What is memUsedRealTXT?

This OID reports the amount of real/physical memory, in kilobytes, currently occupied by executable text pages on this host, when the OS distinguishes text pages from other memory. An admin can use it to see how much RAM is tied up by program code rather than data.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2021.4.17
snmpwalk -v2c -c public <target> UCD-SNMP-MIB::memUsedRealTXT

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2021.4.17.1
snmpget -v2c -c public <target> UCD-SNMP-MIB::memUsedRealTXT.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::memUsedRealTXT 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.
