SolarWinds Real-Time NetFlow Traffic Analyzer – Get it HERE. By importing netflow.v1, netflow.v5 or netflow.v9 you have direct access to the respective parsing objects, but at the beginning you probably will have more success by running the reference collector (example below) and look into its code. The analysis software is PRTG Network Monitor where the flow collector (the system with the PRTG probe) is setup as a sensor. I also wanted to play around with Cisco’s Netflow implementation. designetwork.daichi703n.com When I investigated again, I found ElastiFlow , a NetFlow collector and visualizer based on Elasticsearch + Logstash + Kibana (ELK stack). Top. As I develop this tool for my personal usage at first step, It has a small features.
