One more question – when the circuit is open due to an issue in the following service call, how long it is kept open before the hystrix tries again to see if the service is working or not. Is there a setting to control it?

Did you try to send some test requests to the service?

Hi Piotr

When I try this url, i keep getting ping: in the browser, nothing else.

In the logs i see –
Mapped “{[/hystrix.stream/**]}” onto public org.springframework.web.servlet.ModelAndView org.springframework.cloud.netflix.endpoint.ServletWrappingEndpoint.handle(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse) throws java.lang.Exception

Hi Shaan,
Did you check out the application logs just after startup if hystrix.stream is available for the application? Did you try to download that file just by calling this URL http://localhost:3333/hystrix.stream from your web browser?

I have done the set up as explained in the article above, but i am getting following error when i use the hystrix dashboard to monitor hystrix stream – http://localhost:3333/hystrix.stream
Any help would be greatly appreciated.
