I changes it to: by removing the service part...

define nagios-template-enable() {
    notify{"Installing the config file now": }

    file { "/etc/nagios/$name.cfg":
      owner => 'root',
      group => 'root',
      mode => 644,
      content => template('nrpe/nrpe.cfg.erb'),
    }
  }
nagios-template-enable { 'nrpe.cfg': }
