To Reproduce

Apply custom vars to dependencies is what I'm guessing is crashing it

Expected behavior

It should not crash and should accept custom vars in dependencies

Your Environment

Include as many relevant details about the environment you experienced the problem in

• Icinga DB version: v1.0.0
• Icinga 2 version: r2.13.4-1
• Operating System and version: Red Hat Enterprise Linux Server release 7.9 (Maipo)

Additional context

An example of a decency we add via the API:

[root@icinga01 dependencies]# more newres-3-314-ap1\!newres-245-sw1.conf
object Dependency "newres-245-sw1" {
        child_host_name = "newres-3-314-ap1"
        parent_host_name = "newres-245-sw1"
        vars = {
                database_run = "Thu Jul 28 00:04:00 2022"
                database_source = "cmdb"
                device_type = "aruba_ap"
        }
        version = 1658982689.918957
        zone = "icinga01"
}

[Al2Klimov]

Hello,

what are the custom vars for?

Best, A/K

[mzac]

@Al2Klimov We use vars in our dependencies so we are able to delete old ones as we update our Icinga instance every 2 hours and we have multiple CMDB sources to poll.

When we insert the dependency, the vars contain the CMDB source, the device type and the time it we added. When the script re-runs it updates this information and then deletes any dependencies that don't match the new timestamp.

This is an example from one of our Perl scripts on how we delete old entries:

    # --------------------------------------------------------------------------------
    # Delete old dependencies
    my %json_delete_data_dependency = (
        'filter' => "match(\"". $icinga_device_type ."\",dependency.vars.device_type) && match(\"". $database_source ."\",dependency.vars.database_source) && !match(\"". $datestring ."\",dependency.vars.database_run)",
    );

    my $delete_data_dependency = encode_json(\%json_delete_data_dependency);
    $delete_client->POST("$icinga_rest_base_url/dependencies\?cascade=1", $delete_data_dependency);
