How to calculate out CPU usage (%) of a VM machine?
The usage of a resource (CPU, memory, or disk) is defined as A/B, where A is the used (or in use) amount, and B the total capacity of allocation. To calculate out A/B, just find out the information for A and B from on vCenter/vSphere client. So question is which tabs, metrics or counters on vCenter are corresponding to A and B?
