Template inheritance question and CCM bug?

[BanditBBS]

Two things:

1.) When I modify a service and select the hosts button, any way to make it only inherit hosts from template used if there is no host specified on the service?

2.) When on the hosts screen and I select +, null or standard and hit close then save, if I go back into that service and into hosts, that option is not selected.

1) So you want services to apply to hosts that use a certain host template, correct? If not, could you clarify?
2) This is a confirmed bug with the CCM, the workaround is to use the legacy ccm until XI 2014.

1) Umm, let me explain better. I have a group of services that all use a specific service template. That service template has the hosts that should use it configured in it. There are one or 2 services that also use that service template, but I want to specify the hosts that should get this service on the service itself and ignore what is defined in the service template.
2) bah - LOL

BanditBBS, I believe this should work just fine... I tested this scenario on my test box, and seems to work. I created a "Dummy Service", that is NOT added to a host.

Code: Select all

define service {
	service_description		Dummy Service
	use				dummy_service_template
	servicegroups			linux-servers-all
	check_command			check_local_load!6.0,5.0,4.0!12.0,10.0,8.0!!!!!!
	check_period			tracs monitoring times
	first_notification_delay	0
	notification_options		w,c,u,r,f,s,
	notifications_enabled		1
	contact_groups			null
	register			1
	}

Here's the "dummy_service_template" definition:

Code: Select all

define service {
       name                          		dummy_service_template
       host_name                     		NCPA
       service_description           		dummy_service_template
       is_volatile                   		0
       max_check_attempts            		3
       check_interval                		10
       retry_interval                		2
       active_checks_enabled         		1
       passive_checks_enabled        		1
       check_period                  		24x7
       parallelize_check             		1
       obsess_over_service           		1
       check_freshness               		0
       event_handler_enabled         		1
       flap_detection_enabled        		1
       process_perf_data             		1
       retain_status_information     		1
       retain_nonstatus_information  		1
       notification_interval         		60
       notification_period           		24x7
       notification_options          		w,c,u,r,
       notifications_enabled         		1
       failure_prediction_enabled    		1
       register                    		0

}

When I check the "/usr/local/nagios/var/objects.cache", I can see that "Dummy Service" is "added to" the NCPA host (grabbing it from the template):

Code: Select all

define service {
        host_name       NCPA
        service_description     Dummy Service
        check_period    tracs monitoring times
        check_command   check_local_load!6.0,5.0,4.0!12.0,10.0,8.0!!!!!!
        notification_period     24x7
        initial_state   o
        hourly_value    1
        check_interval  10.000000
        retry_interval  2.000000
        max_check_attempts      3
        is_volatile     0
        parallelize_check       1
        active_checks_enabled   1
        passive_checks_enabled  1
        obsess  1
        event_handler_enabled   1
        low_flap_threshold      0.000000
        high_flap_threshold     0.000000
        flap_detection_enabled  1
        flap_detection_options  a
        freshness_threshold     0
        check_freshness 0
        notification_options    r,w,u,c,f,s
        notifications_enabled   1
        notification_interval   60.000000
        first_notification_delay        0.000000
        stalking_options        n
        process_perf_data       1
        retain_status_information       1
        retain_nonstatus_information    1
        }

Yes, that is how it works.

I have a list of, let's say, 25 services that use that service template and they are all added to the NCPA host. There is one service though, that I'd like to use that service template on so it inherits everything set in the template, EXCEPT the host. On this service, I'd like to specify the host it should go to in the service definition itself. If I do that, it has HOST2 and NCPA as it inherits that from the host. Is there a way to stop that inheriting?

To be honest, I am not able to recreate the issue. I just went to the CCM->Service->Dummy Service->Modify->Manage Hosts, and added a "Windows 7" host. When I check the objects.cache, I can see the "new" host (added on a service level), but not the "old one" (from the template).

Code: Select all

define service {
        host_name       Windows 7
        service_description     Dummy Service
        check_period    tracs monitoring times
        check_command   check_local_load!6.0,5.0,4.0!12.0,10.0,8.0!!!!!!
        notification_period     24x7
        initial_state   o
        hourly_value    1
        check_interval  10.000000
        retry_interval  2.000000
        max_check_attempts      3
        is_volatile     0
        parallelize_check       1
        active_checks_enabled   1
        passive_checks_enabled  1
        obsess  1
        event_handler_enabled   1
        low_flap_threshold      0.000000
        high_flap_threshold     0.000000
        flap_detection_enabled  1
        flap_detection_options  a
        freshness_threshold     0
        check_freshness 0
        notification_options    r,w,u,c,f,s
        notifications_enabled   1
        notification_interval   60.000000
        first_notification_delay        0.000000
        stalking_options        n
        process_perf_data       1
        retain_status_information       1
        retain_nonstatus_information    1

I worked around it a different way that ended up being better for me anyway. But in the future, if I may run into this again. But I don't care enough to continue investigating why I was having an issue! LOL

Thanks for looking into it though. I'll open a new thread if I have the issue in the future.

[lmiltchev]

Fair enough.
