В кластер входят документы, посвященные механизмам работы процессов Linux и инструментам их анализа, но не входят документы о диагностике зависаний ОС, вызванных сторонними драйверами.
Общие признаки: взаимодействие процессов с ядром Linux, инструменты системного мониторинга и отладки, анализ состояний и жизненного цикла процессов, использование файловой системы /proc
Группа выше: Ядро Linux и его механизмы
Смысл: The main idea is to demonstrate how the /proc file system can be used as a powerful, non-intrusive diagnostic tool to uncover the root cause of process hangs in the Linux kernel, especially when standard debugging tools like strace fail.
A technical guide on using /proc/PID/stack and /proc/PID/syscall to diagnose and resolve unresponsive Linux processes stuck in kernel-level operations like NFS.
Смысл: The main idea is that strace is an indispensable tool for Linux system administrators when standard debugging fails, as it allows them to see exactly how a process interacts with the kernel to find the root cause of errors.
A practical guide demonstrating how to use strace to diagnose memory allocation failures, file descriptor limits, and session-level database configuration issues in Linux.
Смысл: The main idea is to educate the reader on how to interpret system monitoring tools like htop by explaining the underlying Linux kernel mechanisms, the /proc filesystem, and process lifecycle management.
A detailed guide explaining htop metrics, Linux process states, memory management, and system daemon optimization through practical examples and kernel insights.
Смысл: The main idea is to educate beginners in system programming on the internal mechanics of Linux processes, specifically how they are created, transitioned through various operational states, and eventually cleaned up by the kernel.
An educational guide explaining the lifecycle of Linux processes, from creation via fork() and program replacement via exec() to termination and zombie states.
