Using Linux Performance Tools

Move from basic Linux administration to advanced in this course that details how to monitor, profile, and trace Linux systems and applications. Linux expert Sasha Goldshtein shows you how to run basic performance checklists to get a reading of high-level system performance. You'll discover ways to diagnose specific issues such as high CPU load, excessive I/O, and slow network requests; as well as gain a solid understanding of the Linux system infrastructure that makes tracing and profiling possible. The course is designed for application developers, system administrators, and SREs with some Linux system administration experience and a basic understanding of OS concepts like threads, I/O operations, and memory.

• Master the ability to identify overloaded resources on a Linux system
• Learn about the Utilization Saturation and Errors (USE) methodology for performance investigation
• Explore Linux performance information sources such as kprobes and uprobes
• Understand how to improve CPU utilization by doing careful profiling and identifying bottlenecks
• Gain the ability to visualize stack reports using flame graphs
• Learn about tracing I/O, scheduling, and other system events using ftrace and perf tools
• Discover methods for analyzing CPU performance at the process, module, and function level
• Understand how to trace slow disk accesses and file system operations
