Chart Label Description
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

Chart Analysis
To ensure best performance, the host memory must be large enough to accommodate the active memory
of the virtual machines. The active memory can be smaller than the virtual machine memory size. It
allows you to over-provision memory, but still ensures that the virtual machine active memory is smaller
than the host memory.
