------------------------------------
Summary: List memstore direct memory/heap memory usage
Key: HBASE-20913
URL: https://issues.apache.org/jira/browse/HBASE-20913
Project: HBase
Issue Type: Improvement
Components: regionserver
Affects Versions: 2.0.0
Reporter: huaxiang sun
Assignee: huaxiang sun
With offheap write path support, mslab can be allocated at offheap memory.
Currently, RS Server Metrics, only show Memstore Size and it does not list the
DM usage for memstore. It will be good that memstore's offheap memory usage
along with the heap memory usage be shown at the webpage so we will know how
much DM is used for memstore.
