vSphere Basic System Administration Table C-5. Memory Data Counters (Continued) Counter Label Description Entity VHR C vmmemctltarget zero Memory Balloon Target Memory Zero Amount of memory that can be used by memory control. •ο ο ο 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. n Stats Type: absolute n Unit: kiloBytes n Rollup Type: average (min/max) n Collection Level: 2(4) Amount of memory that is zeroed out (contains only 0s). This statistic is included in Memory Shared. ••ο ο VM Host 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. n Stats Type: absolute n Unit: kiloBytes n Rollup Type: average (min/max) n Collection Level: 2(4) 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. Table C-6.
