Documentation forNetFlow Traffic Analyzer
Analyzing network traffic and bandwidth is a key capability of Hybrid Cloud Observability Advanced and is also available in a standalone module, NetFlow Traffic Analyzer (NTA). Hybrid Cloud Observability Advanced and NTA are built on the self-hosted SolarWinds Platform.

Top XX Transmitters (Classic Chart)

This widget provides a list of the XX transmitters consuming the bandwidth over your monitored network. Transmitters are listed with the amount of data transferred, in both bytes and packets.

When placed on the Node Details or Interface Details view, this widget provides a view of the transmitters responsible for the most traffic passing through the viewed node or interface over the selected period of time.

View more details about listed transmitters

Click a transmitter endpoint to open the NetFlow Transmitters Summary View.

Click + to expand a listed endpoint and display a list of the nodes and their respective interfaces over which data are currently being transmitted by the endpoint.

Click a node or an interface to display the appropriate transmitter traffic related to the selected node or interview. For more information, see NetFlow Endpoint View.

Top XX Transmitters (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 Transmitters widget provides a ranked list of transmitters that initiated traffic to the selected node or interface.

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
Hostname Displays the name or IP address of the transmitting endpoint.
Ingress Bytes, Egress Bytes
Ingress Packets, Egress Packets
Displays the amount of data, in both bytes and packets, routed through the viewed object transmitted by the listed endpoint over the specified 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 routed through the viewed node or interface that is transmitted by the listed endpoint over the specified period of time.

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.
