What is hwMemFree?
This OID returns an integer value in bytes representing the amount of unallocated memory currently available on the device. Operators track this metric to ensure sufficient memory headroom for dynamic processes and to trigger alerts before memory starvation affects routing table or ARP cache performance. An example value is 536870912, representing 512 MB of free memory.
