The SNMP Trap agent uses its own static UDR type called SnmpTrapUDR. There is also a special static UDR called FlatSnmpUDR used for unresolved triggered requests.

The SnmpTrapUDR contains data from a received SNMP trap, received by the SNMP Trap agent.

FieldDescription
trapSource (string)
The IP address or the remote host sending the trap.
receiveTime (long)

The UTC timestamp when the SNMP trap notification was received by the agent.

sysUpTime (string)

trapOid (string)

Value of snmpTrapOID, unique trap Object Identifier (OID). 0 as of RFC3418.

The name of the trap, resolved from loaded MIB data.
