Plug-in problem

[Volker.Aust at premiere.de]

Hi Jo,

yes, I think you have to define your nrpe commands on the Nagios host in the
command.cfg:

<nrpe README>

In order to use the check_nrpe plugin from within Nagios, you'll have
to define a few things in the host config file.  An example
command definition for the check_nrpe plugin would look like this:

define command{
	command_name	check_nrpe
	command_line	/usr/local/nagios/libexec/check_nrpe $HOSTADDRESS$
-c $ARG1$
	}

In any service definitions that use the nrpe plugin/daemon to
get their results, you would set the service check command portion
of the definition to something like this (sample service definition
is simplified for this example):

define service{
	host_name		someremotehost
	service_description	someremoteservice
	check_command		check_nrpe!yourcommand
	... etc ...
	}

where "yourcommand" is a name of a command that you define in 
your nrpe.cfg file on the remote host (see the docs in the 
sample nrpe.cfg file for more information).

</nrpe README>
