RRD-Tweak This is a module for manipulating the structure of RRDtool files. It can read a file, alter its DS and RRA structure, and save a new file. It also allows creating new empty RRD files in memory or on the disk. The file read/write operations are implemented in native C. The module links with librrd, so the librrd library and its header files are required for building the RRD::Tweak module. The module is tested with RRDtool versions 1.3 and 1.4. As the RRD file format is architecture dependent, RRD::Tweak can only read files which are created by RRDtool in the same processor architecture.
