What's the best GPU monitoring tool for tracking utilization across inference clusters?

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).
