You cannot order hash keys, by definition, their order is arbitrary.

What I understand by first pass means that for one key $host from %nodes, $rrd takes on the values from %rrd in thje way you expect, but it does not for the other keys in %nodes. I doubt that is what you mean ... or if it is, you are not showing the relevant coded, since %rrd is not modified in the code you present.

How about putting a print statement in the inner loop, to see what is happening?

for my $host(keys %nodes) {
  for my $rrd(keys %rrd) {
    printf "host: %s\trrd: %s\n", $host, $rrd;
#    my $avg = &get_latest_avg($host,$rrd,'free');
#    print $avg. "\n";
  }
}
