Extension:XAnalytics

The XAnalytics extension is used on Wikimedia wikis to communicate analytic information from MediaWiki to Wikimedia's logging infrastructure. See X-Analytics for more details.

Installation
You probably do not want to use this extension on your own wiki. If you do want to use it, its only useful if you also set up all the logging infrastructure that Wikimedia has.

Hooks
This extension adds a custom hook named XAnalyticsSetHeader, which is given parameters OutputPage $out and Array &$headerItems. Other extensions can use this to add additional items to the X-Analytics header.
