Table 7‑7. Memory Panel Statistics (Continued)
Field Description
CNSM Amount of the memory currently consumed by the virtual machine. The memory currently
consumed by the virtual machine is equal to the amount of memory that the VM guest
operating system currently uses, excluding the amount of memory saved for sharing if
memory sharing is enabled on the VM, excluding the amount of memory saved if some of
the VM memory is compressed. For more information on memory sharing and memory
compression, see the vSphere Resource Management documentation.
SZTGT (MB) Amount of machine memory the ESXi VMkernel wants to allocate to a resource pool or
virtual machine. The values are the same for the VMM and VMX groups.
TCHD (MB) Working set estimate for the resource pool or virtual machine. The values are the same for
the VMM and VMX groups.
%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 ESXi system attempts to reclaim from the resource pool or
virtual machine by way of ballooning.
MCTLMAX (MB) Maximum amount of physical memory the 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.
SWTGT (MB) Target where the ESXi host expects the swap usage by the resource pool or virtual machine
to be.
SWR/s (MB) Rate at which the ESXi host swaps in memory from disk for the resource pool or virtual
machine.
SWW/s (MB) Rate at which the ESXi host swaps resource pool or virtual machine memory to disk.
LLSWR/s (MB) Rate at which memory is read from the host cache. The reads and writes are attributed to
the VMM group only, LLSWAP statistics are not displayed for the VM group.
LLSWW/s (MB) Rate at which memory is written to the host cache from various sources. The reads and
writes are attributed to the VMM group only, LLSWAP statistics are not displayed for the
VM group.
CPTRD (MB) Amount of data read from checkpoint file.
CPTTGT (MB) Size of checkpoint file.
ZERO (MB) Resource pool or virtual machine physical pages that are zeroed.
SHRD (MB) Resource pool or virtual machine physical pages that are shared.
SHRDSVD (MB) Machine pages that are saved because of resource pool or virtual machine shared pages.
OVHD (MB) Current space overhead for resource pool.
OVHDMAX (MB) Maximum space overhead that might be incurred by resource pool or virtual machine.
OVHDUW (MB) Current space overhead for a user world. (You might see this statistic displayed, but it is
intended for VMware use only.)
GST_NDx (MB) Guest memory allocated for a resource pool on NUMA node x. This statistic is applicable
on NUMA systems only.
