laneser kuo closed CASSANDRA-4653.
----------------------------------
Thanks reply, after taking more time to read code,
the latency data comes from addNano , which is 10^-9 seconds,
then histograms store data in micro seconds, which is 10^-6 seconds,
and cfstats shows milliseconds, which is 10^-3 seconds.
> nodetool cfstats Lantecy unit is wrong , it should be sec (seconds) instead
> of ms (micro seconds)

> I was mislead by the nodetool cfstats Read Latency and Write Latency data.
> Until I read the source code, it should display sec instead of ms.
> for example:
> outs.println("\t\tRead Latency: " + String.format("%01.3f",
> cfstore.getRecentReadLatencyMicros() / 1000) + " ms.");
