Problems with hystrix-dashboard turbine using FileBasedInstanceDiscovery

Question

I am trying to set up a hystrix-dashboard with turbine. I am not using Eureka and want to use the FileBasedInstanceDiscovery. I am trying to configure this but following the online documentation doesn't seem to work. It always tries to use the Eureka discovery client. I tried excluding the eureka from my pom but then it falls back to another discovery client CommonsInstanceDiscovery

Here is my application.properties:

turbine.aggregator.clusterConf=mycluster
turbine.instanceUrlSuffix.mycluster=8080/hystrix.stream
turbine.FileBasedInstanceDiscovery.filePath=turbine.hostnames.txt
turbine.InstanceMonitor.eventStream.skipLineLogic.enabled=false
InstanceDiscovery.impl=com.netflix.turbine.discovery.FileBasedInstanceDiscovery

Is there another way to do this? Also, for the filePath for my turbine hostnames, where does it start looking? Can I have the file under my resources directory of my jar?

here is my pom file dependencies:

    <java.version>1.8</java.version>
    <spring-cloud.version>Greenwich.SR1</spring-cloud.version>

Some of the documentation is unclear and conflicting for turbine, I think this is because there is the spring-cloud-netflix project and a standalone turbine project. At any rate, if you are building a spring-boot app then this property is not useful:

InstanceDiscovery.impl=com.netflix.turbine.discovery.FileBasedInstanceDiscovery

If you want to change the implementation of InstanceDiscovery it is pretty simple, just create a bean that implements InstanceDiscovery like this:

@Bean
public InstanceDiscovery instanceDiscovery() {
    //choose either one of the provided implementations from spring or
    //create your own
    return new ConfigPropertyBasedDiscovery();
    //return new FileBasedInstanceDiscovery();
}

Make sure you put this in a @Configuration class. I originally had mine just in my SpringBootApplication class but this doesn't allow you to override the default implementation.
