[jira] [Created] (HBASE-27948) Report memstore on-heap and off-heap size as jmx metrics in sub=Memory bean

Jing Yu created HBASE-27948:
-------------------------------

             Summary: Report memstore on-heap and off-heap size as jmx metrics in sub=Memory bean
                 Key: HBASE-27948
                 URL: https://issues.apache.org/jira/browse/HBASE-27948
             Project: HBase
          Issue Type: Improvement
            Reporter: Jing Yu
            Assignee: Jing Yu


Currently we only report "memStoreSize" jmx metric in sub=Memory bean. There are "Memstore On-Heap Size" and "Memsotre Off-Heap Size" in the RS UI. It would be useful to report them in JMX.

In addition, "memStoreSize" metric under sub=Memory is 0 for some reason (while that under sub=Server is not). Need to do some digging to see if it is a bug.
