[jira] [Created] (CASSANDRA-7071) Buffer cache metrics in OpsCenter

Jay Patel created CASSANDRA-7071:
------------------------------------

             Summary: 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: 3.0


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.
