Event-driven architecture (EDA) is widely used in industries like retail banking, capital markets, e-commerce, and airlines. However, integrating end-to-end tracing and observability into an EDA system is difficult due to the multitude of microservices connected to the event broker. Questions arise about event sources, destinations, failed messages, and message queues within the broker - to name a few. Effective troubleshooting requires distinct traces and span links between producers, consumers, and the broker itself

In their talk, developer advocates Tamimi and Henrik delve into EDA system development and the challenges and advantages of observability in EDA. They explore how advanced observability backends can trace all events in an EDA and highlight the impact of the OpenTelemetry community on improving messaging observability. Attendees will gain insights into achieving comprehensive observability in EDA systems, enabling enhanced understanding and troubleshooting capabilities.
