How to activate /turbine.stream endpoint in a standalone Turbine application - spring

Question

I am trying to create a standalone application to collect Hystrix stream from other applications. But it does not expose the /turbine.stream endpoint by default. I am sure what is missing in my project.
Spring Boot: 2.0.4.RELEASE, Spring Cloud: Finchley.SR1
The application class:
#SpringBootApplication
#EnableDiscoveryClient
#EnableTurbine
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
The content of applicaiton.yml:
server:
port: 8383
spring:
application:
name: hystrix-turbine
management:
endpoints:
web.exposure.include: '*'
applications: hystrix
turbine:
aggregator:
clusterConfig: ${applications}
appConfig: ${applications}
# instanceUrlSuffix.default: actuator/hystrix.stream
And the maven dependencies:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-turbine</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
I created a sample project for this.

I'd suggest you check the configuration steps below:
1) Your stream URL in the Hystrix Dashboard should be:
http://localhost:{turbine app port}/turbine.stream?cluster={configured cluster in properties file}
The url should be pointing to the port of the application that has #EnableTurbine annotation in your main class.
2) Check if you are getting a response for:
http://localhost:{client app port}/actuator/hystrix.stream
(use your browser for this) (this should be coming from the application you have enabled hystrix on using #EnableCircuitBreaker)
If you're getting pings, then atleast your hystrix stream is accessible. If not, Check if you have: org.springframework.boot:spring-boot-starter-actuator in your client side dependencies and
make sure you have the below property set in application.properties file of the application that has #EnableCircuitBreaker in the main class:
management.endpoints.web.exposure.include= hystrix.stream, info, health
Check the URL again.
3) Once your get a reponse from hystrix.stream, you can now configure your cluster on the turbine app properties file:
turbine:
appConfig: {serviceId in lower case}
aggregator:
clusterConfig: {above serviceId in upper case}
after running the app, check if you've configured the cluster correctly:
http://localhost:{turbine app port}/clusters
you should'nt be getting a "[]" on your browser if all's well.
Once you see a response on the clusters endpoint, you will now be able to see the details on the dashboard when you point it to the turbine app
