Custom Service Quick Links

[Giovanni Paolo Gibilisco]

Hi,
I've installed the standalone version of Spark via Ambari. I'm able to
start and stop it but I would also like to have the "Quick Links" element
in the service page on ambari with a link to the Spark Master UI.
Where can I define the information related to the quick links section?
I would also like to know a bit more about the service status monitoring,
where can i find some information on this topic?
Best,
Giovanni
