The event-driven architecture (EDA) presents unique challenges in terms of monitoring and troubleshooting due to its asynchronous communication pattern. To effectively monitor an EDA, it is essential to implement distributed tracing, collect telemetry data that provides detailed insights into performance and efficiency, detect errors immediately, and view all services, components, and dependencies cohesively. A unified observability platform like Datadog can help organizations gain a holistic understanding of their EDA's performance and make informed decisions about optimization. By leveraging tools like Data Streams Monitoring (DSM) and distributed tracing, organizations can identify bottlenecks, detect errors, and improve overall system efficiency.
