> Its hard figuring what our metrics mean. Each attribute and bean actually has a description
but its hard to get at. In mission control, etc., you have to click on each attribute to see
the description. Its painful.  Because the description is rarely read, they are not as info-full
as they could be.
> If you do /jmx in the UI, you get a dump of all beans associated with the server but
its just the attribute/bean name + value. The description is there but its not displayed.
We should give option to display descriptions. It would be good for those exploring what metrics
are available.  We actually point folks at jvisualvm in the refguide to figure what metrics
are available.  Would be useful if we could point them at something that was easier to navigate.
