Table 1‑115. Data Counters
Chart Label Description
Active 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. The value is based on the current workload of the virtual
machine.

Balloon Target Desired amount of virtual machine balloon memory.
Balloon target memory is estimated by the VMkernel.
If the balloon target amount is greater than the balloon amount, the VMkernel inflates the balloon
amount, which reclaims more virtual machine memory. If the balloon target amount is less than the
balloon amount, the VMkernel deflates the balloon, which allows the virtual machine to reallocate
memory when needed.

Consumed 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.
consumed memory = memory granted - memory saved due to memory sharing
