I just installed Realtime Netflow Analyzer, and configured some ASAs to send Netflow traffic to it. I can see all the SNMP level data listed, but no Flow Types are listed after an hour of running.
Doing a packet capture with Wireshark on my computer, I can see that CFLOW data and templates are arriving on port 2055, so clearly the ASAs are behaving as expected. So why am I not seeing any Flow Types?
Realtime Netflow Analyzer supports Netflow v5 only. Perhaps this could be an issue...
