Re: Measuring Australis…

After chatting with Irving yesterday (and Mark this morning) I’ve added some notes to the bottom of the etherpad.

tl;dr - Yes, I believe we can use telemetry as-is for these types of probes, although it’s not quite as easy as it could be.  One of Irving’s suggestions is that we might want to add a new UiTelemetry.jsm, to make it easier to log UI events…

I’m also looping in Gregg Lind, one of the UXR Quants, to let us know whether it’s easier for post-analysis to store the action separately from the UI used to invoke it or not.

I mean, we've put a lot of work into the design of Australis, and we have some goals for how we want it to change user behaviour, but we don't know whether people will react to it in the way we expect.  I also believe that the engineers who have been (and are still) putting a ton of work into landing the new design in a performant way are interested in how their hard work is impacting the people who use Firefox.  Finally, I believe that with a set of Telemetry probes, we can get the answers to most of those questions.
> Firefox for Android wants to start landing the same types of probes for UI telemetry. One of the first things we want to know is: Can Telemetry be used as-is for these probes, or do we need a different type of payload. In Firefox for Android, for example, the UI changes based on portrait or landscape orientation. We'll need to capture that with each probe. We also want to know whether the action, Save to PDF for example, was started via a menu or some other UI. For post analysis of "Save to PDF" it might be easier to store the action ("Save to PDF") separately from the UI ("button", "menu", ...) used to initiate the action.
