Is flow-accounting working in any version?

Can someone tell me of a version of VyOS where flow-accounting is working? I’ve chased this all night with 1.3.2 and also the latest rolling release and I can’t find anything that works.

Try 1.4 sFlow
It is easy to use.

Does sFlow work to send data to UISP ?

It sends sflow data to sflow server

That’s not going to work then for what I want to do.
