Enable NRPE debug mode and look in /var/log/messages for errors.
Ensure that you do not have the sudoers option 'requiretty' enabled.

This is expected to break. You didn't add /usr/local/nagios/libexec/ 
check_nrpe to the sudoers file (that you've shown), nor should you  
need/want to. Don't use sudo here.

Take a deep breath... We're happy to help get non-standard plugins  
working if we can. With what you've posted so far, NRPE seems to be  
properly configured and you might just have a problem with sudo or  
your custom plugin. sudo can be finicky.

I can think of several reasons off-hand why this statement wouldn't be  
true, not least of which is your test above ;) As a general rule  
though, it's ok. =)

NRPE, probably; nagisk-plugin, maybe not so much since we don't know  
where you got it, how it works or what it's requirements are.
