-RRDtool stores rates in amount/second for COUNTER, DERIVE and ABSOLUTE data.
-When you plot the data, you will get on the y axis amount/second which you
-might be tempted to convert to absolute amount volume by multiplying by the
-delta-time between the points. RRDtool plots continuous data, and as such is
-not appropriate for plotting absolute volumes as for example "total bytes"
-sent and received in a router. What you probably want is plot rates that you
-can scale to for example bytes/hour or plot volumes with another tool that
-draws bar-plots, where the delta-time is clear on the plot for each point
-(such that when you read the graph you see for example GB on the y axis,
-days on the x axis and one bar for each day).
