This training video demonstrates practical DTrace implementation for multithreading scenarios, focusing on variables, the sched provider, function call counting, and thread ID capture. Learn how to develop effective D programs through hands-on examples, starting with an introduction to useful resources before exploring the a.out module, curcpu variable, and sched provider. Understand a sample application's architecture, then master techniques for counting user function calls and capturing Posix thread IDs. Explore thread scheduling statistics, learn when to use aggregations, and work with on-cpu and off-cpu probes. The 36-minute Oracle tutorial provides comprehensive coverage of DTrace methodology with practical examples, serving as the second part of a multithreading module series. Additional free resources are available through Oracle Linux Training Station, Hands-on Labs, YouTube playlists, and official documentation.
