To learn more, see our tips on writing great answers. Implement distributed tracing using Spring Cloud Sleuth 3. gathers and saves metrics as time series data, which means that metrics data is kept alongside the You can manually set the span and trace id using TraceContext.newBuilder() in a test and past the Tracer into the class being tested. Prerequisites Send Data to Wavefront Examine Inventory Data Examine RED Metrics and Traces Next Steps In this tutorial, you use Wavefront for Spring Boot with the Spring pet clinic sample application. Let's take a look at a simple example which uses Spring Cloud Sleuth to trace a request. In this example, the API call done on A triggers an API of B.
