processes - Plugin to monitor the number of processes on the machine.
Using "ps | wc -l".

No configuration
=head1 NOTES
=head2 DESCRIPTION
This will report back the number of processes currently running on a
server. By defualt it will report back the total number of processes
running (global). Optionally you can edit the script and add items to
look for to the "lookFor" array. These should be simple things that
can be grep'd for.
=head2 RESCTRICTIONS
None known. /usr/bin/ps should be executable by everyone by default.
Optionally you can add items to the lookFor array, and those items
will be graphed as well. This can be useful for watching how many
processes of a particular type are running.
