#!@@PERL@@
#
# Plugin to monitor the volume of data sent from Apache servers. It handles
# a list of ports passed in from a plugin configuration file.
#
# Requirements:
# - Needs access to http://localhost/server-status?auto (or modify the
# address for another host). See your apache documentation on how to
# set up this url in your httpd.conf. Apache needs ExtendedStatus
# enabled for this plugin to work.
#
# Tip: To see if it's already set up correctly, just run this plugin
# with the parameter "autoconf". If you get a "yes", everything should
# work like a charm already.
#
# Parameters supported:
#
# config
# autoconf
#
# Configurable variables
#
# url - Override default status-url
# ports - HTTP port numbers
#
