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.
> Buffer cache metrics in OpsCenter
> ---------------------------------
>
> Key: CASSANDRA-7071
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7071
> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Reporter: Jay Patel
> Fix For: 3.x
>
>
> 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.
