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.
To display additional measurements, click a column heading () for column selection (). You can also include:
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.
Choose Device. Choose one or more host devices you want Interface Utilization measurements for.
Choose time constraints. (,) Choose times for the Interface Utilization. (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.
Most generated Interface Utilization report data can be printed, shared, and exported when selecting Expand () from the Dashboard Options () menu. After the report has been expanded, select export () to access the following options:
