RRDtool definition
RRDtool refers to the round Robin database tool. Round Robin is a technology that deals with quantitative data and current element pointers. Imagine a perimeter marked with a circle--these are the places where time is stored. Draw an arrow from the center of the circle to a point in the circle--that's the pointer. As we are on a circle, there is no starting point or end, you can go down. Over time, all available locations will be used, and the loop will automatically reuse the original location.
