RRD::Simple provides a simple interface to RRDTool's RRDs module.
This module does not currently offer the graph, fetch or info
methods that are available in the RRDs module.

It does howeve create RRD files with a sensible set of default RRA
(Round Robin Archive) definitions, and can dynamically add new
data source names to an existing RRD file.

This module is ideal for quick and simple storage of data within an
RRD file if you do not need to, nor want to bother defining custom
RRA definitions.
