Amount of traffic reported is incorrect (much lower than real)

[SnapshotCiTy]

FreeBSD 14.1-RELEASE-p6
Bandwhich 0.23.1

Traffic reported by systat -if 1 is correct and matches what we see on the switch / router
Traffic reported by bandwhich is about 4x lower than what is currently being transferred /second

the traffic is a single zfs send stream through ssh

Screenshot attached.

Maybe related to #360?

On BSD-like OSes we use lsof to read system connections. I suspect this is the source of the problem, or maybe we are just using it wrong. See https://github.com/imsnif/bandwhich/blob/main/src/os/lsof_utils.rs.

Can you please try running bandwhich with --log-to and one level of --verbose? There may be some interesting logs we can take a look at.

here is the log for bandwhich running for a bit while there was some zfs send through ssh transfers under way. Hope it helps.

Yeah it seems like some source IP/host of lsof output is in an unhandled format. Although I must admit, the current logging infrastructure lacks sufficient granularity for me to fix it.

I will make some changes to error handling and logging and come back to you. Then you can either self-compile or run the CI build so that we can see what exactly the problem is.

Can you please try out #451? I realised you are on FreeBSD where we unfortunately don't have a CI build available; you would have to self-compile.

Can you please:

1. Check if the problem still persists? I found and fixed a problem during the rewrite which could explain your observations.
2. And take another log for me so I can confirm there are no other issues?

Thanks.
