I had the same issue, snmp was missing. Resolved installing basic snmp and recompiling nagios plugins. nagios-plugins-1.4.15# apt-get install snmp nagios-plugins-1.4.15# ./configure --with-nagios-user=nagios --with-nagios-group=nagios nagios-plugins-1.4.15# make clean nagios-plugins-1.4.15# make nagios-plugins-1.4.15# make install And green lights appear !
