Hi,
As i know, MRTG can only monitor the traffic via device interface. Is there any hardware or software could use to monitor traffic via IP Address?

If your hardware supports NetFlow you could use that functionality.
In case the hardware not supported?
What exactly do you want to monitor? On the host? (Iptraf, slurm, iftop, vnstat.. munin) On the switch? (mrtg, cacti, observium - via SNMP) On a software-based firewall? (iptables rules, iptables -nvL + scripting etc) On a router/switch that supports netflow?
Just monitor traffic usage per ip-address says nothing.

There are a number of flow exporters out there ntop is a complete package. It can work of a span port to your uplink or on each server exporting to a central flow reporter. This can be CPU intensive once you get past the 100mbs line.
