I have another host template called 'oncall-host' that I'm using to represent people on call 24x7. If a host is critical enough that the on-call people should be alerted if it goes down, I want to be able to add the 'oncall-host' host template as a template for the critical host, have the 'unix-host' host template as another template for the host, and have nagios alert both the people on call and the Unix Team admins if the host goes down. The on-call people should be alerted by SMS and email every 5 minutes, but the Unix Team admins are should only be alerted by email every 10 minutes.

What's happening is that the on-call people are being alerted by SMS and email every 10 minutes (which is as it should be), but the Unix Team admins aren't being alerted at all. If I remove the 'oncall-host' template from the host definition, the Unix Team admins are alerted by email as they should be.

Adding a "+" before "oncall-primary" in oncall-host to specify that it
should be added to the list of contacts, rather than to replace it
completely, should give you what you want.
