The problem is that without **significantly** changing the data model, it is not possible to store arbitrary data at arbitrary times without normalisation. The data model simply does not deal with timestamped data, all data is normalised into regularly sized 'bins'. IFF you feed in data on each step boundary (not a second early, not a second late, and don't miss any), then normalisation is a null operator and what you feed in will be what's stored (after conversion to a floating point). But you obviously can't do consolidation without breaking that. See http://www.vandenbogaerdt.nl/rrdtool/ In particular, see the tutorial on "Rates, normalizing and consolidating" for an explanation of what rrd tool does. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
