You'll have to search for something like this
define host{
use generic-om-host ; Name of host template to use
name generic-server
check_command check-host-alive
register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!
}
The check command that is defined here is what mathers.
