mbufDrains
Module: BSDUNIX-MIB
OID (symbolic): BSDUNIX-MIB::mbufDrains
OID (numeric): 1.3.6.1.4.1.4.2.6
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of times protocols were drained for space.
What is mbufDrains?
Counts the number of times the kernel had to drain protocol buffers to free up space for new memory buffers. This is a sign of memory contention in the network stack, where existing protocol data had to be discarded to reclaim resources.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4.2.6 snmpwalk -v2c -c public <target> BSDUNIX-MIB::mbufDrains
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4.2.6.1 snmpget -v2c -c public <target> BSDUNIX-MIB::mbufDrains.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::mbufDrains OID value, configure state conditions and alerts, and monitor any BSD Unix hosts (legacy ISODE SNMP agent) from a single console.
