Information About NBAR2 HTTP-Based Visibility Dashboard
Overview of NBAR2
HTTP-Based Visibility Dashboard
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.
