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.
