- Get the CPU Usage for Windows, Solaris and Linux servers.
- Works automatically for an unlimited number of CPUs
- Perfomance data can be graphed with pnp4nagios using the template.
- Works for MS Windows, Solaris and Linux servers
- OS will be detected. No need to handle it over.

Sample command definition:

define command{
command_name check_cpu_usage
command_line /usr/lib/nagios/ops_plugins/check_cpu_usage -H $HOSTADDRESS$ -C $ARG1$ -w $ARG2$ -c $ARG3$
}

The syntax:
check_cpu_usage -H <host>|--hostname=<host> [-C <community>|--community=<community>] [-v <1|2c>|--snmpversion=<1|2c>] [-t <timeout>|--timeout=<timeout>] [-n|--noperfdata] [-w <threshold>|--warning=<threshold>] [-c <threshold>|--critical=<threshold>]

or

check_cpu_usage -h|--help

or

check_cpu_usage -V|--version

This plugin check the CPU usage of solaris, linux and windows servers

-h|--help Print detailed help screen
-V|--version Print version information
-H <host>|--hostname=<host> Hostname/IP-Adress to use for the check.
-C <community>|--community=<community> SNMP community that should be used to access the switch.
Default: public
-n|--noperfdata Don't print performance data.
-t <timeout>|--timeout=<timeout> Seconds before plugin times out.
Default: 60
-v <1|2c>|--snmpversion=<1|2c> SNMP version details for command-line debugging (can repeat up to 3 times)
Default: 1
-w <threshold>|--warning=<threshold> Warning threshold in percent.
Default: 80
-c <threshold>|--critical=<threshold> Critical threshold in percent.
Default: 90

Something about the perfdata template.
This template includes a control break. You will always have 4 cpus in on graph with 4 different colors.If you wanna
change it you have to play aorunt with $counter1 and $counter2 in the template.
