nethogs significantly underestimating Zoom traffic

onavsaber opened this issue 4 years ago · comments

I am using nethogs on Ubuntu 20.04. I have also zoom installed. During a meeting sharing video, tools like iftop show traffic to be in the orders of 200KB/s. However, nethogs shows zoom traffic at much lower speeds, like a few KB/s. I have build the latest version of nethogs from the repository.

The same problem with google meet in the browser, show 1 KB/s where the actual speed is 50-100 KB/s

Are you sure you are looking at only TCP data? Nethogs doesn't count UDP data.

@raboof you are right. Thanks. When I include -C option, I do see reasonable traffic under "unknown UDP".
Just curious, would Nethogs be able to monitor UDP in the future?

I'm not sure we can get really reliably data for those, see #62

I'll close this for now, if you see nethogs significantly underestimating TCP traffic feel free to re-open (or open a new issue)
