Are you building microservices? Do you struggle with observability and with capturing telemetry data between distributed services? This article shows how to quickly and easily introduce OpenTelemetry into a distributed system built on Java with Quarkus. This combination allows you to visualize the interactions between all the microservices within an overall system.
The article introduces the official Quarkus sample application, Quarkus Superheroes, deploys it on the free Developer Sandbox for Red Hat OpenShift, and demonstrates how to collect and visualize telemetry data in order to observe microservices' behavior.
