=head1 NAME

sensors_nvidia_ - Wildcard-plugin to monitor nVidia graphics card sensors

=head1 CONFIGURATION

Example configuration follows.  Only the first stanza is needed:

  [sensors_nvidia_*]
    env.nvidiasmi /usr/bin/nvidia-smi

  [sensors_nvidia_temp]
    env.nvidiasmi /usr/bin/nvidia-smi

  [sensors_nvidia_fan]
    env.nvidiasmi /usr/bin/nvidia-smi

=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 nVidia graphics cards.

For example,

  ln -s /usr/share/munin/plugins/sensors_nvidia_ \
        /etc/munin/plugins/sensors_nvidia_temp

will monitor the temperature of the graphics cards

  ln -s /usr/share/munin/plugins/sensors_nvidia_ \
        /etc/munin/plugins/sensors_nvidia_fan

will monitor the fans of the graphics cards
