Elliott Clark commented on HBASE-12455:
---------------------------------------

Why remove the hadoop JVMMetrics ? That provided: name: "Hadoop:service=HBase,name=JvmMetrics"
Granted you can find all of those things in other places so I could be convinced that removing it is the right thing to do.

> 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.
