rhevm-notification-service ?

I just noticed that after upgrading to rhevm-3.1 the rhevm-notification-service wasn't running anymore. Also it wasn't included in the list of services provided by "rhevm-notification-service". So I added it, and enabled it now.

chkconfig --add engine-notifierd

chkconfig engine-notifierd on

service engine-notifierd start

But I can't find any documentation for this service. Is it a secret service we're not supposed to be running, or just lacking documentation ?
