A 2026 survey shows interoperability between OpenTelemetry and Prometheus has improved markedly: the ease-of-use score climbed from 3.1 to 3.6, and the share who find them hard to combine fell from 29% to 10%. For an SRE team still on the fence, now is the time to consolidate on the OTel Collector without abandoning Prometheus.
Kubernetes 1.37 enables Prometheus native histograms by default, replacing static buckets with dynamic exponential buckets. Components stay backward-compatible via dual exposition: enable scrape_native_histograms, then migrate your histogram_quantile queries.
On September 11, 2026, Kubernetes 1.37 graduated Prometheus native histogram support to beta, enabled by default. Latency metrics now expose dynamic exponential buckets that can reduce time-series count by up to 90%, provided you follow the four-step migration.
Datadog charges $15 per host per month for infrastructure, $31 for APM, and $0.10 per gigabyte of ingested logs. Grafana, Prometheus, Loki, and node_exporter deliver the same coverage on a single Docker Compose stack, on Linux or Windows, for the cost of hardware and electricity.
