pybootchartgui: Import pybootchartgui 0.14.5
This update the pybootchartgui code to the latest release from its new
location at "https://github.com/mmeeks/bootchart". This only imports
the relevant parts, and not all of bootchart2.

1 | PYBOOTCHARTGUI | ||
2 | ---------------- | ||
3 | |||
4 | pybootchartgui is a tool for visualization and analysis of the | ||
5 | GNU/Linux boot process. It renders the output of the boot-logger tool | ||
6 | bootchart (see http://www.bootchart.org/) to either the screen or | ||
7 | files of various formats. Bootchart collects information about the | ||
8 | processes, their dependencies, and resource consumption during boot of | ||
9 | a GNU/Linux system. The pybootchartgui tools visualizes the process | ||
10 | tree and overall resource utilization. | ||
11 | |||
12 | pybootchartgui is a port of the visualization part of bootchart from | ||
13 | Java to Python and Cairo. | ||
14 | |||
15 | Adapted from the bootchart-documentation: | ||
16 | |||
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. | ||
