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
  • Amazon CloudWatch
  • Amazon S3
  • Amazon Web Services (AWS) metadata
  • Google Cloud Monitoring
  • Microsoft 365
  • Microsoft Azure Monitor

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.
