During this workshop, we will build fully operational observability stack using OpenTelemetry, Mimir, Grafana, and other notoriously known tools. We will explore the key differences between Prometheus and OpenTelemetry + Mimir OSS. By the end of the workshop, you will understand basic functionalities of all mentioned and be capable of configuring and deploying them in a way that you will never lose metrics again!

We'd like to ask all attendees to pre-pull all docker images and pre-create their local kubernetes environment before the workshop, so we can avoid any troubles with internet connection. All instructions are written in the readme: https://github.com/obabec/devconf2026-workshop-obs/blob/main/BEFORE_CONFERENCE.md
