Monitor Trino with Pulse Alerts
Pulse alerts help you monitor the health and availability of Trino services by continuously checking key metrics and triggering notifications when issues are detected.
You can:
- Enable built-in stock alerts to automatically track when the Trino Coordinator and Worker services become unreachable.
- Enable predefined alerts that run multiple queries to detect more complex issues.
- Create custom alerts in Pinot to monitor key metrics and trigger notifications when thresholds are breached. Common metrics include:
- JVM Memory Usage: Detects high memory consumption on Coordinators and Workers.
- Free Memory: Monitors low available memory to prevent crashes.
- Thread Count: Tracks JVM thread usage to identify performance bottlenecks.
- Query Failures: Flags failed or OOM (Out of Memory) queries.
- Task and Executor Stats: Monitors task execution and thread pool health.
These alerts allow you to detect failures early, respond faster to service degradation, and maintain system reliability.

Trino Stock Alerts
Pulse provides built-in (stock) alerts with preconfigured filters and conditions. You can enable, disable, or modify these alerts based on your monitoring needs. These are useful for detecting common failures like service unavailability.
| Alert Name | Description |
|---|---|
Trino Coordinator Endpoint Check | Triggered when the Trino Coordinator service becomes unreachable, indicating potential downtime or network issues. |
| Trino Worker Endpoint Check | Triggered when the Trino Worker service becomes unreachable, which may impact query processing and workload distribution. |
Trino Custom Alerts
Custom alerts let you define alert logic using Trino-specific metrics and conditions.
You can configure filters, set thresholds, and choose notification channels to monitor what matters most in your environment.
