IOPS (I/O per Second): The total amount of I/O write operations generated by the protected virtual machines comprising the Virtual Protection Group (VPG)

Throughput (MB per Second): The total amount of uncompressed data written by the protected virtual machines comprising the Virtual Protection Group (VPG).

During synchronization processes (such as bitmap sync, initial sync and delta sync) this value will also consist of the uncompressed data read from the protected disks.

Network – The amount of WAN traffic.

Provisioned Storage (not shown by default) – The provisioned storage for all the virtual machines in the VPG. This value is the sum of the values that are used in the vSphere Client console per virtual machine in the Virtual Machines tab for the root vCenter Server node. Each value is the sum of both the hard disk and memory. Thus, a virtual machine with 1GB hard disk and 4GB memory will show 5GB provisioned storage.

Used Storage – The storage used by all of the virtual machines in the VPG. This value is the sum of the values that are used in the vSphere Client console per virtual machine in the Virtual Machines tab for the root vCenter Server node.
