# # calculate the average, avoiding any division by zero traps # my $avg_cpu_load = $total_cpu_load ? $total_cpu_load / $active_pid_num + : 0 ;

I'd think if you want to avoid division by zero, you'd need to check the denominator for zero-ness rather than the numerator. That is:

my $avg_cpu_load = $active_pid_num ? $total_cpu_load / $active_pid_num + : 0;

Or am I misunderstanding something here?
