Peter Somogyi reopened HBASE-27892: ----------------------------------- This commit causes compilation failure on branch-2.4. Reopening for the revert. > Report memstore on-heap and off-heap size as jmx metrics > -------------------------------------------------------- > > Key: HBASE-27892 > URL: https://issues.apache.org/jira/browse/HBASE-27892 > Project: HBase > Issue Type: Improvement > Components: metrics > Reporter: Bryan Beaudreault > Assignee: Jing Yu > Priority: Major > Fix For: 2.6.0, 2.4.18, 2.5.6, 3.0.0-beta-1 > > > Currently we only report "memStoreSize" metric in sub=RegionServer bean. I've > noticed a big discrepancy between this metric and the RS UI's "Memstore > On-Heap Size". It seems like "memStoreSize" is the overall data size, while > the on-heap size is coming from our heap estimation which includes POJO heap > overhead, etc. > I have a regionserver with only 750mb of "memStoreSize", but the on-heap size > is over 1gb. This is non-trivial for estimating overall heap size necessary > for a regionserver. Since we have the data, let's report it. -- This message was sent by Atlassian Jira (v8.20.10#820010)
