mbufDrops
Module: BSDUNIX-MIB
OID (symbolic): BSDUNIX-MIB::mbufDrops
OID (numeric): 1.3.6.1.4.1.4.2.4
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of requests for mbufs which failed due to lack of space.
What is mbufDrops?
Counts the number of times a request to allocate an mbuf (kernel network memory buffer) failed because no memory was available. This read-only counter indicates kernel buffer exhaustion events that can lead to packet loss on BSD Unix systems.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4.2.4 snmpwalk -v2c -c public <target> BSDUNIX-MIB::mbufDrops
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4.2.4.1 snmpget -v2c -c public <target> BSDUNIX-MIB::mbufDrops.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::mbufDrops OID value, configure state conditions and alerts, and monitor any BSD Unix hosts (legacy ISODE SNMP agent) from a single console.
