How to expose Hystrix Stream on Spring Actuator port? - spring

Question

I am using Jetty embedded server in the Spring Boot application.
To handle requests I provide my custom handler like that.
#Slf4j
#Configuration
#EnableWebMvc
#SpringBootApplication
public class Main {
public static void main(String... args) {
new SpringApplicationBuilder().sources(Main.class).run(args);
}
#Bean
public EmbeddedServletContainerCustomizer customizer(JettyRequestHandler myCustomHandler) throws MalformedURLException {
return new EmbeddedServletContainerCustomizer() {
#Override
public void customize(ConfigurableEmbeddedServletContainer container) {
if (container instanceof JettyEmbeddedServletContainerFactory) {
customizeJetty((JettyEmbeddedServletContainerFactory) container);
}
}
private void customizeJetty(JettyEmbeddedServletContainerFactory jetty) {
jetty.addServerCustomizers((JettyServerCustomizer) server -> {
HandlerCollection handlerCollection = new HandlerCollection();
handlerCollection.setHandlers(new Handler[]{myCustomHandler, server.getHandler()});
server.setHandler(handlerCollection);
});
}
};
}
}
I am listening for a requests on a standard 8080 port. I included also Spring Boot Actuator into my project to get some production endpoints (health, etc.). It starts on another port: 8181.
Additionally I am using Hystrix for circuit breaking purposes.
My question is how to enable Hystrix Stream to be exposed on actuator port?
Currently I managed only to expose it on standard port 8080 with following piece of code:
#Bean
public ServletRegistrationBean hystrixStreamServlet(){
return new ServletRegistrationBean(new HystrixMetricsStreamServlet(), "/hystrix.stream");
}
But I would like to expose it on another, to have the default one only for application purposes.
Those are some of my dependecies:
compile 'com.netflix.hystrix:hystrix-core:1.5.3'
compile 'com.netflix.hystrix:hystrix-metrics-event-stream:1.5.3'
compile 'org.springframework.boot:spring-boot-starter-actuator:1.3.5.RELEASE'
I would like NOT to use Spring Cloud where is #EnableHystrix that gives the stream on the actuator port actually.

Actually I did what #m-deinum proposed and it worked. I used Spring Cloud Stack.
To achieve Hystrix Stream on actuator I added dependecies:
compile group: 'org.springframework.cloud', name: 'spring-cloud-starter', version: '1.1.1.RELEASE' // spring cloud starter
compile group: 'org.springframework.cloud', name: 'spring-cloud-starter-hystrix', version: '1.1.3.RELEASE' // spring cloud hystrix starter
compile group: 'org.springframework.cloud', name: 'spring-cloud-starter-ribbon', version: '1.1.3.RELEASE' // spring ribbon starter
And the annotation on the Main class:
#EnableCircuitBreaker
#SpringBootApplication
public class Main {
public static void main(String... args) {
new SpringApplicationBuilder().sources(Main.class).run(args);
}
// ...
}
