As the perl motto has it, "there's more than one way to do it."  An
alternative solution would be to rearrange the parameters so that
$OUTPUT$ is the last parameter.  Then after shifting out the hostname,
etc., what is left is $OUTPUT$. 

 $hostname = shift;
 $status = shift;
 $servicedesc = shift;
 $datetime = shift;
 $output = join(' ', @ARGV); 

Back in the days before perl had references, this sort of trick was the
standard way of coding subroutines which took multiple parameters, one of
which was an array - pass the scalars first and the array last. 

This approach is not better than yours, it's just one that I'd hope a
competent perl coder would have used instinctively.  Mr Aait didn't...
