The State of OpenTelemetry for Java Developers by Philipp Krenn

OpenTelemetry, or OTel for short, is taking over the observability world to uncover all kinds of performance problems or errors. Let’s look at that hands-on. This talk dives into the background of OTel including the technologies its building on (or replacing). It also takes a look at what auto-instrumentation can and cannot achieve. As well as the latest developments beyond tracing with metrics and the first steps towards logging. This talk also takes a look at different approaches of integration — the Spring ecosystem is wrapping most of OTel into Micrometer while other frameworks are not. What are the pros and cons of these different integrations for the developers.
