inheritance option, default values and API

[mon-team]

Dear all,
i have a question about the inheritance option ("+","standard","null") which can be set in the Servicegroups, Contacts and Contactgroups tab when defining a new service.
I 'd like to know if is there a way to modify the default selection (set to "standard") to the "+" value.

In our environment we have designed our monitoring implementation in order to always inherit settings from the previous level, so all our services have the inherit option set to "+". However every time we create a new service we have to manually change this value, and this can be a source of problem.

Moreover, using the Nagios XI API, is here a way to set this value to "+"? (I use the config/import endpoint to create services).

Regards
Francesco

How are you adding the new services - via a wizard, manually (in the CCM), cloning an existing service, running the Bulk Import wizard, using the REST API, etc.? We need more information in order to point you to the right direction.

Moreover, using the Nagios XI API, is here a way to set this value to "+"? (I use the config/import endpoint to create services).

When you import a config via the REST API, the additive inheritance options will be imported as well. See the example below:

Is this not working for you?

Hello,
i create services manually and using the rest API.
In particular, if i use the API i know that i can modify the inheritance behavior in this way:

servicegroups +localserver

The problem is that, as a best practice, we insert the Service Group inside a Service Template, as usually a Service Template is applyed to a block of omogeneous services. In this way, also if i define a Service Template with the inherance set to '0+', the service created via API will have the inheritance set to 'standard'.

You can use a service template to apply an additive inheritance via the REST API. I am not sure what you mean by:

if i define a Service Template with the inherance set to '0+'

but here's an example (with a template):

Code: Select all

define service {
    name                            my_template
    service_description             My Template
    servicegroups                   +PING
    check_command                   check_xi_service_none!!!!!!!!
    is_volatile                     0
    max_check_attempts              5
    check_interval                  5
    retry_interval                  1
    active_checks_enabled           1
    passive_checks_enabled          1
    check_period                    xi_timeperiod_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             xi_timeperiod_24x7
    notifications_enabled           1
    register                        0
}

Code: Select all

{

I can see the "MyTestService" added to the "PING" servicegroup in the GUI.

Hope this helps.
