Netflow is a flow technology used for network bandwidth monitoring. Details of the traffic passing through the Security Policies can be exported as Netflow records to the Netflow Server. Based on the records received by the Netflow Server, data analyzing tools like Open Source Data Analyzer and PRTG software can generate reports.
The Netflow page displays list of configured netflow servers. The page also provides option to add, update, or delete the server.
Below are the screen elements with their description:
