hostgroups in servicegroup definition FIXED

[Lori Adams]

This is what I expected.  This is a workaround.  You're not listing
hostgroup_name in the servicegroup config, you're generating the lists
of hosts in a hostgroup using a script and then populating
servicegroups.cfg.

I would rather not have a script that does the generating, but have the
hostgroup name allowed in a servicegroup config.  In the meantime, I'll
probably end up using a script to do this for me.  

Is this going to be a possibility in a future release?

Define servicegroup {
	name		blah
	alias		blah
	members	hostgroup_name,service
	}

I went and had a look at this for you since I would like for people to 
be able to use my servicegroup-generator for this as well and what you 
need is to do the following in your services.cfg or equivalent file:

define service{
       blah
       blah
       hostgroup_name    SomeHostGroupName
       blah
       blah
}

firstly you must use "hostgroup_name" instead of "host_name" on the left

hand side if you are using hostgroups in your service definitions.

You can use both host_name and hostgroup_name on separate lines within 
each service definition block, I've just checked this and it works.

hostgroup_name is not in the Nagios 2.x docs in the services section 
even though it works, but other object file definitions do contain 
hostgroup_name for their references and it is in the Nagios 3.x docs so 
it must just be a minor oversight to not have it in the service 
definition section of the Nagios 2.x docs.


I have rewritten my servicegroup-generator.py to work with hostgroups 
properly now and work around the fact that Nagios does not accept 
hostgroups in the servicegroup file.

If you download the latest version 1.3 on nagiosexchange.org it will 
handle this as well by expanding the hostgroups. In order to do this, it

will use your hostgroup file. It defaults to hostgroups.cfg for the 
hostgroup file but you can specify another filename using the new -f
switch.

I have added a hostgroup to my services file and it seems to work well, 
it puts the host names that belong to the hostgroup into the 
servicegroup file and all works well... you can now mix and match 
host_name and hostgroup_name definitions in your services file and the 
generator will handle it and create a full working servicegroups file.

The latest version is available at:

http://www.nagiosexchange.org/Configuration.20.0.html?&tx_netnagext_pi1[
p_view]=896

Let me know how it goes for you with this.


Hope that helps
