Assign Contact Group to Host Groups using Host Template

[DonB]

I recently did the following post http://support.nagios.com/forum/viewtop ... =6&t=21459

I created a Host Group called hg_test and added a host to that group.
I created contacts and added them to a contact group called cg_test
I created a Host Template and added both hg_test and cg_test to the template.
When I run the custom notification from the host, I do not recieve any notifications. It appears that the host doesn't inherit the host template from the hg_test host group.
I then wanted to test and verify notifications can work by using a template to apply the contact settings, I added the host template to the host and the custom notification will work. I also have group option "standard" set at the host and contact group level on both the template and host.

Is there any additional settings that I need to make so that a host device will inherit the host template that is assign to a host group and will inherit the contact information? I did try using the hostgroup & contactgroup options (+, null, standard). But I'm not sure which settings and where to apply them. Which options should be set at the template level for both host groups and contact group vs at the host level.

Thank you,
Don

The first issue I see is that you "added both hg_test and cg_test to the template." Hosts/services/groups are not added to templates, they use them. So you need to include the "use" parameter in your hostgroup configs.

http://nagios.sourceforge.net/docs/3_0/ ... tance.html

Second, make sure you include "register 0" to your templates.

Third, it's a good idea not to use a generic template for both contact groups and host groups. You had mentioned using one for both hg_test and cg_test.

Can you post your configs/templates for reference?

See below the configuration for each object.

I reviewed the object inheritance and object definitions docs and I'm thinking the configuration I'm attempting might not be possable. My goal is to have a host group that when I make a host a member of, it would inhert a host template, being provided by the hostgroup config. The template would provide the contact group(s) for the host to use. Then when we create a new host, I just make it a member of the host group and it would inherit all of the host template settings. But I'm thinking the only time a host inherts a host template, is when the "use" parameter is configured under the host config. It appears that a hostgroup doesn't have the object parameter(s) needed to assign a host template to it's members.

Thank you,

My goal is to have a host group that when I make a host a member of, it would inhert a host template, being provided by the hostgroup config.

I don't believe this can be defined in the hostgroup definition - please, see the documentation:

http://nagios.sourceforge.net/docs/3_0/ ... #hostgroup

[DonB]

Yes, I agree that the hostgroup doesn't appear to have the "use" parameter or one that can apply a host template to a host. What got me a little confused, if you look at the object definitions document and review the host definitions, it does not have the "use" parameter, as well. The document actually needs to be updated. The only reference I found for the "use" parameter was in the Object Inheritance doc. So I thought there might possible be more parameters that were not listed for the hostgroup object.

Missing "use" parameter for hosts objects:
http://nagios.sourceforge.net/docs/3_0/ ... .html#host

The only reference for the "use" parameter and the examples are with the host object.
http://nagios.sourceforge.net/docs/3_0/ ... tance.html

I've been meaning to take a look at some of the documentation. Being the new guy I can't just go in and make changes, but I'll certainly look into it.

[DonB]

Thank you for your help.

So was your problem solved? If so, I'd like to lock this thread to keep the forums clean.

[DonB]

Yes, you can lock this thread. Thank you again for everyones assistance.
