Linux administration guides for performance triage, diagnostics, benchmarking, and practical field tooling.
Linux
Linux troubleshooting guides, kernel deep dives, performance playbooks, diagnostics, and practical administration tooling.
Use these pages to troubleshoot Linux systems, understand kernel behavior, and work faster with practical field-tested tooling.
Start here
- Administration for performance triage, diagnostics, benchmarking, and operational tooling
- Kernel for crash dumps, CPU behavior, privilege levels, and kernel troubleshooting concepts
- How to Troubleshoot Linux Performance — Field Playbook for the fastest path from symptom to bottleneck
Featured guides
- How to Troubleshoot Linux Performance — Field Playbook for live triage and intermittent performance investigations
- How to Benchmark Linux with Tux Toaster for controlled load generation across CPU, memory, disk, and network
- How to Analyze Linux sosreport and supportconfig with SOSParser for structured post-collection analysis
- Kernel Mode vs User Mode: Privilege Levels and System Call Execution for a deep technical explanation of execution context and privilege separation
Common tasks
- Diagnose CPU, memory, I/O, or network bottlenecks quickly
- Prepare better data before a production incident disappears
- Understand kernel-level symptoms such as lockups, panics, and crash dumps
- Compare systems before and after kernel, firmware, or workload changes
Kernel
Linux kernel troubleshooting guides, crash dump content, CPU behavior, lockup analysis, and low-level execution concepts.
