Chart Label Description
Balloon Target Sum of the balloon target memory of all powered on virtual machines on the host.
If the balloon target value is greater than the balloon value, the VMkernel inflates the
balloon, causing more virtual machine memory to be reclaimed. If the balloon target
value is less than the balloon value, the VMkernel deflates the balloon, which allows
the virtual machine to consume additional memory if needed.
Virtual machines initiate memory reallocation. Therefore, it is possible to have a
balloon target value of 0 and a balloon value greater than 0.

Consumed Amount of machine memory used on the host.
Consumed memory includes virtual machine memory, service console memory, and
VMkernel memory.
consumed memory = total host memory - free host memory

Granted Sum of the guest physical memory granted for all powered on virtual machines.
Granted memory is mapped to the host's machine memory.
Granted memory for a host includes the shared memory of each virtual machine on
the host.

Shared Common Amount of machine memory shared by all powered on virtual machines.
Shared common memory consists of the entire pool of memory from which sharing
is possible, including the amount of physical RAM required by the guest memory.
memory shared - memory shared common = amount of memory saved on the host
from sharing
