Have been using Open Telemetry with Micrometer in a Spring Boot 3 microservices architecture. I have to say (regardless of framework of programming language) : structure your logs (like the article mentioned), use the tracing ID propagation and collect the logs in something like Elastic. This makes analyzing logs nice, especially if you’re in a Kubernetes cluster with many services with multiple pods.
Nitpick: a lightyear is a measure of distance, not of time :)
