Unable to connect to Command Metric Stream for Hystrix Dashboard with Spring Cloud

Question

I have microservices project with Spring Cloud, the snippet from parent:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.7.RELEASE</version>
</parent>

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Dalston.SR3</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>

All services are running under Eureka server:

All services are running fine. I can call make appropriate calls with Postman and everything works fine.

I have separate service which handles Hystrix dashboard, a snippet from pom:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jetty</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
    </dependency>

Configuration main class:

@SpringBootApplication
@EnableHystrixDashboard
public class DashboardApp {
    public static void main(String[] args) {
        SpringApplication.run(DashboardApp.class, args);
    }
}

and config yaml file:

spring:
  application:
    name: Dashboard

server:
  port: 8000

eureka:
  client:
    fetchRegistry: true
    registerWithEureka: false
    serviceUrl:
      defaultZone: http://localhost:8761/eureka

I have next dashboard looking:

Full stack trace from the console is here. Following is some snippet:

2018-04-12 11:28:25.089 ERROR 15762 --- [qtp295055909-16] ashboardConfiguration$ProxyStreamServlet : Error proxying request: http://localhost:8082/hystrix.stream

....
Caused by: org.eclipse.jetty.io.EofException: null
...
Caused by: java.io.IOException: Broken pipe
...

Service itself is accessible with spring actuator:

snippet from it's pom:

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-eureka</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-hystrix</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>

Config class looks:

@EnableHystrix
@EnableEurekaClient
@SpringBootApplication
public class TableApp {
    public static void main(String[] args) {
        SpringApplication.run(TableApp.class, args);
    }
}

How to solve this issue?

Answer 1

For those who are using spring boot 2, the hystrix.stream endpoint has been moved to /actuator/hystrix.stream.

For me this url worked:

http://localhost:8082/actuator/hystrix.stream

And yes, have this actuator endpoint enabled via following property:

management.endpoints.web.exposure.include=hystrix.stream

Of course you must have the actutator dependency included in your project.
