# Wildcard-plugin to monitor network interfaces. To monitor an
# interface, link if_<interface> to this file. E.g.
#
# ln -s /usr/share/munin/node/plugins-auto/if_ /etc/munin/node.d/if_eth0
#
# ...will monitor eth0.
#
# Any device found in /usr/bin/netstat can be monitored.

# This package has added support for NetBSD, via a number of new plugin
# scripts where specific steps needs to be taken to collect information.
#
# I also modified the ntp_ plugin script to make it possible to not
# plot the NTP poll delay, leaving just jitter and offset, which IMO
# produces a more telling graph.

# Magic markers (optional - used by munin-config and some installation
# scripts):
