Switch to new UseCounter histograms |
||||||||||||
Issue descriptionI'm making a number of fixes to the UseCounter infrastructure (see blocked on bugs). When all of that is done and validated I will: 1) Update the new histogram name from WebCore.UseCounter_TEST to Blink.UseCounter 2) After the release with the above hits stable, mark the WebCore.FeatureObserver histograms as "deprecated" 3) Add the new histogram data to the public chromestatus UI somehow 4) Delete all the LegacyCounter code and obsolete FeatureObserver histograms.

Ericbidelman@ and I agree that we'll work to get this supported in chromestatus in Q1, flipping it live sometime early Q2 (after M57 has been stable for awhile). Next step is to start a discussion with uma-team about exposing a new v2 endpoint. See https://github.com/GoogleChrome/chromium-dashboard/blob/master/admin.py#L45
