Top XX Domains (Classic Chart)

This widget provides a view of the domains responsible for the most traffic through the viewed object over the selected period of time:

• When placed on a summary view, the widget shows top domains responsible for most traffic from all monitored nodes.
• When placed on the Node Details or Interface Details view, this widget provides a view of the domains responsible for the most traffic passing through the viewed node or interface over the selected period of time.

Notes:

• Top XX Domains widgets are not available if On Demand DNS resolution is enabled. For more information about DNS resolution options in NTA, see Configuring DNS and NetBIOS Resolution.
• Packet flow for IP groups and countries can include two domains within each communication packet processed through a network device. The total traffic presented for top domains may thus appear as much as twice what it actually is.

Top XX Domains (Endpoint Centric)

You can customize an endpoint-centric version of this widget and place it on the NetFlow Node Details or Interface Details view.

The endpoint-centric Top XX Applications widget provides a ranked list of domains to and from which the selected node or interface initiated or terminated traffic.

For more information about adding endpoint-centric widgets, see Add endpoint-centric widgets to NTA views.

Table legend

The table below the chart provides the following information:

Column Title	Contents
Domain	Displays the domain logo icon, if available, and name.
Ingress Bytes, Egress Bytes Ingress Packets, Egress Packets	Displays the amount of traffic, in both bytes and packets, transmitted by each domain through the viewed object over the selected period of time. The columns displayed depend on the flow direction set in the top left corner of the view (either only Ingress Bytes, or only Egress Bytes, or both columns).
Percent (Utilization)	Displays the percentage of all traffic over the viewed node or interface that is traceable to the listed domain. The first value describes the percentage of the appropriate item based on items shown by the chart. Individual items in the legend add up 100%. This percentage can be absolute or relative. For more information, see Set the Percentage type for Top XX lists. A value in parentheses is available only for interfaces. It describes how the appropriate item utilizes the interface bandwidth in percentage. If the utilization is approximately twice as high as it should be, for example 150% instead of 75%, it might be caused by flow duplication. For more information, see Resolve duplicate flows.
