借助Sigar API获取网络信息

迈不过友情╰ 2022-08-07 02:43 207阅读 0赞

Sigar（全称System Information Gatherer And Reporter，即系统信息收集报表器），它提供了一个开源的跨平台的收集计算机硬件和操作系统信息的API（该API底层接口用C语言编写），本文将演示如何借助Sigar API获取网络信息：

package com.ghj.packageoftest;
    
    import org.hyperic.sigar.NetFlags;
    import org.hyperic.sigar.NetInterfaceConfig;
    import org.hyperic.sigar.NetInterfaceStat;
    import org.hyperic.sigar.Sigar;
    import org.hyperic.sigar.SigarException;

    public class NetworkTool {
    
    	public static void main(String[] args) throws SigarException {
    		Sigar sigar = new Sigar();
    
    		// 当前机器的正式域名
    		try {
    			System.out.println(sigar.getFQDN());// 即Fully Qualified Domain Name，中文为：全称域名
    		} catch (SigarException e) {
    			e.printStackTrace();
    		}
    
    		String[] netInterfaceList = sigar.getNetInterfaceList();
    
    		// 获取网络流量信息
    		for (int i = 0; i < netInterfaceList.length; i++) {
    			String netInterface = netInterfaceList[i];// 网络接口
    			System.out.println("netInterface：" + netInterface);
    			NetInterfaceConfig netInterfaceConfig = sigar.getNetInterfaceConfig(netInterface);
    			System.out.println("Address = " + netInterfaceConfig.getAddress());// IP地址
    			System.out.println("Netmask = " + netInterfaceConfig.getNetmask());// 子网掩码
    			if ((netInterfaceConfig.getFlags() & 1L) <= 0L) {// 网络装置是否正常启用
    				System.out.println("!IFF_UP...skipping getNetInterfaceStat");
    				continue;
    			}
    			NetInterfaceStat netInterfaceStat = sigar.getNetInterfaceStat(netInterface);
    			System.out.println("netInterfaceStat rxPackets：" + netInterfaceStat.getRxPackets());// 接收的总包裹数
    			System.out.println("netInterfaceStat txPackets：" + netInterfaceStat.getTxPackets());// 发送的总包裹数

    			System.out.println("netInterfaceStat rxErrors：" + netInterfaceStat.getRxErrors());// 接收到的错误包数
    			System.out.println("netInterfaceStat txErrors：" + netInterfaceStat.getTxErrors());// 发送数据包时的错误数
    			System.out.println("netInterfaceStat rxDropped：" + netInterfaceStat.getRxDropped());// 接收时丢弃的包数
    			System.out.println("netInterfaceStat txDropped：" + netInterfaceStat.getTxDropped());// 发送时丢弃的包数
    			System.out.println("netInterfaceStat rxOverruns：" + netInterfaceStat.getRxOverruns());
    			System.out.println("netInterfaceStat txOverruns：" + netInterfaceStat.getTxOverruns());
    			System.out.println("netInterfaceStat rxFrame：" + netInterfaceStat.getRxFrame());
    			System.out.println("netInterfaceStat txCollisions：" + netInterfaceStat.getTxCollisions());
    			System.out.println("netInterfaceStat txCarrier：" + netInterfaceStat.getTxCarrier());
    			System.out.println("netInterfaceStat speed：" + netInterfaceStat.getSpeed());
    		}
    
    		// 一些其它的信息
    		for (int i = 0; i < netInterfaceList.length; i++) {
    			String netInterface = netInterfaceList[i];// 网络接口
    			NetInterfaceConfig netInterfaceConfig = sigar.getNetInterfaceConfig(netInterface);
    			if (NetFlags.LOOPBACK_ADDRESS.equals(netInterfaceConfig.getAddress())
    				|| (netInterfaceConfig.getFlags() & NetFlags.IFF_LOOPBACK) != 0
    				|| NetFlags.NULL_HWADDR.equals(netInterfaceConfig.getHwaddr())) {
    				continue;
    			}
    
    			System.out.println("netInterfaceConfig name：" + netInterfaceConfig.getName());
    			System.out.println("netInterfaceConfig hwaddr：" + netInterfaceConfig.getHwaddr());// 网卡MAC地址
    			System.out.println("netInterfaceConfig type:" + netInterfaceConfig.getType());
    			System.out.println("netInterfaceConfig description：" + netInterfaceConfig.getDescription());// 网卡描述信息
    			System.out.println("netInterfaceConfig address：" + netInterfaceConfig.getAddress());// IP地址
    			System.out.println("netInterfaceConfig destination：" + netInterfaceConfig.getDestination());
    			System.out.println("netInterfaceConfig broadcast：" + netInterfaceConfig.getBroadcast());// 网关广播地址
    			System.out.println("netInterfaceConfig netmask：" + netInterfaceConfig.getNetmask());// 子网掩码
    			System.out.println("netInterfaceConfig flags：" + netInterfaceConfig.getFlags());

    			System.out.println("netInterfaceConfig metric：" + netInterfaceConfig.getMetric());
    		}
    		sigar.close();
    	}
