Are you testing this as root? If so, don't. Test as the nagios user.

$result isn't a variable that gets populated. That's just something  
displayed in the verbose output for human consumption. It's the exit  
code that matters. Use 'echo $?' immediately after running the plugin.

Here you're using sudo, which is a non-trivial difference compared to  
your apparent test above. A few comments --
	- specify the full path to sudo
	- test the above command as the nagios user; make sure it works  
without being prompted for a password.
	- make sure 'requiretty' is disabled in sudoers.
