Both! It depends which storage you want to measure. In the example
bellow 1 = Physical Memory 2 = Virtual Memory (This may change for
different systems).
The number at the beginning (1 or 2) is the index.
If you do the following command you get a table output. Column 1 is the
index. It is this number you use.
EXAMPLE:
-bash-3.00$ snmptable -cMyString -v1 <IP ADDRESS> hrStorageTable
SNMP table: HOST-RESOURCES-MIB::hrStorageTable
hrStorageIndex hrStorageType
hrStorageDescr hrStorageAllocationUnits hrStorageSize hrStorageUsed
hrStorageAllocationFailures
1 HOST-RESOURCES-TYPES::hrStorageRam Physical
memory 1024 Bytes 1022188 993792
?
3 HOST-RESOURCES-TYPES::hrStorageVirtualMemory Virtual
memory 1024 Bytes 3053796 993792
?
6 HOST-RESOURCES-TYPES::hrStorageOther Memory
buffers 1024 Bytes 176756 ?
?
7 HOST-RESOURCES-TYPES::hrStorageOther Cached
memory 1024 Bytes 575888 ?
?
8 HOST-RESOURCES-TYPES::hrStorageOther Shared
memory 1024 Bytes 0 ?
?
10 HOST-RESOURCES-TYPES::hrStorageVirtualMemory Swap
space 1024 Bytes 2031608 0
?
31 HOST-RESOURCES-TYPES::hrStorageFixedDisk
/ 4096 Bytes 16672164 1411974
?
32 HOST-RESOURCES-TYPES::hrStorageFixedDisk
/boot 1024 Bytes 101105 12120
?
and the command you used gives the total size of the Physical Memory.
-bash-3.00$ snmpwalk -cMyString -v1 <IP ADDRESS>
hrStorageTable.hrStorageEntry.hrStorageSize.1
HOST-RESOURCES-MIB::hrStorageSize.1 = INTEGER: 1022188
To get the used part of the Physical Memory, use:
-bash-3.00$ snmpwalk -cMyString -v1 <IP ADDRESS>
hrStorageTable.hrStorageEntry.hrStorageUsed.1
HOST-RESOURCES-MIB::hrStorageUsed.1 = INTEGER: 993544
Hope this helps.

Subject: how to monitor memory usage on freebsd systems
Hi All
I am trying monitor memory usage on a few Freebsd systems.
Running net-snmp-5.4.1.2 on Freebsd 6.2 and 5.4.
Question: How to monitor memory usage from the snmp info?
Is it
.iso.org.dod.internet.mgmt.mib-2.host.hrStorage.hrStorageTable.hrStorage
Entry.hrStorageSize.1 ?
Or
.iso.org.dod.internet.mgmt.mib-2.host.hrStorage.hrStorageTable.hrStorage
Entry.hrStorageSize.2 ?
Or something else?
Thank you.
Gui
