----------------------------------------------

             Summary: RegionServer Metrics improvements
                 Key: HBASE-18374
                 URL: https://issues.apache.org/jira/browse/HBASE-18374
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 3.0.0
            Reporter: Abhishek Singh Chouhan
            Assignee: Abhishek Singh Chouhan
             Fix For: 3.0.0


At the RS level we have latency metrics for mutate/puts and deletes that are updated per batch
(ie. at the end of entire batchop if it contains put/delete update the respective metric)
in contrast with append/increment/get metrics that are updated per op. This is a bit ambiguous
since the delete and put metrics are updated for multi row mutations that happen to contain
a put/delete. We should rename the metric(eg. delete_batch)/add better description. Also we
should add metrics for single delete client operations that come through RSRpcServer.mutate
path. We should also add metrics for checkAndPut and checkAndDelete.
