Flow Monitor: Top Senders
This workspace 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 sort traffic by bytes, packets, or flows. By default the report sorts by bytes and provides a list of the top senders by number of bytes. Sorting by packets provides information on the top senders by number of packets, while sorting by flows provides insight into the top senders by number of flows. These alternate sorting methods allow you to monitor and identify hosts that are the largest consumers of interface resources other than bandwidth.
- . Displays the hosts that are the top senders on the interface.
- . When sorting on packets, displays the number of packets sent by the host during the date range.
- . When sorting on flows, displays the number of flows created by the host during the date range.
- . Displays the bytes per second for the report category.
- . Displays the percentage of the total available bandwidth used by the report category.
: Usage is displayed as N/A if a speed is not specified for the interface. You can set this speed on the Flow Interface dialog. To navigate to the Flow Interface dialog, right-click on the interface on which you want to set the speed, then click .
. Displays the percentage ranking of the item within the top "n" items of the report category.
: You can hover over a host name to display popup information about the host name's IP address. If you right-click on the host-name, a filter will be created that uses the host as the filter criteria and the Interface Details workspace will reload with this filter applied.
: You can hover over information in the column to display popup information with average data speed as a percentage of the total interface capacity.

About interface traffic directions
: For illustration purposes, the descriptions and diagrams in the table below assume that traffic is passing from an internal interface to an external interface or vice versa. In reality, traffic may pass from an internal interface to another internal interface, an external interface to another external interface, or traffic may be routed out the same interface it enters.

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.

Linking to Flow Monitor reports from WhatsUp Gold
There are several ways to connect to the Flow Monitor Interface Details report from this WhatsUp Gold workspace report.
- Click the interface name at the top of the workspace report to view the Flow Monitor Interface Details report for the selected interface.
- Click an entry in the far left column of the workspace report to view the Interface Details report for the selected interface. The entry that you click will be applied to the report as a keyword filter.
Configuring this workspace report
