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).
|
|
|
|
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.
