G'day Monks,

I have been writing a script to monitor the capacities of various disks and databases in my work environment. During this process i have found myself working with the following Hash of Hashes

$stuff    =    { 
        production => {
                 windows  => {
                        Hostname => {    
                                targetname1 = {    
                                        total_capacity = value,
                                        free_capacity  = value
                                          },
                                targetname2 = {    
                                        total_capacity = value,
                                        free_capacity  = value
                                          }
                                }            
                        },
                 unix     => {
                        Hostname => {    
                                targetname1 = {    
                                        total_capacity = value,
                                        free_capacity  = value
                                          },
                                targetname2 = {    
                                        total_capacity = value,
                                        free_capacity  = value
                                          }
                                }            
                        },
                 database => {
                        Hostname => {    
                                targetname1 = {    
                                        total_capacity = value,
                                        free_capacity  = value
                                          },
                                targetname2 = {    
                                        total_capacity = value,
                                        free_capacity  = value
                                          }
                                }            
                        }
                      },
        development => { 
                windows  => { etc. etc.},
                unix     => { etc. etc.},
                database => { etc. etc.}
                   }
        }

While this perfectly describes the information i'm working with it becomes a bit unwieldy when working with it. I have had to resort to a bunch of nested 'while' loops

while(my($env,$platform_href) = each %{$stuff}) {
    while(my($platform,$host_href) = each %{$platform_href}) {
        while(my($host,$target_href) = each %{$host_href}) {
            while(my($target,$capacity_href) = each %{$target_href}) {
                
                # Do stuff with
                # $env
                # $platform
                # $host
                # $target
                # $capacity_href->{'total_capacity'};
                # $capacity_href->{'free_capacity'};

            }
        }
    }
}

Nasty eh?

Is there a better/prettier way of traversing the data structure or even a better way of representing the data with a different structure?

Many Thanks,
