CPU Idle Plugin for Nagios and Cacti

CPU Idle Plugin for Nagios and Cacti

This script provides the IDLE CPU of the target machine.

Should work with many flavors of Linux and UNIX.

This script requires:

1) Change NAGCACTIUSER to match the username you use for Nagios/Cacti data collection.

2) sar installed on the remote machine (provided by sysstat in some Linux distros)

3) ssh key set up from the Nagios/Cacti server to the desired user on the remote machine

4) If the user that connects to the remote machine is different from the

one that Nagios/Cacti run under, then you need something like this in sudoers:

cacti ALL=NOPASSWD: /bin/su -  *

In Nagios command.cfg:

 define command{
     command_name    check_cpu
     command_line    $USER1$/check_cpu_cacti_nagios.sh $HOSTADDRESS$ $ARG1$ $ARG2$ nagios

In Nagios services.cfg

define service{
    use                    service_1_min
    host_name              remotehost1,remotehost2
    service\_description   cpu
    check_command          check_cpu!30!10
    max_check_attempts     10
    contact_groups         admins
