Detailed "bootchart --help"....


I have posted this thread because I am trying to find out the syntax of the "bootchart" command. How is it used, and how do you create bootcharts?

When bootchart is installed, it includes a daemon in /sbin/bootchartd that gathers the statistics. This needs to be loaded at boot time by changing the grub kernel line. It creates a file that contains the statistics, which bootchart uses to generate an image file:

1. When Ubuntu boots, press 'escape' to see the grub menu.
2. Press 'e' to edit the menu (just a temporary change for this boot).
3. Select the kernel line and add 'init=/sbin/bootchartd'
4. Press 'b' to continue the boot.

Once it has booted, the file bootchart.tgz will appear in /var/log. You can then just run bootchart from the user account, and it will generate an image file (typically .png or .svg) in the current directory; you don't need to set any options. This image file can be viewed using your favorite image viewer.
