lost and found ( for me ? )

Fedora 16 : bootchart ( visualize boot sequences )

bootchart visualizes boot sequences.

[ install ]

# cat /etc/fedora-release
Fedora release 16 (Verne)

# uname -ri
3.2.7-1.fc16.x86_64 x86_64

You can install it via yum
# yum search bootchart

bootchart and bootchart-daemon packages will be installed.
# rpm -ql bootchart-daemon

[ how to use ]

- configuration file

/etc/bootchart.conf ( no need to edit )
# Tarball for the various boot log files

# Whether to automatically generate the boot chart once the boot logger
# completes.  The boot chart will be generated in $AUTO_RENDER_DIR.
# Note that the bootchart package must be installed.

# Image format to use for the auto-generated boot chart
# (choose between png, svg and eps).

# Output directory for auto-generated boot charts

- edit grub.cfg

add writable permission
[root@fc16 ~]# chmod u+w /boot/grub2/grub.cfg

add “init=/sbin/bootchard” in grub.cfg
    39 menuentry 'Fedora Linux, with bootchartd' --class fedora --class gnu-lin     39 ux --class gnu --class os {

    50         initrd  /boot/initramfs-3.2.7-1.fc16.x86_64.img
    51 }

I added the new boot lines for bootchartd.
please take care of editing grub.cfg.

reboot the OS
# reboot

check the boot options.
# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.2.7-1.fc16.x86_64 root=UUID=61b367fb-2790-407f-a071-262e8b857fb9 ro rd.md=0 rd.lvm=0 rd.dm=0 quiet rhgb rd.luks=0 LANG=ja_JP.UTF-8 KEYTABLE=jp106 reboot=b,a init=/sbin/bootchartd

bootchard logs are stored under /var/log directory.
[root@fc16 ~]# ls /var/log/bootchart.*
/var/log/bootchart.png  /var/log/bootchart.tgz
