Virtual Machine CPU Usage (%) Metric in Aria Operations displays values exceeding 100%

Products

• VMware Aria Operations (formerly vRealize Operations) 8.x

Issue/Introduction

After upgrading to Aria Operations 8.18.4 or later, the Virtual Machine CPU Usage (%) Metric displays values exceeding 100%.

Environment

VMware Aria Operations 8.18.x

Resolution

This is an expected behavior.

Starting with VMware Aria Operations 8.18.4, the CPU Usage (%) metric was updated to more accurately reflect true resource demand. As a result, this metric is no longer artificially capped and can now display values greater than 100% (for example, due to host CPU Turbo Boost or ESXi kernel overhead).

Additional References: For more information on how this metric is calculated, please review the following documentation:

• Broadcom KB  Performance charts do not limit percent metrics to 100%
