Is there a way to get a report for historic network activity? Right now, I’ve installed sysstat and learning to use that. My search engine searching has got some results, but when I read about some programs that monitor activity, I’m not sure if I am overlooking something or if they don’t offer it or if I have combed the doc files enough so figured I’d ask here.

I’m teaching myself how to run my own server. Starting with storage needs and then seeing how it goes from there. I’m hoping to find a way to get a report of past traffic/activity specifically.

Running Debian 12.
