How do I check the CPU utilization on an AP?

Aruba Employee

Product and Software: This article applies to ArubaOS 3.3.2 and 3.4.0.

 

To check the CPU utilization on the access point (AP), you must have either Telnet or console access to the AP with admin access privilege.

 

On the AP console, you can either use the ‘top’ or ‘cpu -i <interval>’ command to view the CPU utilization. The interval is the sampling interval and should be 10 seconds or more to get an accurate calculation. The default interval is 10 seconds.

 

Use Control-c to terminate the program. However, when you use the ‘cpu -i <interval>’ command using Telnet, the Control-c command does not function.
