In that case you might want to have your Hystrix commands push metrics to Turbine, and Spring Cloud enables that with AMQP messaging. the InstanceInfo for customers has an appName of "CUSTOMERS"). You then visit /hystrix and point the dashboard to an individual instances /hystrix.stream endpoint in a Hystrix client application. The main purpose is to solve a component of service avalanche effect, which is the last line of defense to protect high availability […] You can pass configuration parameters using the -Dconfiguration=value parameter, the available configurations are listened in the table below. You can then point the Hystrix Dashboard to the Turbine AMQP Server instead of individual Hystrix streams. in a PaaS setting), the classic Turbine model of pulling metrics from all the distributed Hystrix commands doesn’t work. ...
