#!/usr/bin/perl
use strict;
my $keys;
my @values;
@values=qx(/usr/local/rrdtool-1.0.39/bin/rrdtool fetch test.rrd AVERAGE
-s -600 -e -300);
## Now you've got the values inside the array @values
chomp @values;
## Now no more \n
foreach $keys (@values) {
print "$keys\n";
}
##Shows you the content of the array
If you don't know that much about perl, you can access the array with
@values[0], @values[1], @values[2]
Best regards,
Stephan
