<p class="MsoNormal">The rrd file contains 5-minute data only going back so far (typically 576 samples, or 48 hours). If you ask for data from before that point in time, rrdtool will switch to the next interval of consolidated data to give you the earlier
data points you requested. Try setting your start time to "-1d", and you should see 5-minute samples. For example, the difference between 2 days and 3 days:<o:p></o:p></p>
