Sylvain Lebresne resolved CASSANDRA-7071.
-----------------------------------------
    Resolution: Won't Fix

Doesn't sounds like this is gonna go anywhere unless someone has a concrete suggestion on
what to expose and more importantly, how to expose it. So closing but feel free to re-open
if you have such concrete suggestion.

> It's currently very difficult to understand how the buffer cache is being used by Cassandra.
Unlike the key and row cache, for which there are hit rate metrics pulled by the datastax
agent and visible in opscenter, there are no such metrics around the buffer cache. This would
be immensely useful in a production environment.
