Balloon Target
Amount of memory that can be used by memory control.
This is the target value for the virtual machine’s Memory Balloon
value, as determined by the VMkernel. The VMkernel sets a target
for the level of ballooned memory for each virtual machine, based
on a number of factors.
If Memory Balloon Target is greater than Memory Balloon, the
VMkernel inflates the balloon, causing more virtual machine
memory to be reclaimed and Memory Balloon to increase.
If Memory Balloon Target is less than Memory Balloon, the
VMkernel deflates the balloon, allowing the virtual machine to
map/consume additional memory if it needs it. Memory Balloon
decreases as the VMkernel deflates the balloon.

zero Memory Zero Amount of memory that is zeroed out (contains only 0s). This
statistic is included in Memory Shared.
VM
Amount of guest physical zero memory that
is shared through transparent page sharing.
Zero memory is simply memory that is all
zeroes.

Sum of Memory Zero of all powered on
VMs and vSphere services on the host.

Network Metrics
The network metric group tracks network utilization for both physical and virtual NICs (network interface
controllers) and other network devices, such as the virtual switches (vSwitch), that support connectivity among
all vSphere components (virtual machines, VMkernel, host, and so on).
Table C-6 lists the network data counters.
