Unable to apply configuration

The output seems the Apply Configuration to have completed aside from the warnings. Is it working for you now?

The Errors and Warnings are generated by Nagios Core, here is some information on what Core expects in its configuration.

Services must be defined as a real service not a template to be active. A service can inherit from a template or stack of templates.

When Core generates a warning or error like the ones you have been experiencing, it's not frivolous or inaccurate. Simply reading the output and investigating the referenced file should provide some insight.

Hi,

I was attempting to make a minor change; adding the display name to a different host via the CCM then attempting to apply the configuration.


I got the following error:

apply_config_error.png

After checking the file the requirements are there. Host and service description:

Not sure why I still have an issue when trying to apply this config.

Thanks

How are you creating that service? This the definition in the config:

Code: Select all

define service {
	service_description		check load
	display_name			check load -w 40,30,20 -c 50,40,30
	check_command			custom_check_xi_by_ssh!'./check_load -w 40,30,20 -c 50,40,30'!!!!!!!
	notification_period		24x7
	contacts			astuck
	contact_groups			null
	register			1
	}	

As noted in the previous Object Definitions documentation, the service doesn't contain all the required fields.

The service that is creating the issue is a copy from an existing service named:
custom_linux_load_linadmin_waking_hours.cfg

It was simply copied and altered for testing, but now it's not allowing us to apply the config if we alter something or attempt to remove a host, etc.

I've added all the required parameters to problem service by going directly to the service and adding all the parameters thru the CCM ( custom_linux_load_linadmin_waking_hours_test.cfg see below ), but it's still giving me the same error when I try to apply the config:

Error: Service has no hosts and/or service_description (config file '/usr/local/nagios/etc/services/custom_linux_load_linadmin_waking_hours_test.cfg', starting on line 16)

Can you please share the path of the service definition you sent in the last reply? I'm not sure we're looking at the same service definition.

Thanks

In what way was it copied?

In CCM a copy of the service also brings across the associated hosts which you don't have in the failed apply config.

Also please note the header in the file:

Code: Select all

# --- DO NOT EDIT THIS FILE BY HAND ---
# Nagios CCM will overwrite all manual settings during the next update if you
# would like to edit files manually, place them in the 'static' directory or
# import your configs into the CCM by placing them in the 'import' directory.

All those files are generated on each apply config. You need to correctly define it in XI > Configure > CCM in order for the new configuration to apply.

Hi,

The service was copied using the CCM. It was not manually edited by directly accessing the files on the server.

Here's the original service as seen on the server:

Code: Select all

[root@prdmgtnag01 services]# cat ./custom_linux_load_linadmin_waking_hours.cfg

define service {
	service_description		check load
	use				tmpl_linadm_alert_waking_hours
	hostgroup_name			default_linux_alert
	display_name			check load -w 40,30,20 -c 50,40,30
	check_command			custom_check_xi_by_ssh!'./check_load -w 40,30,20 -c 50,40,30'!!!!!!!
	register			1
	}

At this point, I just want to delete the problem service (custom_linux_load_linadmin_waking_hours_test.cfg) and save the changes but it won't even let me do that.

Thanks

Apply Configuration.

That will bring your system back to the most recent known good state and ensure no ill-formed definitions are laying about.

Hi,

I don't see this:
XI > Configure > Core Config Manager > Config File Management

The closest thing I see is 'Write config files' which has a delete button with the following description:
"Delete all host/service configuration files"

Is it safe to run this? The description makes it sound like a dangerous thing to do.

Thanks
