Kubernetes v1.37: Native Histograms Graduates to Beta
Kubernetes v1.37 graduates native histogram support for Kubernetes metrics to Beta and enables it by default. Components expose classic histogram buckets alongside Prometheus native histogram spans in the same Protobuf payload, using a bucket factor of 1.1 and a cap of 160 buckets. Prometheus 3.x users can enable scraping per job with scrape_native_histograms and keep classic series with always_scrape_classic_histograms.
What changes for platform teams
Platform teams running Prometheus should plan to migrate dashboards and alerts from _bucket queries to native histogram queries while keeping always_scrape_classic_histograms true during transition. Rollback is available by setting scrape_native_histograms to false or disabling the feature gate.
