Cockpit is perfect for new sysadmins, allowing them to easily perform simple tasks such as storage administration, inspecting journals and starting and stopping services.
Jumping between the terminal and the web tool is no problem. A service started via Cockpit can be stopped via the terminal. Likewise, if an error occurs in the terminal, it can be seen in the Cockpit journal interface.
You can monitor and administer several servers at the same time. Just add them with a single click and your machines will look after its buddies.
Cockpit is under rapid development - do not use it in production environments.
