vSphere Basic System Administration Table C-2. CPU Data Counters Counter Label Description VHRC cpuentitlement guaranteed idle ready reservedCapacity Worst Case Allocation (virtual machine Resource Allocation tab) CPU Guaranteed CPU Idle CPU Ready CPU Reserved Capacity 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. n Stats Type: absolute n Unit: megaHertz n Rollup Type: latest n Collection Level: 1 n VC/ESX: No/Yes 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. n Stats Type: delta n Unit: millisecond n Rollup Type: latest n Collection Level: 3 n VC/ESX: Yes/No 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. n Stats Type: delta n Unit: millisecond n Rollup Type: summation n Collection Level: 2 n VC/ESX: Yes/Yes 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. n Stats Type: delta n Unit: millisecond n Rollup Type: summation n Collection Level: 3 n VC/ESX: Yes/Yes Total CPU capacity reserved by the virtual machines. n Stats Type: absolute n Unit: megaHertz n Rollup Type: average n Collection Level: 2 n VC/ESX: Yes/Yes •ο•ο 328 VMware, Inc.
