Description

Linux Process Monitoring and Diagnostics using the /proc Interface is a comprehensive course designed for system administrators, developers, and anyone looking to gain a deeper understanding of Linux process management. This course focuses on the /proc filesystem (procfs), an essential interface for monitoring, diagnosing, and analyzing Linux processes and system performance.Throughout the course, you'll learn how to explore and utilize procfs to gather critical process-specific information, including CPU and memory usage, file descriptors, I/O statistics, and thread details. We'll also cover system-wide statistics like CPU load, memory allocation, disk I/O, and network performance, all accessible via the /proc interface.Beyond monitoring, you'll dive into advanced topics like resource limits, scheduler statistics, and how to troubleshoot stuck processes using procfs. Real-time monitoring tools like top, slabtop, htop, ps, lsof, fuser, and many more command-line tools will be integrated into your workflow to give you hands-on experience with dynamic system diagnostics.By the end of the course, you'll have the skills to write custom scripts for process monitoring and diagnostics, automate system monitoring tasks, and interpret complex process data. Whether you're managing servers, debugging applications, or optimizing system performance, this course equips you with essential tools and knowledge for mastering Linux process internals.
