I'm of the understanding that shinken supports service/hostescalation, in addition to its own "escalation", by name, referenced directly by a host/service or its template.

I want to add an escalation by servicegroup, using serviceescalation, but it's not working.
define escalation {
servicegroup_name chris
contacts +chris-xmpp
first_notification 1
last_notification 0
notification_interval 0
}

I see the services I expect a members of servicegroup:chris, yet the contact is never notified.

I see someone reported a similar problem ~5 years ago; was there any resolution or is there any outstanding problem ?
