The line "hostgroup_name !hostgroup5" will completely
supercede anything previously specified for hostgroup_name in the
template.
If you want it to be processed as an addition to what was in your
template, you need to prefix the list with a "+". So in your service
definition, you need to put:
hostgroup_name +!hostgroup5
I've only ever used this syntax myself for specifying additional
contacts, but I guess the logic would be the same for hostgroups too.
Give it a try anyway and come back if it doesn't work.
I assume you're using Nagios 3. I don't think use of "+" in this way
was possible in version 2.
Cheers,
Jim
