There's already a bunch of discussion of implementation details in T202148.

From the meeting today: Neil / Dan endorsed the latter plan I mentioned in T202148.

That said, it's slightly more work for us in terms of places to add logging to, but I think we'd get cleaner results by logging the various AnnotationAction methods, and separately adding logging to opening the link dialog and the link context's remove-link button. Avoids the mixing up of link annotation actions with the rest of them, and doesn't overrepresent the user-action weight of things like clearing annotations from a heavily-annotated bit of text. (I.e. Neil probably has to do less data-wrangling after we've logged it.)

Neil should make a new schema, and once we know what that will be called we can land a patch for this.

We'll be sending a log event for every relevant event in a sampled session, not throttling them or logging one "feature X was used in this session" event per session or anything like that, in the forms:

• annotation.bold
• dialog.link
• dialog.image

etc.

We'd probably override the clear-annotation button in the link context popup to claim it's a dialog.link action, rather than an annotation action regardless of what it is technically.

@Neil_P._Quinn_WMF should let us know exactly what data we want to log along with those bare-bones facts. We could quite easily log the same data as is currently associated with the Edit schema, or you could just count on joining to those via the session id if that's possible.

Patch hooks up most of the instrumentation. The rest will be in the MW extension (ve.init.mw.trackSubscriber.js), and is blocked on Neil's schema definition.

Throw this into the console to get a sense for what's being logged:

ve.trackSubscribe( 'activity.', function() { console.log.apply( console, arguments ); } );
