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.
