Not sure these are related - just trying to understand the console output showing netmap_transit messages (see first screenshot) and the lack of data in netflow cache (see screenshot #2) showing ksocket_netflow_vtnetX for various node devices - yet showing no pkts or data ?!?
I've searched around but not found any decent references - any hints welcome!

OPNSense > Netflow > external destination, Telegraf on a device with inputs.netflow configured-- output is Influxdb, but I do not see *any* data, data, in the bucket.
The bucket is being written to, but that is only Netflow type of stuff?
Not exactly what I am after (I want to have the same in influxdb visualized in Grafana), but there is no metadata coming in. I am very puzzled. It throws an error in the beginning, missing template-- but that stop after a while.
However, there is no actual metadata flowing in.
