Visualizing GPU Metrics with DCGM Exporter
- The article introduces the process of visualizing NVIDIA GPUs' operating status using DCGM Exporter with Prometheus and Grafana.
- DCGM (Data Center GPU Manager) helps in monitoring and managing GPUs, providing metrics in Prometheus format through DCGM Exporter.
- Using DCGM Exporter eliminates limitations of manual polling and allows centralized monitoring of GPU status.
- The setup involves a GPU server with DCGM Exporter and a monitoring server with Prometheus and Grafana.
- Steps include setting up DCGM Exporter on the GPU server and launching Prometheus and Grafana on the monitoring server.
- Verification steps ensure proper installation and running of DCGM Exporter and Prometheus targets.
- Users can create Grafana dashboards to visualize GPU metrics like temperature, utilization, and memory bandwidth in real time.
- Multiple GPU servers can be managed collectively in Grafana, and essential operational aspects like alert settings and data retention are highlighted.
- References to DCGM Exporter GitHub, NVIDIA Docs, Prometheus and Grafana installation guides, and a specific Grafana dashboard template are provided for further exploration.
- The article concludes by emphasizing the flexibility of the setup for both single and multiple server environments for GPU monitoring.
