-----------------------------
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.
