1809322 - Include the total duration of foreground use over the metrics ping measurement window in the metrics ping

Status: NEW

(Firefox for Android :: Experimentation and Telemetry, enhancement)

Description

[Christian Sadilek [:csadilek]]

From github: https://github.com/mozilla-mobile/fenix/issues/8586.

Why/User Benefit/User Problem

It's often useful to understand how much time a user has spent directly interacting with the browser. Duration of foreground use is only available in the baseline ping, but essentially all other interesting metrics for experiment analysis are in the metrics ping. Having to touch another table to do the analysis makes analysis more complex and the measurement windows of baseline and metrics pings are probably not coterminal so it's probably difficult to do it in a strictly correct way.

#4456 is another example of tracking a usage metric (URI count) in the metrics ping.

What/Requirements

The metrics ping should have something like a foreground_duration metric that describes the total foregrounded duration over the measurement window of the metrics ping.

Acceptance Criteria (how do I know when I’m done?)
