Here are my first try:

#!/usr/bin/perl
use RRDs;
$i=10;
$creqin=1000;
$time= `perl -e 'print time'`;
print $time;
`rrdtool create sip.rrd --start $time --step 1 DS:creqin:GAUGE:1:0:1000 RRA:MAX:0.5:1:24 `;
$time+=1;

while( $i > 0 ){
    $creqin=`/usr/local/bin/snmpget -v 1 -c public -Oqv localhost 1.3.6.1.2.1.9990.1.5.1.1.1.1 `;
    RRDs::update ("sip.rrd","$time:$creqin");
    $i-=1;
    $time+=1;
    }

`rrdtool graph sip.gif --start $time_alt --end $time DEF:sip=sip.rrd:creqin:MAX LINE2:sip#FF0000`;
