Couple of diff ways to go about this. I use Cacti and monitor throughput via SNMP for the dom0. I also enable SNMP on my switch and monitor throughput of individual ports. However if you want granularity like monitoring at the network layer (IP or layer 3), then you can look at the netflow like plugin (flow- tools and flow-scan) for Cacti and monitor actual traffic patterns of individual hosts. Or get a netflow or sflow collector in general depending on what your switch supports and enable netflow/sflow just on those ports of interest, like the one your dom0 is on.
