Sounds a lot like what I use... I also use host-templates for example:

define host{
                use               solaris,dns,an-other-app
                address...
}

the solaris host-template applies standard checks like disk, cpu, SMF.
the solaris-10-global template applies checks such as zone-checks

the same can be applies to a windows / rhel template

our rhel and solaris templates actually "use" basic *nix templates too.

this was each hosts config is kept to a minimum. also keeping each host in
its own .cfg file helps eg .../customer1/server-name1.cfg then any host
specific checks (eg url checks) can be added to that one config file too.
