Datadog Distributed Tracing is a solution that helps organizations manage tracing costs and gain real-time visibility into application performance. It offers fine-grained ingestion controls, tag-based retention filters, live search, and live analytics to troubleshoot issues in distributed systems, serverless computing, and containerized environments. With Datadog Distributed Tracing, teams can control the cost of tracing by adjusting the trace volume and sampling rate per service based on their criteria. The solution also enables real-time investigation of every ingested span by any tag over a rolling 15-minute window, allowing for quick identification of issues such as application outages or unresponsive services. Additionally, Datadog Distributed Tracing provides long-term analysis capabilities through retention filters, which can capture critical performance telemetry and business context for up to 15 days. The solution helps teams pinpoint the source of customer-reported issues with live search, determine how widespread an issue is with live analytics, retain only the traces that are important to their business, and enjoy flexible and controllable tracing.
