<div dir="ltr">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:<div>
<br></div><div><div>$ rrdtool fetch disk,root.rrd AVERAGE -r 300 -s -2d -e now|tail -5</div><div>1387319100: 8.0000000000e+01 7.8994000000e+05</div><div>1387319400: 8.0000000000e+01 7.8994000000e+05</div><div>1387319700: nan nan</div>
<div>1387320000: nan nan</div><div>1387320300: nan nan</div><div>$ rrdtool fetch disk,root.rrd AVERAGE -r 300 -s -3d -e now|tail -5</div><div>1387314000: 8.0000000000e+01 7.8994000000e+05</div><div>1387315800: 8.0000000000e+01 7.8994000000e+05</div>
<div>1387317600: 8.0000000000e+01 7.8994000000e+05</div><div>1387319400: 8.0000000000e+01 7.8994000000e+05</div><div>1387321200: nan nan</div><div><br></div><div>The interval for -2d is 300s; for -3d is 1800s. In fact, the "-r" is probably being over-ridden by the sample interval of the consolidated data being requested.</div>
