How to download and interpret diagnostic logs

A diagnostic log file captures historical information about a device's operation. It is important to download the diagnostic file before rebooting or power-cycling a device as part of troubleshooting. Rebooting or power-cycling will clear the log file history.

Follow these steps to download a diagnostic file for connected devices from the WebUI: 

  1. Access the WebUI of the D621. In your browser's address bar, type:

    https://hostname

    where hostname is the hostname (KB-XX-XX-XX) or IP address of the radio. See Connecting to the AltoPlex radio for more information.

  2. Click the login link in the WebUI header to log in as administrator. The default password is admin.

  3. Click on the Admin tab.
  4. Click on the Download Diagnostic File button in the Device control section.

  5. The file is sent to your system's default download location. The file name includes the host name (KB MAC) of the device and the date. For example, KB-C7-00-01_diag_2025-11-07-20-32-26.txt
  6. Zip the file and attach it to an email to support@altowav.com or a ticket at support.altowav.com.

Create a diagnostic file from the REST API

  1. Use the admin/diagdump API to create a diagnostic file from the REST API. For example, use the curl command to save the diagnostic information to a file named diag_dump, created in the current directory: 

    curl -k -o diag_file.txt -u admin:<password> https://<hostname>/rest/v002/admin/diagdump 

    where:

    • password is the password to log into the device. The default password is admin.
    • hostname is the hostname or IP address of the device.
  2. Zip the file and attach it to an email to support@altowav.com or the ticket at support.altowav.com.
