freeBSD nagios CPU

[gsuwal]

Hi all,

I am not being able to monitor CPU of freeBSD machine from my

CentOS server. I have used check_aix_cpu but always gives garbage

value, seems wrong in scripting.

i want to monitor CPU usage of my freeBSD machine from my centOS

server. I am able to monitor many services of that machine like

mailq, processes, free space, uptime but not CPU.

Kindly please help.

Regards,
Franklin

Franklin,

If you've tried other plugins and they don't work for you perhaps its a good time to right your own, this should get you started:

Code: Select all

sar -p | tail -2 | head -1 | awk '{ print 100-$9 }'

That will return 100 - CPU Idle would would give CPU load time on that machine, and I believe that will work on most *nix systems. All you'd have to do is return that value, and if you wanted to get fancy you could add critical/warning values.
