This page holds a JSON schema that specifies a data model for EventLogging.

Sampling rate and method[edit]
As of September 2017: 10% of all distinct browser sessions, determined using the pseudorandom mw.user.sessionId() value (an ephemeral cookie)
Each action is only logged once per page view. That is, no matter how many times the user clicks on 'Printable Version', only one 'clickPrintableVersion' action is logged for that page until the page is refreshed. Ditto the `onBeforePrint` action.
As of October, 31st (see phab:T208454), the Print schema is disabled in production. Phuedx (WMF) (talk) 15:01, 14 December 2018 (UTC)
