For tracking GPU utilization across inference clusters, the “best” tool usually depends on whether you want simple fleet visibility or deep observability + alerting. In practice, the strongest choice is often:
Best overall: Prometheus + Grafana + NVIDIA DCGM Exporter
Why this is usually the best:
- Cluster-wide visibility across many nodes and GPUs
- Tracks key GPU metrics like:
- utilization
- memory usage
- temperature
- power draw
- ECC errors
- throttling
- Works well with Kubernetes and large inference fleets
- Easy to build dashboards and alerts
- Integrates cleanly with existing observability stacks
Typical setup
- DCGM Exporter on each GPU node
- Prometheus scrapes metrics
- Grafana visualizes them
- Optional: Alertmanager for alerts
Best if you want the easiest NVIDIA-native cluster monitoring: NVIDIA DCGM
If your environment is mostly NVIDIA GPUs, DCGM is the core monitoring layer.
It’s not a full visualization tool by itself, but it’s the most reliable source for GPU telemetry.
Use it when you care about:
- accurate GPU metrics
- production-grade monitoring
- low overhead
- integration into your own dashboards
Best if you want a commercial, turnkey platform
If you want less setup and more out-of-the-box cluster monitoring:
- Grafana Cloud
- Datadog
- New Relic
- Arize / Weights & Biases / Comet for ML-focused observability, though these are less GPU-infrastructure-centric
These can be great if you want:
- centralized dashboards
- alerting
- logs + traces + infra metrics in one place
For Kubernetes inference clusters specifically
A strong stack is:
- NVIDIA DCGM Exporter
- Prometheus
- Grafana
- kube-state-metrics
- optionally NVIDIA GPU Operator
This gives you both:
- GPU-level utilization
- pod/workload-level context
Quick recommendation
- Best free/open-source choice: Prometheus + Grafana + NVIDIA DCGM Exporter
- Best NVIDIA-native telemetry source: DCGM
- Best turnkey commercial option: Datadog or Grafana Cloud
If you want, I can also recommend the best tool for your specific setup (Kubernetes vs bare metal, NVIDIA vs AMD, open-source vs managed).
