GPU
===

The GPU plugin is **only** compatible with ``NVIDIA`` GPUs.

.. note::
    You need to install the `nvidia-ml-py`_ library on your system.

The GPU stats are shown as a percentage of 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 threshold 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:
