I already have the data; charting is the missing piece. I use live data daily in my work; so does every other system administrator in the world. top, vmstat, iostat, etc. are all live(ish) data, very useful to have access to, and useful to plug into a GUI. It is not opening a portal to another dimension, or something, it's just looking at the state of a thing as it is right now and printing it out. I'm sure there are many other areas where a live view is valuable in a user interface (stock prices, exchange rates, temperatures, etc.). There are all sorts of metrics that aren't necessarily well-served by live data, but existence of those does not negate the existence of metrics that are useful to have as they happen.
