Copy the check_cpu from the plugins directory into your nagios plugins directory. This plugin runs locally on a machine via NRPE, so you will need to do this for any machine you wish to monitor.
On the nagios server, copy the pnp4nagios/check_commands/check_cpu.cfg into your pnp4nagios check_commands directory (ususally /etc/pnp4nagios/check_commands). Copy the pnp4nagios/templates/check_cpu.php into your pnp4nagios templates directory.
Add the following to your NRPE configuration file and restart NRPE (adjust the plugin path as necessary):
command[check_cpu]=/usr/lib64/nagios/plugins/check_cpu
Assuming you already have a check_nrpe command defined, you simply need to add a service definition:
define service{
use generic-service-graphed
service_description CPU Usage
hostgroups Linux Servers
check_command check_nrpe!check_cpu
}
