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
- In the Pulse UI, go to the Trino > Dashboard.
- Set a time range and step interval to view the timely information.
