Subject [jira] [Updated] (HBASE-18469) Correct RegionServer metric of totalRequestCount
Date Fri, 11 Aug 2017 06:11:00 GMT

     [ https://issues.apache.org/jira/browse/HBASE-18469?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yu Li updated HBASE-18469:
--------------------------
    Hadoop Flags: Reviewed
    Release Note: In HBASE-18469 we introduced a new RegionServer metrics in name of "totalRowActionRequestCount"
which counts in all row actions and equals to the sum of "readRequestCount" and "writeRequestCount".
Meantime, we have changed "totalRequestCount" to count only once for multi request, while
previously we will count in action number of the request. As a result, existing monitoring
system on totalRequestCount will still work but see a smaller value, and we strongly recommend
to change to use the new metrics to monitor server load.

Adding release note
