Is your feature request related to a problem? Please describe.
Currently, outdated feeds (lastUpdated + ttl is more than a few update cycles ago) are not reported via metrics.
Goal / high level use-case
We'd to be able to issue monitoring alerts in case a feed has not been updated for a while.
Describe the solution you'd like
Periodically, for every provider and feed, the feed should be checked if it's overdue or not and this metric registered with the metrics service.
Describe alternatives you've considered
None
Additional context
I'm working on a PR which adds a MetricsUpdater(I'm open for better naming suggestions) which every n seconds iterates over all cached feeds and registers the overdue metric (0 (not overdue) / 1 (overdue)). Another option might be the number of seconds overdue (lastUpdated+ ttl - now), which would allow triggering different actions depending on the number of seconds a feed is overdue...
