[jira] [Created] (HBASE-20603) Histogram metrics should reset min and max in snapshotAndReset

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

             Summary: Histogram metrics should reset min and max in snapshotAndReset
                 Key: HBASE-20603
                 URL: https://issues.apache.org/jira/browse/HBASE-20603
             Project: HBase
          Issue Type: Bug
          Components: metrics
            Reporter: Andrew Purtell
            Assignee: Andrew Purtell


It's weird that the bins are reset at every monitoring interval but min and max are tracked over the lifetime of the process. Makes it impossible to set alarms on max value as they'll never shut off unless the process is restarted. Histogram metrics should reset min and max in snapshotAndReset.

For discussion.
