Tracing is one of the three pillars of observability. Tracing artifacts of WSO2 Micro Integrator is important to observe, identify possible bottlenecks in a message flow, and debug them. WSO2 Micro Integrator facilitates tracing message flows and publishing the traces based on the OpenTelemetry standard, using multiple tracers, namely: OpenTelemetry Protocol (OTLP), Jaeger, Zipkin, Log & Custom Tracer. This screencast outlines important concepts of OpenTelemetry based distributed tracing in WSO2 Micro Integrator, followed by a demonstration of publishing traces using the OTLP Tracer to New Relic APM, when invoking a simple API.
