Manage Clusters

The Web UI provides a page to observe what's happening with your clusters.

It also provides access to a couple of tools for interacting with and monitoring the cluster.

  • Grafana
  • Jupyter

Grafana

Click on the Grafana button to display the logs and performance metrics of your Ray cluster.

To browse the logs, click on Ray Logs -> Explore:

Here you can query Ray logs using Grafana's LogQL format. Here are a few common operation using LogQL to get you started:

  1. To filter by timerange, use the time picker in the very top row.

  1. To filter by substring, append |= "your substring" to the query.
