Server/host Inheritance

[Mark Gius]

You're going to want to read this: 
http://nagios.sourceforge.net/docs/3_0/objectinheritance.html, 
specifically "implied inheritance" about 3/4 of the way down.

Host and service inheritance is (mostly) separate.  There are some 
implied inheritance rules however.  For example, if a service doesn't 
define contact_groups anywhere, it will inherit contact_groups from its 
host.  If you override contact_groups in the service somewhere, it will 
use that instead.

You can add things using the "+" syntax (see additive inheritance), and 
you can kind of delete things with "!", but I've not played with that 
very much.
