### What did you do?

Configure the nvidia-gpu integration to scrape metrics from our nvidia-gpu-operator service.
This results, because its a K8s service that acts as a loadbalancer of course, we only get metrics from the randomized GPU worker nodes.

### What did you see?

metrics from randomized GPUs (5 instead of 8 worker nodes currently)

### What did you expect to see?

Metrics from all GPU servers and not only from a randomized pattern
