[rrd-users] One little Newbie Question

[clinder]

Hi everyone,

my boss wants me to raise up a network monitoring system so i just started
with rrdtool a few days ago.
i read a lot of tutorials and documentation but there are a lot of questions
left. here is one of them.

1. i use the perl module RRDs to access and  fetch the database. i created
my test DB with:

  RRDs::create($DB, "--step=60",
    "DS:cpu-load:GAUGE:66:U:U", 
    "RRA:MAX:0.5:1:60",
    "RRA:MAX:0.5:60:24",
    "RRA:MAX:0.5:1440:7",
  ) or die $RRDs::error;

so everybody can see that rdd's stepsize is 60 sec. right?

Now i tried to fetch some data with:

    my ($start, $step, $names, $data) =
     RRDs::fetch($DB, "MAX");

printing $step says: stepsize would be 3600

Why?

thanks a lot in advance
Chris
