Application control monitor

The application monitor enables you to gain an insight into the applications generating traffic on your network. When monitor is enabled in an application sensor entry and the list is selected in a security policy, all the detected traffic required to populate the selected charts is logged to the SQL database on the FortiGate unit hard drive. The charts are available for display in the executive summary section of the log and report menu.

Because the application monitor relies on a SQL database, the feature is available only on FortiGate units with an internal hard drive.

While the monitor charts are similar to the top application usage dashboard widget, it offers several advantages. The widget data is stored in memory so when you restart the FortiGate unit, the data is cleared. Application monitor data is stored on the hard drive and restarting the system does not affect old monitor data.

Application monitor allows you to choose to compile data for any or all of three charts: top ten applications by bandwidth use, top ten media users by bandwidth, and top ten P2P users by bandwidth. Further, there is a chart of each type for the traffic handled by each security policy with application monitor enabled. The top application usage dashboard widget shows only the bandwidth used by the top applications since the last system restart.
