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

                 Key: HBASE-5786
                 URL: https://issues.apache.org/jira/browse/HBASE-5786
             Project: HBase
          Issue Type: New Feature
          Components: metrics, regionserver
    Affects Versions: 0.92.2, 0.94.0, 0.96.0
            Reporter: Jonathan Hsieh
            Assignee: Shaneal Manek


Average time for region operations doesn't really tell a useful story when that help diagnose
anomalous conditions.

It would be extremely useful to add histogramming metrics similar to HBASE-5533 for region
operations like flush, compaction and splitting.  The probably should be forward biased at
a much coarser granularity however (maybe decay every day?)
