1687312 - Add telemetry to find out why some android users aren't getting webrender

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, task)

Description

[Jamie Nicol [:jnicol]]

Jim was looking at some telemetry and found that quite a lot of Mali-G users running 84 are not getting webrender: https://sql.telemetry.mozilla.org/queries/77336/source. They should be. There are also a smaller number of Adreno 5xx (not 505 or 506) and 6xx users without webrender.

We should expose the gfx.features.webrender.status telemetry probe to geckoview_streaming so that we can find out why.

These used to be in the gfx.webrender namespace, but were accidentally
moved to a different namespace when an unrelated probe was added to
the wrong place in the file.

Depends on D102211

We have noticed that a sizeable number of Fenix users are not getting
webrender when they should be. On desktop the existing
gfx.feature.webrender telemetry probe is used to determine why
webrender is not enabled. Expose this to geckoview_streaming telemetry
so we can tell the same for Fenix users.

Depends on D102212

DATA COLLECTION REVIEW RESPONSE:

Is there or will there be documentation that describes the schema for the ultimate data set available publicly, complete and accurate?

Yes.

Is there a control mechanism that allows the user to turn the data collection on and off?

Yes. This collection is Telemetry so can be controlled through Firefox's Preferences.

If the request is for permanent data collection, is there someone who will monitor the data over time?

Yes, Jamie Nicol is responsible.

Using the category system of data types on the Mozilla wiki, what collection type of data do the requested measurements fall under?

Category 1, Technical.

Is the data collection request for default-on or default-off?

Default on for all channels.

Does the instrumentation include the addition of any new identifiers?

No.

Is the data collection covered by the existing Firefox privacy notice?

Yes.

Does there need to be a check-in in the future to determine whether to renew the data?

No. This collection is permanent.
