org>		2017-06-05 17:14:14 -07:00
