/**
* RRD4J is a high performance data logging and graphing system for time series data, implementing
* RRDTool's functionality in Java. It follows much of the same logic and uses the same data sources,
* archive types and definitions as RRDTool does.
* <p>
* 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 very similar results and graphs.
* <p>
* RRD4J does not use native functions and libraries, has no Runtime.exec() calls and does not require
* RRDTool to be present. RRD4J is distributed as a software library (jar files) and comes with full
* java source code (Apache License 2.0).
* <p>
* You will not understand a single thing here if you are not already familiar with RRDTool. Basic
* concepts and terms (such as: datasource, archive, datasource type, consolidation functions, archive steps/rows,
* heartbeat, RRD step, RPN, graph DEFs and CDEFs) are not explained here because they have exactly the same
* meaning in RRD4J and RRDTool. If you are a novice RRDTool/RRD4J user,
* <a href="http://oss.oetiker.ch/rrdtool/tut/rrdtutorial.en.html">this annotated RRDTool tutorial</a> is a
* good place to start.
