1736627 - Remove or update probes expiring in Firefox 96: HTTP*

Status: RESOLVED FIXED

(Core :: Networking: HTTP, task, P1)

Description

[telemetry-probes]

The following Firefox probes will expire in the next major Firefox nightly release: version 96 [1].

HTTP3_UPLOAD_TIME_10M_100M
HTTP3_UPLOAD_TIME_GT_100M
HTTP_PRELOAD_IMAGE_STARTREQUEST_DELAY
DOCUMENT_PRELOAD_IMAGE_ASYNCOPEN_DELAY

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.

Your Friendly, Neighborhood Telemetry Team

The following probes should stay in place but we should let them expire. We plan to use hem again in the future.
HTTP3_UPLOAD_TIME_10M_100M
HTTP3_UPLOAD_TIME_GT_100M

These probes should be updates:
HTTP_PRELOAD_IMAGE_STARTREQUEST_DELAY
DOCUMENT_PRELOAD_IMAGE_ASYNCOPEN_DELAY

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

[Tracking Requested - why for this release]:

The expired probes cause a permanent test failure of netwerk/test/unit/test_http3_large_post_telemetry.js on Linux and macOS debug. I will disable the test temporarily to get central green again. This had been missed because there was another test failure for the task in the version increase simulations and this failed only on two platforms.

Dragana, how can we best ensure that if we re-enable the H3 upload time probes, we will also re-enable the tests?

Also, for the probes to be renewed, we need to answer "Why was the initial period of collection insufficient?" in the data review. What's the reason?

Comment 6

[Dragana Damjanovic [:dragana]]

The project that was using this probes got postponed therefore we need to extend the probes.
