For Prometheus 3.10.0, I built a new PromQL feature: you can now specify default values for missing series in binary operations!
Thanks to @dash0.com for inspiring and sponsoring the development of this feature.
Here's how it works and what you have to watch out for:

I wrote a about exciting and ambitious changes we are making in @cncf.bsky.social @prometheus.io project:
prometheus.io/blog/2026/02...
Diving into the potential future of the "native" model for the composite metric types in Prometheus. 💪
Side projects, blog, podcasting is hard with 2 small kids, but I eventually managed to find time for a blog! (PS: I had to switch to 5am routine 🙈)
Wrote some words about #lazygit OSS tool and what we can learn from its UX. Enjoy! 🤗
bwplotka.dev/2025/lazygit/
Haha! Hope we made reasonable arguments 🙈
Believe it or not, Go! 🙂
With github.com/bwplotka/mimic and magefile.org, you can basically set targets, that'll get you YAML from Go structs. And it being in Go means easy templating, IDE support, so you can actually look through what you are configuring, and things panic when something is wrong.
Applications for @prometheus.io LFX mentorships open today!
We have some really impactful projects this time, around Prometheus <-> OTel UX, Remote Write 2.0, and Native summaries.
Go apply to work with some really cool folks, and learn while you're at it!

Just published a very opinionated 🔥 blog post on why I still recommend using Prometheus's native instrumentation libraries over @opentelemetry.io, especially if you mainly care about metrics and using them with @prometheus.io:

Reminder: The CfP for #PromCon (October 21+22 in Munich) is open! Please submit your @prometheus.io talks :)

#Perses just got easier to adopt! 🚀
We’ve launched a new repo featuring your favorite OSS project dashboards, built with the Perses Go SDK and packaged as reusable Go modules.
Learn more and start using them today:

I gave an improvised talk about building a new prometheus.io homepage at the Berlin @prometheus.io meetup and then live-launched the new site during the talk 😅 Here's a recording, starting at 7m30s in this live stream recording:

It was super nice getting to meet and chat with everyone at #KubeCon!
Safe travels back home!
Ready for your Thanos questions! 🙂
Come and say hi! 🙂
I've just updated all of my Prometheus monitoring trainings at training.promlabs.com to Prometheus v3 and also updated most other component versions (Alertmanager, exporters, Prometheus Operator, SDKs, ...) to keep things fresh.
Check out the trainings if you want to learn @prometheus.io :)
Happy New Year! 🎊🎉
Excited for the year up ahead!
please stop using chatgpt to write your conference talk submissions. we can tell.
This has also been my experience reviewing some mentee question responses for LFX...
The AI text always ends up reading as too generic!

This has happened to me so many times! I always leave the tab for a pending review open, so I know what reviews I need to submit/complete...but too many tabs
Try it out and let us know if you face issues!

This release is brought to you from 11891m (39017ft) with 1022km/h (635mph) above the UK approaching Amsterdam coming back from Salt Lake City KubeCon. ✈️
I built a silly usage of the Bluesky Firehose just to get my feet wet and see what was possible. It's kinda fun to just watch. www.emojirain.lol
My PVLDB paper announcement bot now supports Bluesky: @pvldb.bsky.social
I am letting it post papers from last issue (August 2024). It will then hit the new volume when it pops later this year.
