Tuning Prerequisites for Linux layers

Brendan D. Gregg maintains a blueprint for Linux performance tuning tools, Linux performance Tools, with the appropriate analysis tools for each component of the Linux system at a glance.

This page links to various Linux performance material I ' ve created, including the tools maps on the right. These show:linux observability tools, Linux benchmarking Tools, Linux tuning tools, and Linux SAR. For more diagrams, see my slide decks below.

Tools

• Perf_events:perf one-liners, examples, visualizations.
• Perf-tools:perf analysis tools using Perf_events and Ftrace (GitHub).
• Ktap:one-liners, examples, and scripts.
• Flame graphs:using perf, SystemTap, and Ktap.
