stack updated HBASE-12455:
--------------------------
Attachment: 12455.v2.txt
with_descriptions.json
raw.json
Thanks for the prompt [~eclark]
This should do. It prints out descriptions if they are non-null and if they
are not the same as the attribute name.
I've uploaded what a page looks like now and then what happens when you ad
'?description=true'. If I get a +1, I'll commit and update refguide at same
time. Will file follow-on issue to go over the metrics descriptions to add
info where descriptions are unclear and to add some where they are missing.
> Add 'description' to bean and attribute output when you do
> /jmx?description=true

> 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.
