Hello, colleagues.

After upgrading Splunk Stream 8.1.5 stopped parsing bytes_in, bytes_out, packets_in, packets_out, they are always equal to zero...

I am using an independent streamforwarder with streamfwd installed as a service on linux ubuntu 22.04.5
If I stop the service and replace the streamfwd file with the old version 8.1.3 and start the service again, everything is ok

Anybody run into this? 

Thanks!
