  2. Enable Screenshot Function (Optional)

    • If you want to record changes in the UI during the session, enable the “Enable Screenshot” option before starting the monitoring.
    • Screenshots will be automatically saved along with performance data in a time-series, linked to the corresponding data.

  3. Save Data
