Hyperic-Sigar简介

Posted 2020-06-10

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("\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) {

             e.printStackTrace();

          }

}

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("\n~~~~~~~~~~"+ 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.getDirName() =" + fs.getDirName());

             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

                break;

             case 6:// TYPE_SWAP ：页面交换

                break;

              }

             System.out.println(" DiskReads= " + usage.getDiskReads());

             System.out.println(" DiskWrites= " + usage.getDiskWrites());

          }

         return;

}

b)     ……

5、             网络信息

              }

          }

}

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;

               }

           } catch (UnknownHostException e) {

               //hostname not in DNS or /etc/hosts

           }

           Sigar sigar = new Sigar();

           try {

               address = sigar.getNetInterfaceConfig().getAddress();

           } catch (SigarException e) {

                        ||NetFlags.NULL_HWADDR.equals(cfg.getHwaddr())){

                    continue;

                 }

                 

                 hwaddr = cfg.getHwaddr();

                break;

              }

             return hwaddr != null ?hwaddr : null;

          }catch (Exception e) {

             returnnull;

          }finally {

             if (sigar !=null)

                sigar.close();

          }

}

d)       根据MAC地址来获得一个GUID号

public String getGUID(String mac) {

         if (mac ==null)
