1754639 - Remove or update probes expiring in Firefox 100: STARTUP_CACHE_REQUESTS before Gecko version increases to 100 on 2022-03-08

Status: RESOLVED FIXED

(Core :: XPConnect, task)

Description

[telemetry-probes]

The following Firefox probes will expire in the next major Firefox nightly release: version 100 [1].

STARTUP_CACHE_REQUESTS
SCRIPT_PRELOADER_REQUESTS
SCRIPT_PRELOADER_WAIT_TIME
script.preloader.mainthread_recompile

What to do about this:

1. If one, some, or all of the metrics are no longer needed, please remove them from their definitions files (Histograms.json, Scalars.yaml, Events.yaml).
2. If one, some, or all of the metrics are still required, please submit a Data Collection Review [2] and patch to extend their expiry. There is a shorter form for data collection renewal [3].

If you have any problems, please ask for help on the #data-help Slack channel or the #telemetry Matrix room at https://chat.mozilla.org/#/room/#telemetry:mozilla.org. We'll give you a hand.

Tracking because js/xpconnect/tests/marionette/test_preloader_telemetry.py depends on it.

Please keep in mind this must be resolved by the end of the week.

Request for Data Collection Renewal

** This form is for the renewal of an existing, reviewed data collection.**

** All questions are mandatory.
You must receive Data Review from a
Data Steward
on a filled-out Request before shipping your renewed data collection.**

1. Provide a link to the initial Data Collection Review Request for this collection.
   https://bugzilla.mozilla.org/show_bug.cgi?id=1364235#c25
2. When will this collection now expire?
   In about a year (FF version 116)
3. Why was the initial period of collection insufficient?
   The probes contain performance information which continues to be useful.

I don't see why this would stop being relevant. We want to continue having
historical information on this even if we're not actively looking at it today.
