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...

Visualizing Target Relabeling Rules in Prometheus 3.8.0 | Prometheus

An open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach.

#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.

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

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 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...

Kubernetes annotation-based discovery for the OpenTelemetry Collector

In the world of containers and Kubernetes, observability is crucial. Users need to know the status of their workloads at any given time. In other words, they need observability into moving objects. Th...

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...

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I went to write a new blog post about Thanos and OpenTelemetry, but my personal blog wasn't even building because of outdated dependencies 😅 Hopefully I didn't break anything during the upgrade

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.

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.
