    Edge Security Acceleration:Instant logs

    Last Updated:Apr 01, 2025

    The instant logs feature is a real-time logging tool that collects and displays Edge Routine execution information. It offers a lightweight and user-friendly way to view logs in real time within the Edge Security Acceleration (ESA) console, helping you debug routine scripts and get execution details.

    Before you begin

    • You can have only one active monitoring session for a routine. Each session can last up to 60 minutes.

    • Instant logs can store up to 40 records at a time. The records are displayed in reverse chronological order, and newer logs overwrite older logs once the limit is reached.

    Start monitoring and view logs

    1. Log on to the ESA console, and in the left-side navigation pane, choose Edge Computing > Edge Routine.

    2. On the Edge Routine page, find the routine that you want to manage, and click the routine name or View Details in the Actions column.

    3. On the routine details page, click Logs > Instant Logs > Start Monitoring. The instant logs start to be collected.

      • Click the expand image button to view details of a log entry.

      • Click the download image button to download all the logs in JSON format.

    Stop monitoring

    1. Log on to the ESA console, and in the left-side navigation pane, choose Edge Computing > Edge Routine.

    2. On the Edge Routine page, find the routine that you want to manage, and click the routine name or View Details in the Actions column.

    3. On the routine details page, click Logs > Instant Logs.

    4. The following actions stop the monitoring:

      • Clicking Stop Monitoring. Monitoring history is kept.

      • Clicking the expand image or download image button. Monitoring history is kept.

      • Adding a filter. Monitoring history is cleared.
