Nagios 3.3.1 - Tips and tricks I've picked up...

New Hosts can take ages to setup.... but I've picked up a new way of doing things from @standaloneSA what a fabulous way of doing things.

SETTING UP SERVICES TO CHECK HOSTGROUPS INSTEAD OF INDIVIDUAL HOSTS

So when specifying your new hosts...instead of doing it this way --> where you specify each host_name, setup your services to check "hostgroups" instead of individual hosts :o) much easier to setup and cleaner to look at.

Extract from windows.cfg 

define service{
        use                                   generic-service
        host_name                      AISCTSRV02,AISCTSRV03,AISCTSRV01
        service_description        Uptime
        check_command            check_nt!UPTIME
        }

The much better....improved way

define service{
        use                                           local-service       
        hostgroups                              Wireless
        service_description                PING
        check_command                    check_ping!100.0,20%!500.0,60%
        }

You can even specify your service to check multiple hostgroups

define service{
        use                                           local-service       
        hostgroups                              Wireless, Windows, Routers
        service_description                PING
        check_command                    check_ping!100.0,20%!500.0,60%
        }
