I'm trying to get netflow / insight reporting working and having an issue with data in the opnsense gui when viewing interface totals / bandwidth.
For testing I stream a UHD film and I can see the the correct/expected data in reporting / health (I think this data is not from netflow). It shows data rate of around 20Mb/s and this is what I expect from a this UHD stream.
I then use reporting / insight for interface totals and looks ok for a while then drops to zero while the film is still playing normally and reporting / health also looks normal.
I'm not sure if I am stupid or if this is a problem with my setup or a bug.
See screenshots attached.
How can I investigate further?
