From 3d78bc19c5b63541fd45dad7580ade55ba512764 Mon Sep 17 00:00:00 2001 From: Robert Yang Date: Wed, 6 Jun 2012 13:52:43 +0800 Subject: pybootchartgui: add the original code This is from: http://pybootchartgui.googlecode.com/files/pybootchartgui-r124.tar.gz Will modify it to make the build profiling in pictures. Remove the examples since they would not work any more, and they cost much disk space.

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. + + +To get help for pybootchartgui, run + +$ pybootchartgui --help + + +http://code.google.com/p/pybootchartgui/ -- cgit v1.2.3-54-g00ecf
