What is NetFlow?
NetFlow is a technology developed by Cisco Systems that is also supported by many other hardware vendors. NetFlow is far easier to setup and use than other network traffic monitoring technologies that require the deployment of distributed hardware probes. Basically, the router or switch is setup to summarize every conversation incoming on each network interface and forwards it on to a collector, like Scrutinizer, where the details are compiled and displayed in an easy to understand format that allows IT professionals to analyze the behavior of their network.
