system CPU System Amount of time spent on system processes on each virtual
CPU in the virtual machine. This is the host view of the CPU
usage, not the guest operating system view.

totalmhz CPU Total Total amount of CPU resources of all hosts in the cluster. The
maximum value is equal to the frequency of the processors
multiplied by the number of cores.
totalmhz = CPU frequency × number of cores
For example, a cluster has two hosts, each of which has four
CPUs that are 3GHz each, and one virtual machine that has
two virtual CPUs.
VM totalmhz = 2 vCPUs × 3000MHz = 6000MHz
Host totalmhz = 4 CPUs × 3000MHz = 12000MHz
Cluster totalmhz = 2 x 4 × 3000MHz = 24000MHz
