Application friendly name: whatever Desktop Firefox is -- I can't see it in https://probeinfo.telemetry.mozilla.org/glean/repositories.

Application ID: whatever Desktop Firefox is, with -backgroundupdate appended. So I think that's desktop-firefox-backgroundupdate.

Description: I don't know what this is supposed to be. Maybe:

The Desktop version of Firefox's background update tasks.

Repository URL: this lives (will live) in mozilla-central, i.e., https://github.com/mozilla/gecko-dev

Locations of metrics.yaml files (can be many):

• toolkit/mozapps/update/metrics.yaml

Locations of pings.yaml files (can be many):

• toolkit/mozapps/update/pings.yaml

Dependencies*:

• glean-core
• org.mozilla.components:service-glean

It's not clear to me if desktop-firefox should be a dependency, in the light of future tickets like Bug 1703313, which would share data.

Retention Days: whatever Desktop Firefox is, or 180 if that's too long

This slack thread has some relevant context: https://mozilla.slack.com/archives/CEE12R4E8/p1618334112045000

Some care may need to be taken here, as this is not a "normal" variant (in the sense that e.g. Firefox for Android Nightly is a variant of Firefox for Android).

Hey Nick, thanks for filing this! After some discussion, we're going to expose this as a new Glean application.

Let's leave off firefox-desktop and org.mozilla.components:service-glean as dependencies. The former we can add later if we need to, and the latter is Android only.

Is firefox-desktop-background-updater for app_name acceptable?

Let's make it firefox-desktop-background-update -- i.e., no trailing r. That matches the ping name, and in general we refer to everything as "background update".

:frank -- next steps here?

The pings will in fact be in:

toolkit/mozapps/update/metrics.yaml
toolkit/mozapps/update/pings.yaml

This was necessary to land these patches. Sorry for the change!

Per discussion on Slack, :wlach is going to finalize this with his PR.

https://github.com/mozilla/probe-scraper/pull/304 has been merged and destination tables in BQ now exist to support this new app_id:

Ping: https://dictionary.protosaur.dev/apps/firefox_desktop_background_update/pings/background-update
Table: https://dictionary.protosaur.dev/apps/firefox_desktop_background_update/app_ids/firefox_desktop_background_update/tables/background-update

The final app_id is "firefox.desktop.background.update".

Since the PR has landed, I think this is done. I'll re-open if the data isn't actually present when I check on Monday. Thanks, all!
