[Bug 1027823] [NEW] defining a service with parameters leads to errors is service is remote

[Thomas Schweikle]

Public bug reported:

Defining a service:
define service{
        hostgroup_name                  current-load16
        service_description             Current Load
        check_command                   check_nrpe!check_load!40.0 32.0 28.0 48.0 40.0 36.0
        use                             generic-service
        notification_interval           0 ; set > 0 if you want to be renotified
        }

Then a hostgroup:
define hostgroup {
        hostgroup_name  current-load16
        alias           Current Load
        members         vh01
        members         vh02
}

and the hosts:
define host{
        use                     generic-host
        host_name               vh01
        alias                   vh01
        address                 vh01
        parents                 zm2
        }

define host{
        use                     generic-host
        host_name               vh02
        alias                   vh02
        address                 vh02
        parents                 vh01
        }

gives back an error, instead the awaited result:
Warning threshold must be float or float triplet!

Usage:
check_load [-r] -w WLOAD1,WLOAD5,WLOAD15 -c CLOAD1,CLOAD5,CLOAD15

Digging further, activating debug on the client, leads to:
Jul 23 10:44:15 vh02 nrpe[24461]: Host is asking for command 'check_load' to be run...
Jul 23 10:44:15 vh02 nrpe[24461]: Running command: /usr/lib/nagios/plugins/check_load -w ',,' -c ',,'

The parameters given are empty on the client! The nrpe-service definitions are:
log_facility=daemon (BTW: ignored. Fixed upstream, but Ubuntu remains at an old unfixed version)

dont_blame_nrpe=1
command[check_load]=/usr/lib/nagios/plugins/check_load -w '$ARG1$,$ARG2$,$ARG3$' -c '$ARG4$,$ARG5$,$ARG6$'

the first allows for parameters, the second is the service definition. Looks all OK for me (and others). This problem seems fixed in a later version of nagios, but since Ubuntu is keeping version 3.2.3 ...
Just click on the link "Check for updates" on the nagios home-page:
Your installation of Nagios Core 3.2.3 is outdated and should be upgraded. The latest version of Nagios Core is 3.4.1 was released on 2012-05-14.
