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 /etc/bootchartd.conf /etc/dracut.conf.d/bootchartd.conf /lib/bootchart /lib/bootchart/bootchart-collector /lib/bootchart/tmpfs /lib/systemd/system/bootchart-done.service /lib/systemd/system/bootchart-done.timer /lib/systemd/system/bootchart.service /sbin/bootchartd <snip>

[ how to use ]

- configuration file

/etc/bootchart.conf ( no need to edit )

# Tarball for the various boot log files BOOTLOG_DEST=/var/log/bootchart.tgz # 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. AUTO_RENDER="yes" # Image format to use for the auto-generated boot chart # (choose between png, svg and eps). AUTO_RENDER_FORMAT="png" # Output directory for auto-generated boot charts AUTO_RENDER_DIR="/var/log"

- edit grub.cfg

add writable permission

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

add “init=/sbin/bootchard” in grub.cfg

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
