If your application lends itself to having the data normalised to fixed time intervals, stored efficiently, and plotted on good quality graphs - then yet it may be of use to you. If not, then no it probably isn't the right tool. It would probably help you understand what RRD does, and decide if it's useful to you, if you took a look at Alex's tutorials : http://www.vandenbogaerdt.nl/rrdtool/ Specifically, "Rates, normalizing and consolidating" explains how it handles data that doesn't arrive on nice regular time interval boundaries. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
