Splunk® Data Stream Processor

Function Reference

On April 3, 2023, Splunk Data Stream Processor reached its end of sale, and will reach its end of life on February 28, 2025. If you are an existing DSP customer, please reach out to your account team for more information.

All DSP releases prior to DSP 1.4.0 use Gravity, a Kubernetes orchestrator, which has been announced end-of-life. We have replaced Gravity with an alternative component in DSP 1.4.0. Therefore, we will no longer provide support for versions of DSP prior to DSP 1.4.0 after July 1, 2023. We advise all of our customers to upgrade to DSP 1.4.0 in order to continue to receive full product support from Splunk.

Configuring functions in DSP pipelines

As a user, you can route and process data in motion by building data pipelines that define how to move the data and how to transform it along the way. Each data pipeline is made up of multiple functions, and each function performs a specific action for the pipeline, such as reading data from a particular data source or changing the format of the data. To build a pipeline, add functions as specific points of the pipeline and configure each function to act on the data as you need it to. You can build a pipeline using the Canvas View or the SPL View. The supports Search Processing Language, version 2 (SPL2), that you use to build and modify pipelines.

Consult this Function Reference manual for information about all the DSP functions that you can use in your pipelines. To see the details about a given function, such as the supported parameters and examples of how to configure the function using SPL2, refer to the documentation page for that function.
