init_config:
 
instances:
  # This check is for monitoring and reporting metrics on cf backup
  #
  # WARNING: Ensure the user account running the Agent (typically dd-agent) has read
  # access to the monitored directory and files.
  #
  # Instances take the following parameters:
  # "directory" - string, the directory to monitor. Required
  # "name" - string, backup service name. Required
