Hello! Seems like its complaining about the netflow.yml file. Could you try this please:
- module: netflow
log:
enabled: true
var:
netflow_host: 172.20.1.123
netflow_port: 2055
tags: [forwarded]
my guess is it doesn't like the two var.*.
If the config above works, then we can try to add the rest of the tags into the list. Thanks!
