Interface Utilization
Interface Utilization reports reveal measurements for network traffic across one or more network interfaces for each device or device group you specify. These reports help you to visualize current and historic flow of network traffic.
If you specify a device group, the report reveals average rate and total volume of traffic for each device within the group. If you specify a switch, this report returns average rate and traffic volume across each LAN segment —a subscript (n) follows the device name to denote the port number.
: Capacity utilization figures are typically calculated using an interface speed value returned from the device. For cases where the "nominal" speed (actual operational speed adjusted for other factors such as available bandwidth) for the interface is different than the value reported back from the device, you can edit this value from the Monitors tab in Device Properties (
). For more information, see the Interface Utilization monitor topic.
(Report Options). Jump to a detailed dashboard or control panel for:- . Device hostname, IP address, or custom label.
- . Textual name of the interface (ifName).
- . Fraction of the interface bandwidth needed for transmitted bytes.
- . Fraction of bandwidth utilized by received bytes.
- . Duration since last sample.
To display additional measurements, click a column heading (
) for column selection (
). You can also include:
- . Average of available bandwidth needed for transmit.
- . Average of available bandwidth needed for received traffic.
- . Displays observed transmit speed for a point in time if you selected .Displays average transmit speed if you selected a range of time (for example, ).
- . Displays observed receive speed for a point in time if you selected .Displays average receive speed if you selected a range of time (for example, ).
- . Byte count transmitted for the specified period.
- . Byte count received for the specified period.
If a single device is selected for display, you can access the Real-Time Performance Monitor by clicking the 
icon or the Traffic Analysis Dashboard by clicking the 
icon.

: Trend lines represent a moving average that can be compared with line and area graphs to reveal peak and sub peak intervals, collision periods, and indicate transmission problems.
: This report only returns Interface Utilization metrics for devices that already have the appropriate WMI or SNMP credentials. For more information, see Using Credentials.
Export report data
Report data can be exported from WhatsUp Gold, reused, and distributed in multiple formats. Select (
) from the Dashboard Options (
) menu. After the report has been expanded, select the Export Data icon to access the following options:
- . Generate and download a .htm file presenting your report data as it appears in the WhatsUp Gold user interface.
- . Generate and download a .xml spreadsheet containing your report data.
- .Generate and download a .csv file containing your report data.
- Generate and download a .txt file containing your report data.
- . Set a recurring date and time, format, and email destination for report data export.
: Current report data file format options are only applicable to export schedules created using WhatsUp Gold version 2021 and later. Any report data export schedule created using an earlier version of WhatsUp Gold will still result in a .PDF output until that schedule is removed from, then recreated in the Scheduled Reports Library using the latest version of WhatsUp Gold.
