Netflow is a network traffic accounting protocol developed by Cisco Systems and currently supported by numerous vendors. To collect traffic information using Netflow, the following components are required:
-
Sensor: gathers statistics on the traffic passing through it and sends this data to the collector.
-
Collector: receives the data from the sensor and stores it.
-
Analyzer: analyzes the data gathered by the collector and forms human-readable reports (often in the form of graphs or charts).
A UserGate server can function as a sensor. To collect and send out statistics on the traffic passing through a specific UserGate network interface, follow these steps:
