1 | PYBOOTCHARTGUI | ||
2 | ---------------- | ||
3 | |||
4 | pybootchartgui is a tool (now included as part of bootchart2) for | ||
5 | visualization and analysis of the GNU/Linux boot process. It renders | ||
6 | the output of the boot-logger tool bootchart (see | ||
7 | http://www.bootchart.org/) to either the screen or files of various | ||
8 | formats. Bootchart collects information about the processes, their | ||
9 | dependencies, and resource consumption during boot of a GNU/Linux | ||
10 | system. The pybootchartgui tools visualizes the process tree and | ||
11 | overall resource utilization. | ||
12 | |||
13 | pybootchartgui is a port of the visualization part of bootchart from | ||
14 | Java to Python and Cairo. | ||
15 | |||
16 | Adapted from the bootchart-documentation: | ||
17 | |||
18 | The CPU and disk statistics are used to render stacked area and line | ||
19 | charts. The process information is used to create a Gantt chart | ||
20 | showing process dependency, states and CPU usage. | ||
21 | |||
22 | A typical boot sequence consists of several hundred processes. Since | ||
23 | it is difficult to visualize such amount of data in a comprehensible | ||
24 | way, tree pruning is utilized. Idle background processes and | ||
25 | short-lived processes are removed. Similar processes running in | ||
26 | parallel are also merged together. | ||
27 | |||
28 | Finally, the performance and dependency charts are rendered as a | ||
29 | single image to either the screen or in PNG, PDF or SVG format. | ||
