  • 采集服务器信息

    引用:http://blog.csdn.net/ocelight/article/details/4147278

    通过Hyperic-hq产品的基础包sigar.jar来实现服务器状态数据的获取。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 {
             return sigar.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
               CpuPerc cpu;
               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
               CpuPerc cpuList[] = 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 String getPlatformName() {
               String hostname = "";
               try {
                   hostname = InetAddress.getLocalHost().getHostName();
               } catch (Exception exc) {
                   Sigar sigar = 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() {
               OperatingSystem OS = OperatingSystem.getInstance();
               // 操作系统内核类型如: 386486586x86
               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("/n~~~~~~~~~" + String.valueOf(i) + "~~~~~~~~~");
                          Who _who = who[i];
                          Sysout.out.println ("getDevice() = " + _who.getDevice());
                          Sysout.out.println ("getHost() = " + _who.getHost());
                          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) {

                   System.out.println("/n~~~~~~~~~~" + i + "~~~~~~~~~~");
                   FileSystem fs = 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.getDirName() = " + fs.getDirName());
                   System.out.println("fs.getFlags() = " + fs.getFlags());//
                   // 文件系统类型,比如 FAT32NTFS
                   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;
