This training video demonstrates practical DTrace implementation for multithreading scenarios, covering essential concepts like timestamps, thread IDs, and thread-local variables. Learn how to develop effective D programs through hands-on examples that explore memory management, scope, thread safety, and call order strategies. Follow along with real program execution to connect findings and understand malloc operations for detecting memory leaks and measuring durations. The tutorial includes detailed explanations of associative arrays, aggregations, and timeline analysis techniques. Part of Oracle's DTrace training series, this module provides foundational knowledge for monitoring and debugging multithreaded applications with DTrace.
