Thanks, Charles.

If only I had a time machine.  About 10 seconds after I hit the send button
I realized I had been using host_name instead of hostgroup_name.

Thanks also to everyone else who is currently responding with "Hey idiot!!

you don't want to use the host_name parameter in the service definition, you
want to use the hostgroup_name parameter.

Hostgroups specified under the hostgroup_name will get expanded and the
hosts specified in host_name will be added to the list so you can add
some one-off hosts to these services if you want.

hope that helps
