Table A-6. Memory Panel Statistics (Continued)
Field Description
SWAP (MB) Displays the ESX/ESXi swap usage statistics. All numbers are in megabytes.
curr Current swap usage.
target Where the ESX/ESXi system expects the swap usage to be.
r/s Rate at which memory is swapped in by the ESX/ESXi system
from disk.
w/s Rate at which memory is swapped to disk by the ESX/ESXi
system.
MEMCTL (MB) Displays the memory balloon statistics. All numbers are in megabytes.
curr Total amount of physical memory reclaimed using the
vmmemctl
module.
target Total amount of physical memory the ESX/ESXi host attempts to
reclaim using the vmmemctl module.
max Maximum amount of physical memory the ESX/ESXi host can
reclaim using the vmmemctl module.
AMIN Memory reservation for this resource pool or virtual machine.
AMAX Memory limit for this resource pool or virtual machine. A value of -1 means Unlimited.
ASHRS Memory shares for this resource pool or virtual machine.
NHN Current home node for the resource pool or virtual machine. This statistic is applicable only
on NUMA systems. If the virtual machine has no home node, a dash (-) is displayed.
NRMEM (MB) Current amount of remote memory allocated to the virtual machine or resource pool. This
statistic is applicable only on NUMA systems.
N% L Current percentage of memory allocated to the virtual machine or resource pool that is local.
MEMSZ (MB) Amount of physical memory allocated to a resource pool or virtual machine.
GRANT (MB) Amount of guest physical memory mapped to a resource pool or virtual machine. The
consumed host machine memory is equal to GRANT - SHRDSVD.
SZTGT (MB) Amount of machine memory the ESX/ESXi VMkernel wants to allocate to a resource pool or
virtual machine.
TCHD (MB) Working set estimate for the resource pool or virtual machine.
%ACTV Percentage of guest physical memory that is being referenced by the guest. This is an
instantaneous value.
%ACTVS Percentage of guest physical memory that is being referenced by the guest. This is a slow
moving average.
%ACTVF Percentage of guest physical memory that is being referenced by the guest. This is a fast
moving average.
%ACTVN Percentage of guest physical memory that is being referenced by the guest. This is an
estimation. (You might see this statistic displayed, but it is intended for VMware use only.)
MCTL? Memory balloon driver is installed or not. N means no, Y means yes.
MCTLSZ (MB) Amount of physical memory reclaimed from the resource pool by way of ballooning.
MCTLTGT (MB) Amount of physical memory the ESX/ESXi system attempts to reclaim from the resource pool
or virtual machine by way of ballooning.
MCTLMAX (MB) Maximum amount of physical memory the ESX/ESXi system can reclaim from the resource
pool or virtual machine by way of ballooning. This maximum depends on the guest operating
system type.
SWCUR (MB) Current swap usage by this resource pool or virtual machine.
