Using Enterprise Overview › Interface Utilization List

Interface Utilization List

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

The Interface Utilization view is similar to the Interfaces Over Threshold view on the CA Performance Center Infrastructure Overview page.

Interface Utilization Data

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

Status

Indicates utilization level: Green (Normal), Orange (Warning or Elevated), Red (Critical).

Interface

Identifies the interface by name.

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

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

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

A description of 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.
