13.1. The State of Linux Tools

This book tours the current Linux performance tools, how to use them individually, and how to use them together to solve performance problems. As with every aspect of Linux, these performance tools are constantly evolving, so when investigating a problem, it is always a good idea to review the man page or documentation of a performance tool to determine whether its usage has changed. The fundamental functions of the performance tools rarely change, but new features are commonly added, so it is helpful to review the latest release notes and documentation for a given tool.
