I'm not sure what you're suggesting here. Normally, I create a rrd DB without specifying a start time (doesn't it default to now?) then updates after this would be inserted at the current time (N). Why should that cause a unknown value to be stored as 0? The problem I had was this: I created an rrd to store weather data with several data points. One of the DSs, windchill, is unknown this time of year, but it was being stored as 0. I confirmed that my update script was putting the proper U for that point, but it still stored 0. I let it run for a few days just to be sure (since it only updated once per hour, it takes a while to see changes) but nothing changed. I created the same rrd file using the exact same command, only changing which version of rrdtool was called (to 1.0 from 1.2) and everything worked fine. -- Salvatore D.
