Interface Utilization

The Interface Utilization view lists the interfaces throughout the enterprise that are the most heavily used. The view is a table summary of the interfaces whose utilization exceeds the user-configured thresholds. This view is located on the Enterprise Overview page.

Find Interface Utilization Information in the Performance Center Console

The Performance Center Console has a similar view, Interfaces Over Threshold. This view is located by default on the Infrastructure Overview dashboard in CA Performance Center and on the Traffic Analysis page in CA NetQoS Performance Center.

Interface Utilization Data

The Interface Utilization view displays the following information for each interface listed:

Traffic Direction

Identifies whether the reported traffic is inbound or outbound.

Speed

Lists the speed that is set for the interface by the Administrator.

Average Utilization

Lists the percentage of total utilization of the interface on average.

Percent Time Utilization Warning Level

Identifies the percentage of the time that interface utilization meets or exceeds the Warning level. The default Warning level is 50 percent utilization for 25 percent of the reporting period. The Interface Utilization list contains only the interfaces that meet the Warning level. If an operator changes this setting, the contents of the interface list may change.

Percent Time Utilization Critical Level

Identifies the percentage of the time that interface utilization meets or exceeds the Critical level. The default Critical level is 75 percent utilization of the interface capacity for 25 percent of the reporting period. The operator can change the Critical level.

Legend

Describes the criteria that determine which interfaces are displayed and what the status icons represent. In the example, the icons are defined as follows:

• Critical (red) status: The interface utilizes 75 percent or more of its bandwidth over 25 percent of the reporting period (default settings).
• Warning/Elevated (orange) status: The interface utilizes 50 percent or more of its bandwidth over 25 percent of the reporting period (default settings).

Information about changing the utilization thresholds is in Configure the Display of Interface Utilization Data.
