Distributed tracing allows you to see how a request progresses through different services and systems, the timing of each operation, any logs and errors as they occur.
OpenTelemetry Tracing is particularly valuable in the context of microservices architecture, where applications are composed of multiple independent services working together to fulfill user requests.
Java agents are a special type of class which, by using the Java Instrumentation API, can intercept applications running on the JVM, modifying their bytecode.
