Description
Currently, prometheusreceiver supports native histograms, but prometheusexporter cannot expose them (because Prometheus cannot expose native histograms in text format yet).
Steps to Reproduce
- Instrument your code with native histograms
- Scrape the metrics with
prometheusreceiver by following the instructions here: https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/f5d54da37ae664e1a0b6934a61d38f1afab5501f/receiver/prometheusreceiver/README.md#prometheus-native-histograms
Expected Result
prometheusexporter should expose native histograms
Actual Result
