Bootchart provides a shell script to be run by the kernel in the init phase.
The script will run in background and collect process information, CPU
statistics and disk usage statistics from the /proc file system.
The performance data are stored in memory and are written to disk once the
boot process completes.
The boot log file is later processed using a Java application which builds
the process tree and renders a performance chart in different formats (png,
svg, eps).
This requires apache-ant, and you need the jdk package from /extra installed.
After installation, to run bootchartd;
a) if you run a huge kernel or custom kernel without initrd:
append the following boot option:
init=/sbin/bootchartd
b) If you run a kernel using initrd:
Run the script mkchartd with proper options and append to lilo
configuration file a new entry for bootchart specifying:
initrd /boot/initrd.chart.gz
Remember to run lilo after applying changes.
