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 statistics data

The framework collects statistics data and provides several statistics data outputs. To augment the statistics data with custom attributes or enable more data sinks, set the appropriate parameter to on.

About this task

Enable custom statistics outputs by setting the appropriate parameter to on.

Procedure

In the file <PathToYourApplication>/config/config.cfg, find the ite.ingest.reader.customFileStatistics parameter description
To enable the custom file statistics, set the parameter to on: ite.ingest.reader.customFileStatistics=on
In the file <PathToYourApplication>/config/config.cfg, find the ite.ingest.reader.customParserStatistics parameter description
To enable the custom parser statistics, set the parameter to on: ite.ingest.reader.customParserStatistics=on
In the file <PathToYourApplication>/config/config.cfg, find the ite.storage.auditOutputs parameter description
To enable an extra processing step for file statistics that you can use to write the statistics to a database or export the statistics to another application, set the parameter to on: ite.storage.auditOutputs=on

You implement the code that is enabled with ite.storage.auditOutputs in the <namespace>.chainsink.custom::AuditTableWriter composite operator.
