Check Procs by % CPU

I have check_procs checking using the %CPU metric but when I click on it it only shows # of processes running. It is properly warning but the display is just showing # of processes and not the % used by top process. How can I change this?

If you want to change it, then rewrite the source code for the plugin, recompile/install.
But the reason it is doing that, is because of this, from the output of
./check_proc --help
"This plugin checks the number of currently running processes"

Also, looking at the percentile CPU load isn’t very useful most of the time. Instead you may want to use either check_load or check_load2 to check on the average load.
