systemd-bootchart
Boot performance analysis graphing tool
Description
Systemd-bootchart is an boot time analysis tool. It represents
various aspects of the system as graph elements. These graph
elements allow the user to determine resource usage, efficiency
and performance issues.
Invocation
systemd-bootchart can be invoked in several different ways:
Kernel invocation
The kernel can invoke systemd-bootchart
instead of the init process. In itself, systemd-bootchart
will invoke /sbin/init if invoked in
this matter.
Started as a standalone program
One can execute systemd-bootchart as
normal application from the commandline. In this mode
it is highly recommended to pass the "-r" flag in order
to not graph the time elapsed since boot and before
systemd-bootchart was started, as it may result in
extremely large graphs.
Options
Please read systemd-bootchart --help or the bootchart.conf manual
page for information about the various options that influence how
systemd-bootchart operates.
Output
Systemd-bootchart generates SVG graphs. In order to render these
on a graphica display any SVG capable viewer can be used. It should be
noted that the SVG render engines in most browsers (including Chrome
and Firefox) are many times faster than dedicated graphical applications
like Gimp and Inkscape. Just point your browser at "file:///var/log"!
