Netflow not supported?

[francescouk (Francesco Ferrari)]

HI there, I´m trying to setup netflow using filebeat and the only thing I can see is this message:

filebeat[2804]: 2021-08-24T18:10:01.108-0300        WARN        [netflow]        netflow/input.go:242        Error parsing NetFlow packet of length 849 from X.X.X.X:40102: netflow protocol version 15416 not supported

Follow my netflow.conf:

- module: netflow
  log:
    enabled: true
    var:
      netflow_host: 0.0.0.0
      netflow_port: 2055

There´s any extra configuration to be made??

Thanks for the attention.

I think the protocol you are trying to use is unsupported. See the docs:

This input supports NetFlow versions 1, 5, 6, 7, 8 and 9, as well as IPFIX. For NetFlow versions older than 9, fields are mapped automatically to NetFlow v9.
