Sammy Yu commented on CASSANDRA-406:
------------------------------------

For each CF, in the patch nodeprobe counts the number of sstables already by 
count the number of keys returned in CFS.getSSTablesInfo.  We could add a 
specific method that just returns count as it may make it easier for JMX 
clients.

Do we want to return the total size used in the data directory for each CF or 
does do we want it globally for StorageService level?  I was thinking of adding 
one at the StorageService level and it would just return the free space for 
each data directory.
