1923031 - Can we avoid recording networking.http3_enabled on content processes?

Status: RESOLVED FIXED

(Core :: Networking: HTTP, enhancement, P2)

Description

[Florian Quèze [:florian]]

The networking.http3_enabled telemetry scalar landed in bug 1652104. It is recorded in both the parent process and content processes. This is annoying when trying to migrate scalars to Glean, as the Boolean metric type in Glean is only supported in the parent process.

Is recording this information on child processes really useful? Isn't it controlled by the value of a preference, and always the same on the parent end child processes?

The code recording the data is at https://searchfox.org/mozilla-central/rev/b546e74055186bb387ed7db9079374e1e7e0b88e/netwerk/protocol/http/nsHttpHandler.cpp#413-414
