JRobin is a 100% pure java implementation of RRDTool\'s functionality. It follows the same logic and uses the same data sources, archive types and definitions as RRDTool does. JRobin supports all standard operations on Round Robin Database files: CRE
Tutorial Details:
If you provide the same data to RRDTool and JRobin, you will get exactly the same results and graphs. JRobin is made from the scratch and it uses very limited portions of RRDTool\'s original source code. JRobin does not use native functions and libraries, has no Runtime.exec() calls and does not require RRDTool to be present. JRobin is distributed as a software library and comes with full
RDTool for Internet traffic monitoring in a complex, commercial project. Front-end application (data sampling and validation) was written in Java, but RRDTool did all the hard work. No doubt that RRDTool is a wonderful and very useful tool especially for those inclined to pure C/C++ or scripting languages like Perl or PHP, but I am a Java addict since I discovered this superior programming language. Java does not prohibit usage of external tools, scripts and native libraries but such practice breaks the basic Java motto (\"code once, run everywhere\") and should be avoided whenever possible. Having finished some swift researches I was astonished that nobody tried to implement the same concept in pure Java. Even OpenNMS, excellent Java application for network monitoring used its own JNI library as a wrapper around RRDTool.
