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