stack created HBASE-12455:
-----------------------------

             Summary: Add 'description' to bean and attribute output when you do /jmx?description=true
                 Key: HBASE-12455
                 URL: https://issues.apache.org/jira/browse/HBASE-12455
             Project: HBase
          Issue Type: Improvement
          Components: metrics
            Reporter: stack


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.
