What is nodedown?
This notification is triggered when a monitored node appears to be offline or unresponsive. The event carries a hostname, severity level, and descriptive text about why the node is considered down. Network operators use this trap to quickly identify and respond to nodes that have failed or become unreachable.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' OPCD-SUPPORT-MIB-V2::nodedown snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.30374.3.1.0.40
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
