Траблшутинг Linux: как искать проблемы системно

Linux Troubleshooting: How to Systematically Find Problems A systemic troubleshooting methodology for Linux – from the first seconds of an incident to the postmortem. No panic or guesswork: a clear algorithm that helps restore servers when everything breaks. We'll explore real-world scenarios: what to check in the first 5 minutes, how to diagnose a dead server, issues with boot and the kernel, file systems, networking (from L2 to TLS), services, and systemd. We'll cover performance, OOM, configuration drift, and CrashLoop separately. Finally, we'll cover how to write postmortems that truly prevent recurrence. Suitable for DevOps engineers, system administrators, and developers who have basic Linux knowledge but lack a structured approach to troubleshooting.
