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

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.

I was able to solve this issue for the spring-boot-starter-parent version 2.0.7.RELEASE and spring-cloud-dependencies version Finchley.SR2 by adding below two properties in the application.properties.

management.endpoints.web.exposure.include=*
management.endpoints.web.base-path=/

Hystrix dashboard itself can't be used for monitoring several instances at once. The thing that you need is turbine+dashboard. In a couple of words turbine is an aggregator for several hystrix metrics streams.

Configuration of instance:

management:
  endpoints:
    web:
      exposure:
        include: hystrix.stream, info, health

spring:
  application:
    name: WRITING
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka

The important thing here is to expose hystix.stream actuator. This endpoint will be used by the turbine to read metrics. Also, do not forget to add actuators starter.

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

If you did everything correctly http://localhost:8080/actuator/hystrix.stream endpoint should become available.

Turbine config will look like:

server:
      port: 8888

spring:
  application:
    name: TURBINE

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

turbine:
  appConfig: WRITING,READING
  clusterNameExpression: new String('default')

In appConfig, you should specify service names for monitoring.

After starting turbine localhost:8888/turbine.stream will be available.

You can pass this URL to the dashboard and monitor all data aggregated for hystrix commands of discovered instances.
