Subject [jira] [Commented] (HBASE-15163) Add sampling code and metrics for get/scan/multi/mutate count separately
Date Mon, 25 Jan 2016 17:24:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15115585#comment-15115585
] 

Elliott Clark commented on HBASE-15163:
---------------------------------------

We already have those numbers with the histogram counting. There doesn't seem to be much use
in double counting.
Additionally this gets us back to the point were instantaneous rate is controlled by how long
inbetween metrics snapshots ( something that has been the cause of instability in metrics).
