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.
