set use_logging=1 in cgi.cfg and set the path to the cgi log file to an apache writable path. then post the output when triggering the error on the browser.

Ok. And now I want to see that config object in Icinga 2 for the involved host and service. Somehow the 'check_command' is not dumped.

Btw - any reason why to use the autorelease packages, and not snapshot as it's still in pre beta stage? That way you could test fixes more fast.

[icinga-migration]

Updated by tobiasvdk on 2014-05-09 12:46:56 +00:00

service config:

apply Service "disk-var-partition" to Host {
    import  "generic-service"

    check_command = "generic-disk-nrpe-check"
    vars.disk = "/var"

    assign where host.vars.has_var_partition
}

check command config:

template CheckCommand "generic-disk-nrpe-check" {
    import "plugin-check-command"

    command = PluginDir + "/check_nrpe"

        arguments = {
        "-u"
        "-H" = "$address$"
        "-t" = 20
        "-c" = "check_disk"
        "-a" = "$warning_threshold$ $critical_threshold$ $disk$"
        }

    vars.disk = "/"
    vars.warning_threshold = "20%"
    vars.critical_threshold = "10%"
}

No ... I will change apt config to use icinga-wheezy-snapshots.

Some background to my setup. I configured a clustered setup with two endpoints: one master and one slave (which is doing/should do the checks).

Updated by tobiasvdk on 2014-05-09 13:19:54 +00:00

Ohh, I upgraded to 0.0.10+icingasnap201405090855.020ca0b~wheezy and libcluster.so is missing!

True. The cluster part is undergoing major changes in git next currently. Remove that configuration while testing this issue.

[icinga-migration]

Updated by tobiasvdk on 2014-05-09 14:46:24 +00:00

Is anything wrong with the service and check command configuration I did?

Updated by gbeutner on 2014-05-09 17:35:52 +00:00

Hm, this seems to be a bug in the config validator. Your check command is a template: "template CheckCommand". Try changing that to "object CheckCommand" and see if that fixes the problem.

Changing/correcting the config works. Thank you for the hint!
