Monitor how long per day or hour I'm close to my maximuim internet bandwith? So if it makes sense to buy an upgrade

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.
