  +== Bus Endpoints
  +
  +Spring Cloud Bus provides two endpoints, `/actuator/bus-refresh` and `/actuator/bus-env`
  +that correspond to individual actuator endpoints in Spring Cloud Commons,
  +`/actuator/refresh` and `/actuator/env` respectively.
  +
  +=== Bus Refresh Endpoint
  +The `/actuator/bus-refresh` endpoint clears the `RefreshScope` cache and rebinds
  +`@ConfigurationProperties`. See the <<refresh-scope,Refresh Scope>> documentation for
  +more information.
  +
  +To expose the `/actuator/bus-refresh` endpoint, you need to add following configuration to your
  +application:
  +
  +[source,properties]
  +----
  +management.endpoints.web.exposure.include=bus-refresh
  +----
  +
  +=== Bus Env Endpoint
  +The `/actuator/bus-env` endpoint updates each instances environment with the specified
  +key/value pair across multiple instances.
  +
  +To expose the `/actuator/bus-env` endpoint, you need to add following configuration to your
  +application:
  +
  +[source,properties]
  +----
  +management.endpoints.web.exposure.include=bus-env
  +----
  +
  +The `/actuator/bus-env` endpoint accepts `POST` requests with the following shape:
  +
  +[source,json]
  +----
  +{
  +	"name": "key1",
  +	"value": "value1"
  +}
  +----
  +
   == Addressing an Instance
   
   Each instance of the application has a service ID, whose value can be set with
  
positive.code: `spring.application.index`, `local.server.port`, `server.port`, or `0` (in that order).
  * `id` is the `vcap.application.instance_id`, if it exists, or a random value.
  
  The HTTP endpoints accept a "`destination`" parameter, such as
  `/bus/refresh?destination=customers:9000`, where `destination` is a service ID. If the ID
  is owned by an instance on the bus, it processes the message, and all other instances
  ignore it.
  
  
negative.code: 
  The "`destination`" parameter is used in a Spring `PathMatcher` (with the path separator
  as a colon -- `:`) to determine if an instance processes the message. Using the example
  from earlier, `/bus-env/customers:**` targets all instances of the
  "`customers`" service regardless of the rest of the service ID.
  
  == Service ID Must Be Unique
