Table C-2. CPU Data Counters
Counter Label Description V H R C
cpuentitlement Worst Case Allocation
(virtual machine
Resource Allocation
tab)
Amount of CPU resources allocated to the virtual machine
or resource pool based on the total cluster capacity and the
resource configuration (reservations, shares, and limits) on
the resource hierarchy.
cpuentitlement is computed based on an ideal scenario in
which all virtual machines are completely busy and the load
is perfectly balanced across all hosts.
This counter is for internal use only and is not useful for
performance monitoring.

guaranteed CPU Guaranteed Not supported for ESX 4.x systems, except through vCenter
Server. CPU time that is reserved for the entity. For virtual
machines, this measures CPU time that is reserved, per
virtual CPU (vCPU).
This counter has been deprecated and should not be used to
monitor performance.

idle CPU Idle Total time that the CPU spent in an idle state (meaning that
a virtual machine is not runnable). This counter represents
the variance, in milliseconds, during the interval.

ready CPU Ready Percentage of time that the virtual machine was ready, but
could not get scheduled to run on the physical CPU. CPU
ready time is dependent on the number of virtual machines
on the host and their CPU loads.
