memActiveVirtual
Module: CHECKPOINT-MIB
OID (symbolic): CHECKPOINT-MIB::memActiveVirtual
OID (numeric): 1.3.6.1.4.1.2620.1.6.7.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Active virtual memory (32 bit) NOTE: This 32 bit object has been superseded by a 64 bit object - memActiveVirtual64, which is supported by Check Point SVN FP3 and above.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 memActiveVirtual?
This INTEGER reports currently active (in-use) virtual memory via the same legacy 32-bit counter, explicitly deprecated in favor of memActiveVirtual64 per its description. Active virtual memory reflects what processes are actually using right now as opposed to merely allocated/reserved, so tracking it (via the 64-bit version on modern boxes) helps spot memory pressure building up. A value that appears to reset to a small number unexpectedly on a machine with lots of RAM is the overflow behavior the description explicitly warns about, not a real drop in usage.
Examples
