Garrulous answer: RRD is designed to do one thing well, normalise and store data at specified resolutions, in an economic way. It is not a general purpose database - if you want to store arbitrary data for arbitrary times and get the original data out then you should use a regular database. **ALL** data is normalised and consolidated according to the parameters used when creating the database. With some care* it is possible to make the normalisation a null operation, and using a consolidation process of one data point consolidated into one consolidated data point will make the consolidation a null operation as well - but both processes are still performed. Alex has an excellent set of tutorials at http://www.vandenbogaerdt.nl/rrdtool/ In particular, see "Rates, normalizing and consolidating" * To make normalisation a null operation, you must supply data values every step time, and they must be timestamped **exactly** on the step time boundary. These boundaries are always an integer multiple of step time since unix epoch (midnight, Jan 1, 1970 UTC) and this cannot be changed. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
