If the last update was at time 10:55, and now is 10:58, maybe rrdtool returns the interval starting at 10:55 and ending at 11:00. This interval is not yet filled with data and thus is unknown. When you ask for "--end now-5min", you will effectively be asking for the period "10:50 to 10:55" which is available and not unknown. When you ask for an end time of "10:55", I think rrdtool should also return the interval 10:50 to 10:55. In other words, make sure you ask for a multiple of 5 minutes (more precise, a multiple of step) in stead of "now-5min".
