Grafana Dashboard

HAMi ships a pre-built Grafana dashboard that visualizes GPU allocation, memory usage, and per-pod utilization metrics exported by the HAMi device plugin.

Import the Dashboard

1. Open your Grafana instance and go to Dashboards > Import.
2. Download the dashboard template:
   • gpu-dashboard.json
3. Upload the JSON file or paste its contents into the import dialog.
4. Select your Prometheus data source and click Import.

Dashboard Panels

The dashboard includes panels for:

• GPU memory allocation per pod
• GPU core utilization per pod
• Node-level GPU resource availability
• Device plugin health status

Prometheus Scrape Config

The hami-device-plugin pod on each node exposes metrics on port 31992 (configurable via devicePlugin.monitorPort). Add a scrape job:

scrape_configs:
  - job_name: hami-device-plugin
    static_configs:
      - targets:
          - <node-ip>:31992

For Prometheus Operator, create a ServiceMonitor targeting the hami-device-plugin service on port 31992.

Key metrics:

Metric	Description
hami_host_gpu_utilization_ratio	GPU real-time utilization on host (0–100)
hami_host_gpu_memory_used_bytes	GPU real-time device memory usage on host

Prerequisites

• Prometheus is installed and scraping the HAMi device plugin metrics endpoint.
• The HAMi device plugin is running and exposing metrics on the configured port.
