I have installed vnstat 2 days ago; the site got something like 20k+ visits in this time frame.
I can read a rx value of 2.16Gb but a tx value of 61.2Gb. Feels like something's going wrong. How should I interpret this ? Where could such a large amount of data com from ? (images hotlinking maybe, served images for sure, but still it is much more than what I could think of)
