memFreeReal
Module: CHECKPOINT-MIB
OID (symbolic): CHECKPOINT-MIB::memFreeReal
OID (numeric): 1.3.6.1.4.1.2620.1.6.7.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Free real memory (32 bit) NOTE: This 32 bit object has been superseded by a 64 bit object - memFreeReal64, which is supported by Check Point SVN FP3 and above. The 32 bit object is still supported, but it is recommended to work with the new 64 bit object (avoid receiving erroneous values from 64 bit machines).
What is memFreeReal?
This INTEGER reports free physical memory via the legacy 32-bit counter, superseded by memFreeReal64 per its description. Free real memory approaching zero is a direct precursor to swapping and degraded performance, making this (or its 64-bit successor) one of the most operationally urgent values in the whole memory group to alert on. A steadily declining trend toward zero here, correlated with rising memSwapsSec, would be the classic signature of a gateway about to run out of usable RAM.
