Resource Pools Do Not Display CPU Usage of Virtual Machines

Products

• VMware vSphere ESXi
• VMware vCenter Server 7.0
• VMware vCenter Server 8.0

Issue/Introduction

When observing the Resource Pool Capacity and Usage in vSphere client, CPU or memory usage may show lower than expected, or have a zero value.

Environment

• vCenter Server 7.x 
• vCenter Server 8.x.

Cause

Resource pool usage will show resource reservations only. If no reservations are set on a VM in a resource pool, the current CPU and memory usage will not be displayed at the resource pool UI.

 

Resolution

You can see current resources utilization in Monitor/Utilization tab.

Set CPU reservations on VMs on a needed basis when grouped under child resource pools.
