What is mbufFrees?

Reports the current number of memory buffers (mbufs) that have been allocated but are not actively in use, representing the free pool available for network operations. A very low count may indicate impending mbuf exhaustion.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4.2.7
snmpwalk -v2c -c public <target> BSDUNIX-MIB::mbufFrees

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4.2.7.1
snmpget -v2c -c public <target> BSDUNIX-MIB::mbufFrees.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::mbufFrees OID value, configure state conditions and alerts, and monitor any BSD Unix hosts (legacy ISODE SNMP agent) from a single console.
