Are you using target relabeling rules in @prometheus.io? I wrote a short blog post about the new relabeling rule visualizer I built that just got released with Prometheus v3.8.0, and which can help you make sense of your rules: prometheus.io/blog/2025/12...

Finally, I managed to take some time and add a page to my blog post with some of the talks I presented, and I found the youtube video available. 100% vibe coded :) ntakashi.com/talks/

#PromCon was amazing, really good to see some old friends and meet new ones. Amazing talks, the energy was so nice, and it’s amazing to see the Prometheus Ecosystem so alive. See you soon folks.

Reminder: The CfP for #PromCon (October 21+22 in Munich) is open! Please submit your @prometheus.io talks :) promcon.io/2025-munich/...

This week I had the opportunity to start writing a new Kubernetes Controller, at Coralogix most of the services are Rust based. So I decided to give a try to rust and kube-rs, since I’m not a rustician, that would be a great opportunity to learning

Foi maneiro demais, valeu mano @carlosenog.dev

Ever wondered what actually happens between your dashboards and Prometheus? I just shipped a new version of prom-analytics-proxy, and wrote about the blind spots it solves in query visibility ntakashi.com/blog/prometh... DMs open, feedback welcome 🙌

A really nice overview of @PersesDev at the #kubeconeu talk by @ntakashi.com and Antoine Thébaud, Limitless Possibilities, Consistent Design: Crafting Dashboards with Perses DaC. #cloudnative #observability #o11y youtu.be/7h70Olo5Uzk

KubeCon EU Dump

I’m glad to be presenting at #KubeCon today! Over 400 attendees signed up to join me and Antoine Thebaud and see how #PersesDev is changing the way we manage dashboards, with consistency, scalability, and code. Let’s craft something better together. See you there at 16:00 🕓

We are ready for Day 2 at #KubeCon! We were excited to talk to so many nice Thanos users yesterday! Let's continue that energy! 💜 Also, catch some lovely guest appearances at the booth from beloved community members like @friedrichge.bsky.social and @ntakashi.com!

Ready for tomorrow, see you around folks. #KubeCon

#KubeCon is right there ✊ on the door. Who will be there too? kccnceu2025.sched.com/event/1txHy/...

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 :)

Come to say Hi 👋

We’re thrilled to announce that #OpenTelemetry Demo 2.0 is here!

FOSDEM FOMO 😰

I use to like the OTel project, especially for traces and logs. But sometimes I feel that we’re just reinventing the wheel. 🤷‍♂️ opentelemetry.io/blog/2025/ot...

With Filip we wrote a blog post explaining the new @golang.org 1.23 "iter" package and its unexpected use case in the Go gRPC world and @thanos.io We also dive into Go coroutines (not goroutines!) that makes new iterators even more special, enjoy! 🤗 bwplotka.dev/2025/go-grpc...

This is a great read!

Today I went to write a new blog post about Thanos and OpenTelemetry, but my personal blog wasn't even building because of outdated dependencies 😅 Hopefully I didn't break anything during the upgrade

🚀 Excited to announce the latest version of prom-analytics-proxy! This update includes fixes and a powerful new feature to visualize metrics usage from dashboards, Prometheus rules, and ad-hoc queries. Here’s a sneak peek at the new metric detail page! github.com/nicolastakas...

Are there any fantastic examples for Go SDKs wrapping HTTP/JSON (REST) APIs? Like, imagine a really good Spotify SDK or whatever. Which ones can you recommend? Using the best standards, little reflection and lots of type-safety.

Now it’s official! I’m thrilled to announce I’ll be speaking at Observability Day alongside @Anthoine Thebaud about Dashboard as Code and Perses. See you all in London, folks!

I'm excited to announce that InfluxDB 3 Open Source Now in Public Alpha Under MIT/Apache 2 License: www.influxdata.com/blog/influxd... We're also releasing an alpha of InfluxDB 3 Enterprise at the same time. This builds on years of effort with Apache Arrow, DataFusion, and Parquet.

⭐ I really love the List feature for GitHub stars. The two I created so far are: - github.com/stars/lilic/... - github.com/stars/lilic/...

I'm playing with a side project, non related to observability at all. Having a lot of fun writing code with NextJS + Hono + Cloudflare workers. Super simple, nice ecosystem. I'm pretty impressed.

Excited for the new Prometheus Operator release! Highlights: 1️⃣ Default Prometheus 3.0.1 2️⃣ Role Selectors for Service/Pod Monitors 3️⃣ OTLP Receiver support 4️⃣ OTLP Translation Strategy Check it out 👉

🔥🔥🔥

Coisa boba, quase 1 anos enrolando o Carlos 😂😂😂

Amazing history, I couldn’t even imagine the number of challenges exists to operate such a large system. This is really impressive www.allthingsdistributed.com/2023/07/buil...

It’s Friday 11PM in my time zone, and I’m solving a bug caused by java.lang.OutOfMemoryError: Java heap space. What do you even expect from a weekend that starts like this? 😅

Excited to announce a new #prom-analytics-proxy feature! 🎉 Working with metrics-usage by #PersesDev to trace any time series—queries, alerts, rules, dashboards. buff.ly/4i9l3MO

There's really no place quite like home. Over the last month and a half, my family and I have been living in an Airbnb while our house was under renovations. We've missed our home so much, and Afonso, in particular, has been yearning for his room and beloved toys.

A first version is almost done, some meta information about a given time series and also a table with aggregated information about expressions using that time series. Some other nice informations will be available soon on this screen as well.

Done! 🎉 I just submitted two talks for next year’s KubeCon! 🤞 Keeping my fingers crossed, now it’s time to wait and see!

I've been working in a feature for #prom-analytics-proxy that will provide an amazing integration and visibility of different places where one time series is being used. This was the first PR: github.com/nicolastakas...

🚀 Just launched a new version of prom-analytics-proxy packed with nice updates! - ✨ Sleek new UI built with #shadcn - 💾 SQLite support for easy data handling - ⚡ Query Shortcuts featuring a set of powerful, commonly-used queries

All PromCon 2024 lightning talks are finally available on YouTube! 📺 www.youtube.com/playlist?lis...

This one was really fun to work on. github.com/prometheus/p...

🚀 Just added a “Query Shortcut” feature! Now get instant access to handy query snippets for insights like longest durations, top expressions, and more. github.com/nicolastakas...
