Status: RESOLVED FIXED

(Firefox :: Search, task)

Description

[telemetry-probes]

The following Firefox probes will expire at the end of Firefox nightly release: version 144 [1].

browser.searchinit.secure_opensearch_engine_count
browser.searchinit.insecure_opensearch_engine_count
browser.searchinit.secure_opensearch_update_count
browser.searchinit.insecure_opensearch_update_count

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 patch to extend their expiry.

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.

Given that these 4 Legacy Telemetry scalars are mirrored to Glean metrics of the same name, we are going to completely remove the legacy scalars. (I'll post a patch for this shortly.) I've run 4 SQL queries which have verified that the counts for the legacy telemetry scalars and the corresponding Glean metrics match closely enough that we are comfortable removing the scalars.

• OpenSearch User Counts (Legacy Telemetry scalars) - August 2025
• OpenSearch User Counts (Glean metrics) - August 2025
• OpenSearch Users with OpenSearch Engines with Updates Counts (Legacy Telemetry scalars) - August 2025
• OpenSearch Users with OpenSearch Engines with Updates Counts (Glean metrics) - August 2025
