Prometheus v2.40.0 Release Notes

Release Date: 2022-11-08 // over 1 year ago

  • 🚀 This release introduces an experimental, native way of representing and storing histograms.

    It can be enabled in Prometheus via --enable-feature=native-histograms to accept native histograms. Enabling native histograms will also switch the preferred exposition format to protobuf.

    🚀 To instrument your application with native histograms, use the main branch of client_golang (this will change for the final release when v1.14.0 of client_golang will be out), and set the NativeHistogramBucketFactor in your HistogramOpts (1.1 is a good starting point). Your existing histograms won't switch to native histograms until NativeHistogramBucketFactor is set.
