jRRD is a package that allows Round Robin Database (RRD) files generated by the Multi Router Traffic Grapher (MRTG) or other similar softwares to be read from Java programs. jRRD is aimed at Java developers who would like to access RRD files without having to resort to using the JNI.

The project has been idle for some years but a new version with RRD files version 3 and x86_64 files support is now available.
