#
# Wildcard plugin to monitor ipfw rules counters
# Usage:
#
# Method 1:
#
# Link ipfwcnt_<rule number> to this file. E.g.
#
# ln -s ipfwcnt_ ipfwcnt_100
#
# ... will monitror ipfw rule 100
#
# Method 2:
#
# 1. Add count rules to ipfw E.g.
#
# ipfw add 100 count ip from any to table(1,0) in via rl0
# ipfw add 200 count ip from any to table(1,1) in via rl0
# ipfw add 300 count ip from any to table(1,2) in via rl0
# ipfw add 400 count ip from any to not table(1) in via rl0
#
# 2. Link ipfwcnt_<name> to this file. E.g.
# ln -s ipfwcnt_ ipfwcnt_rl0-in
#
# 3. Add rules configuration to plugins.conf:
# [ipfwcnt_rl0-in]
# user root
# env.rules group0 group1 group2 nogroup
# env.rule_group0 100
# env.rule_group0_label group0
# env.rule_group0_info Incoming traffic of group 0
# env.rule_group1 200
# env.rule_group1_label group1
# env.rule_group1_info Incoming traffic of group 1
# env.rule_group2 300
# env.rule_group2_label group2
# env.rule_group2_info Incoming traffic of group 2
# env.rule_nogroup 400
# env.rule_nogroup_label nogroup
# env.rule_nogroup_info Incoming traffic of no group
#
# ... will monitor ipfw rules 100,200,300,400
#
# This plugin needs to be run as root.
#
# Magic markers (optional - used by munin-config and some installation
# scripts):
