Brandon Williams updated CASSANDRA-6539:
----------------------------------------

    Attachment: 6539-2.0.txt
                6539-1.2.txt

Initial patches against 1.2 and 2.0.  I couldn't find a way to customize most of the 'fancy' metrics classes like Histogram and Counter, so I made them gauges and either summed or averaged as appropriate.  I'm not sure what to do about the things using LatencyMetrics, so I bailed on that for now.

> It would be useful to be able to see aggregated metrics (write/read count/latency) at a keyspace level as well as at the individual column family level.
