I Can See Clearly Now: Observability of JVM & Spring Boot 2-3-4 apps @ Spring I/O 2026

This talk covers the essential aspects of making Java, JVM, and Spring Boot applications observable, particularly for those running applications in production. The speakers, Jonatan Ivanov and Tommy Ludwig, guide the audience through using modern toolsets like Micrometer, OpenTelemetry, Grafana, and Prometheus to instrument applications effectively and gain insights into their behavior. They emphasize avoiding vendor lock-in while ensuring applications can communicate their inner workings clearly. Attendees can expect engaging live demos and practical advice, regardless of their prior knowledge of observability concepts.
