RRDtool - Computing amount of data transfered RRDtool stores rates during time intervals. Sometimes you do not want to know the rate (how many bytes per second), you just want to know the total amount of bytes. This can be done, no problem. Please make sure you understand how RRDtool normalizes and consolidates its data. This is explained on my RRDtool - Rates, normalizing and consolidating page. That page already covers most of what you need to know about this subject. You are expected to know its contents in order to understand this page. in Computers > Linuxwith computingdatagraphsrrdrrdtooltricks
