+# 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.
+#
