Measures reported by CisWLCCPUUseTest

A wireless LAN controller (WLC) is a network component that manages wireless network access points and allows wireless devices to connect to the network.

Often excess traffic to a WLAN Controller can impose a prohibitive load on the controller, choking the CPU. To proactively avoid such bottlenecks, you have to constantly monitor the CPU utilization of the target wireless LAN controller. This is where the CisWLCCPUUseTest helps. This test tracks the CPU usage of the target WLAN controller over time, and alerts you to potential CPU contentions. The test also reports the current CPU utilization of the controller, so that sudden spikes in CPU usage can be promptly captured.

Outputs of the test : One set of results for 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 the WLAN Controller. Percent If this measure reports an unusually high value, it could mean that CPU usage of the controller has spiked suddenly.
avgCpuUsage Indicates the average CPU utilization of the WLAN Controller. 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.
