This lesson is for Java/JVM developers who want to build observable, production-worthy systems. This lesson examines the nonfunctional or cross-functional capabilities that all applications need in order for developers to operationalize them. The lesson focuses on observability-a measure for how well internal states of a system can be inferred by knowledge of its external outputs.
