The NavigationTiming extension allows logging perceived latency measurements, exposed by browsers as part of the proposed Navigation Timing API, which «defines an interface for web applications to access timing information related to navigation and elements».

What data is logged?[edit | edit source]
- See the NavigationTiming JSON EventLogging schema.
- Browsers[1] accounting to about 11 % of WMF's requests (as of April 2013) are not supported.
How is the information used?[edit | edit source]
Engineers at the Wikimedia Foundation intend to use this data to assess the impact (positive and negative) of changes to code or server configuration, and thus to help guide ongoing work on site performance.
Sample configuration[edit | edit source]
require_once( "$IP/extensions/EventLogging/EventLogging.php" ); // required dependency require_once( "$IP/extensions/NavigationTiming/NavigationTiming.php" ); $wgNavigationTimingSamplingFactor = 10000; // log 1:10,000 requests.
