Eureka Server - list all registered instances

Question

I have a Spring Boot application that is also a Eureka Server. I want to list all instances that have been registered to this Eureka Server. How do I do it?

Answer 1

Fetch the registry using EurekaServerContextHolder.getInstance().getServerContext().getRegistry() then use the registry to list all Applications

PeerAwareInstanceRegistry registry = EurekaServerContextHolder.getInstance().getServerContext().getRegistry();
    Applications applications = registry.getApplications();

    applications.getRegisteredApplications().forEach((registeredApplication) -> {
        registeredApplication.getInstances().forEach((instance) -> {
            System.out.println(instance.getAppName() + " (" + instance.getInstanceId() + ") ");
        });
    });
