You might try rrdtool fetch subdata.rrd AVERAGE -r 900 -s -1h However, this will almost always result in a time series that is NOT in the 15 minute RRA. Confidence bands for the observed time series are generated by scaling the sequence of predicted deviation values (we usually think of the sequence as a continuous line rather than a set of discrete points). RRDtool provides the building blocks for near real-time aberrant behavior detection. teatime (16:00). 12/31/99 11:59pm --- 1 minute to the year 2000 for imperialists.
