Awesome! I'm especially glad that more statistics than 'just' the
image views are included, like the aggregated views for thumbnails,
and the media files as well. I just hope somebody will built a tool
in the near future like stats.grok.se so we can view statistics for
individual files and/or sets of files a la Bagalama2.

Today WMF Analytics announces a new product: a
daily feed of media
file request counts for all Wikimedia projects [1].
The counts are based on unsampled data, so any single request
within the defined scope [2] will contribute to the counts.
It can be seen as complimentary to our page view counts files [5].
The file layout is documented on wikitech [3].
Daily counts have been backfilled from January 1, 2015 onwards.
Additionally there is a daily zip file which contains a small
subset of these raw counts: top 1000 most requested media files,
one csv file for each column [7]. As these csv files have headers
(not so easy to add in Hive) you may want to start with this file
for a first impression (best open in spreadsheet program).
The counts are collected from our Hadoop system, using a Hive
query, with data markup done in UDF scripts. This feed hopefully
addresses a long standing request, expressed often and by many,
which we regrettably couldn't fulfil earlier, as our pre-Hadoop
infrastructure and processing capacity were not up to the task.
An initial draft design (RFC) was presented last November at the
Amsterdam Hackaton 2014 (GLAM and Wikidata).
Online consultation followed, leading to the current design [4].
This is a data feed with production status, but not the final
release, as there is one major issue that hasn't been addressed yet
(but progress is being made):
When using Media viewer to view images, some images are prefetched
for better user experience, but these may never be shown to the user.
Currently,
those prefetched images are getting counted, as there is no way to
detect whether an image was actually shown to the user or not.
Gilles Dubuc and other colleagues worked on a solution that would
not hamper performance (a tough challenge) and would help us
discern viewed from non-viewed files. A few days ago a patch was
published! Adaptation of the Hive query will follow later. [6]
Also, and related, context tagging isn't supported yet. [9]
Huge thanks to all people who contributed to the process so far,
and still do.
Special thanks to Christian Aistleitner with whom I co-authored the
design, and who also wrote the Hive implementation.

[7] Before you ask: no plans yet for further aggregation into
monthly or yearly top ranking files. The current csv files are
quick wins, using standard Linux tools.
