1858518 - [META] Validate Glean and Geckoview Streaming Collected Data

Status: RESOLVED FIXED

(Data Platform and Tools :: Glean: SDK, task, P2)

Description

[Perry McManis [:perry.mcmanis]]

This is a meta bug to cover the efforts to validate data collected by Glean and data collected by Geckoview Streaming against each other.

For a long time, Geckoview did not support sending Gecko metrics (e.g. performance) via Glean. Subsequently, anyone looking to collect data in Geckoview had to make use of a temporary solution to that problem; Geckoview Streaming, which you can read more about in this This Week in Glean entry. However, Geckoview streaming was a temporary solution and is now deprecated.

Now that Fenix has migrated to the monorepo, there is a large set of Networking probes marked for potential migration. However, for this effort to proceed, we must establish that existing metrics once migrated will be identical, and that new metrics implemented directly via glean will behave consistently with prior metrics. That is, in the case where each system is collecting the same measure, we expect to see near as makes no difference discrepancies between the two.

At the highest level, this work means re-instrumenting a few existing metrics directly in glean, and checking a new metric collected in both, and following the new Data Science guidelines for performing a valdation. Please see the plan bug for specific details.
