You can monitor triggers using the monitoring tools in the management console. These tools display diagnostic information as charts. Metric values are collected and charts are displayed by Monitoring.

The chart update period is 15 seconds.

Viewing monitoring charts

  2. Select Serverless Containers.

  3. Select a trigger to view its monitoring charts.

  4. Go to the Monitoring tab.

  5. The following charts will open on the page:

    • Request latency: Average time it takes a trigger to process a request.
    • Read events: Number of events that have set off a trigger.
    • Function access errors: Number of access errors when calling a container.
    • Function call errors: Number of errors when calling a container.
    • DLQ access errors: Number of errors when accessing the Dead Letter Queue.
    • Send to DLQ errors: Number of errors when sending messages to the Dead Letter Queue.

You can select the time period to display information for: hour, day, week, month, or a custom interval.
