I am redirecting authorized, blocked and warning logs to a GrayLog server and there doing some log analyses.This works well as now I'm able to monitor accessed websites etc. To move forward, I would need to have an idea of the bandwidth used per IP / website. Which log should be enabled for this. For example, my final goal is to monitor how many MBs / GBs an user was exchanging (upload / download) with Facebook for example. Or, how much content someone downloaded from Torrent, etc. Looking forward to hearing from you.
