>Description:
Using net-snmp-5.3.1 I try to query Real Memory which from my understanding should return the amount of built-in RAM:

[root_(_at_)_orakel ~]# snmpwalk -c public -v2c localhost HOST-RESOURCES-MIB::hrStorageDescr.2
HOST-RESOURCES-MIB::hrStorageDescr.2 = STRING: Real Memory
[root_(_at_)_orakel ~]# snmpwalk -c public -v2c localhost HOST-RESOURCES-MIB::hrStorageSize.2
HOST-RESOURCES-MIB::hrStorageSize.2 = INTEGER: 193455
[root_(_at_)_orakel ~]# snmpwalk -c public -v2c localhost HOST-RESOURCES-MIB::hrStorageSize.2
HOST-RESOURCES-MIB::hrStorageSize.2 = INTEGER: 193457
[root_(_at_)_orakel ~]# snmpwalk -c public -v2c localhost HOST-RESOURCES-MIB::hrStorageSize.2
HOST-RESOURCES-MIB::hrStorageSize.2 = INTEGER: 193516
[root_(_at_)_orakel ~]# snmpwalk -c public -v2c localhost HOST-RESOURCES-MIB::hrStorageSize.2
HOST-RESOURCES-MIB::hrStorageSize.2 = INTEGER: 193457
[root_(_at_)_orakel ~]#

[root_(_at_)_orakel ~]# snmpwalk -c public -v2c localhost HOST-RESOURCES-MIB::hrStorageAllocationUnits.2
HOST-RESOURCES-MIB::hrStorageAllocationUnits.2 = INTEGER: 4096 Bytes
[root_(_at_)_orakel ~]#

4096 Bytes*193457=792399872 Bytes=755 MBytes

I would expect Real Memory to be constant.

Anyway:

[root_(_at_)_orakel ~]# dmesg | grep -i memory
real memory  = 1073664000 (1023 MB)
avail memory = 1041477632 (993 MB)
[root_(_at_)_orakel ~]#

e.g. Windows (yeah, I know...) behaves as expected.

Install net-snmp, start snmpd, query values.
