This should be done to ensure that anyone who gets notified of a problem continues to get notified as the problem is escalated."

Thanks for your response.

If I change the interval to 300, than core and nopage get the
notification every 5 minutes after the 5th notification.  Then I page
won't get the first alert until 30 minutes after the host is down
(5 at 1min interval + 5 at 5min interval).  What I really want is nopage
and core to get notifications after service has been down for 5 minutes and
than 30 minutes after.  page to get notifications after service has been
down for 10 minutes and 30 minutes after.

I almost think the following will provide what I want but the
documentation section I posted in my original post makes me think this
is a bad idea.


define serviceescalation {
      hostgroup_name            location-v7apache
      service_description       v7apache-check
      first_notification        5
      last_notification         0
      notification_interval     1800
      contact_groups            nopage, core
}
define serviceescalation {
      hostgroup_name            location-v7apache
      service_description       v7apache-check
      first_notification        10
      last_notification         0
      notification_interval     1800
      contact_groups            page
}
