Review the serial port message log

Serial port messages can be reviewed from the Serial Port Log page.

A serial port message log is created and saved when serial port logging has been enabled and configured to use any of the following modes: Login, Remote Access, RealPort, or UDP Serial. You can view the log file from the Log column in the Serial Status page.

  1. Choose the management interface you want to use to access your device. Click a dropdown for instructions.

    1. Log in to Digi Remote Manager.

    1. Navigate to the device's dashboard.

    Log in to your device's Web UI.

    Log in to your device's Admin CLI via an SSH client, Telnet client, or terminal emulator.

  2. View the message log.

    1. In the left navigation menu, click Connections > Serial.

      On the Serial Status page, if the Log button is green, the serial port mode selected for the port supports serial port logging, and logging is enabled.

    2. Click the Log button to open the Serial Port Log page for that port. The Serial port log window displays.

      Note If the Log button is gray, the serial port mode selected for the port supports serial port logging, but logging is not enabled. If there is no Log button, the serial port mode selected for the port does not support serial port logging.

    3. Review the messages in the window.
      • Click Refresh to refresh the log display.
      • Click Download to download the serial port log to your local device. The log file is saved to the /opt/serial directory. Because this is being save to the device's memory, you should use serial logging for diagnostic purposes, rather than having it permanently enabled.
      • Click Restart to clear and restart the serial port log.

    1. At the Admin CLI prompt, to show the serial port's content and logging status:

      > system serial show port-number
Logging is active on port-number
>
    2. To save the log to your local device: 
      > system serial save port-number path
>

      If a relative path is provided, /etc/config/serial will be used as the root directory for the path and file. (Required)

      The log file is saved to the /opt/serial directory. Because this is being save to the device's memory, you should use serial logging for diagnostic purposes, rather than having it permanently enabled.

    3. To clear and restart the log:
      > system serial clear port-number
>
    4. Type exit to exit the Admin CLI.

      Depending on your device configuration, you may be presented with an Access selection menu. Type quit to disconnect from the device.
