- PYBOOTCHARTGUI
- ----------------
-
-pybootchartgui is a tool 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.
