According to the documentation, the -n option is used to give a regex
which selects which process(es) you are monitoring and the -u option
should work on the sum of the CPU for those selected processes only.

The example given is:

./check_snmp_process.pl -H 127.0.0.1 -C public -n http -w 3,8 -c 0,15
-m 9,25 -u 70,99

which should alert if the total cpu of all processes haveing 'http' in
the name is > 70.

To get the plugin to do exactly what you describe, you will need to
edit the perl code a bit.  Bear in mind that you can never have more
than one process using >90% cpu in the same period!
