Playing with openshift. I've no affiliation to piwik.
The OpenShift php cartridge documentation can be found at:
Piwik is a downloadable, open source (GPL licensed) real time web analytics software program. It provides you with detailed reports on your website visitors: the search engines and keywords they used, the language they speak, your popular pages, and so much more. Piwik aims to be an open source alternative to Google Analytics, and is already used on more than 150,000 websites.
More information can be found on the official Piwik website at http://piwik.org
