Toolkits
A toolkit is a set of SPL artifacts, which are organized into a package. Toolkits make SPL or native functions and primitive or composite operators reusable across different applications.

- APIs
  Application programming interfaces (APIs) provide functions that simplify applications development.
- Job configuration overlays
  You can specify or change configuration parameters when you use the submitjob or updateoperators operations. The settings control submission constraints, host constraints and locations, and operator status. Parameters are captured and updated in the configuration JSON file. When you change the values in the job configuration overlay file, the changes override any previously set values.
- Commands
  Teracloud® Streams provides a number of commands you use to perform tasks.
- Operator model
  An operator model is an XML document that describes the basic properties of a primitive operator.
- Streams Processing Language (SPL)
  Streams Processing Language (SPL) is a distributed data flow composition language that is used in Teracloud® Streams. SPL has primitive types, program structures, and definitions that are tailored for streaming data.
- Toolkits
  A toolkit is a set of SPL artifacts, which are organized into a package. Toolkits make SPL or native functions and primitive or composite operators reusable across different applications.
  - Specialized toolkit requirements and restrictions
    Several of the specialized toolkits require RPMs that are not required by the Teracloud® Streams product. There are also toolkit restrictions on some platforms.
  - Toolkits
- SPLDOC markup
  You can use SPLDOC markup in the descriptions associated with the SPL artifacts in a toolkit. The spl-make-doc command generates HTML documentation from the marked up artifacts.

Getting data streams for debugging

When you develop your application with the framework, you need to examine internal data streams to see whether the behavior and the values are as expected. The framework provides several debug outputs that you enable by setting the appropriate parameter to on. The files that contain the debug information are in the debug directory, which is a subdirectory of the configured data directory.

About this task

Enable debug outputs by switching the appropriate parameter to on.

Procedure

In the file <PathToYourApplication>/config/config.cfg, find the ite.businessLogic.group.debug parameter description
To receive information on the commands and data that is processed in the group logic, set the parameter to on: ite.businessLogic.group.debug=on
In the file <PathToYourApplication>/config/config.cfg, find the ite.businessLogic.sink.debug parameter description
To receive information on the storage stage, set the parameter to on: ite.businessLogic.sink.debug=on
In the file <PathToYourApplication>/config/config.cfg, find the ite.businessLogic.transformation.debug parameter description
To receive information on the transformation stage, set the parameter to on: ite.businessLogic.transformation.debug=on
In the file <PathToYourApplication>/config/config.cfg, find the ite.control.debug parameter description
To receive information on the status and status changes of the ITE application, set the parameter to on: ite.control.debug=on
In the file <PathToYourApplication>/config/config.cfg, find the ite.ingest.debug parameter description
To receive information on the file detection, set the parameter to on: ite.ingest.debug=on
In the file <PathToYourApplication>/config/config.cfg, find the ite.ingest.reader.debug parameter description
To receive information on the parsed files, set the parameter to on: ite.ingest.reader.debug=on
