+# Distributed Tracing with OpenTelemetry and Jaeger
+
+In this project I have figured out how we can integrate distributed tracing in a Spring Boot application. 
+We are using OpenTelemetry to export traces to Jaeger.
+
+You can read about this on my website [https://refactorfirst.com](https://refactorfirst.com)
+
+Once you build the application using `mvn clean verify`, You can start the application as two service instances.
+
+Service 1
+```
+java -jar \
+target/Distributed-Service-0.0.1-SNAPSHOT.jar \
+--spring.application.name=Service-1 \
+--server.port=8080
+```
+
+Service 2
+```
+java -jar \
+target/Distributed-Service-0.0.1-SNAPSHOT.jar \
+--spring.application.name=Service-2 \
+--server.port=8090
+```
