"systemctl --no-pager -a" for "all loaded units/properties, including dead/empty ones" "systemctl --no-pager list-unit-files" for all units installed in system for the current loaded units/sockets you have systemctl list-units systemctl list-sockets as for the boot timings you have systemd-analyze and "systemd-analyze blame" Overall check the man pages .. there are a lot of interesting things you can do with systemd but it takes some time to get used to ... i am still not comfortable with all the options of journalctl and i am wondering how it will go when i will migrate my servers to centos 7..
