Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: UCD-SNMP-MIB::memAvailReal

You'd better read the FAQ page of net-snmp,

http://www.net-snmp.org/wiki/index.php/FAQ:Applications_09

You should use

snmpget -v 1 -c public localhost .1.3.6.1.4.1.2021.4.6.0.
