# Plugin to graph number of courier login/logouts
# Requires: logtail
#
# This plugin should be symlinked to have the service name that you
# want to track. If you want to watch imaplogin entries you would do:
# ln -s /usr/share/munin/plugins/courier_ /etc/munin/plugins/courier_imaplogin
# if you wanted to track courierpop3login entries, then you would do:
# ln -s /usr/share/munin/plugins/courier_ /etc/munin/plugins/courier_courierpop3login
