What is jnxFwddHeapUsage?

This read-only Gauge32 reports the FWDD heap memory utilization as a percentage, reading zero if unavailable or not applicable. An admin monitors this to catch a forwarding daemon that is consuming excessive heap memory, a potential sign of a memory leak or an oversized configuration (e.g. very large routing/filter tables). A value steadily climbing toward 100 percent over time would warn the admin of a potential forwarding-daemon memory exhaustion issue.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2636.3.34.1.3
snmpwalk -v2c -c public <target> JUNIPER-CHASSIS-FWDD-MIB::jnxFwddHeapUsage

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2636.3.34.1.3.1
snmpget -v2c -c public <target> JUNIPER-CHASSIS-FWDD-MIB::jnxFwddHeapUsage.1
