Thanks Terry, interesting idea, and I got most of the way through setting up
a test configuration before I realised that it's not quite the right
solution for me. I'd like to be able to specify particular services on
particular hosts, and to use service escalations to do that, I'd have to set
up a service escalation for each 'critical' service for each host. If I
could specify a servicegroup instead of a hostgroup in a service escalation
definition, it would be perfect, as I could set up a 'critical' servicegroup
that included all the 'critical' services and set up a single service
escalation :)

Regards,
Guy.
