Table 7‑7. Memory Panel Statistics (Continued)
Field Description
PSHARE (MB) Displays the ESXi page-sharing statistics. All numbers are in megabytes.
shared
Amount of the physical memory that is being shared.
common
Amount of the machine memory that is common across worlds.
saving
Amount of the machine memory that is saved because of page
sharing.
shared = common + saving
SWAP (MB) Displays the ESXi swap usage statistics. All numbers are in megabytes.
curr
Current swap usage.
rclmtgt
Where the ESXi system expects the reclaimed memory to be.
Memory can be reclaimed by swapping or compression.
r/s
Rate at which the memory is swapped in by the ESXi system
from disk.
w/s
Rate at which the memory is swapped to disk by the ESXi
system.
ZIP (MB) Displays the ESXi memory compression statistics. All numbers are in megabytes.
zipped
Total compressed physical memory.
saved
Saved memory by compression.
MEMCTL (MB) Displays the memory balloon statistics. All numbers are in megabytes.
curr
Total amount of the physical memory reclaimed using the
vmmemctl module.
target
Total amount of physical memory the ESXi host aempts to
reclaim using the vmmemctl module.
max
Maximum amount of the physical memory the 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 (-) appears.
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. The values are
the same for the VMM and VMX groups.
MEMSZ = GRANT + MCTLSZ + SWCUR + "never touched"
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. The values are the same
for the VMM and VMX groups.
