[Nagiosplug-help] Re: syntax question check_nrpe & check_disk

[Frederik Vanhee]

Thanks Ian,

but I want to configure everything from my Nagios server. The warning and
critical tresholds for the disk must be configurable from the nagios-server
and not on each host's nrpe.cfg file.

In the mean time, I found the solution. From nrpe 2.0 on, it is possible to
add extra arguments to the check_nrpe plugin with the '-a' option.
So, in my example, I pass 2 extra arguments $ARG2$ and $ARG3$ with the
treshold values for the warning and critical arguments from the check_disk
command.

nrpe.cfg
command[check_disk]=/opt/nrpe/check_disk -w $ARG1$ -c $ARG2$

check_commands.cfg
command_line /opt/nagios/libexec/check_nrpe -H machineA -p 5666 -t 60 -n -c
$ARG1$ -a $ARG2$ $ARG3$

services.cfg
check_command check_nrpe!check_disk!20%!10%
