#
# Wildcard plugin to monitor ipfw nat aliasing links count
#
# Usage: Link ipfwnat_<nat number> to this file. E.g,
#
# ln -s ipfwnat_ /etc/munin/node.d/ipfwnat_123
#
# ... will moninot nat number 123
#
# This plugin needs to be run as root. Sample plugins.conf:
#
# [ipfwnat_*]
# user root
#
# Furthermore, nat configuration must contain "log" option. E.g.
#
# ipfw nat 123 config ip 198.76.28.4 log
#
# This plugin is based on the if_ plugin.
#
# Magic markers (optional - used by munin-config and some installation
# scripts):
#
#%# family=auto
#%# capabilities=autoconf suggest
