Untangle's Reports is used to help administrators monitor users' behavior and understand network usage. Also, it's a great tool to help administrators investigate security incidents. Untangle provides a summary, detailed, and reports per user.
Untangle's Reports application collects the application's event logs, which contain the real-time detailed data, and provides a summary report about the event logs' activity displayed in graphs and charts. Also, the detailed event logs can be accessed from Untangle's Reports application (if they are in the retention period range).
Untangle's Reports is available in PDF and HTML formats and can be automatically e-mailed to administrators.
