You are filling up the hash just fine, but the problem is that you're going about retrieving the data from it all wrong. The hash %db_processes is a different variable than @db_processes the array. In your foreach statement, you are trying to get data out of the array variable (psst, using strict would have pointed this out) which is why you aren't getting anything at all to print.

To get back data from a hash in a similar way, either use keys, each, or values. If it were me, I'd use each in this case: 

while (my($key, $hashy) = each %db_process) {
   # same inner loop

   # also, since $hashy is anticipated to be a HASH reference, 
   # you can't do  $hashy->[0], etc.
   
   # you must use $hashy->{key} (with the curly, not square brackets)
}
