Table A-4. CPU Panel Statistics (Continued)
Line Description
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
ESX/ESXi VMkernel, the time spent appears as %OVRLP for virtual machine A and %SYS for virtual
machine B.
%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.
%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).
You can change the display using single-key commands as discussed in Table A-5 .
Table A-5. CPU Panel Single-Key Commands
Command Description
e Toggles whether CPU statistics are displayed expanded or unexpanded.
The expanded display includes CPU resource utilization statistics broken down by individual worlds
belonging to a resource pool or virtual machine. All percentages for the individual worlds are percentage
of a single physical CPU.
Consider these examples:
n If the %Used by a resource pool is 30% on a two-way server, the resource pool is utilizing 30 percent
of two physical CPUs.
n If the %Used by a world belonging to a resource pool is 30 percent on a two-way server, that world
is utilizing 30% of one physical CPU.
U Sorts resource pools, virtual machines, and worlds by the resource pool’s or virtual machine’s %Used
column.
R Sorts resource pools, virtual machines, and worlds by the resource pool’s or virtual machine’s %RDY
column.
N Sorts resource pools, virtual machines, and worlds by the GID column. This is the default sort order.
V Displays virtual machine instances only.
L Changes the displayed length of the NAME column.
Memory Panel
The Memory panel displays server-wide and group memory utilization statistics. As on the CPU panel, groups
correspond to resource pools, running virtual machines, or other worlds that are consuming memory.
The first line, found at the top of the Memory panel displays the current time, time since last reboot, number
of currently running worlds, and memory overcommitment averages. The memory overcommitment averages
over the past 1, 5, and 15 minutes appear. Memory overcommitment of 1.00 means a memory overcommit of
100 percent. See “Memory Overcommitment,” on page 26.
