> 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, 2.5.6, 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.
