NAME
bootchart2 - collects and analyses data from boot process
DESCRIPTION
bootchart2 is a tool to log the boot process and make a nice graph out of it, to usually see where it takes longer. It consists of three different pieces of software: a shell script, a collector and a visualisation tool. Please also see the manual pages referred to in the SEE ALSO section.
CONFIGURATION
After install simply add these options to your kernel command line, normally in /boot/grub/menu.lst: initcall_debug printk.time=y quiet init=/sbin/bootchartd ... Then after bootup run pybootchartgui to get an interactive chart rendering tool. If you want to chart the initrd, add rdinitrd=/sbin/bootchartd to the kernel command line. To make bootchart2 work best, please ensure your kernel is configured with CONFIG_PROC_EVENTS=y and CONFIG_TASKSTATS=y If you want to start bootchart2 in a dracut (version >= 008) initramfs, you have to change init=/sbin/bootchartd to rdinit=/sbin/bootchartd and regenerate the initramfs with bootchart support with: # dracut -f -a bootchart
