Highlights

"Disk Full" at 3 AM. OOM Killer striking in production. I/O bottleneck tanking your app.

Every command in here I've actually typed on a customer's terminal.

WHO THIS IS FOR:

- DevOps and platform engineers automating infrastructure
- Cloud engineers running Linux workloads at scale
- Anyone who maintains Linux as part of their job
- Hobbyists running home labs and self-hosted services
- People returning to Linux work after years on other stacks

WHAT'S INSIDE:

- Disk & Partition Management
- LVM Complete Reference
- Filesystem Operations
- Advanced Storage
- Performance Analysis Framework
- CPU Analysis
- Memory Analysis
- Disk I/O Analysis
- Advanced Diagnostic Tools
- TuneD & Resource Limits
- Troubleshooting Playbooks
- Bonus: Performance Tuning Checklist

HOW YOU'LL USE IT:

- Chapter 2 (LVM) and Chapter 3 (Filesystems) give you the full storage stack from partition to mount
- Chapter 5 (Performance Analysis Framework) starts every investigation with a 60-second triage
- Use Chapter 6-8 (CPU / Memory / Disk I/O) when you already know which resource is the bottleneck
- Chapter 11 (Troubleshooting Playbooks) gives you step-by-step reactions for disk-full, OOM, and I/O saturation
- Chapter 12 (Bonus Tuning Checklist) is designed to be applied to a fresh server in one session

WHY THIS GUIDE:

- Written from production notes, not documentation rewrites — every command has been typed on a real server under pressure
- Structured for lookup, not cover-to-cover reading — open it when something breaks, find the answer in under a minute
- Tested on RHEL, Rocky, AlmaLinux, and Oracle Linux — not a single-distro screenshot guide
