vRA Agent Status Down - how to monitor..

Hi Folks,

is there a URL or something on the Agent server that we can query to find out the status of the vCenter agents? ( or where can we get that information). I know I can see it in the 'compute resource'  in the GUI, but I'm not going to be checking that 24x7 :-) , I'd like to have a vRO workflow that polls to see the status, and alert me if it's down, ( I'd even expand that to auto restart the service :-)) , but I can't seem to find where I could check for that status.

     Thanks in advance,

          John.
