Trigger monitoring
Written by
You can monitor triggers using the monitoring tools in your management console. These tools display diagnostic information in the form of charts. Yandex Monitoring collects metric values and displays them in charts.
The chart update period is 15 seconds.

- In the management console, go to the folder where the trigger is located.
- Open Cloud Functions.
- Select a trigger to view its monitoring charts.
- Go to the Monitoring tab.
- The following charts open on the page:
- Request latency: The average time it takes a trigger to process a request.
- Function call errors: The number of errors when calling a function or a container.
- Read events: The number of events causing a trigger to fire.
- DLQ access errors: The number of errors when accessing the Dead Letter Queue.
- Function access errors: The number of access errors when calling a function or a container.
