is there a way to service/host escalations and their members via the rest api or a cgi? i am trying to automate creating them and i need a way to find out what hosts/services do not exist in an escalation policy to ensure they are added.

Perhaps the JSON Query is what you are after, with the Object CGI:

thanks for the info, this appears to show almost what i need. i currently assign services to host groups and would like to see what services are assigned to a host group and then make sure that host group is in a service escalation policy.

is there a way to query which host groups are in a service escalation policy?
is there a way to query which services are assigned to a hostgroup?

CGI: Object JSON CGI
Query: serviceescalationlist
Host Group: <the hostgroup you want to query>

Not that I can see.

The reason behind this goes back to what Nagios does when it starts up.
It reads all the config files and creates all the "final objects". Things like services that are created using hostgroups, that information is lost as it's no longer required, it's purpose was to allow simple/complex configurations. The "final objects" reside in /usr/local/nagios/var/objects.cache.

Here's an example:

This is in the config file:

Code: Select all

define service {
	service_description		Current Load assigned to hostgroup_localhost
	use				local-service
	hostgroup_name			hostgroup_localhost
	check_command			check_local_load!5.0,4.0,3.0!10.0,6.0,4.0!!!!!!
	register			1
	}

This is in objects.cache:

Code: Select all

define service {
        host_name       localhost
        service_description     Current Load assigned to hostgroup_localhost
        check_period    24x7
        check_command   check_local_load!5.0,4.0,3.0!10.0,6.0,4.0!!!!!!
        contact_groups  admins
        notification_period     24x7
        initial_state   o
        importance      0
        check_interval  5.000000
        retry_interval  1.000000
        max_check_attempts      4
        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
        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
        }

Not sure what the answer is apart from creating some script that Queries the configs against the running state.
