This is a solid real-world walkthrough of using OpenTelemetry beyond the usual web/app stack. Instrumenting a Minecraft server may sound niche, but it’s actually a great example of how observability tools can be extended to domain-specific systems that weren’t designed with telemetry in mind.

What I found especially useful was the seamless integration of the Java agent for JVM metrics and Prometheus exporters for game-specific insights. It shows how OpenTelemetry isn’t just about “enterprise-grade” services — it can be lightweight and flexible enough for modding or personal projects too.

Also worth noting: using Dash0 as the backend provides a good alternative to the usual Grafana/Loki stack. Curious if others have explored this combo in non-gaming contexts?

Overall, this piece reinforces the idea that observability is no longer optional, even for hobbyist servers. Would love to see more OSS projects pre-instrumented for OpenTelemetry out of the box.
