Table 8‑7. 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 attempts 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"
