> What I really wanted is a web interface which will just show me EVERYTHING it knows about the system in a form of charts, graphs, so I can just skim through it and check if everything allright visually, without using the shell and each individual command.

For this reason, I've created Lightkeeper: https://github.com/kalaksi/lightkeeper to simplify repetitive tasks and provide an efficient view for monitoring. Also has graphs as a recent addition, but screenshots don't show it. You can also drop to a terminal with a hotkey any time.

Ironically, it works over SSH without any additional daemons.
