While working on the integration of the YouTube playback performance tests into Raptor, and correctly reporting the results to perfherder I noticed a really high noise for Aarch64 and MacOS, which requires us to disable alerting for those platforms.
Sadly Perfherder doesn't allow to enable / disable alerting for specific platforms or tests whether on the suite nor sub-test level. Instead the results as pushed by the client have to be updated, by having
shouldAlert set appropriately.
It would be great if sheriffs could manage that via perfherder directly.
