Welcome to my personal blog, where I will share mostly writings on software development and maybe the occasional update from my personal life.
PromCon 2025
Another year, another PromCon! During PromCon EU 2025, which took place in Munich October 21-22, I shared a talk with my colleague Owen Williams.
Together we talked about the improvements that have gone into Prometheus' OpenTelemetry (AKA OTel) functionalities since PromCon 2024. Significant improvements have been made, both on the functional and the performance side of things.
Some of the points from our talk:
-
Translation of metric and label names in the OTLP endpoint is now optional
-
OpenTelemetry scope metadata can now be included as metric labels
-
Initial support for delta temporality metrics is now available
-
OpenTelemetry non-exponential histograms can now be converted into native histograms with custom buckets
Prometheus Info Function Blog Post
I’ve blogged for the first time for the Prometheus project!
The blog post is about the PromQL function Björn Rabenstein and I authored together: info.
While info is still considered experimental, we recommend it as the best method for including OpenTelemetry resource attributes in Prometheus queries.
