Unable to connect to Command Metrix Stream

[yangzii0920]

Hi,

I have an issue on the dashboard statistic page. I could see the graphics once, but not with the new projects I built.

So here are the application (all of them are Spring Boot application): A (port 9000) calls B (port 9001) calls C (port 9002), Hystrix Dashboard application H simply with a @EnableHystrixDashboard annotation. A, B, and C are Rest web service with A and B having @EnableCircuitBreaker annotation.

Functionally A, B, and C work perfectly so it might not be issue with POM. But when I type no matter the /hystrix.stream of A or B or C on H's home page, it shows Unable to connect to Command Metrix Stream on the next page as shown below.

On browser console there are error messages: EventSource's response has a MIME type ("text/plain") that is not "text/event-stream". Aborting the connection.

IDE console looks like this:

2017-05-23 15:23:01.938  INFO 2652 --- [nio-8080-exec-4] ashboardConfiguration$ProxyStreamServlet : Proxy opening connection to: http://localhost:9001/hystrix.stream
2017-05-23 15:23:02.213  WARN 2652 --- [nio-8080-exec-3] ashboardConfiguration$ProxyStreamServlet : Failed opening connection to http://localhost:9001/hystrix.stream : 404 : HTTP/1.1 404

Where could be wrong?

Thanks.

Something (a proxy or virus scanner) is changing the mimetime to text/plain which is causing the problem.

Please learn how to properly format code and logs.

Here's the repo sample: https://gitlab.com/microservice-samples/micro-services-spring-cloud-config/hystrix-circuit-breaker

Any idea?

Thanks
