=head1 NAME
|
|
|
|
nvidia_gpu_ - Wildcard plugin to monitor NVIDIA GPUs. Uses nvidia-smi utility,
|
|
usually bundled with NVIDIA GPU driver, to obtain information.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
This is a wildcard plugin. The wildcard prefix link name should be the
|
|
value to monitor.
|
|
|
|
This plugin uses the following configuration variables:
|
|
|
|
[nvidia_gpu_*]
|
|
env.smiexec - Location of nvidia-smi executable.
|
|
env.warning - Warning temperature
|
|
env.critical - Critical temperature
|
|
|
|
=head2 DEFAULT CONFIGURATION
|
|
|
|
The default configuration is to set "env.smiexec" to /usr/bin/nvidia-smi and
|
|
assume warning and critical temperatures of 75 and 95 degrees celsius, respectively.
|
|
|
|
=head2 EXAMPLE WILDCARD USAGE
|
|
|
|
C<ln -s /usr/share/munin/plugins/nvidia_gpu_ /etc/munin/plugins/nvidia_gpu_temp>
|
|
|
|
...will monitor the temperature of available GPUs.
|
|
|
|
=head1 TODO
|
|
|
|
=over 4
|
|
|
|
=item *
|
|
|
|
Add support for specific professional GPU features such as number of compute
|
|
processes, clocks, power draw, utilization, and so on.
|
|
|
|
=item *
|
|
|
|
Use multigraphs for multiple GPUs (http://munin-monitoring.org/wiki/MultigraphSampleOutput).
