I have a script thats gathers cpu(using extract command) info for a numerous servers and prints the output to a file. It makes a file for a cluster thens removes it and then moves on to the next cluster. for example server1 and server2 would be cluster1 and server3 and server4 would be cluster2. I then open the output file and get a average for every hour for the day. The problem I have is when I print the average it prints it twice for each cluster because their is two servers in the cluster when i only need it to print once. Here is my code and example of my output file would look like. 

sub get_avr {
        my ($cluster) = @_;
        
        open(IN, "$outputfile");
        while (<IN>) {
          foreach my $hour (0 .. 23){
            $_ =~ tr/ //s;
           ($date,$time,$cpu{$hour},$io,$rate,$mem) = split(/ /, $_);
                       if ($time =~ /$hour:00/){
                          $tmem{$hour} = ($tmem{$hour} + $cpu{$hour});
                          $cnt{$time}++;
                          $avr{$hour} = ($tmem{$hour} / $cnt{$time});
                                print "$cluster $time $avr{$hour}\n";
                       }
                 }
       }
}

my print would look something like this:
cluster1 00:00 43.45
cluster1 00:00 43.45 (But every hour would be printed)
this is the right infomation but i need it to print once not twice.
Here is what my outputfile would look like for a cluster before i open it:
05/08/06 00:00 51.84 1915510 1061 66.13
05/08/06 01:00 25.67 1255510 648 66.07
05/08/06 00:00 35.56 2077540 739 66.26
05/08/06 01:00 33.91 2262510 718 66.37
and of course their would be more the just the hours of 00:00 and 01:00. thanks for any help sorry for any thing that is miss typed.
