<div>You might also want to increase the length of the RRA proportionally, as well, and maybe decrease the DS heartbeat (as you have a shorter step size now). Also, with a 1-dp RRA, you dont need to have the MIN and MAX, as they will be the same as the AVG for a group of a single point.</div>

<div><font size="2" face="Arial">rrdtool create arcsize.rrd --start N --step 15 DS:arcsize:GAUGE:30:0:5000 RRA:AVERAGE:0.5:1:43920</font></div>
<div><font size="2" face="Arial"></font> </div>
