SQUID: How to count all traffic and make a report?

Question

Squid

I recently read this article, and immediately wanted to do something similar to myself. But the question arose: is it possible, in addition to everything that is described, to somehow "fasten" the ability to collect statistics on all traffic? I mean not only on ports 80 and 443 (which go through SQUID), but on all. Because as far as I understand, if a certain Vasya starts downloading torrents, I won’t see it and it won’t be reflected in the report. Perhaps there are some crutches, or a universal combine like pfSense, but for my needs? Do not tell me?
PS still it is necessary that OpenVPN worked on the same server where there will be a squid. But OpenVPN is already a secondary task.

Answer 1

Squid will not count all traffic. Use third-party software packages, there are quite a few of them
