  (_where, `org.springframework.integration` is the global package for everything Spring Integration related, 
  which is responsible for messaging channels_)
  
  These properties can also be specified via `deployment` properties when deploying the stream.

  == Logging
  
  Spring Cloud Data Flow is built upon several Spring projects, but ultimately the dataflow-server is a
  Spring Boot app, so the logging techniques that apply to any link:http://docs.spring.io/spring-boot/docs/current/reference/html/howto-logging.html#howto-logging[Spring Boot]
  application are applicable here as well.
  
  
  While troubleshooting, following are the two primary areas where enabling the DEBUG logs could be
  useful.
  
  === Deployment Logs
  Spring Cloud Data Flow builds upon link:https://github.com/spring-cloud/spring-cloud-deployer[Spring Cloud Deployer] SPI
  and the platform specific dataflow-server uses the respective link:https://github.com/spring-cloud?utf8=%E2%9C%93&query=deployer[SPI implementations].
  Specifically, if we were to troubleshoot deployment specific issues; such as the network errors, it'd
  be useful to enable the DEBUG logs at the underlying deployer and the libraries used by it.
  
  . For instance, if you'd like to enable DEBUG logs for the link:https://github.com/spring-cloud/spring-cloud-deployer-local[local-deployer], 
  you'd be starting the server with following.
