Today the smartics Integration for Piwiki has been released as an add-on for Confluence! The add-on is available on the Atlassian Marketplace for free.

Piwik is the leading open-source analytics platform that gives you more than just powerful analytics. Confluence is your platform where work becomes teamwork. This add-on makes integrating calls to the Piwik API from your Confluence pages much easier!

Instead of adding HTML and JavaScript code to a page, simply add a macro and provide the API call information.

<script type='text/javascript'>
   var _paq = _paq || [];
   _paq.push(['setDocumentTitle', 'My Title']);
</script> 

Currently integration to Piwik is supported by the following macros:

Document Properties

Provide document properties to the Piwik context.

Set Multiple Custom Variables

Provide a set of custom variables to the Piwik context.

Set One Custom Variable

Provide a single custom variable to the Piwik context.
