Subject Re: Accumulo Monitoring Page Improvements/redesign?

Along these lines curious where and how monitor stores its stats
currently.  I imagine some of it comes from  !METADATA but guessing not all
of it does (for example the time series).

If there was a clean way to access the stats there is no shortage of
powerful and pretty monitoring tools.
