• Used Memory — value which represents the amount of memory allocated to
the virtual machine when it was configured, how much memory has been used
recently by the virtual machine and how much memory has been shared
between all running virtual machines on the server and within the virtual
machine itself.
• Reclaimed Memory — value which represents how much memory has been
reclaimed by ESX Server under heavy loads or when you are overcommitting
memory.
• Virtualization Overhead — represents how much extra memory the virtual
machine process is using, in addition to the amount of memory allocated to it.
