# Log Tracing with Spring Cloud Sleuth
 
This project shows how to implement tracing in a network of Spring Boot applications.

This application is a service that's not facing the user (a "downstream" service), meaning that 
it is accessed by user-facing services so they can provide their functionality.  

1. Start this service with `./gradlew bootrun`
1. Start the [downstream service](../sleuth-downstream-service/) with `./gradlew bootrun`
1. Open `http://localhost:8080/customers-with-address/{id}` where IDs from 1-50 are 
   will return a valid HTTP 200 response and other IDs will return an error response.
1. Look into the log files of both services and verify that both contain the same
   trace id.
