Barracuda CloudGen WAN offers multiple audit and reporting functionalities to help you monitor activities throughout your network.
Audit Log
The Audit Log contains all administrative actions and displays the user and the public IP address of the user who performs an action. It can be accessed in the AUDIT LOG tab of the Cloud UI https://cloudgenwan.barracudanetworks.com/. Actions performed directly on the Local Web UI are logged with the username root. You can also download the entries as a CSV file.
Log Files
The Barracuda CloudGen WAN appliances generate log files for the following system processes:
- FW Activity Log
- Threag Log
- Web Log
- SD-WAN Log
Log files are stored and are accessible directly on the appliance. To limit the size of a single log file, the appliance creates a new log file for each service every four hours. All log files are stored in plain text in the system's /var/phion/logs directory. You can easily stream your log files to Microsoft Azure and analyze them there. For more information, see How to Configure Log Streaming to Microsoft Azure Log Analytics Workspace .

Log file entries are divided into the following segments:
- Time – The time when an event has taken place. This indicator marks individual log entries.
