for quite some time I'm working at home now. Recently I questioned if my current internet connection is good enough for my activity on my laptop. For some activities I notice a high internet usage, but I want clear facts and not just a gut feeling.

So I wondered, if I can automatically monitor how many seconds/minutes... per day or hour I'm close to my internet connection limit. So I can get clue if an upgrade makes sense to speed up my activity.

Is there a tool for that? I looked at vnstat, but it's not what I'm looking for. Also I would need to look at Download and Upload separately.

  • Usually for such things, your router need to support SNMP so that the counters can be extracted, compared and graphed.

  • @Bib Thank for the hint. I didn't know about this. Sadly not available at my router.

  • If it's Linux based, you may be able to gain access and install the required code.
