Trino Dashboard

The Trino Dashboard page shows the following metrics in the form of dashboards and charts that monitor system health and query activity.

Key metrics include:

  • Node count for Coordinators and Workers

  • Query states (started, running, completed, failed)

  • JVM heap usage and active thread count

  • CPU time and load for Trino processes

These metrics help you track workload trends, detect performance bottlenecks, and ensure overall Trino cluster stability.


Steps

  1. In the Pulse UI, go to the Trino > Dashboard.

  2. Set a time range and step interval to view the timely information.
