Tool to Calculate 'Effective' Config for a Host or Service?

[kjhosein]

Hello all,

I looked around my Nagios Core & Nagios XI interfaces, but can't find a mechanism or a tool that would show me or calculate the 'effective' config for a host or service. This would be particularly useful where you make use of templates, especially nested templates.

I searched through the Nagios Exchange, and as you can imagine, this is a tough thing to search for given the keywords!

Am I blind and if not, does such a tool exist?

Thanks!

I'm not quite sure what you mean by the 'effective' config for a host. Could you be a little more specific on what exactly you are looking for? Or to do?

Taking an example out of http://nagios.sourceforge.net/docs/3_0/ ... tance.html, let's say you have a couple of definitions where one 'uses' the other, template style:

Code: Select all

define host{
		host_name		bighost1
		check_command		check-host-alive
		notification_options	d,u,r
		max_check_attempts	5
		name			hosttemplate1
		}

define host{
		host_name		bighost2
		max_check_attempts	3
		use			hosttemplate1
		}

Then the config for bighost2 would effectively be:

Code: Select all

define host{
		host_name		bighost2
		check_command		check-host-alive
		notification_options	d,u,r
		max_check_attempts	3
		}

What I want 'to do' is see those calculated configs for a host or service.
Thanks!

You can see the current, 'effective' objects by looking at the objects.cache file:

Code: Select all

less /usr/local/nagios/var/objects.cache

Great, thank you!

Would be nice to have it in the GUI, but I'm not complaining! I'll take it
