Author:

peter A java interface to Tobi Oetikers rrdtool. This provides rrd operations to java programs. It puts a layer on top of the actual job to invoke rrdtool functionality. By default, it uses the rrdtool pipe mode of operation with a single instance of rrdtool. It can use other backends as well, eg. a RRDCommandPool. The entire machinery is quite flexible.
