In the vSphere client performance tab of a virtual machine you can monitor the CPU Wait time, but it’s counted for every vCPU and no percentage metric is provided. vCenter Operations can solve that problem for you.
vCenter Operations provides different widgets to display the data collected from vCenter, storage systems or other data sources. Using the example of finding out which of the VMs in a vCenter are affected by high cpu ready % values i show you how to use heatmaps, metric graphs and data distribution widgets.
