Issue: Ray Dashboard Links to Grafana Return "Dashboard Not Found" (Windows)

[Fatima-khanjar]

Hi all,

I'm running Ray on Windows, and I’ve successfully set up:

• Ray (ray start --head --metrics-export-port=8080)
• Prometheus, which works at http://localhost:9090
• Grafana, accessible at http://localhost:3000
• I also imported the default_dashboard.json manually from:
  C:\Users\<my_user>\AppData\Local\Temp\ray\session_latest\metrics\grafana\default_dashboard.json

What’s working:
The Ray dashboard loads fine at http://localhost:8265
Prometheus is running and collecting metrics
Grafana loads and displays plots after manually importing the dashboard JSON

The issue:
When I go to the Ray Dashboard, then click on "View metrics in Grafana", it opens Grafana but says "Dashboard not found"

The problem:
From the Ray dashboard, when I click "View metrics in Grafana", Grafana opens but shows:
Dashboard not found
So the built-in Ray → Grafana link is broken, or the dashboard is not auto-registered.

My question:
How can I fix the broken Grafana link from the Ray dashboard?

Thanks in advance!

what ray version are you using, and is there any ray version where this did previously work?

You can give it a try https://docs.ray.io/en/master/cluster/kubernetes/k8s-ecosystem/prometheus-grafana.html.

I’m currently using Ray 2.4.1. I initially tried installing a newer version on Windows, but encountered compatibility issues, so I downgraded to 2.4.1 to ensure stability.
