Hi Eric, 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.
