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.
In the Pulse UI, navigate to the Trino Dashboard to analyze Trino's performance and system health.
