<p><font face="Courier" size="2">Hi RRD Users,</font> </p><p><font face="Courier" size="2">I have an rrdfile router1.rrd that collects utilization data every 15 minutes. I want to print a single value which represents an AVERAGE rate over a 6 week period.</font></p><p><font face="Courier" size="2">I have read documentation and played around with this for several days and I haven't been able to figure it out.</font> </p><p><font face="Courier" size="2">The closest I came was this:</font> </p><p><font face="Courier" size="2">rrdtool graph - -s "midnight-6w" -e "midnight" \</font>
<br><font face="Courier" size="2">DEF:ds0=router1.rrd:ifInOctets:AVERAGE \</font>
<br><font face="Courier" size="2">VDEF:ds1=ds0,AVERAGE \</font>
<br><font face="Courier" size="2">PRINT:ds1:%20.2lf%s</font> </p><p><font face="Courier" size="2">At least this doesn't give me any errors, but it doesn't give me any output whatsoever.</font> </p><p><font face="Courier" size="2">Ideally I want to put this into a perl script like:</font> </p><p><font face="Courier" size="2">$average = RRDs::graph($rrdargs);</font> </p><p><font face="Courier" size="2">What am I doing wrong?</font> </p><br><p><font face="Courier" size="2">Tanya Ruttenberg</font>
