# Wildcard-plugin to monitor disks. To monitor a disk,
# link io_<function>_<disk> to this file. E.g.
#
# ln -s /usr/share/munin/plugins-auto/io_.kstat /etc/munin/node.d/io_busy_sd0
#
# ...will monitor busy and wait on sd0.
#
# These functions are implemented:
# busy bytes ops
#
# Any device found in /usr/bin/kstat can be monitored.
#
# Configuration variables
#
# io_*_ignore - Perl expression to select devices to ignore
#
# E.g. io_dad_ignore = $F[1] == 0 ignores dad0.
# All fields from the kstat line are in @F. Fields are separated
# by ':' or "\t". $F[0] is the module name, e.g. 'dad'.
# $F[1] is the instance number. $F[2] is the device name , e.g.
# 'dad0'.
#
# Magic markers (optional - used by munin-config and some installation
# scripts):
