|  | 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. |
