Service configuration

Parameter Default Description
InputChannel* "storage_slap" Channel to be used as input
StorageDir "./storage" Directory containing all the storage files

* inherited from service configuration, mentioned here because it has a different default value

Additionally the storage filesystem service includes all properties of the service configuration and the input configuration.
