check_snmp is included as part of the nagios-plugins package. It's a totally separate thing from Nagios Core.

If you're following the official documentation for installing Nagios Core, there should be a "Installing The Nagios Plugins" step which should include the check_snmp plugin.

Can you share an updated copy of: /usr/local/nagios/etc/nagios.cfg /usr/local/nagios/etc/hostTemplates.cfg This doesn't have anything to do with NSClient++ as of right now .
