check_proc --metric=CPU - alternatives?

This is what I tried but as I described all processes have the same

And I want to get an alert if ANY of these processes uses more than the
given value.

Not really true ;-)
As this machine has 8 real CPU-Cores with HT enabled there can be up to
16 Processes with more than 90% CPU usage ;-)

I will have a look in the perl code. Maybe it is a only small
