1566393 - Review expired scalars for inspector webcomponents support

Status: RESOLVED FIXED

(DevTools :: Inspector, task, P3)

Description

[Julian Descottes [:jdescottes]]

We have several expired telemetry scalars for devtools inspector webcomponents support. We should either remove them entirely or update their expiry.

Scalars:

• devtools.shadowdom shadow_root_displayed (expired in 66) (searchfox)
• devtools.shadowdom shadow_root_expanded (expired in 66) (searchfox)
• devtools.shadowdom reveal_link_clicked (expired in 66) (searchfox)

Depends on D38291

See input from Harald at https://bugzilla.mozilla.org/show_bug.cgi?id=1566383#c2
We would like to revive those scalars to help us monitor usage of inspector shadowdom features.

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. This collection is Telemetry so is documented in its definitions file [Scalars.yaml](https://hg.mozilla.org/mozilla-central/file/tip/toolkit/components/telemetry/Scalars.yaml) and the [Probe Dictionary](https://telemetry.mozilla.org/probe-dictionary/).

    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, :jdescottes 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 2, Interaction.

    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.
