It hasn't become clear to me why you need to execute the
check_nrpe plugin itself via sudo?
This plugin is meant to be executed by the uid the nagios server
is running under.
What matters are any possible constraints for check_custom_plugin
(or whatever you pass to -c)
that needs to be executed remotely on the nrpe node.
Thus constraints there, on the nrpe node, must be met and
privileges possibly elevated by some sudo rule if necessary.
