Network traffic may be logged and analyzed to perform accounting on amount of a chargeable network resource that is consumed fulfilling requests for different clients or for different servers. A network device may report network traffic to a server through NetFlow data records. The network traffic records may be generated by monitoring traffic through either the ingress ports or the egress ports of a network device. Monitoring only ingress or egress ports reduces or eliminates duplication of network traffic counting. Two-directional network traffic may be monitored by transmitting traffic in one direction through a first interface and in a second direction through a second interface. |
