About the Flow Monitor: Top Sender Domains report
This dashboard report displays the top domains whose devices are generating traffic that is routed over the selected interface in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce). The traffic displayed for each domain is the sum of the traffic generated by each device on that domain.
Note: The domains listed in this dashboard report are obtained from the last two parts of a host name.
Domain data is useful in determining where the persons on a network are spending the most time. If you see a domain that isn't network-friendly, you can drill down by adding a filter for the domain and detect the device or devices visiting the suspect Web location.
You can choose to display and sort sender traffic by bytes, packets, or flows using the Display and sort by option on the report configuration dialog. Providing alternate sorting methods allows you to monitor and identify hosts that are the largest consumers of interface resources other than bandwidth.
- Receiver. Displays the hosts that are the top receivers on the interface.
- Sender Domain. Displays the top sender domain.
- You can select one of the following units to display and sort the specific items in the report using the Display and sort by option on the report configuration dialog. The selected option will appear as the first column header in the report and will be used to sort the top "n" items.
- Bytes. Displays the total number of bytes transmitted for the specific item in the report category for the selected date range.
- Packets. Displays the total number of packets for the specific item in the report category for the selected date range.
- Flows. Displays the total number of flows for the specific item in the report category for the selected date range.
- Rate. Displays the average bit rate, packet rate or flow rate, in multiples of the selected unit (e.g. Kbps, Mbps, or Gbps) for the specific item in the report category for the selected date range.
- Utilization. Displays the percentage of the total available bandwidth used by the specific item in the report category for the selected date range.
Note: Utilization is displayed as N/A if a speed is not specified for the interface, or if you have selected to display packets or flows in the report. If you are displaying bytes, you can set the interface speed on the Flow Interface dialog. To navigate to the Flow Interface dialog, right-click on the interface and then click Configure > Source > Edit.
- Percentage. Displays the percentage of the total traffic for the specific item in the report category for the selected date range.
- Others (row title). The optional Others row title displays a summation of all of the unspecified items of the report category. The unspecified items are those items not specifically displayed in the top "n" items. The Others row provides a comparison between the specified items, or top "n" items selected for display, and the rest of the traffic on the interface. When displayed, the Others row will provide perspective as to the relative size of the specified items in comparison to the total traffic on the interface.
- Totals (row title). Displays the total of all of the items in the report category, specified and unspecified (Others). This row shows the interface totals for each column in the report.
Tip: You can hover over information in the Bytes column to display popup information with average data speed as a percentage of the total interface capacity.
