Hyperic-Sigar简介——检测与监控

http://blog.****.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

          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());//

         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];

                    Sysout.out.println ("getTime() = " +_who.getTime());
                    //当前系统进程表中的用户名
                   Sysout.out.println ("getUser() = " +_who.getUser());
                 }
              }

              }catch (SigarException e) {
                if (fs.getType() == 2)
                    throw e;
                continue;
              }

             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 6:// TYPE_SWAP :页面交换
                break;
              }
             System.out.println(" DiskReads= " + usage.getDiskReads());
