# Log Tracing with Spring Cloud Sleuth
This project shows how to implement tracing in a network of Spring Boot applications.
## Companion Blog Article
The companion blog article to this repository can be found [here](https://reflectoring.io/tracing-with-spring-cloud-sleuth/).
## Getting Started
This application is a service facing the user (a "downstream" service), meaning that
it accesses other upstream services to provide its functionality.
1. Start the [upstream service](../sleuth-upstream-service/) with `./gradlew bootrun`
1. Start this 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.

# Tracing with Spring Cloud Sleuth, OpenTelemetry and Logz.io
- run `./mvnw clean install` to build the two Spring Boot applications (`api-service` and `customer-service`)
- run `LOGZIO_REGION=<YOUR_LOGZIO_REGION> LOGZIO_TRACES_TOKEN=<YOUR_LOGZIO_TRACING_TOKEN> docker-compose up --build`
- call `http://localhost:8080/customers/<ID>` (where ID is a number from 1 to 50)
The above HTTP call goes to the `api-service`, which will call the `customer-service` for additional information. This will create a trace across both services, as should be evident in the logs with the same trace id.
The `docker-compose` command also starts up an OpenTelemetry Collector, to which the Spring Boot apps send their traces. The OpenTelemetry Collector, in turn, sends the traces to Logz.io.
