How to Troubleshoot High CPU utliization on the Ruckus vSZ-D virtual machine
We are currently running our environment in two virtual machines: Ruckus vSZ-E and vSZ-D
According to the webUI we're running the following:
Controller Version 188.8.131.52.296
Control Plane Software Version 184.108.40.206.205
AP Firmware Version 220.127.116.11.419
We have a total of 10 x R720 and R610 APs in 1 zone with 3 AP Groups. Not a large deployment. Our subject matter expert left the company recently and I'm trying to walk through the training/documentation to become familiar with Ruckus.
Recently we've started experiencing our vSZ-D instance running at 98% CPU for long periods of time. I'm at a loss on where to begin troubleshooting this. I am able to SSH to the device and login/enable.
I've tried a few things on various posts and the tried and true graceful shutdown/restart. Could someone point me to a KB article or troubleshooting steps to start digging deeper?
