-----------------------------------
[~jeagles], thanks for your contribution. The idea sounds interesting.
bq. As the Application Timeline Server is provided with built-in UI,
Do you mean that the timeline server does NOT have built-in UI? Hence if we
built a third-party web UI to demonstrate the metrics stored in the timeline
server, the current REST APIs set is not friendly for the web developers to do
the typical javascript-style queries. However, this could be solved by CORS and
JSONP. Is my understanding correct?

> As the Application Timeline Server is provided with built-in UI, it may make
> sense to enable JSONP or CORS Rest API capabilities to allow for remote UI to
> access the data directly via javascript without cross side server browser
> blocks coming into play.
> Example client may be like
> http://api.jquery.com/jQuery.getJSON/
> This can alleviate the need to create a local proxy cache.
