### Distributed Tracing Java Sample

This project demonstrates how to implement distributed tracing in java spring boot application with the help for below microservices

- [order-service](order-service)

- [payment-service](payment-service)

- [user-service](user-service)

### Tracing flow

### Running the code

This application require Eureka service registry

```

cd discovery-server

mvn clean install -Dmaven.test.skip

docker build -t discovery-service:1.0.1 .

docker run -d --name discovery-service -p 8761:8761 discovery-service:1.0.1

```

Run `http://localhost:8761`

![Eureka](eureka.png)

Start individual microservice using below commands

1. UserService

```

cd user-service

mvn clean install -Dmaven.test.skip

sh ./script/start.sh

```

2. OrderService

```

cd order-service

mvn clean install -Dmaven.test.skip

sh ./script/start.sh

```

3. PaymentService

```

cd payment-service

mvn clean install -Dmaven.test.skip

sh ./script/start.sh

```

4. Demo UI

To capture traces from above microservice run the [sample-ui](ui) application using below commands

```

npm install -g serve

serve -l 9090 ui

```

Open http://localhost:9090 and perform actions that will capture traces to signoz
