+1 - I just crashed my spreadsheet trying to open one .tsv file. But great
news indeed Erik - this is an important first step!

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.
