Hi all!
The wikistats or as it is better known '
stats.grok.se' code as referenced in the mentioned URL visualizes traffic data collected by webstatscollector. Webstatscollector does collect traffic for the wiksource projects and the identifier is '.s' in the pageview datafiles as they are available on
http://dumps.wikimedia.org/other/pagecounts-raw/
So the data is available, it could be that the
stats.grok.se code does not store the wikisource pageview data in the MySQL db that it uses.
Hope this helps.
Best,
Diederik
