[rrd-developers] Need Help

[Gillma Gillma]

Hi there,

   I am trying to create an RRD table for 15 min interval.
   push (@args,  "test$rrdtype.rrd", '-b', $START, '-s', '900');
   push (@args, "DS:ifcoll:GAUGE:900:U:U");
   push (@args, "DS:ifInTraffic:GAUGE:900:U:U");
   push (@args, "DS:ifOutTraffic:GAUGE:900:U:U");
   push (@args, "RRA:AVERAGE:0.5:1:9600");
   push (@args, "RRA:AVERAGE:0.5:4:9600");
   push (@args, "RRA:AVERAGE:0.5:24:9600");
   RRDs::create(@args);

   Once i have create the table and i have written a perl script to store 
some raw values into the tables and i am storing the raw values in a log 
file too.

  But when i compare both the values i find a big difference.
RRD value in rrd table

Log file values
2	   521700		1366879

1	   241534		600880
0	   280406		821603
0	   287702		613502
0	   166280		525263
0	   149282		520013
0	   153974		554736

and my cron job runs on 3,18,33,48 * * * * interval.

I can't understand whether the values are wrong or its that's the way rrd 
store the values.
