Notifying within hosts and services

[Percy Kwong]

I have a service within a group that needs a script to be run to restart 
that service if it goes down.  I was wondering if I define a method to 
run the script and place an "notifyalso: Mymethod" within the service 
definition if that would be possible?

Basically, I would like to run the restart script only for that service 
and for no others within the group or host.

Do I need to create a separate group for that one service and place the 
notifyalso statement within the new group definition or can i just 
specify the notifyalso command within the service definition for the 
existing group?

Thanks In Advance.
