Due to security issues nrpe-server in Debian Jessie is now compiled without "--enable-command-args". If you want to use it you have to recompile it.
nagios-nrpe (2.15-1) unstable; urgency=high This update disables the command-args support in nrpe. The feature has several security problems and is often used wrong. If you have to use this feature recompile the package with --enable-command-args in debian/rules. -- Alexander Wirt

Maybe that's a good point of time to use check_mk..
