This article describes how to interact with Cradlepoint router logs.

The Logs allow you to track router activity, process failures, firewall events, connects and disconnects of WAN devices, DDNS (Dynamic DNS) updates, VPN connection statuses, and many other events taking place in your router. Logs are a very useful tool in troubleshooting and monitoring your router’s health at any given time.

There are several options available within the System Logs interface that can be very helpful for doing real-time troubleshooting.

  • Auto Update: This option will automatically refresh the log and display router events immediately as they occur. This option disables the normal Update.
  • Update: Clicking this button will update the log with any new router events that occurred since the System Logs page was first loaded or last refreshed.
  • Clear Log: Clear all entries in the log.
  • Search Filter: If you're searching for specific information, such as an authentication attempt, you can type in a keyword into this field.
  • Level: This drop down allows the user to view log entries of only certain levels, such as Info, Warning, Error and Critical.

Cradlepoint routers also have several built-in options to change the logging behavior.

  • Step 1: To change system log settings, click on the SYSTEM tab, select Administration, and choose System Logging.

  • Step 2: Adjust the settings as necessary and click the Apply button to save changes.

    • Logging Level: This option is used to increase or decrease the number of events that are logged by the router based on their priority. Please note: using Warning, Error, and Critical levels will permanently discard Info-level log entries.
    • Enable Logging to a Syslog Server: Send a copy of the router log to an external server. Please see this article for a detailed explanation.
    • Log to attached USB stick: Concurrently save a copy of the system log onto a USB flash drive plugged into the router. Please see this article for a detailed explanation.
    • Verbose modem logging: This option is used for intense troubleshooting. DO NOT enable it unless instructed by a Cradlepoint technical support representative.
    • Create support log: This option will generate a .txt copy of the system log, along with pertinent system information.
