-Re: Monitor: Adding graphs for each table and server

I went through the JMX mbeans using JConsole and it seems Accumulo supports
a good set of metrics through JMX.
I'm trying to figure out how to leverage openTSBD for Accumulo. From what
I've read so far, I haven't found an easy way to integrate with Accumulo so
that user can use its functionality very easily.
