RRDCacheD is a data caching daemon for rrdtool. It receives updates to
existing RRD files, accumulates them and, if enough have been received or a
defined time has passed, writes the updates to the RRD file.
The daemon was written with big setups in mind.
A data analysis tool generating graphical representations.
