Description
This course introduces DTrace and teaches common performance analysis techniques. It is intended for system support staff, system administrators, developers, and anyone who would like to quickly learn DTrace and some practical methods for applying it. This course teaches core features of DTrace that are available in many enterprise and cloud computing environments, and is taught from a Joyent SmartMachine, a restricted environment that provides these features. Kernel internal analysis is not covered. (An advanced course for kernel-level DTrace is planned in the future.)

- Explain Dynamic Tracing and DTrace
- Describe DTrace features, including probes, providers, actions, aggregations
- Identify opportunities for improving performance using DTrace
- Solve performance issues using workload characterization
- Solve performance issues using latency analysis
- Use DTrace to analyze system calls in custom ways
- Profile CPU usage of user-level applications, identifying hot code paths
