Inheritance and templating question

This is -exactly- how I'll be configuring our Nagios environment and 
it's gonna save me a boatload of work :) (>300 hosts, >3000 checks)

What you do is this:
1. Define a set of service checks you would like to assign to multiple 
hosts at once. For example: all Solaris boxen would need checks 
regarding cpu load, ram, swap, partitions root/var/tmp and metastat. At 
the top of the file, put all variables that are the same for each check 
into a template. Make sure that all your checks use this template with 
the "use" directive.
2. Create a service group called Solaris-checks.
3. Create a host group called Solaris-hosts.

Now comes the fun part:
4. Add all Solaris service checks to Solaris-checks.
5. Add all Solaris hosts to Solaris-hosts.
6. Add Solaris-hosts to each Solaris check as a subscriber by adding it 
to the -template- at the top of the file.

And presto! You now have a group of hosts subscribed to a group of 
services! The deal with the service groups is only for display purposes 
BTW, but I thought I'd throw it in there :)

Want to add additional services to all these hosts at once? Just define 
a service check and let it use the template. Want to add some Solaris 
boxen to the network? Just add them to the Solaris host group.

Cheers!


Thomas
