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
