    Edge Security Acceleration:Instant logs

    Last Updated:Dec 01, 2025

    Instant Logs is a lightweight and easy-to-use log service that lets you view Functions and Pages logs in real time on the console. You can use the instant log data to understand how your functions are running and adjust your Functions and Pages as needed.

    Limits

    • Each function or page can have only one active monitoring window at a time. A single monitoring session can last for up to 60 minutes.

    • Instant Logs can store a maximum of 40 records. The records are sorted in reverse chronological order, and the newest records overwrite the oldest ones.

    Start monitoring

    1. Log on to the ESA console. In the navigation pane on the left, choose Edge Computing > Functions and Pages.

    2. On the Edge Routine page, click the name of the target function, or click View Details in the Actions column of the function.

    3. Choose Logs > Instant Logs > Start Monitoring to start collecting logs.

      • You can click image to view the detailed log fields for a log record.

      • You can click image in the upper-right corner to download the data in JSON format.

      • If you switch to another feature page during monitoring, the session is aborted and the history is cleared. You can click Start Monitoring again to restart instant logging.

    Stop monitoring

    1. Log on to the ESA console. In the navigation pane on the left, choose Edge Computing > Functions and Pages.

    2. On the Edge Routine page, click the name of the target function, or click View Details in the Actions column of the function.

    3. Choose Logs > Instant Logs. You can click the Stop Monitoring button, image, or image to stop the monitoring session and log collection.
