利用SNMP4J实现Snmp Trap完整例子

下面是两个用于发送和接收Trap报文信息的类:java

import java.io.IOException; import java.net.UnknownHostException; import java.util.Vector; import org.snmp4j.CommandResponder; import org.snmp4j.CommandResponderEvent; import org.snmp4j.MessageDispatcherImpl; import org.snmp4j.Snmp; import org.snmp4j.TransportMapping; import org.snmp4j.mp.MPv1; import org.snmp4j.mp.MPv2c; import org.snmp4j.mp.MPv3; import org.snmp4j.security.SecurityModels; import org.snmp4j.security.SecurityProtocols; import org.snmp4j.security.USM; import org.snmp4j.smi.Address; import org.snmp4j.smi.GenericAddress; import org.snmp4j.smi.OctetString; import org.snmp4j.smi.TcpAddress; import org.snmp4j.smi.UdpAddress; import org.snmp4j.smi.VariableBinding; import org.snmp4j.transport.DefaultTcpTransportMapping; import org.snmp4j.transport.DefaultUdpTransportMapping; import org.snmp4j.util.MultiThreadedMessageDispatcher; import org.snmp4j.util.ThreadPool; /** * 本类用于监听代理进程的Trap信息 * * @author martin * */ public class MultiThreadedTrapReceiver implements CommandResponder { private MultiThreadedMessageDispatcher dispatcher; private Snmp snmp = null; private Address listenAddress; private ThreadPool threadPool; public MultiThreadedTrapReceiver() { // BasicConfigurator.configure(); } private void init() throws UnknownHostException, IOException { threadPool = ThreadPool.create("Trap", 2); dispatcher = new MultiThreadedMessageDispatcher(threadPool, new MessageDispatcherImpl()); listenAddress = GenericAddress.parse(System.getProperty( "snmp4j.listenAddress", "udp:192.168.1.23/162")); // 本地IP与监听端口 TransportMapping transport; // 对TCP与UDP协议进行处理 if (listenAddress instanceof UdpAddress) { transport = new DefaultUdpTransportMapping( (UdpAddress) listenAddress); } else { transport = new DefaultTcpTransportMapping( (TcpAddress) listenAddress); } snmp = new Snmp(dispatcher, transport); snmp.getMessageDispatcher().addMessageProcessingModel(new MPv1()); snmp.getMessageDispatcher().addMessageProcessingModel(new MPv2c()); snmp.getMessageDispatcher().addMessageProcessingModel(new MPv3()); USM usm = new USM(SecurityProtocols.getInstance(), new OctetString(MPv3 .createLocalEngineID()), 0); SecurityModels.getInstance().addSecurityModel(usm); snmp.listen(); } public void run() { try { init(); snmp.addCommandResponder(this); System.out.println("开始监听Trap信息!"); } catch (Exception ex) { ex.printStackTrace(); } } /** * 实现CommandResponder的processPdu方法, 用于处理传入的请求、PDU等信息 * 当接收到trap时，会自动进入这个方法 * * @param respEvnt */ public void processPdu(CommandResponderEvent respEvnt) { // 解析Response if (respEvnt != null && respEvnt.getPDU() != null) { Vector<VariableBinding> recVBs = respEvnt.getPDU().getVariableBindings(); for (int i = 0; i < recVBs.size(); i++) { VariableBinding recVB = recVBs.elementAt(i); System.out.println(recVB.getOid() + " : " + recVB.getVariable()); } } } public static void main(String[] args) { MultiThreadedTrapReceiver multithreadedtrapreceiver = new MultiThreadedTrapReceiver(); multithreadedtrapreceiver.run(); } } app

import java.io.IOException; import java.util.Vector; import org.snmp4j.CommunityTarget; import org.snmp4j.PDU; import org.snmp4j.Snmp; import org.snmp4j.TransportMapping; import org.snmp4j.event.ResponseEvent; import org.snmp4j.mp.SnmpConstants; import org.snmp4j.smi.Address; import org.snmp4j.smi.GenericAddress; import org.snmp4j.smi.OID; import org.snmp4j.smi.OctetString; import org.snmp4j.smi.VariableBinding; import org.snmp4j.transport.DefaultUdpTransportMapping; /** * 本类用于向管理进程发送Trap信息 * * @author martin * */ public class SnmpUtilSendTrap { private Snmp snmp = null; private Address targetAddress = null; public void initComm() throws IOException { // 设置管理进程的IP和端口 targetAddress = GenericAddress.parse("udp:192.168.1.23/162"); TransportMapping transport = new DefaultUdpTransportMapping(); snmp = new Snmp(transport); transport.listen(); } /** * 向管理进程发送Trap报文 * * @throws IOException */ public void sendPDU() throws IOException { // 设置 target CommunityTarget target = new CommunityTarget(); target.setAddress(targetAddress); // 通讯不成功时的重试次数 target.setRetries(2); // 超时时间 target.setTimeout(1500); // snmp版本 target.setVersion(SnmpConstants.version2c); // 建立 PDU PDU pdu = new PDU(); pdu.add(new VariableBinding(new OID(".1.3.6.1.2.3377.10.1.1.1.1"), new OctetString("SnmpTrap"))); pdu.add(new VariableBinding(new OID(".1.3.6.1.2.3377.10.1.1.1.2"), new OctetString("JavaEE"))); pdu.setType(PDU.TRAP); // 向Agent发送PDU，并接收Response ResponseEvent respEvnt = snmp.send(pdu, target); // 解析Response if (respEvnt != null && respEvnt.getResponse() != null) { Vector<VariableBinding> recVBs = respEvnt.getResponse() .getVariableBindings(); for (int i = 0; i < recVBs.size(); i++) { VariableBinding recVB = recVBs.elementAt(i); System.out.println(recVB.getOid() + " : " + recVB.getVariable()); } } } public static void main(String[] args) { try { SnmpUtilSendTrap util = new SnmpUtilSendTrap(); util.initComm(); util.sendPDU(); } catch (IOException e) { e.printStackTrace(); } } } 测试

一、运行MultiThreadedTrapReceiver类，提示“开始监听Trap信息!”并处理监听状态this

二、运行SnmpUtilSendTrap类，运行完毕后，将会在“开始监听Trap信息!”后面显示：spa

1.3.6.1.2.3377.10.1.1.1.1 : SnmpTrap
1.3.6.1.2.3377.10.1.1.1.2 : JavaEE操作系统

MultiThreadedTrapReceiver输出面板中显示以上两行即表示测试成功！.net

说明：代理
