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.

Yeah, I can definitely imagine, especially in some complex use cases. We use it, but not doing nothing too complex, just some build steps or automations for local development

About Rust itself, I can't talk much at the moment, I'm on the very beginning, so I'm still trying to understand the barebones. One thing that for sure I can say, and I think it's obvious, is the fact that you write a lot of code while comparing with GoLang, Rust is very verbose IMO

010

Nicolas Takashi @ntakashi.com · 21/06/2025

kube-rs is very straightforward, but you need to write a lot of things by yourself, at least this is my experience while working on this during a week.

Nicolas Takashi @ntakashi.com · 21/06/2025

So far it's going ok, I'm missing some shortcuts that kubebuilder offers, like the scaffolding using kubebuilder cli and also the whole testing structure we have available.

Nicolas Takashi @ntakashi.com · 20/06/2025

I won’t lie for a moment o was thinking about about and just go with old and good golang + kubebuilder

100

Nicolas Takashi @ntakashi.com · 20/06/2025

Rust isn't very expressive and you need to type a lot more than golang. Error handling was killing me haha

Nicolas Takashi @ntakashi.com · 20/06/2025

Writing a simple controller took me some time to be honest. Even with Cursor auto completion it wasn’t that easy, docs are not clear about how kube-rs works

100

Nicolas Takashi @ntakashi.com · 20/06/2025

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

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 🙌

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 🕓

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 :)

I might be a bit bias, but I just like go sdk especially because it’s so easy integrate with other tools on the ecosystem like promql package to lint and transform promql expressions.

Nicolas Takashi @ntakashi.com · 04/03/2025

Amadeus, Chronosphere and RedHat is using it not only scheme but core components as well. Dash0 is relying their dashboard solution bases on the Perses Dashboard Scheme. We already have other people talking about adoption like Logz.io

KKkk! That time renovate will not save me, tons of breaking changes on the npm modules

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...

One thing I'm not sure if it's considered a mistake, but I think it's quite weird is always re-enqueue the reconcile of a object even if the first reconciliation is successful.

I’m even sad to see that it is so usual people think they are better and smarter by the complexity of the software they’re writing and how powerful and complex the language they’re using to build and ship is. 🫠

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!
