Subject [jira] [Created] (CASSANDRA-7897) NodeTool command to display OffHeap memory usage
Date Sun, 07 Sep 2014 22:04:28 GMT
Vijay created CASSANDRA-7897:

             Summary: NodeTool command to display OffHeap memory usage
                 Key: CASSANDRA-7897
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Vijay
            Assignee: Vijay
            Priority: Minor

Most of the highest memory consuming data structure in Cassandra is now off-heap. It will
be nice to display the memory used by BF's, Index Summaries, FS Buffers, Caches and Memtables
(when enabled)

This ticket is to track and display off heap memory allocation/used by running Cassandra process,
this will help users to further tune the memory used by these data structures per CF.
