cucsComputeServerUnitAvailableMemory
Module: CISCO-UNIFIED-COMPUTING-COMPUTE-MIB
OID (symbolic): CISCO-UNIFIED-COMPUTING-COMPUTE-MIB::cucsComputeServerUnitAvailableMemory
OID (numeric): 1.3.6.1.4.1.9.9.719.1.9.74.1.9
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: Cisco UCS compute:ServerUnit:availableMemory managed object property
What is cucsComputeServerUnitAvailableMemory?
This Gauge32 'availableMemory' reports the amount of RAM (in MB) on this server that is currently free rather than already committed. Comparing this to totalMemory on the same object is how a capacity-planning admin checks headroom on a specific blade before assigning it a memory-hungry workload. A blade with 256 GB installed and a heavy VM footprint might report availableMemory as `32768` (32 GB) still free.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.9.74.1.9 snmpwalk -v2c -c public <target> CISCO-UNIFIED-COMPUTING-COMPUTE-MIB::cucsComputeServerUnitAvailableMemory
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.9.74.1.9.1 snmpget -v2c -c public <target> CISCO-UNIFIED-COMPUTING-COMPUTE-MIB::cucsComputeServerUnitAvailableMemory.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cucsComputeServerUnitAvailableMemory.1
