Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

One or more vCenters, have the Workload CPU KPI in Aria Operations exceeding 100%, what does the Workload CPU metric represents and what it corresponding to in terms of calculation logic or resource utilization?

Environment

VMware Aria Operations 8.18.x

VMware vCenter Server 8.x

It represents the average active CPU load in the past five minutes.

And the 100% on VMs are expected behavior
