Hi The hystrix EIP is moved into the master branch. I just added JMX support so you can get the hystrix health stats and whatnot from JMX in the Camel processor tree.
The nice thing is that we can implement other EIPs in the future the same way (eg also a bit like data format today) where we have the EIP in the model in camel-core but have it actually implemented in the component outside camel-core. And the end user should just remember to add the camel-xx component to the classpath. Integration with the dashboard requires to output those metrics in turbine json format that the dashboard uses.
