How to do it…

Let's get started:

1. Open up vSphere Web Client.
2. On the home screen, navigate to Hosts and Clusters.
3. Expand the left-hand navigation list.
4. Navigate to one of the CPU-hungry VMs.
5. Navigate to the Monitor tab.
6. Navigate to the Performance tab.
7. Navigate to the Advanced view.
8. Click on Chart Options.
9. Navigate to CPU from Chart metrics.
10. Navigate to the VM object and only select Demand, Ready, and Usage in MHz.

11. Click on Ok.

In the following screenshot, you will see the high ready time of the VM:

Notice the amount of CPU this VM is demanding and compare that to the amount of CPU usage the VM is actually being able to get (usage in MHz). The VM is demanding more than it is currently being allowed to use.

Notice that the VM is also seeing a large amount of ready time.
