In the past, I've used <a href="https://github.com/manuelkasper/AS-Stats" target="_blank">
AS-Stats</a> for this purpose. However, it is particularly CPU and disk IO intensive. Also, it has not been actively maintained since 2017.<br>

<a href="https://www.influxdata.com/what-are-netflow-and-sflow/" target="_blank">InfluxDB wants to sell me</a> on Telegraf + InfluxDB + Chronograf + Kapacitor, but I can't find any clear guide on what hardware I would need for that, never mind how to set up
the software. It does appear to have an open source option, however.<o:p></o:p></span></p>
