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
It was really fun and inspiring to be back at PromCon, and it was a true privilege to be able to share with the audience what my fellow contributors and I have been working hard on. Thanks to Google for hosting us at their amazing Munich HQ!
