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.

It’s a Kodak W820 digital picture frame, showing a graph of real-time temperature data collected from around the house: upstairs and downstairs, garage, outdoors, and even inside the refrigerator. More photos on Flickr, implementation details below… Temperature Sensors Most of my friends probably know that back in 2004, when I was still in college, I built a set of wireless temperature sensors. Each one is an Altoids tin containing a 9V battery, a Dallas 1-wire temperature sensor, PIC microcontroller, and a little 315 MHz AM radio transmitter. I built several of these indoor wireless sensors, plus one outdoor sensor which I built out of PVC pipe.

Detta är inte så knepigt, eller i alla fall inte lika knepigt som att få igång OWFS! Dock är inte RRDtool helt solklart direkt från början, det skiljer sig lite från en traditionell databas.

It follows the same logic and uses the same data sources, archive types and definitions as RRDTool does. RRD4J supports all standard operations on Round Robin Database (RRD) files: CREATE, UPDATE, FETCH, LAST, DUMP, XPORT and GRAPH. RRD4J's API is made for those who are familiar with RRDTool's concepts and logic, but prefer to work with pure java. If you provide the same data to RRDTool and RRD4J, you will get exactly the same results and graphs. RRD4J is made from the scratch and it uses very limited portions of RRDTool's original source code. RRD4J does not use native functions and libraries, has no Runtime.exec() calls and does not require RRDTool to be present.
