通過Hyperic-hq産品的基礎包sigar.jar來實作伺服器狀态資料的擷取。Sigar.jar包是通過本地方法來調用作業系統API來擷取系統相關資料。Windows作業系統下Sigar.jar依賴sigar-amd64-winnt.dll或sigar-x86-winnt.dll，linux 作業系統下則依賴libsigar-amd64-linux.so或libsigar-x86-linux.so……而Sigar.jar還依賴于jug-asl-2.0.0.jar、log4j-1.2.14.jar、Junit.jar， Hyperic-hq官方網站：http://www.hyperic.com Sigar.jar下載下傳位址：https://support.hyperic.com/display/SIGAR/Home 下載下傳的源碼包中有各種語言的example: Sigar.jar包的使用方法： 1、 CPU資源資訊 a) CPU數量（機關：個） privatestaticint getCpuCount() throws SigarException { Sigar sigar = new Sigar(); try { return sigar.getCpuInfoList().length; } finally { sigar.close(); } } b) CPU的總量（機關：HZ）及CPU的相關資訊 Sigar sigar = getSigar(); CpuInfo infos[] = sigar.getCpuInfoList(); for (int i = 0; i < infos.length; i++) {//不管是單塊CPU還是多CPU都适用 CpuInfo info = infos[i]; traceln("mhz=" + info.getMhz());//CPU的總量MHz traceln("vendor=" + info.getVendor());//獲得CPU的賣主，如：Intel traceln("model=" + info.getModel());//獲得CPU的類别，如：Celeron traceln("cache size=" + info.getCacheSize());//緩沖存儲器數量 } c) CPU的使用者使用量、系統使用剩餘量、總的剩餘量、總的使用占用量等（機關：100%） publicvoid testCpuPerc() { Sigar sigar = new Sigar(); // 方式一，主要是針對一塊CPU的情況 CpuPerc cpu; try { cpu = sigar.getCpuPerc(); printCpuPerc(cpu); } catch (SigarException e) { e.printStackTrace(); } // 方式二，不管是單塊CPU還是多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()));// 使用者使用率 println("Sys :" + CpuPerc.format(cpu.getSys()));// 系統使用率 println("Wait :" + CpuPerc.format(cpu.getWait()));// 目前等待率 println("Nice :" + CpuPerc.format(cpu.getNice()));// println("Idle :" + CpuPerc.format(cpu.getIdle()));// 目前空閑率 println("Total :" + CpuPerc.format(cpu.getCombined()));// 總的使用率 } d) …… 2、 記憶體資源資訊 a) 實體記憶體資訊 Sigar sigar = new Sigar(); Mem mem = sigar.getMem(); // 記憶體總量 System.out.println("Total = " + mem.getTotal() / 1024L + "K av"); // 目前記憶體使用量 System.out.println("Used = " + mem.getUsed() / 1024L + "K used"); // 目前記憶體剩餘量 System.out.println("Free = " + mem.getFree() / 1024L + "K free"); b) 系統頁面檔案交換區資訊 Sigar sigar = new Sigar(); Swap swap = sigar.getSwap(); // 交換區總量 System.out.println("Total = " + swap.getTotal() / 1024L + "K av"); // 目前交換區使用量 System.out.println("Used = " + swap.getUsed() / 1024L + "K used"); // 目前交換區剩餘量 System.out.println("Free = " + swap.getFree() / 1024L + "K free"); c) …… 3、 作業系統資訊 a) 取到目前作業系統的名稱： 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) 取目前作業系統的資訊 publicvoid testGetOSInfo() { OperatingSystem OS = OperatingSystem.getInstance(); // 作業系統核心類型如： 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());// // 系統描述 System.out.println("OS.getDescription() = " + OS.getDescription());

// 賣主名稱 System.out.println("OS.getVendorCodeName() = " + OS.getVendorCodeName()); // 作業系統名稱 System.out.println("OS.getVendorName() = " + OS.getVendorName()); // 作業系統賣主類型 System.out.println("OS.getVendorVersion() = " + OS.getVendorVersion()); // 作業系統的版本号 System.out.println("OS.getVersion() = " + OS.getVersion()); } c) 取目前系統程序表中的使用者資訊 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()); //目前系統程序表中的使用者名 Sysout.out.println ("getUser() = " + _who.getUser()); } } } catch (SigarException e) { e.printStackTrace(); } } d) …… 4、 資源資訊（主要是硬碟） a) 取硬碟已有的分區及其詳細資訊（通過sigar.getFileSystemList()來獲得FileSystem清單對象，然後對其進行編曆）： publicvoid testFileSystemInfo() throws Exception { Sigar sigar = getSigar();

} 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 : 本地硬碟 // 檔案系統總大小 System.out.println(" Total = " + usage.getTotal() + "KB"); // 檔案系統剩餘大小 System.out.println(" Free = " + usage.getFree() + "KB"); // 檔案系統可用大小 System.out.println(" Avail = " + usage.getAvail() + "KB"); // 檔案系統已經使用量 System.out.println(" Used = " + usage.getUsed() + "KB"); double usePercent = usage.getUsePercent() * 100D; // 檔案系統資源的使用率 System.out.println(" Usage = " + usePercent + "%"); break; case 3:// TYPE_NETWORK ：網絡 break; case 4:// TYPE_RAM_DISK ：閃存 break; case 5:// TYPE_CDROM ：光驅 break;

} catch (UnknownHostException e) { try { Sigar sigar = new Sigar(); return sigar.getFQDN(); } catch (SigarException ex) { returnnull; } finally { sigar.close(); } } } b) 取到目前機器的IP位址 public String getDefaultIpAddress() { String address = null; try { address = InetAddress.getLocalHost().getHostAddress(); // 沒有出現異常而正常當取到的IP時，如果取到的不是網卡循回位址時就傳回 // 否則再通過Sigar工具包中的方法來擷取 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) { address = NetFlags.LOOPBACK_ADDRESS; } finally { sigar.close(); } return address; } c) 取到目前機器的MAC位址 public String getMAC() { Sigar sigar = null;
