Whenever we get a new device I can just add it to the right host group and it gets all of its service checks by being a member of that hostgroup.

The only thing I’ve been able to think of is using an external command at nagios start up that checks all of the services on the master server and works out which ones belong to remote sites and then disables active checks on each one, but this seems like a messy way.

The local check applys to its function group AND all devices at the head office while the remote check applies to its function group AND all remote hosts, however at present I think this functionality is unavailable.

You want to use templating so that the master is set to "active checks enabled no" while the slave is set to "active checks enabled yes".

In Opsview (http://opsview.com), our db based configuration database knows if a host is monitored on the master or on a remote slave. We generate configurations for a host (and services) appropriately. We've also done loads of work so you can manage it from the central master and it will distribute downtimes/acknowledgements/disables to slave systems as well.
