Hystrix stream (/hystrix.stream) is only enabled if you have spring boot actuator dependency. Please try to add the below dependency into your pom or gradle build file.

org.springframework.boot:spring-boot-starter-actuator

If your application is not based on spring boot, you need to configure HystrixMetricsStreamServlet by yourself. Because /hystrix.stream is auto-configured by spring cloud netflix and it is based on spring boot.

First, you need to add dependency of com.netflix.hystrix:hystrix-metrics-event-stream into your application. Second, you should HystrixMetricsStreamServlet servlet into web.xml like below.

 <servlet>
    <description></description>
    <display-name>HystrixMetricsStreamServlet</display-name>
    <servlet-name>HystrixMetricsStreamServlet</servlet-name>
    <servlet-class>com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>HystrixMetricsStreamServlet</servlet-name>
    <url-pattern>/hystrix.stream</url-pattern>
</servlet-mapping

  • If I place spring-boot-starter-actuator in my pom.xml my project artifact is going to fail. FYI: My application is in Spring MVC. No boot dependencies. So I have added spring-boot-starter-web, then also I'm getting issue while running the code. – RamaKrishna Ankireddy Jun 22 '17 at 18:24
  • I've updated my answer because you are not using spring-boot. – yongsung.yoon Jun 26 '17 at 06:03
