GPU
===

The GPU plugin is **only** compatible with NVIDIA GPU. You also need to
install the Python `pynvml`_ library on our system.

The GPU stats are shown as a percentage or value and for the configured
refresh time. The total GPU usage is displayed on the first line, the
memory consumption on the second one.

If you click on the ``6`` short key, the per GPU view is displayed:

Note: you can also start Glances with the --meangpu option to display the
first view by default.

You can change the thresolds limits in the configuration file:

.. code-block:: ini

      [gpu]
      # Default processor values if not defined: 50/70/90
      proc_careful=50
      proc_warning=70
      proc_critical=90
      # Default memory values if not defined: 50/70/90
      mem_careful=50
      mem_warning=70
      mem_critical=90

Legend:
