Name

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:

The kernel can invoke systemd-bootchart instead of the init process. In itself, systemd-bootchart will invoke /sbin/init if invoked in this matter.

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"!
