Table C-5. Memory Data Counters
Counter Label Description
Entity
V H R C
active Memory Active Amount of memory actively used, as estimated by VMkernel.
Active memory is based on the current workload of the virtual
machine or host.
VM
Amount of guest physical memory in use by
the virtual machine. Active memory is
estimated by VMkernel statistical sampling
and represents the actual amount of
memory the virtual machine needs.
Host
Sum of the active guest physical memory of
all powered on virtual machines on the
host, plus memory used by basic VMKernel
applications on the host.

consumed Memory
Consumed
VM
Amount of guest physical memory
consumed by the virtual machine for guest
memory. Consumed memory does not
include overhead memory. It includes
shared memory and memory that might be
reserved, but not actually used. It does not
include overhead memory.
vm consumed memory = memory granted -
memory saved due to memory sharing
Host
Amount of machine memory used on the
host. Consumed memory includes memory
used by virtual machines, the service
console, VMkernel, and vSphere services,
plus the total consumed memory for all
running virtual machines.
host consumed memory = total host
memory - free host memory
Cluster
Amount of host machine memory used by
all powered on virtual machines in the
cluster. A cluster's consumed memory
consists of virtual machine consumed
memory and overhead memory. It does not
include host-specific overhead memory,
such as memory used by the service console
or VMkernel.
