| 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. |
