Caroline Zhou commented on HBASE-25469:
---------------------------------------
[~apurtell] [~stack] [~tianjingyun] [~bharathv] [~vjasani] Please take a look.
Added a few fields to the rit.jsp page as well as created a new servlet to
serve individual RIT information as json (RIT info in one place, can be parsed
for metrics). A couple of things to consider/I would like your feedback on:
* Any other fields we should add to the json output? (Aggregates like
ritCount, ritCountOverThreshold, etc. can be found in AssignmentManager metrics
so I didn't include those here.)
* Should we include the ability for the json to display only RIT over
threshold/RITs grouped by state or server name?
I would also like to backport this to branch-1, after master PR is approved.
Thanks.

> In HBase 2.1+, there is a RIT JSP page that was added as part of HBASE-21410.
> There are some additional RIT details that would be helpful to have in one
> place:
> * RIT Start Time
> * RIT Duration (ms)
> * Server
> * Procedure Type
> This info can be added to the table under the {{/rit.jsp}} page, and we can
> also add a button on that page to view info as JSON, for easy parsing into
> metrics, etc. This JSON dump can be served as a servlet.
> We may also consider different ways of grouping the JSON results, such as by
> state or server name.
