  • Hyperic-Sigar简介——检测与监控

    http://blog.csdn.net/liyong199012/article/details/20302761

    Hyperic-Sigar是一个收集系统各项底层信息的工具集.他有如下特点:
    1. 收集信息全面
    收集CPU,MEM,NETWORK,PROCESS,IOSTAT等
    使用Sigar,你完全可以模仿出cpuinfo,meminfo,top,free,ifconfig,ipconfig,netstat,route,df,du,ps,ls等多种unix平台和windows平台的指令.
    2.跨平台,支持多数平台
    支持的平台包括:windows系列(32系列,IA64系列,AMD64系列),Linux系列,freeBsd系列,HPUnix系列,Sun solaris/Sparc/Sparc64系列,macOs系列,AIX系列等
    3.提供的API接口全面
    sigar本身由C语言开发而成,提供了丰富的API接口,包括:Java,.NET,PERL,PHP,Python,RUBY.Sigar.jar包是通过本地方法来调用操作系统API来获取系统相关数据。Windows操作系统下Sigar.jar依赖sigar-amd64-winnt.dll或sigar-x86-winnt.dll,linux操作系统下则依赖libsigar-amd64-linux.so或libsigar-x86-linux.so……而Sigar.jar还依赖于jug-asl-2.0.0.jar、log4j-1.2.14.jar、Junit.jar,

    Sigar.jar包的使用方法:
     
    1、             CPU资源信息
    a)        CPU数量(单位:个)
    privatestaticint getCpuCount()throws SigarException {
        Sigar sigar = new Sigar();
        try {
            returnsigar.getCpuInfoList().length;
        } finally {
            sigar.close();
        }
    }
    b)       CPU的总量(单位:HZ)及CPU的相关信息
    Sigar sigar = getSigar();
          CpuInfo infos[] = sigar.getCpuInfoList();
          for (int i = 0; i< infos.length; i++){//不管是单块CPU还是多CPU都适用
              CpuInfo info = infos[i];
              traceln("mhz=" +info.getMhz());//CPU的总量MHz
              traceln("vendor=" +info.getVendor());//获得CPU的卖主,如:Intel
              traceln("model=" +info.getModel());//获得CPU的类别,如:Celeron
              traceln("cache size=" +info.getCacheSize());//缓冲存储器数量
    }
    c)        CPU的用户使用量、系统使用剩余量、总的剩余量、总的使用占用量等(单位:100%)
    publicvoid testCpuPerc() {
              Sigar sigar= new Sigar();
             // 方式一,主要是针对一块CPU的情况
              CpuPerccpu;
             try {
                  cpu =sigar.getCpuPerc();
                 printCpuPerc(cpu);
              }catch (SigarException e) {
                 e.printStackTrace();
              }
             //方式二,不管是单块CPU还是多CPU都适用
              CpuPerccpuList[] = null;
             try {
                  cpuList =sigar.getCpuPercList();
              }catch (SigarException e) {
                 e.printStackTrace();
                 return;
              }
             for (int i = 0; i< cpuList.length; i++) {
                 printCpuPerc(cpuList[i]);
              }
           }
          privatevoid printCpuPerc(CpuPerc cpu) {
             println("User :" +CpuPerc.format(cpu.getUser()));//用户使用率
             println("Sys :" +CpuPerc.format(cpu.getSys()));// 系统使用率
             println("Wait :" +CpuPerc.format(cpu.getWait()));//当前等待率
             println("Nice :" +CpuPerc.format(cpu.getNice()));//
             println("Idle :" +CpuPerc.format(cpu.getIdle()));//当前空闲率
             println("Total :" +CpuPerc.format(cpu.getCombined()));//总的使用率
    }
    d)       ……
    2、             内存资源信息
    a)       物理内存信息
    Sigar sigar = new Sigar();
    Mem mem = sigar.getMem();
    // 内存总量
          System.out.println("Total = " +mem.getTotal() / 1024L + "K av");
          // 当前内存使用量
          System.out.println("Used = " +mem.getUsed() / 1024L + "K used");
          // 当前内存剩余量
    System.out.println("Free = "+ mem.getFree() / 1024L + "K free");
    b)       系统页面文件交换区信息
    Sigar sigar = new Sigar();
    Swap swap = sigar.getSwap();
    // 交换区总量
          System.out.println("Total = " +swap.getTotal() / 1024L + "K av");
          // 当前交换区使用量
          System.out.println("Used = " +swap.getUsed() / 1024L + "K used");
          // 当前交换区剩余量
    System.out.println("Free = "+ swap.getFree() / 1024L + "K free");
    c)     ……
    3、             操作系统信息
    a)     取到当前操作系统的名称:
     private StringgetPlatformName() {
              Stringhostname = "";
             try {
                  hostname =InetAddress.getLocalHost().getHostName();
              }catch (Exception exc) {
                  Sigarsigar = new Sigar();
                 try {
                     hostname= sigar.getNetInfo().getHostName();
                  }catch (SigarException e) {
                     hostname= "localhost.unknown";
                  }finally {
                    sigar.close();
                  }
              }
             return hostname;
    }
    b)       取当前操作系统的信息
          publicvoid testGetOSInfo() {
             OperatingSystemOS =OperatingSystem.getInstance();
             // 操作系统内核类型如:386、486、586等x86
             System.out.println("OS.getArch() =" + OS.getArch());
             System.out.println("OS.getCpuEndian() =" + OS.getCpuEndian());//
             System.out.println("OS.getDataModel() =" + OS.getDataModel());//
             // 系统描述
             System.out.println("OS.getDescription()= " + OS.getDescription());
             System.out.println("OS.getMachine() =" + OS.getMachine());//
             // 操作系统类型
             System.out.println("OS.getName() =" + OS.getName());
             System.out.println("OS.getPatchLevel()= " + OS.getPatchLevel());//
             // 操作系统的卖主
             System.out.println("OS.getVendor() =" + OS.getVendor());
             // 卖主名称
             System.out.println("OS.getVendorCodeName()= " + OS.getVendorCodeName());
             // 操作系统名称
             System.out.println("OS.getVendorName()= " + OS.getVendorName());
             // 操作系统卖主类型
             System.out.println("OS.getVendorVersion()= " + OS.getVendorVersion());
             // 操作系统的版本号
             System.out.println("OS.getVersion() =" + OS.getVersion());
    }
    c)        取当前系统进程表中的用户信息
    publicvoid testWho() {
             try {
                  Sigar sigar= new Sigar();
                  Who who[] =sigar.getWhoList();
                 if (who != null&& who.length> 0) {
                    for (int i = 0; i< who.length; i++) {
                        Sysout.out.println("
    ~~~~~~~~~" +String.valueOf(i) + "~~~~~~~~~");
                         Who _who =who[i];

    }
    d)       ……
    4、             资源信息(主要是硬盘)
    a)     取硬盘已有的分区及其详细信息(通过sigar.getFileSystemList()来获得FileSystem列表对象,然后对其进行编历):
    publicvoid testFileSystemInfo()throws Exception {
              Sigar sigar= getSigar();
              FileSystemfslist[] = sigar.getFileSystemList();
              String dir =System.getProperty("user.home");//当前用户文件夹路径
             for (int i = 0; i< fslist.length; i++) {
                 System.out.println("
    ~~~~~~~~~~"+ i + "~~~~~~~~~~");
                  FileSystemfs = fslist[i];
                 // 分区的盘符名称
                 System.out.println("fs.getDevName() =" + fs.getDevName());
                 // 分区的盘符名称

                 System.out.println("fs.getFlags() =" + fs.getFlags());//
                 // 文件系统类型,比如 FAT32、NTFS
                 System.out.println("fs.getSysTypeName()= " + fs.getSysTypeName());
                 // 文件系统类型名,比如本地硬盘、光驱、网络文件系统等
                 System.out.println("fs.getTypeName() =" + fs.getTypeName());
                 // 文件系统类型
                 System.out.println("fs.getType() =" + fs.getType());
                 FileSystemUsage usage = null;
                 try {
                     usage =sigar.getFileSystemUsage(fs.getDirName());
                  }catch (SigarException e) {
                    if (fs.getType() == 2)
                        throw e;
                    continue;
                  }
                 switch (fs.getType()) {
                 case 0: // TYPE_UNKNOWN:未知
                    break;
                 case 1: // TYPE_NONE
                    break;
                 case 2: // TYPE_LOCAL_DISK :本地硬盘
                    // 文件系统总大小
                    System.out.println(" Total= " + usage.getTotal() + "KB");
                    // 文件系统剩余大小
                    System.out.println(" Free= " + usage.getFree() + "KB");
                    // 文件系统可用大小
                    System.out.println(" Avail= " + usage.getAvail() + "KB");
                    // 文件系统已经使用量
                    System.out.println(" Used= " + usage.getUsed() + "KB");
                    double usePercent = usage.getUsePercent() *100D;
                    // 文件系统资源的利用率
                    System.out.println(" Usage= " + usePercent + "%");
    break;
                 case 3:// TYPE_NETWORK:网络
                    break;
                 case 4:// TYPE_RAM_DISK:闪存
                    break;
                 case 5:// TYPE_CDROM :光驱

                  }
                 System.out.println(" DiskReads= " + usage.getDiskReads());
                 System.out.println(" DiskWrites= " + usage.getDiskWrites());
              }
             return;
    }
    b)     ……
    5、             网络信息
    a)     当前机器的正式域名
    public StringgetFQDN(){
             try {

    b)       取到当前机器的IP地址
    public StringgetDefaultIpAddress() {
               String address = null;
               try {
                   address =InetAddress.getLocalHost().getHostAddress();
                   //没有出现异常而正常当取到的IP时,如果取到的不是网卡循回地址时就返回
                 // 否则再通过Sigar工具包中的方法来获取
    if(!NetFlags.LOOPBACK_ADDRESS.equals(address)){
                        return address;
                   }

                            ||(cfg.getFlags() &NetFlags.IFF_LOOPBACK) != 0
                            ||NetFlags.NULL_HWADDR.equals(cfg.getHwaddr())){
                        continue;
