Top Senders

This dashboard report shows the devices generating the most traffic traveling in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce) on the selected interface.

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.

By default, devices are listed by hostname, however you can configure this report to list the devices by IP address by selecting Display IP Address instead of Hostname on the report configuration dialog.

Sender. Displays the hosts that are the top senders on the interface.
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 appears as the first column header in the report and is 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.
Throughput. 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.
Usage. 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, click the Configure link in the message appearing above the dashboard reports.
Percentage. Displays the percentage of the total traffic for the specific item in the report category for the selected date range.
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 a host name to display popup information about the host name's IP address. If you click the host-name, a filter is created that uses the host as the filter criteria and the Interface Details dashboard reloads with this filter applied.

Tip: You can hover over the icon preceding the Senders host name to display WHOIS information about the host. This information is gathered using a WHOIS query of the American Registry for Internet Numbers (ARIN).

Interface	Traffic Direction	Report displays...
Internal interface	Inbound	The top senders among devices on the LAN segment connected to the selected internal interface that are communicating with outside devices.
	Outbound	The top senders among outside devices that are communicating with devices on the LAN segment connected to the selected internal interface.
	Inbound/ Outbound	The top senders among all devices that are transmitting traffic across the selected internal interface.
External interface	Inbound	The top senders among devices connected to the selected external interface that are communicating with devices on an internal LAN segment.
	Outbound	The top senders among devices on internal LAN segments that are communicating with devices connected to the selected external interface.
	Inbound/ Outbound	The top senders among all devices that are transmitting traffic across the selected external interface.
