Description christian 2013-12-04 14:32:33 UTC
Since CentralAuth's use of

  Special:CentralAutoLogin/start
  Special:CentralAutoLogin/createSession

(~mid July 2013) Page Views shown on wikistats are too high, as
webstatscollector counts the above requests and wikistats just sums
over requests counted by webstatscollector.

However, the above endpoints do not qualify as page view.

Comment 1 christian 2013-12-04 14:37:42 UTC
Initial report is at:
  http://lists.wikimedia.org/pipermail/wikimedia-l/2013-November/128911.html

Webstatscollector has been updated to filter Special:CentralAutoLogin/
(commit 0d7af935f989d5c539a4d2febde93ea0ae62571), and since 2013-12-03 the
new version of webstatscollector is deployed.

The last full file of the old webstatscollector is:
  http://dumps.wikimedia.org/other/pagecounts-raw/2013/2013-12/pagecounts-20131203-190000.gz

The file of the switchover is:
  http://dumps.wikimedia.org/other/pagecounts-raw/2013/2013-12/pagecounts-20131203-200003.gz

The first full file of the new webstatscollector is:
  http://dumps.wikimedia.org/other/pagecounts-raw/2013/2013-12/pagecounts-20131203-210005.gz



Filtering of webstatscollector between mid July 2013 and 2013-12-03 is still
to be done.

Comment 6 Tilman Bayer 2013-12-10 03:59:12 UTC
Thanks for spotting and fixing this.

Could the note about this correction also be added to the other pages on stats.wikimedia which are affected by this, e.g. 
http://stats.wikimedia.org/EN/TablesPageViewsMonthlyAllProjects.htm ?
