In this talk, Jonatan Ivanov (Micrometer, Spring Cloud Sleuth) and Moritz Halbritter (Spring Boot) peek under the covers of the observability support in Spring Boot. What is all the stuff that Spring Boot automatically configures for you? How are exemplars implemented? How can you take your system to the next level? What else can you find in Spring Boot and related technologies to look under the hood of your running system (e.g., Spring Boot Actuator, Logbook, Eureka, Spring Boot Admin, Swagger, Spring HATEOAS)? These are just some of the topics we’ll cover in this talk.
