Munin contributed plugins

#!/bin/sh

#

# Wildcard-plugin to monitor arp on interfaces. To monitor an

# interface, link arp_bsd_<interface> to this file. E.g.

#

#    ln -s /usr/local/share/munin/plugins/arp_bsd_ /usr/local/etc/munin/plugins/arp_bsd_vlanX

#

# ...will monitor arp on interface vlanX.

#

# Any device found in /sbin/ifconfig can be monitored.

#

# Bugs : This plugins has been tested extensively on FreeBSD only
