memAvailRealTXT

Module: UCD-SNMP-MIB

OID (symbolic): UCD-SNMP-MIB::memAvailRealTXT

OID (numeric): 1.3.6.1.4.1.2021.4.10

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The amount of real/physical memory currently being used by text pages on this host.

This object will not be implemented on hosts where the underlying operating system does not distinguish text pages from other uses of physical memory.

Note that (despite the name), this value reports the amount used, rather than the amount free or available for use. For clarity, this object is being deprecated in favour of 'memUsedRealTXT(17).

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2021.4.10
snmpwalk -v2c -c public <target> UCD-SNMP-MIB::memAvailRealTXT

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2021.4.10.1
snmpget -v2c -c public <target> UCD-SNMP-MIB::memAvailRealTXT.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> memAvailRealTXT.1

Start monitoring Unix/Linux servers running the Net-SNMP (net-snmp/snmpd) agent (CPU/memory/disk/process-table status) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the UCD-SNMP-MIB::memAvailRealTXT OID value, configure state conditions and alerts, and monitor any Unix/Linux servers running the Net-SNMP (net-snmp/snmpd) agent (CPU/memory/disk/process-table status) from a single console.
