Description:
object-oriented interface to RRDTool
RRDTool::OO is an object-oriented Perl interface to Tobi Oetiker's round robin database tool, also known as rrdtool. It uses rrdtool's RRDs module to access rrdtool's shared library. It tries to marry rrdtool's database engine with the Perl programming language. . Using this module hides implementation details of the RRD engine, uses easy- to-memorize named parameters and sets meaningful defaults for parameters not needed in simple cases. For the experienced user, however, it still provides full access to rrdtool's API.
