We introduced distributed tracing, central logging with trace correlation and monitoring with Prometheus and Grafana in a large internationally distributed software development project from the beginning. The result: Nobody used it.

In this talk we show the good and not so good sides we have learned while introducing and operating the observability tools. We show which extensions and conventions were necessary in order to carry out a cultural change and to awaken enthusiasm for these tools. Today the tools are a first-class citizen and people are shouting when they are not available.
