Hi Prometheans, tl;dr: I have just published a draft of a design document about better histograms for Prometheus and would appreciate your feedback: https://docs.google.com/document/d/1cLNv3aufPZb3fNfaJgdaRBZsInZKKIHo9E6HinJVbpM/edit?usp=sharing
As many of you might know, I have been (in-)famously working on histograms for Prometheus from the very beginning of the Promethean era. As Goutham has recently found out, I even mentioned histograms as my favorite Prometheus topic during the very first conference talk about Prometheus ever! (To be precise: It was SRECon Europe on 2015-05-14, during the Q&A, when none less than Brendan Burns asked about the topic.) What we currently have in Prometheus was only ever a prototype, at least from my perspective. (o: In an ideal world, I would have sat down back in 2015 and created the document linked above. Too many distractions by other interesting or even urgent things, I guess. To get the whole narrative, you could check out my recent "histogram trilogy of talks" (which will also give you the gist of the design document): https://fosdem.org/2020/schedule/event/histograms/ https://promcon.io/2019-munich/talks/prometheus-histograms-past-present-and-future/ https://www.youtube.com/watch?v=HG7uzON-IDM The bad news is that even after all those years, most of the work still has to be done. Every layer of the Prometheus stack has to change, which needs a coordinated effort. That's precisely the reason why I created the design document, which you could also call an RFC. After collecting your feedback, I hope to be able to evolve it into something we can agree on as the way forward, serving as a master plan to align the many detailed efforts that will have to follow. I hope you will enjoy the read, at least somewhat... -- Björn Rabenstein [PGP-ID] 0x851C3DA17D748D03 [email] [email protected] -- You received this message because you are subscribed to the Google Groups "Prometheus Developers" group.
