#
# Plugin to monitor the number users logged in to a unix box.
# Based on an idea of a hotsanic script.
# Never tested for any other class than pts users. Until now,
# I've only tested on various Linux boxen, but it might work
# on other Un*x-alike systems as well. I'd like to hear from
# you, if you can report this script running on any other
# platform than Linux.
#
#
# Usage: copy or link into /etc/munin/node.d/
#
# Parameters:
#
# config (required)
