hwMemoryDevLargestFree
Module: HUAWEI-DEVICE-MIB
OID (symbolic): HUAWEI-DEVICE-MIB::hwMemoryDevLargestFree
OID (numeric): 1.3.6.1.4.1.2011.6.3.5.1.1.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The maximum size of the memory that can be currently used, in the unit of byte.
What is hwMemoryDevLargestFree?
The size, in bytes, of the single largest contiguous block of free memory currently available. If this shrinks even while total free memory looks fine, it's a sign of memory fragmentation that can still cause large-allocation failures.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2011.6.3.5.1.1.5 snmpwalk -v2c -c public <target> HUAWEI-DEVICE-MIB::hwMemoryDevLargestFree
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2011.6.3.5.1.1.5.1 snmpget -v2c -c public <target> HUAWEI-DEVICE-MIB::hwMemoryDevLargestFree.1
