Subject: Systemd-bootchart doesn't generate CPU and Disk usage chart as in busybox bootchart

Hi,

When I use busybox bootchart with sys v init, I am able to get the bootchart png file with CPU and Disk IO usage at the top of the graph. When I tried the same with systemd-bootchart, I can only see the time spent information by various process at start up.

I am using a bootargs with following params.
init=/usr/lib/systemd/systemd-bootchart initcall_debug init=/sbin/init quiet

And after boot up, I am not able to see any svg file under /var/run/log. I have tried to generate the plot using systemd-analyze utility as systemd-analyze plot > bootlog.svg

But the bootlog.svg doesn show the CPU and IO disk usage graph. What am I doing wrong?

Murali Karicheri,
