hostgroups in service definitions

One of my services using a hostgroup

define service{
        use                             base-service
        service_description             EXCHANGE_SA
        hostgroup_name                  nt_client_servers
        max_check_attempts              2
        normal_check_interval           15
        retry_check_interval            1
        notification_interval           120
        notification_options            c

Subject: [Nagios-users] hostgroups in service definitions


Hello,

I'm trying to set up Nagios for an (in the end) fairly large and
complex network. I haven't used Nagios/Netsaint before, but with the
documentation and the FAQ I got a pretty good start, at least for the
not large and complex test bed. 

My problem:
My logical thinking tells me that in a "define service{}" I should be
able to insert a hostgroup, with the result that this service would be
defined on all hosts in the hostgroup (as I have a couple of basically
identical hosts). This does not seem to work. 

What I have done:
- I used 
  host_name mygroup 
  in the service definition. Result when running nagios -v:
  Error: Host 'my_group' specified in service 'SMTP' not defined anywhere!
- I used 
  host_group my_group
  in the service definition. Result when running nagios -v:
  Error: Could not add object property in file '[...]/services.cfg' on line
x.
- I used 
  host_name host1,host2,host3
  in the service definition. This seems to work. 

What more did I do:
- I read the documentation regarding service definition (again) and
  looked for other places in the documentation that could be of help.
- I read and searched the FAQ.
- I tried to search the mailing list archive. Unfortunately the search
  funktion was either stalling or time out-ing, more or less.

I'm sure it must be some tiny overseeing on my side, as I would expect
this to be in the FAQ if it was really neccessary to list all
computers seperately - what would be the point of hostgroups then, and
it would be quite error prone when adding/deleting hosts. 


Regards,
         Rasmus
