In cases where flow data generation is high, or where sources are geographically dispersed, the collector function can be run on separate and geographically-distributed servers (such as rackmount server appliances). NetFlow Collector and Netflow Analyzer applications are two functions of a NetFlow analysis system or product. In some cases, the NetFlow analysis product implements both functions on the same server. This is appropriate when the volume of flow data being generated by exporters is relatively low and localized.
Synchronizing flow data to the NetFlow Analyzer application running on a separate computing resource. Storing resulting data in flat files or SQL database. Performing data volume reduction through selective filtering and aggregation. Unpacking binary flow data into text/numeric formats. Ingesting flow UDP datagrams from one or more NetFlow-enabled devices. #CISCO NETFLOW OPEN SOURCE COLLECTOR SOFTWARE#
NetFlow Analyzer: a software application that provides tabular, graphical and other tools and visualizations to enable network operators and engineers to analyze flow data for various use cases, including network performance monitoring, troubleshooting, and capacity planning.Ī NetFlow Collector’s main functions include: NetFlow Collector: an application responsible for receiving flow record packets, ingesting the data from the flow records, pre-processing and storing flow record from one or more flow exporters. NetFlow Exporter: a NetFlow-enabled router, switch, probe or host software agent that tracks key statistics and other information about IP packet flows and generates flow records that are encapsulated in UDP and sent to a flow collector. A NetFlow collector is one of three typical functional components used for NetFlow analysis: NetFlow is a protocol developed by Cisco Systems that is used to record statistical, infrastructure, routing and other information about IP traffic flows traversing a NetFlow-enabled router or switch.
