java - 在 SNMP 陷阱报头中发送 OID

Question

我有一个使用 SNMP4J 发送 SNMP 陷阱的 Java 应用程序。问题是 OID 在陷阱正文中发送。我设置的所有数据都已成功发送，但在陷阱正文中。我希望 Oid 在陷阱报头中发送。

如何在 Trap header 中发送 Oid？

    UdpAddress managerUdpAddress = new UdpAddress("address");

    CommunityTarget ctarget = new CommunityTarget();
    ctarget.setAddress(managerUdpAddress);
    ctarget.setRetries(retryCount);
    ctarget.setCommunity(new OctetString(community));
    ctarget.setTimeout(timeout);
    ctarget.setVersion(SnmpConstants.version2c);

    PDU trap = new PDU();

    OID oid = new OID(myOid);
    trap.add(new VariableBinding(SnmpConstants.snmpTrapOID, oid));
    trap.add(new VariableBinding(SnmpConstants.sysUpTime, new TimeTicks(5000)));                
    trap.add(new VariableBinding(SnmpConstants.sysDescr, new OctetString(
        "System Description")));
    trap.add(new VariableBinding(oid, new OctetString(message)));

    DefaultUdpTransportMapping  transport = new DefaultUdpTransportMapping();

    Snmp snmp = new Snmp(transport);

    snmp.notify(trap, ctarget);

当 UPS 发送 SNMP 陷阱时，OID 出现在 SNMP 陷阱报头中。以下是示例:

来自 UPS 的陷阱:

Mon Mar 18 04:13:18 2019 .1.3.6.1.4.1.935.0.49 Normal "SNMP EVENT" x.x.x.x - UPS_212_bypass_ac_normal SNMP TRAP: Bypass AC Normal

来自JAVA的陷阱:

Mon Mar 18 05:25:36 2019 .0.00 Critical "SNMP EVENT" x.x.x.x - my application snmp errors: System Description General error. Size=2"

Answer 1

我通过添加以下代码来做到这一点:

trap.setType(PDU.TRAP);
trap.add(new VariableBinding(oid));

现在从 Java 发送的 SNMP 陷阱如下所示:

Thu Mar 21 15:16:51 2019 .1.3.6.1.6.3.1.1.7.1.6 Critical "SNMP EVENT" x.x.x.x - my application snmp errors: System Description General error. Size=2"
