The monitor is awesome. It should die.
I'm going to move other monitor tickets under this one (if I can), and create some requirement tickets.
We would be better off putting our weight behind an existing monitoring program which can scale, if one exists.
Hopefully we can combine tracing efforts and have a nicer distributed trace-based tool, too.
Currently all of Accumulo monitoring information is exposed via JMX; a nice balance could be found leveraging the existing monitoring capabilities with JMXTrans (or equivalent) and applying a new GUI.
Familiarity with Java and JMX would be ideal.
