> 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.
