This is from: http://pybootchartgui.googlecode.com/files/pybootchartgui-r124.tar.gz Will modify it to make the build profiling in pictures. Remove the examples since they would not work any more, and they cost much disk space.

PYBOOTCHARTGUI
|
|
----------------
|
|
|
|
pybootchartgui is a tool for visualization and analysis of the
|
|
GNU/Linux boot process. It renders the output of the boot-logger tool
|
|
bootchart (see http://www.bootchart.org/) to either the screen or
|
|
files of various formats. Bootchart collects information about the
|
|
processes, their dependencies, and resource consumption during boot of
|
|
a GNU/Linux system. The pybootchartgui tools visualizes the process
|
|
tree and overall resource utilization.
|
|
|
|
pybootchartgui is a port of the visualization part of bootchart from
|
|
Java to Python and Cairo.
|
|
|
|
Adapted from the bootchart-documentation:
|
|
|
|
The CPU and disk statistics are used to render stacked area and line
|
|
charts. The process information is used to create a Gantt chart
|
|
showing process dependency, states and CPU usage.
|
|
|
|
A typical boot sequence consists of several hundred processes. Since
|
|
it is difficult to visualize such amount of data in a comprehensible
|
|
way, tree pruning is utilized. Idle background processes and
|
|
short-lived processes are removed. Similar processes running in
|
|
parallel are also merged together.
|
|
|
|
Finally, the performance and dependency charts are rendered as a
|
|
single image to either the screen or in PNG, PDF or SVG format.
