About DTrace
DTrace is a command-line dynamic tracing framework for diagnosing kernel and application problems while systems are running. Dynamic tracing observes events in a live system, allowing engineers to investigate behavior without relying only on logs or reproducing an issue in a separate test environment. The evidence describes it as suitable for troubleshooting in production. It does not list supported probes, scripting syntax, or supported operating systems, so those capabilities depend on the DTrace implementation and configuration. Its role is live system and application observability, which requires care because tracing can affect performance and expose operational data. It provides visibility into live system behavior.
