on mirrors.wikimedia.org we provide also a mirror of tails
the tails people are asking for statistics on the number of downloads
> We wanted to ask you if it would be easy to get statistics on the number
> of downloads per binary file on your server.
>
> Some mirror operator already provide aggregate stats on the quantity of
> traffic (thanks!) but we would also be interested in being able to
> count, for example, how many ISO images are served.
>
> We're asking the same thing to all mirror operators (43) so as long as 2
> or 3 make this possible we would be able to extrapolate a grant total.
> So we're not asking you to setup something special for that or do
> complicated things but if that would be easy for you to make theses
> stats available to us then it would be amazing!
