             Summary: Fix memStoreSize metric for a table and add heap and 
off-heap size metrics
                 Key: HBASE-28985
                 URL: https://issues.apache.org/jira/browse/HBASE-28985
             Project: HBase
          Issue Type: Bug
          Components: metrics
            Reporter: Junegunn Choi


The "memStoreSize" metric for a table is incorrect as it reports the sum of the 
data size, the heap size, and the off-heap size, while "memStoreSize" metric 
for a region or a region server is just the data size.

https://github.com/apache/hbase/blob/e082405d8e7fa5c9b89e7af3153f022731168ecb/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/MetricsTableWrapperAggregateImpl.java#L79-L80

We should fix it to report only the data size for consistency and add 
additional metrics, similarly to HBASE-27892, not to lose the extra information 
for understanding the flush behavior.

* {{memStoreHeapSize}}
* {{memStoreOffHeapSize}}
