Cribl Stream is an observability pipeline tool living between any data source and any destination. These destinations can be systems of analysis (Splunk, Elastic, etc.) or systems of retention (S3 buckets, Data Lakes, etc.). Stream uses Sources, Destinations, Routes and Pipelines to move data coming from data sources, processes through its pipelines (group of functions) and sends the results to one or many destinations in the format that is best for the environment and its use cases.
