Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::cardMemoryUsage
OID (numeric): 1.3.6.1.4.1.277.1.7.2.1.32
Node type: OBJECT-TYPE
Type: Gauge
Access: read-only
Description: The memory utilization, in terms of free bytes, for this intelligent card.
What is cardMemoryUsage?
This reports the amount of free memory remaining on this card, in bytes. Watching this trend downward over days or weeks, rather than a single low reading, is what flags a memory leak in the card's firmware, since a card that's simply busy will show fluctuating free memory while a leaking one will show a steady one-directional decline toward zero. For example, cardMemoryUsage dropping from 40MB free to 2MB free over three weeks with no corresponding traffic increase points to a firmware memory leak requiring a scheduled reboot or upgrade.
Examples
Walk all instances (SNMPv2c):
