With the NBAR HTTP-based Visibility Dashboard feature, you can have better visibility of the traffic and thereby have a good understanding of the requirement of a network.

After you enable the NBAR HTTP-based Visibility Dashboard feature on the router, a periodic task is created, which collects the NBAR discovery data per minute and stores the data in a database. This feature also provides an option to see the statistics over a defined period of time (for example, last 24 hours), which is the window size. Based on the window sizes (which are 2hr, 24hr, and 48hr window sizes), a WEB application is created, which you can access using the HTTP server utility option in the device. The Web application helps to view the NBAR data in a graphical way including interactive charts and a bandwidth graph for each window size.
