You mean pacemaker alerts right?

Nope but actually shouldn't be that hard to implement. What exactly 
would you like to see there?

Not directly (again, shouldn't be that hard to implement). But pacemaker 
alerts should be triggered when service changes state because of ticket 
grant/reject, isn't it?

I don't think "boothd arbitrator is unreachable" alert is really doable. 
Ticket moved from x to y would be probably two alerts - 1. ticket 
rejected on X and 2. granted on Y.

Would you mind to elaborate a bit more on events you would like to see 
and potentially open issue for upstream project (or, if you have a RH 
subscription try to contact GSS, so I get more time to work on this issue).
