hwMemoryLargestFree
Module: A3COM-HUAWEI-MLSR-SYSTEM-MIB
OID (symbolic): A3COM-HUAWEI-MLSR-SYSTEM-MIB::hwMemoryLargestFree
OID (numeric): 1.3.6.1.4.1.43.45.1.2.2.5.3
Node type: OBJECT-TYPE
Type: Gauge
Access: read-only
Description: The largest free size of the contiguous area in memory. The unit is byte.
What is hwMemoryLargestFree?
This gauge shows the largest contiguous free block in bytes, indicating fragmentation state. If largest free block is small despite total free memory being large, memory fragmentation may prevent large allocations. Example: 200 MB free total but largest contiguous block only 50 MB suggests fragmentation stress.
Examples
