performance counter

%IDLE
Percentage of time the resource pool, VM, or world was idle. Subtract this percentage from %WAIT to see the percentage of time the resource pool, VM, or world was waiting for some event. The difference, %WAIT- %IDLE, of the vCPU worlds can be used to estimate guest I/O wait time.

%RDY
Percentage of time the resource pool, VM, or world was ready to run, but was not be provided CPU resources on which to execute.

%RUN
Percentage of total time scheduled. This time does not account for hyperthreading and system time. On a hyperthreading enabled server, the %RUN can be twice as large as %USED. [%USED = %RUN + %SYS – %OVRLP]

%WAIT
Percentage of time the resource pool, VM, or world spent in the blocked or busy wait state. This percentage includes the percentage of time the resource pool, VM, or world was idle. [100% = %RUN + %RDY + %CSTP + %WAIT]

%CSTP
Percentage of time a resource pool spends in a ready, co-deschedule state.
NOTE You might see this statistic displayed, but it is intended for VMware use only.

[100% = %RUN + %RDY + %CSTP + %WAIT]
