# Clewarecontrol device serial must be set in config file:

#  #Put the following lines in /etc/munin/plugin-conf.d/cleware
#   [cleware*]
#   #device serial. find it by running: clewarecontrol -l
#   env.serial 7778
#   #path of clewarecontrol
#   env.bin /usr/bin/clewarecontrol
#
#  Munin must be able to read and write to the device.
#  Run the following as root:
#  # chgrp munin /dev/usb/hiddev0
#  # chmod g+rw /dev/usb/hiddev0
#
#  If that works, you have to make it permanent. On Ubuntu:
#  Create this file: /etc/udev/rules.d/99-hidraw-permissions.rules
#   #Allow munin to read hidraws from Cleware
#   SUBSYSTEM=="usb", KERNEL=="hiddev*", GROUP="munin", MODE="0660"
