Service Configuration

[Derek Olsen]

  Tim.
  Let's say you have 20 application servers and you want to monitor the 
tim_http service on each one.
  The nagios way is to include each of the 20 application servers into 
what's referred to as a hostgroup and then when you define your service 
instead of referencing a host reference a hostgroup.  For this example 
we'll assume all 20 applications servers have been setup and have host 
names that start with tim (ie: tim01, tim02, tim03, etc).

 In your hostgroups file you would have this entry

define hostgroup {
        hostgroup_name  tim-servers              # Name is  arbitrary 
and up to you
        alias          The Tim servers                # Ditto on alias
        members        tim.*                            # Now we have an 
hostgroup which contains all the timXX hosts
}


  In my services file I would have this entry (I'm assuming you'll have 
a service template called service-template

  define service {
        use                                       service-template
        hostgroup_name                    tim-servers                    
# Name of hostgroup from above example
        service_description                Http Services on the Tim Farm
        contact_groups                      tim
        check_command                   check_tim_servers          # 
This command is defined in the checkcommands.cfg file
}


      So for situations where you have more than 1 host which needs to 
have a service checked hostgroups are the simple way to manage the 
services so you dont have to repeat the service over and over for each 
host.   Once you setup a few the light bulb will go off.

    Anyhoo hope this helps.
    Deet.
