command[swap]=/usr/libexec/nagios/check_swap -w 20% -c 10%
command[root_disk]=/usr/libexec/nagios/check_disk -w 20% -c 10% -p / -m
command[procs_zombie]=/usr/libexec/nagios/check_procs -w 5 -c 10 -s Z
command[procs_total]=/usr/libexec/nagios/check_procs -w 150 -c 200
command[procs_init]=/usr/libexec/nagios/check_procs -w 1: -c 1:2 -C init
Example content for op5_commands.cfg (with arguments allowed): To use this you need to set dont_blame_nrpe=1 in nrpe.cfg.
command[load]=/usr/libexec/nagios/check_load -w $ARG1$ -c $ARG2$
command[users]=/usr/libexec/nagios/check_users -w $ARG1$ -c $ARG2$
command[swap]=/usr/libexec/nagios/check_swap -w $ARG1$ -c $ARG2$
command[disk]=/usr/libexec/nagios/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$ ?m
command[procs_zombie]=/usr/libexec/nagios/check_procs -w $ARG1$ -c $ARG2$ -s Z
command[procs_total]=/usr/libexec/nagios/check_procs -w $ARG1$ -c $ARG2$
command[procs_name]=/usr/libexec/nagios/check_procs -w $ARG1$ -c $ARG2$ -C $ARG3$
Restart NRPE to load new settings
sudo /etc/rc.d/init.d/nrpe restart
Make NRPE start at boot by linking it to run-level 2
cd /etc/rc.d/rc2.d/
ln -s ../init.d/nrpe S99nrpe
Host can now be added to OP5 Monitor and be monitored with check_nrpe service-checks.
