The accumulated log file may later be visualized using \fBbootchart(1)\fP. .PP \fBbootchartd\fP is commonly used to profile the boot process for the purpose of speeding it up. In this case, it is started by the kernel as the init process. This is configured by adding the \fBinit=/sbin/bootchartd\fP option to the kernel command line -- either interactively or by editing the bootloader's configuration file. Please refer to the documentation of your bootloader for details (e.g. lilo, grub or yaboot). .PP After \fBbootchartd\fP is initialized during the boot process, it will start the default init process (\fI/sbin/init\fP) to proceed with the regular bootup. If, however, an alternative init process is used (e.g. (\fI/sbin/initng\fP), that process may be specified using the \fBbootchart_init=\fIINIT\fP kernel command line parameter. .PP Another possibility for using \fBbootchartd\fP is monitoring the resource usage of a specific application or the running system in general. In this case, bootchartd is started interactively by running \fBbootchartd start\fP and stopped using \fBbootchartd stop\fP. .SH FILES .TP /var/log/bootchartd.tgz default output file .TP /etc/bootchartd.conf default configuration file .SH SEE ALSO .BR bootchart(1), .BR bootchartd.conf(5) .SH AUTHOR bootchart was written by Ziga Mahkovec . .PP This manual page was written by J\[:o]rg Sommer , for the Debian project (but may be used by others).
