1 PYBOOTCHARTGUI
2 ----------------

4pybootchartgui is a tool for visualization and analysis of the
5GNU/Linux boot process. It renders the output of the boot-logger tool
6bootchart (see http://www.bootchart.org/) to either the screen or
7files of various formats. Bootchart collects information about the
8processes, their dependencies, and resource consumption during boot of
9a GNU/Linux system. The pybootchartgui tools visualizes the process
10tree and overall resource utilization.

12pybootchartgui is a port of the visualization part of bootchart from
13Java to Python and Cairo.

15Adapted from the bootchart-documentation:

17 The CPU and disk statistics are used to render stacked area and line
18 charts. The process information is used to create a Gantt chart
19 showing process dependency, states and CPU usage.
20
21 A typical boot sequence consists of several hundred processes. Since
22 it is difficult to visualize such amount of data in a comprehensible
23 way, tree pruning is utilized. Idle background processes and
24 short-lived processes are removed. Similar processes running in
25 parallel are also merged together.
26
27 Finally, the performance and dependency charts are rendered as a
28 single image to either the screen or in PNG, PDF or SVG format.
