If you are running your applications on a microservices architecture you might want to trace which instances are getting called, how often and which one may have performance issues. In this post we are going to add a distributed tracing to monitor our Quarkus application so we can easily identify which instances are being called. In this post we will see how to log all received requests by adding Jaeger as the Distributed Tracing system of an existing Quarkus application. First we need to add the smallrye-opentracing extension to our project by running the Quarkus add-extension command: Hopefully, you should get a success message printed out in your terminal telling you that your extension has been installed and as usual we now need to import our new maven dependency into the project. The next thing we need to do is configure our application properties file to set, among other things, the name of the service for the Jaeger UI in which all of our logs will be saved to.
