Everything you need to know about OpenMetrics 2.0!
summary
OpenMetrics 2.0 proposes a writable, UTF‑8 text exposition that encodes complex types so you can see and query the same thing: it adds native histograms in text, moves created timestamps into a per-sample tag (ST start timestamp tag), relaxes enforced metric suffix rules to avoid name-mangling with OpenTelemetry, and keeps a protobuf flavor for fast development. Implementations report concrete wins — about 10x faster on histograms and ~2x CPU parsing — and design work addresses federation conflicts and stateless scraping.
