Title: netflow on 25.7
Post by: planetf1 on July 23, 2025, 08:11:33 PM
With 25.7 I don't seem to be able to get netflow working.

- destination is set to 127.0.0.1:2056
- lan, wan are listening
- wan interface is 'wan'
- local capture is selected
- using v9
- insight aggregator/netflow distributor are running (and has been restarted)
- I've reset the rrd & netflow data

I still don't seem to get any data showing up under reporting->insight

I cannot 'telnet 127.0.0.1:2056'

I do have a large flowd.log file

Yes, I see the same after upgrading to 25.7; nothing in Reporting -> Insight at all.

It's just the Insight->Totals and Insight->Details views which are coming up blank for me.

I see that the .csv file exports from Insight do contain data for today's date.

I'm giving this a look and see if I can find anything weird going on.

+1  Tried bouncing flowd service, clearing all netflow data and restart, restored RRD data after restart, zip, nothing shows up in insight graph any more.

It was a regression accidentally caused in the camelCase to snake_case conversion.

Can somebody try:
