[Orca-users] Re: Too many Disk graphs

[Gary Kakazu]

I investigated this a while ago and found a fix the reduced the number
of duplicate graphs, but did not necessarily eliminate all duplicates.
This fix is primarily helpful when the order of the columns gets
rearranged in you orcallator file. The fix won't help if you mount and
umount 1 or more file systems over a period of time.

Here's a context diff of what I did (basically just sort 2 lists):

      my $image;
!     my $all_names_with_subgroup = join(',', @name_with_subgroup);
      if (defined ($image =
$image_files_ref->{hash}{$all_names_with_subgroup})){
        $image->add_rrds(@my_rrds);
      } else {

      if (defined ($image =
$image_files_ref->{hash}{$all_names_with_subgroup})){
        $image->add_rrds(@my_rrds);
      } else {

                                      join(',', @my_short_rrds),
