In this article, I will focus on how Spring Boot Admin can be integrated with microservices supporting Hystrix dashboard. To enable the Hystrix metrics stream, include a dependency on spring-boot-starter-actuator and set management.endpoints.web.exposure.include: hystrix.stream. This allows the REST service to restore itself if it was getting too much traffic. You don’t want users to be stumbling over a page loading very slowly (due to network timeouts) and then arriving on an error page. So, open application.properties (or application.yml) and add the following properties to configure the Eureka location: The way Spring boot + Eureka works is that microservices are registered with their application name. JDK 1.8; Maven 3.5.4; ui-button ui-button Hystrix - Getting Failure Exception In Fallback Spring Boot: Hystrix and ThreadLocals. In this case I’ll just copy the DTO from the microservice itself, called TaskDTO: The service itself will use RestTemplate to make a call to the service using the Ribbon interceptor to look up the hostname through Eureka: Now, before we write our controller, we need a template (using Thymeleaf). Doing so exposes the /actuator/hystrix.stream as a management endpoint, as shown in the following example: Spring Boot Actuator – taking Application's Insights. If you’re seeing this, then it means you successfully managed to make it through this tutorial. For now, let’s add the following method: So, if we run the application again and make it time out again, we’ll see a completely different result. We also have a youtube video on this topic. Let's create a new project for this dashboard. After opening the project it’s time to create a basic application up and running.
