Operating System Data Collection

Overview

The performance testing framework is not the only place to collect information about software operating parameters. This section collects tip on useful operating system commands or tools which may be used. Some command or tools are specific to an operating system or are variations with differing options and outputs. So this section is organized by by tool and by operating system. Feel free to add your favorite methods to this forum, please do not worry about organization since there is no perfect way to arrange this documentation.
