Hello Alex,

I think I know  what the problem is; your plugin is supposed to give 
only one line of output (unles you use Nagios 3).
However, upon your execution, the first line of output is :

"Use of uninitialized value in scalar chomp at ./check_iftraffic.pl line 
185, <FILE> line 1."

So I think there is a problem with the plugin or the perl interpreter. 
Do you use the embedded perl interpreter ?
I use the same plugin from NagiosExchange but don't experience any 
problems with it. I always disable the embedded perl interpreter in Nagios.

Good luck,

Frederik
