Dokuwiki is a popular wiki software, similar to Mediawiki. “It is a standards-compliant, simple-to-use wiki which allows users to create rich documentation repositories.”
Heikki, a Finnish user of Piwik, has developed a plugin for easy integration of Piwik in Dokuwiki. This plugin allows you to track visitors statistics of your DokuWiki installation using Piwik. Optionally admin/users can be excluded from the statistics.
Thanks Heikki for your work!
