We'd like to be able to track downloads of ZIM files being served to the Android Wikipedia app. This could be done client-side or server-side, whichever makes most sense technically.
Basically, we just want track requests and (ideally) completed downloads of each compilation available via the end-point. Being able to sort that by country would also be useful.
This data will be used to determine impact of offline compilations work and inform product decisions around expanding or improving this feature.
As with page-views, its also potentially as a signal or feedback channel to communities about the kind of compilations user may want them to build or improve.
