Spring Boot Turbine | 易学教程

问题

I tried turbine + hystrix dashboard with Spring boot 2. But i get problem, turbine dashboard only shows :
Loading ...
I have working Eureka server and application (sends proper hystrix.stream)
When i look at turbine.stream its only

: ping
data: {"reportingHostsLast10Seconds":0,"name":"meta","type":"meta","timestamp":1533038381277}

I was looking in many questions but i cant get answer.

This is turbine pom file:

@janusz Please attach a screenshot of your dashboard for more clarity.

If you're seeing this on your screen:

It could mean:

You need to hit the endpoint that contains the @HystrixCommand annotated function (in your case I'm assuming it is RANDOMNUMBERSERVICE app's endpoint) in order to create data for the dashboard to display.
You have no running instance of serviceId RANDOMNUMBERSERVICE
Check if your clusters are correctly configured: http://localhost:9090/clusters should NOT return [] on your browser.

If you're seeing this on your screen:

Check if your clusters are correctly configured: http://localhost:9090/clusters should NOT return [] on your browser. Normally this issue is due to inability to access /hystrix.steam from the configured instances but you have stated that that you are already receiving the stream.

I'd suggest using the below in your application.properties file could recify this:

turbine.appConfig = randomnumberservice
turbine.aggregator.clusterConfig = RANDOMNUMBERSERVICE

Finally, make sure the URL you're entering for turbine enabled dahboard is pointing to the port that your dashboard is on. in your case it should be:

http://localhost:9090/turbine.stream?cluster=yourclustername
