pfCntMemory
Module: OPENBSD-PF-MIB
OID (symbolic): OPENBSD-PF-MIB::pfCntMemory
OID (numeric): 1.3.6.1.4.1.30155.1.2.6
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The number of packets that were dropped due to memory limitations.
What is pfCntMemory?
Counts packets dropped because pf ran out of memory in one of its internal pools (e.g., for state entries) rather than being blocked by policy. A rising count is a signal to review pf's memory limits (pfLimitStates, pfLimitFragments, etc.) since the firewall may be resource-constrained.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.30155.1.2.6 snmpwalk -v2c -c public <target> OPENBSD-PF-MIB::pfCntMemory
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.30155.1.2.6.1 snmpget -v2c -c public <target> OPENBSD-PF-MIB::pfCntMemory.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> pfCntMemory.1
