Q:

Monitor linux server and/or log files using the terminal

Sometime ago when I was first configuring a linux server with Rails I found a nice linux monitor from the terminal. It had percentages and text-based bars showing up. It had a nice text-graphics interface. But I thought: "I will come back to it once I finish the app". So now I finished the app and can't remember in what server I installed it and what tool it was.
Is there a nice linux server monitor open source software that displays live data through the terminal? With colors and bars?
