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 Data Collection Review [2] and patch to extend their expiry. There is a shorter form for data collection renewal [3].

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.
