Measures reported by CisAPCPUUsTest

In a wireless local area network (WLAN), an access point is a station that transmits and receives data (sometimes referred to as a transceiver). The access point is attached to the WLAN controller (WLC) and it connects users to other users within the network and also can serve as the point of interconnection between the WLAN and a fixed wire network. In some instances, excessive CPU utilization by an access point can lead to network connectivity issues. To avoid such issues, you have to constantly monitor the CPU usage of every access point connected with the target wireless LAN controller. This is where the CisAPCPUUsTest helps. This test measures the CPU utilization of every access point, and points you to those access points that have been consistently over-utilizing CPU. The test also reports the current CPU utilization of each access point, so that sudden spikes in CPU usage can be promptly captured.

Outputs of the test :One set of results for every access point connected to the target Cisco WLAN Controller.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
currCpuUsage Indicates the current CPU utilization of this access point. Percent If this measure reports an unusually high value for an access point, it could mean that CPU usage of that access point has increased unexpectedly and inexplicably.
avgCpuUsage Indicates the average percentage of CPU utilized by this access point. Percent Ideally, the value of this measure should be low. An unusually high value or a consistent increase in this value is indicative of abnormal CPU usage which requires further investigation.
