Thanks LucD
Another question,, would I be right to say that if the VM is consuming a "net.usage.average" of 185 KBps in 20 minutes, then this is traffic that is flowing at the physical network adapter and not the virtual network adapter? there will be more traffic flowing at the virtual network adapter level as VM-to-VM traffic for VMs at the same physical ESXi host won't be part of this 185KBps.
Appreciate your help...
