On April 3, 2023, Splunk Data Stream Processor will reach 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 before July 1, 2023 in order to continue to receive full product support from Splunk.

Get data from Splunk DSP Firehose

Use the Splunk DSP Firehose to get data sent from the Forwarder, Collect, Ingest, DSP HEC, and Syslog (through SC4S) API services. These services support data ingest for the following data sources:

  • Splunk forwarders
  • HTTP clients
  • Syslog data
  • The Ingest REST API

The Splunk DSP Firehose collects data from all of the supported services concurrently and outputs the combined data in a single stream, allowing you to ingest data from multiple data sources at the same time with minimal pipeline configuration. See Connecting multiple data sources to your DSP pipeline in the Connect to Data Sources and Destinations with DSP manual for more information.
