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.

Stats Type: delta

Unit: millisecond

Rollup Type: summation

Collection Level: 3

VC/ESX: Yes/Yes

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

Stats Type: rate

Unit: megaHertz

Rollup Type: average
