# 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?
