Analyse the boot process with bootchart
Its sunday today. It a blogging day :P.
Most of you already know the bootchart program. But for those who dont , Im gonna show them how to view their system start up procedure.
If you are a gentoo user , first emerge app-benchmark/bootchart
Then, open /etc/bootchartd.conf and edit the following lines
AUTO_RENDER=”yes”
AUTO_RENDER_FORMAT=”png” ( replace png with svg or eps if you want )
AUTO_RENDER_DIR=”/var/log”
These are the default options , but make sure that are configured fine on your machine.
Then, open /boot/grub/grub.conf and add
init=/sbin/bootchartd on kernel options like the example below
title=Gentoo Linux
root (hd0,0)
kernel /boot/vmlinuz-2.6.26-gentoo-r3 root=/dev/sda3 init=/sbin/bootchartd quiet
Reboot your machine , and you will find under /var/log/ and image named bootchart.png picturing your boot process :)
Have a nice day
