I finally got some time to do some house cleaning. One of my
nagging low-hanging fruit jobs was to stop using jconsole as my
monitor. I created a ganglia script to graph what is above. The
image illustrated above I am showing all the Cassandra servers
and their total row read stages completed in the last hour as a
