The 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.

Important: 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.

Understand column data

The default view of each report contains a grid with the following columns:

    • (Report Options). Jump to a detailed dashboard or control panel for:
  • Device. Device hostname, IP address, or custom label.
  • Interface. Textual name of the interface (ifName).
  • % Tx Avg. Fraction of the interface bandwidth needed for transmitted bytes.
  • % Rx Avg. Fraction of bandwidth utilized by received bytes.
  • Last Poll. Duration since last sample.

To display additional measurements, click a column heading ( ) for column selection ( ). You can also include:

  • Tx Avg. Average of available bandwidth needed for transmit.
  • Rx Avg. Average of available bandwidth needed for received traffic.
  • Tx Speed. Displays observed transmit speed for a point in time if you selected Last Polled. Displays average transmit speed if you selected a range of time (for example, Today).
  • Rx Speed. Displays observed receive speed for a point in time if you selected Last Polled. Displays average receive speed if you selected a range of time (for example, Today).
  • Tx Bytes. Byte count transmitted for the specified period.
  • Rx Bytes. 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.

Generate a report

Choose Device. Choose one or more host devices.

Choose time constraints. (,) Choose times. (For recently observed measurements, select Last Polled from the Date Range drop down list.)

Filter and reduce by row and by column. Sort and remove columns, group rows based on specific column values, and remove unwanted information from the table.

Chart, adjust output, and visualize. Fine tune report presentation and range of values displayed using the Report Settings dialog (optional).

Note: 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 Expand () from the Dashboard Options () menu. After the report has been expanded, select the Export Data icon to access the following options:

  • HTML. Generate and download a .htm file presenting your report data as it appears in the WhatsUp Gold user interface.
  • Excel. Generate and download a .xml spreadsheet containing your report data.
  • CSV. Generate and download a .csv file containing your report data.
  • Text. Generate and download a .txt file containing your report data.
  • Schedule Export. Set a recurring date and time, format, and email destination for report data export.
