This technical report discusses the emergence and significance of telemetry pipelines in managing the increasing volume of telemetry data generated by modern distributed systems. It outlines the challenges organizations face in efficiently collecting, processing, and analyzing this data while balancing costs and complexity. The report defines telemetry pipelines as systems that manage the lifecycle of telemetry data, including collection, transformation, enrichment, and routing to various tools. It emphasizes the importance of these pipelines in enhancing operational performance, reducing costs, and improving security and compliance. The document also compares telemetry pipelines with traditional observability pipelines, highlighting their broader capabilities and flexibility. Furthermore, it presents real-world outcomes and return on investment associated with implementing telemetry pipelines, such as improved incident response times and significant cost reductions in observability tools. Overall, the report illustrates how telemetry pipelines can transform observability from a reactive to a proactive strategy, ultimately benefiting various business functions.
