Free netflow collector that forwards messages to a syslog server?

  pmacct is a small set of multi-purpose passive network monitoring tools [NetFlow IPFIX sFlow libpcap BGP BMP RPKI IGP Streaming Telemetry].

  

Your best bet is probably pmacct. I don't think this functionality is built-in per se, but it would be fairly easy to use syslog-ng or similar to read its output from file or stdout. It can also aggregate for you, if that's useful.

I use goflow2 to do something like this. I don't specifically use syslog itself for this, but mtail to generate the metrics.
