What are the means of monitoring traffic with a web muzzle?

Question

System administration

Actually the question is in the question. There is a server, it used to be a VPS, the hoster had a schedule of daily traffic consumption in his personal account. As if this question did not bother me, but now I can’t find anything simple so that:
- there is a schedule of incoming and outgoing traffic from the server
- the ability to select a period
- bonus: saving data
- a web interface with a login and password or binding to IP is required the address.
