pybootchartgui: Import pybootchartgui 0.14.5
This update the pybootchartgui code to the latest release from its new
location at "https://github.com/mmeeks/bootchart". This only imports
the relevant parts, and not all of bootchart2.

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 + +This code was originally hosted at: + http://code.google.com/p/pybootchartgui/ |
