Accelerated Linux Core Dump Analysis, Second Edition, Revised and Extended
Accelerated Linux Core Dump Analysis, Second Edition, Revised and Extended
Training Course Transcript with GDB and WinDbg Practice Exercises
About the Book
The full transcript of Software Diagnostics Services training. Learn how to analyze Linux process and kernel crashes and hangs, navigate through core memory dump space and diagnose corruption, memory leaks, CPU spikes, blocked threads, deadlocks, wait chains, and much more. This training uses a unique and innovative pattern-oriented diagnostic analysis approach to speed up the learning curve. The training consists of 30 practical step-by-step exercises using GDB and WinDbg debuggers highlighting almost 40 memory analysis patterns diagnosed in 64-bit core memory dumps from x64 and ARM64 platforms. The training also includes source code of modeling applications, a catalog of relevant patterns from Software Diagnostics Institute, and an overview of relevant similarities and differences between Windows and Linux memory dump analysis useful for engineers with Wintel background. In addition to the fully revised x64 Linux process dump analysis exercises using GDB, the second edition now includes x64 Linux kernel core dump analysis using crash tool and ARM64 Linux process dump analysis using WinDbg. The new revised and extended edition includes additional kernel core dump analysis exercises.
