Subject JMX TotalReadLatencyMicros sanity check
Date Fri, 02 Sep 2011 18:30:07 GMT
I've graphed the rate of change of the TotalReadLatencyMicros counter over the last 12 hours,
and divided by 1,000,000 to get it in seconds.  I'm grabbing it every 10 seconds, so I divided
by another 10 to get per-second rates.

The result is that I have a CF doing 10 seconds of read *every second*.

Does that make sense?

If I divide it by the number of reads done, it matches up with the latency I'm seeing from
cfstats:  1.5ms/read.
