Bootchart

Bootchart is a tool for performance analysis and visualization of the Linux boot process. Resource utilization and process information are collected during the user-space portion of the boot process and are later rendered in a PNG, SVG or EPS encoded chart. For embedded systems several developers have tried to use bootchart to analyze boot time, but problems arose. There have been several efforts to modify bootchart to make it more useful for embedded development.
