CPU Ready VMware is a VMware metric measuring time when a vCPU is ready to run but waits for physical CPU scheduling.
Simple definition
CPU Ready VMware is a VMware metric measuring time when a vCPU is ready to run but waits for physical CPU scheduling. It belongs to the Virtualisation / Conteneurs vocabulary and is useful when reading architecture diagrams, product documentation, logs, or administration procedures.
What is it used for?
Its main purpose is to identify host CPU contention or vCPU oversizing of a virtual machine. The practical value depends on the surrounding architecture, security model, and operational requirements.
How does it work?
ESXi places ready vCPUs into scheduler queues. Ready time rises when physical resources are heavily contended or placement is unfavorable.
Key points
- Scope: A VMware metric measuring time when a vCPU is ready to run but waits for physical CPU scheduling.
- Operational goal: Identify host CPU contention or vCPU oversizing of a virtual machine.
- Implementation: ESXi places ready vCPUs into scheduler queues. Ready time rises when physical resources are heavily contended or placement is unfavorable.
Points to watch
Interpret the metric over a consistent interval with CPU frequency, limits, shares, and co-stop; an isolated percentage can mislead.
In short
CPU Ready VMware = a VMware metric measuring time when a vCPU is ready to run but waits for physical CPU scheduling. Use it when you need to identify host CPU contention or vCPU oversizing of a virtual machine.
