Graphing RRD Files

[Jamie Lerner]

I have a large amount of historical data in RRD files. I would like to graph this data using JFreeChart instead of RRDTool. Is this possible? Does anyone have any example code?

Thanks,

Jamie.

Hi Jamie,

What is RRD?

RRD files are the files used by MRTG and RRDTool to store compressed time-series data. I think there is only a C/C++ interface, so I guess I would do JNI from my Java code to gather the data points and make the necessary JFreeChart calls to graph the data points. I was just hoping there was some sample code that I could use to start with.

Thanks,

Jamie.
