The Cockpit Management Console In Fedora 21 Makes Linux Administration Easy

Cockpit also supports viewing systemd targets, sockets, timers, and paths.

Of course, the systemd journal also comes into play with being able to view the errors/warnings/notices from this web-based interface.

Various networking information can be analyzed via Cockpit.

Storage information is also shown -- including the disks, sizes, and storage journal. It's also possible to even create a RAID device and LVMs via this web interface.

Creating new accounts is also possible for the system.
