Network Traffic Overview dashboard

Network traffic overview dashboard provides comprehensive bandwidth analysis and performance metrics monitoring capabilities by monitoring the worst performing interfaces. This helps you to understand further the interface utilization trend and also the IP traffic composition that is related to that interface based on the flow data collected.

Use Network Traffic Overview dashboard to monitor network performance details of a particular interface, the traffic trends, and the usage patterns of your network. It identifies the network Top Talkers on applications that use the most network bandwidth.

Available widgets and their interactivity

The master-listener and drill-down widget interactions can be seen in the following ways:

For any widgets with the () drill-down icon, from the chart, click any bar that represents the interface or metric to open the drill-down dashboard page, which contains the associated widgets.
For the other widgets that are shown in the diagram to be in a master-listener or drill-down interaction, click any of the bars that represent the interface to change the listener widget that displays the related data for the selected interface.

The diagram shows the master-listener, and drill-down interactions between the available widgets:

Network Traffic Overview

Click NetFlow > Network Traffic Overview.
The Network Traffic Overview: Top 10 Traffic dashboard loads.

This dashboard provides a view of the top 10 traffic details that are ranked in order by traffic volume.
You can filter data based on the following filters:
- Site, the list contains the locations to view the traffic levels.
- Business Hour , the list contains of Business Hour, Non-Business Hour, and both as ALL.
- Time Period, the list contains of Last Hour, and Last 24 Hours.
Note:
- You can categorize your enterprise network based on different geographical areas and sites. You can configure the sites by specifying the IP address ranges and the time period for business hours and non-business hours. To configure these properties, see Configuring site grouping.
- Refer to the conditions applied when you're using the Site and Business Hour filter options.
