You can add, update, or delete Netflow servers. The device offers Netflow, a network protocol, to monitor network bandwidth usage and traffic flow. Netflow records of source, destination and volume of traffic are exported to the Netflow server. The records help you identify the protocols, policies, interfaces and users consuming high bandwidth. Data analyzing tools like Open Source Data Analyzer and PRTG software can generate reports from the Netflow records.
