Event logging/Mobile

This page documents the results of Event logging analytics on Wikimedia mobile sites.

Background
Event logging allows us to measure usage and performance statistics of specific features on the Wikimedia mobile web.

Section toggling in Beta
Measuring the usage of the section toggling features (section open/close arrow and "jump back a section"/close section feature), and the impact of this navigation feature on client-side performance.

Note: This was a preliminary test of our data-gathering capabilities, not necessarily the way we will move forward with eventlogging in the future.

Section toggles
Below is a list of section toggle and "jump back/close section" actions performed in a ~12 hr slice of the data with about 60,000 observations. Sections and jump back actions are numbered according to order from top to bottom of the page (section 0 is lead section, section 1 is first section from the top, etc.).
