sensors_amd_ - Wildcard-plugin to monitor AMD graphics card sensors

=head1 CONFIGURATION

This plugin needs to be run as root for aticonfig to work.

Example configuration follows.  Only the first stanza is needed:

  [sensors_amd_*]
    user root
    env.aticonfig /usr/bin/aticonfig
    env.x11display 0
    env.xorgconf /etc/X11/xorg.conf

  [sensors_amd_temp]
    env.x11display 8
    env.xorgconf /etc/X11/xorg-fglrx.conf

  [sensors_amd_fan]
    env.x11display 8
    env.xorgconf /etc/X11/xorg-fglrx.conf

=head2 ENVIRONMENT VARIABLES

This plugin does not use environment variables.

=head2 WILDCARD PLUGIN

This is a wildcard plugin.  To monitor the temperatures or
fans of AMD graphics cards.

For example,

  ln -s /usr/share/munin/plugins/sensors_amd_ \
        /etc/munin/plugins/sensors_amd_temp

will monitor the temperature of the graphics cards

  ln -s /usr/share/munin/plugins/sensors_amd_ \
        /etc/munin/plugins/sensors_amd_fan

will monitor the fans of the graphics cards
