[1] The systemd supporters would be keenly wise if they added pytimechart to Gentoo, so those (systemd) reticent to change, can actually see just how wonderful systemd is Here in slide (26) we see "intel" extolling systemd. If Intel thinks systemd is wonderful, then it must be wonderful. (?) [2] as shown in the paper "Elcell_tardy.pdf". PyTimeChart is also wonderful in that it provides a graphical way to spot problems quickly. Most major (linux) distros have both PyTimeChart and Ftrace/trace-cmd/KernelShark. Together folks use PyTimeChart to monitor and identify low-level or low-level-application-interaction problems, and then use Ftrace/trace-cmd/KernelShark for fine grain filtering, collection and analysis of those low-level-application-interaction issues. I have not opened a bug requesting PyTimeChart. hth, James [1] https://pythonhosted.org/pytimechart/index.html [2] elinux.org/images/6/63/Elce11_tardy.pdf
