mbufWaits
Module: BSDUNIX-MIB
OID (symbolic): BSDUNIX-MIB::mbufWaits
OID (numeric): 1.3.6.1.4.1.4.2.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of requests for mbufs which resulted in a wait.
What is mbufWaits?
Tracks how many times a request for a memory buffer (mbuf) could not be fulfilled immediately and had to wait, indicating memory pressure in the kernel networking subsystem. High values suggest the system is under heavy network load or is running low on mbuf resources.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4.2.5 snmpwalk -v2c -c public <target> BSDUNIX-MIB::mbufWaits
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4.2.5.1 snmpget -v2c -c public <target> BSDUNIX-MIB::mbufWaits.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> mbufWaits.1
Start monitoring BSD Unix hosts (legacy ISODE SNMP agent) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the BSDUNIX-MIB::mbufWaits OID value, configure state conditions and alerts, and monitor any BSD Unix hosts (legacy ISODE SNMP agent) from a single console.
