Performance monitoring with OpenTracing, OpenCensus, and OpenMetrics

The article discusses how to effectively trace requests through asynchronous, event-driven architectures using distributed tracing. It explains the difference between parent-child spans (for direct, synchronous calls within a service) and span links (for asynchronous events flowing between services), highlighting that using the right relationship type is crucial for accurate tracing and understanding system behavior. Choosing between these methods depends on whether the event is a direct response to a request or a separate, independent action.
