Is multi-GPU supported?

The server has 8 GPU graphics cards, and I need to showcase all of them.

Yep, the GPU UUID is a label in the exported metrics.

The Grafana dashboard supports switching between the GPUs, but it is able to display only a single GPU stats at a time.
If you need a dashboard which shows all GPUs at once, you could easily create it from the available metrics, and by using the current dashboard as an example.
