A topology view of a network is generated on a visual display of a computer system. The topology view includes subnet objects, network device objects, and interface objects within the network device objects. Network flow records are acquired from each device within the network. Separate network flow records acquired from different devices in the network are correlated together into a common network flow record. Each of the separate network flow records shares a common source address and a common destination address. The common network flow record specifies transmission path segments of a communication through the network. The common network flow is rendered in the visual display over the topology view of the network by displaying an arrow for each transmission path segment traversed by the communication through the network.
