Table 7‑4. CPU Panel Statistics (Continued)
Line Description
%RDY Percentage of time the resource pool, virtual machine, or world was ready to run, but was not
provided CPU resources on which to execute.
100% = %RUN + %RDY + %CSTP + %WAIT
%MLMTD (max
limited)
Percentage of time the ESXi VMkernel deliberately did not run the resource pool, virtual machine,
or world because doing so would violate the resource pool, virtual machine, or world's limit
setting. Because the resource pool, virtual machine, or world is ready to run when it is prevented
from running in this way, the %MLMTD (max limited) time is included in %RDY time.
%SWPWT Percentage of time a resource pool or world spends waiting for the ESXi VMkernel to swap
memory. The %SWPWT (swap wait) time is included in the %WAIT time.
EVENT COUNTS/s Set of CPU statistics made up of per second event rates. These statistics are for VMware internal
use only.
CPU ALLOC Set of CPU statistics made up of the following CPU allocation configuration parameters.
AMIN Resource pool, virtual machine, or world attribute Reservation.
AMAX Resource pool, virtual machine, or world attribute Limit. A value of -1 means unlimited.
ASHRS Resource pool, virtual machine, or world attribute Shares.
SUMMARY STATS Set of CPU statistics made up of the following CPU configuration parameters and statistics. These
statistics apply only to worlds and not to virtual machines or resource pools.
AFFINITY BIT
MASK
Bit mask showing the current scheduling affinity for the world.
HTSHARING Current hyperthreading configuration.
CPU
The physical or logical processor on which the world was running when resxtop (or esxtop)
obtained this information.
HTQ Indicates whether the world is currently quarantined or not. N means no and Y means yes.
TIMER/s Timer rate for this world.
%OVRLP Percentage of system time spent during scheduling of a resource pool, virtual machine, or world
on behalf of a different resource pool, virtual machine, or world while the resource pool, virtual
machine, or world was scheduled. This time is not included in %SYS. For example, if virtual
machine A is currently being scheduled and a network packet for virtual machine B is processed
by the ESXi VMkernel, the time spent appears as %OVRLP for virtual machine A and %SYS for
virtual machine B.
%USED = %RUN + %SYS - %OVRLP
%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
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
POWER Current CPU power consumption for a resource pool (in Watts).
%LAT_C Percentage of time the resource pool or world was ready to run but was not scheduled to run
because of CPU resource contention.
%LAT_M Percentage of time the resource pool or world was ready to run but was not scheduled to run
because of memory resource contention.
