#
# Wildcard-plugin to monitor IP addresses through iptables. To monitor an
# IP, link fwbuilder_<ipaddress> to this file. E.g.
#
# ln -s /usr/share/node/node/plugins-auto/fwbuilder_ /etc/munin/node.d/fwbuilder_192.168.0.1
#
# ...will monitor the IP 192.168.0.1.
#
# Aditionally, you need Accountingrules in fwbuilder
# fwbuilder creates Chains in INPUT-, OUTPUT- and FORWARD-Chain
# with Rules that "RETURN"
# You will have to specify rule options with name "ACCOUNTING" for the
# rules to use, otherwise no rules will be found.
# try "fwbuilder_ suggest" to see if all is ok.
#
#
# Furthermore, this plugin needs to be run as root for iptables to work
#
# This plugin is based on the if_ plugin.
#
