I thought the ocregistry was still used by some of the contrib components that use opencensus, is that no longer the case?

[codeboten]

Contrib still uses opencensus: https://github.com/search?q=repo%3Aopen-telemetry%2Fopentelemetry-collector-contrib+go.opencensus.io%2Fstats&type=code

See open-telemetry/opentelemetry-collector-contrib#29867

[bogdandrutu]

The stats module in opencensus it is it own producer registered, this registry was only for the process metrics :)

[codeboten]

My bad, I was confusing this producer registration for the one in the exporter configuration

opentelemetry-collector/service/internal/proctelemetry/config.go

otelprom.WithProducer(opencensus.NewMetricProducer()),
