Assume i have created two VMs in a given network -- they have private ips such as 192.168.1.3 and 192.168.1.4 and I have associated floating IPs for each lets say 10.20.209.4 and 10.20.209.5. There is a network traffic thats coming outside network to both the floating IPs. Since the MAC is the same for both internal IP and the floating IP. if I collect the network.incoming.bytes meter statistics.. Does it consider both private as well as public network. if yes how to differntiate whats the traffic that went out of the VM and also whats the traffic that came from outside.. how to determine this using ceilometer.
