CPU usage

Hi, I need something linke this:

./check_cpu -w 60% -c 80%

warning status when the cpu usage is greater then 60%
critical status when the cpu usage is greater then 80%

What kind of plugin may I use?

try check_load

“-w, --warning=WLOAD1,WLOAD5,WLOAD15”

what the documentation means with WLOAD1,WLOAD5,WLOAD15?

load average as used by the uptime and top commands.

I’m so sorry, but i didn’t understand how can I do this with check_load
“./check_cpu -w 60% -c 80%”
