PYBOOTCHARTGUI
----------------

pybootchartgui is a tool (now included as part of bootchart2) 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.
