---------------------------------------------------------------------
For cfhistograms how should the readLatency / writeLatency be accessed. The
LatencyMetrics object isn't accessible over JMX. jconsole shows it as a Timer.
Maybe we can switch to having percentiles being shown by cfhistograms (read
write latency for 50/75...99.9% and display the averages aswell)

> Project: Cassandra
> Issue Type: Task
> Reporter: Yuki Morishita

> Priority: Minor
> Fix For: 2.1

>
> Since C* 1.2, metrics are moved from *MBeans to own o.a.c.metrics package and
> are exposed through metrics-core library.
> But nodetool is still using deprecated MBean metrics, so it is time to
> migrate to new API.
