window+ubuntu下服務器狀態監控

一： window環境下

dll 文件： sigar-amd64-winnt.dll 或 sigar-x86-winnt.dll

jar包：sigar.jar

二： ubuntu環境下

so文件： libsigar-amd64-linux.so 或 libsigar-x86-linux.so

jar包： sigar.jar

三：代碼如下

public class CoreMonitorQdeAction{
static Sigar sigar = new Sigar();

@Privilege
public synchronized ObjectNode getMonitorData(ActionContext ctx) throws SigarException{
ObjectNode model = JsonNodeFactory.instance.objectNode();
ArrayNode records = JsonNodeFactory.instance.arrayNode();
CpuPerc cpu = sigar.getCpuPerc();
Mem mem = sigar.getMem();

model.put("cpuIdle", (int)(cpu.getIdle()*100.0));

ObjectNode o = records.addObject();
o.put("phyTotal", mem.getTotal()/1024/1024);
o.put("phyUsed", mem.getUsed()/1024/1024);
o.put("jvmMax", Runtime.getRuntime().maxMemory()/1024/1024);

o.put("jvmUsed", (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory())/1024/1024);
model.put("mem",o);
long netflow = 0;
String ifNames[] = sigar.getNetInterfaceList();
for (int i = 0; i < ifNames.length; i++) {
String name = ifNames[i];
NetInterfaceConfig ifconfig = sigar.getNetInterfaceConfig(name);

if ( (ifconfig.getFlags() & 1L) <= 0L) {
continue;
}
NetInterfaceStat ifstat = sigar.getNetInterfaceStat(name);
netflow += ifstat.getRxBytes()/1024;
netflow += ifstat.getTxBytes()/1024;
}
model.put("netflow",netflow);
long [] procList = sigar.getProcList();

ArrayNode ar = JsonNodeFactory.instance.arrayNode();
for(long pid : procList){
//if("<unknown>".equals(p.getName()) || "<unknown>".equals(p.getOwner()))continue;
try{
o = records.addObject();
o.put("pid",pid);
String name = sigar.getProcExe(pid).getName();
int index = name.lastIndexOf('\\');
if(index<0)index = name.lastIndexOf('/');
if(index>=0)o.put("name",name.substring(index + 1));
o.put("mem", sigar.getProcMem(pid).getResident()/1024/1024);
o.put("cpuTime",(int)(sigar.getProcCpu(pid).getPercent()*100.0));
ar.add(o);
}catch(Exception e){

}
}
model.put("processes", ar);
model.put("timestamp",new Date().getTime());
return model;
}

}

以下爲轉載內容

通過Hyperic-hq產品的基礎包sigar.jar來實現服務器狀態數據的獲取。Sigar.jar包是通過本地方法來調用操作系統API來獲取系統相關數據。Windows操作系統下Sigar.jar依賴sigar-amd64-winnt.dll或sigar-x86-winnt.dll，linux 操作系統下則依賴libsigar-amd64-linux.so或libsigar-x86-linux.so……而Sigar.jar還依賴於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下載地址：http://sigar.hyperic.com

Sigar.jar包的使用方法：

1、 CPU資源信息

a) CPU數量（單位：個）

privatestaticint getCpuCount() throws SigarException {

Sigar sigar = new Sigar();

try {

return sigar.getCpuInfoList().length;

} finally {

sigar.close();

}

b) CPU的總量（單位：HZ）及CPU的相關信息

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都適用

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的類別，如：Celeron

traceln("cache size=" + info.getCacheSize());//緩衝存儲器數量

}

c) CPU的用戶使用量、系統使用剩餘量、總的剩餘量、總的使用佔用量等（單位：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都適用

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()));// 用戶使用率

println("Sys :" + CpuPerc.format(cpu.getSys()));// 系統使用率

println("Wait :" + CpuPerc.format(cpu.getWait()));// 當前等待率

println("Nice :" + CpuPerc.format(cpu.getNice()));//

println("Idle :" + CpuPerc.format(cpu.getIdle()));// 當前空閒率

println("Total :" + CpuPerc.format(cpu.getCombined()));// 總的使用率

}

d) ……

2、內存資源信息

a) 物理內存信息

Sigar sigar = new Sigar();

Mem mem = sigar.getMem();

// 內存總量

System.out.println("Total = " + mem.getTotal() / 1024L + "K av");

// 當前內存使用量

System.out.println("Used = " + mem.getUsed() / 1024L + "K used");

// 當前內存剩餘量

System.out.println("Free = " + mem.getFree() / 1024L + "K free");

b) 系統頁面文件交換區信息

Sigar sigar = new Sigar();

Swap swap = sigar.getSwap();

// 交換區總量

System.out.println("Total = " + swap.getTotal() / 1024L + "K av");

// 當前交換區使用量

System.out.println("Used = " + swap.getUsed() / 1024L + "K used");

// 當前交換區剩餘量

System.out.println("Free = " + swap.getFree() / 1024L + "K free");

c) ……

3、操作系統信息

a) 取到當前操作系統的名稱：

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) 取當前操作系統的信息

publicvoid testGetOSInfo() {

OperatingSystem OS = OperatingSystem.getInstance();

// 操作系統內核類型如： 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());

System.out.println("OS.getMachine() = " + OS.getMachine());//

// 操作系統類型

System.out.println("OS.getName() = " + OS.getName());

System.out.println("OS.getPatchLevel() = " + OS.getPatchLevel());//

// 操作系統的賣主

System.out.println("OS.getVendor() = " + OS.getVendor());

// 賣主名稱

System.out.println("OS.getVendorCodeName() = " + OS.getVendorCodeName());

// 操作系統名稱

System.out.println("OS.getVendorName() = " + OS.getVendorName());

// 操作系統賣主類型

System.out.println("OS.getVendorVersion() = " + OS.getVendorVersion());

// 操作系統的版本號

System.out.println("OS.getVersion() = " + OS.getVersion());

}

c) 取當前系統進程表中的用戶信息

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());

//當前系統進程表中的用戶名

Sysout.out.println ("getUser() = " + _who.getUser());

}

} catch (SigarException e) {

e.printStackTrace();

}

d) ……

4、資源信息（主要是硬盤）

a) 取硬盤已有的分區及其詳細信息（通過sigar.getFileSystemList()來獲得FileSystem列表對象，然後對其進行編歷）：

publicvoid testFileSystemInfo() throws Exception {

Sigar sigar = getSigar();

FileSystem fslist[] = sigar.getFileSystemList();

String dir = System.getProperty("user.home");//當前用戶文件夾路徑

for (int i = 0; i < fslist.length; i++) {

System.out.println("/n~~~~~~~~~~" + i + "~~~~~~~~~~");

FileSystem fs = fslist[i];

// 分區的盤符名稱

System.out.println("fs.getDevName() = " + fs.getDevName());

// 分區的盤符名稱

System.out.println("fs.getDirName() = " + fs.getDirName());

System.out.println("fs.getFlags() = " + fs.getFlags());//

// 文件系統類型，比如 FAT32、NTFS

System.out.println("fs.getSysTypeName() = " + fs.getSysTypeName());

// 文件系統類型名，比如本地硬盤、光驅、網絡文件系統等

System.out.println("fs.getTypeName() = " + fs.getTypeName());

// 文件系統類型

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 : 本地硬盤

// 文件系統總大小

System.out.println(" Total = " + usage.getTotal() + "KB");

// 文件系統剩餘大小

System.out.println(" Free = " + usage.getFree() + "KB");

// 文件系統可用大小

System.out.println(" Avail = " + usage.getAvail() + "KB");

// 文件系統已經使用量

System.out.println(" Used = " + usage.getUsed() + "KB");

double usePercent = usage.getUsePercent() * 100D;

// 文件系統資源的利用率

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;

case 6:// TYPE_SWAP ：頁面交換

break;

}

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

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

}

return;

}

b) ……

5、網絡信息

a) 當前機器的正式域名

public String getFQDN(){

try {

return InetAddress.getLocalHost().getCanonicalHostName();

} catch (UnknownHostException e) {

try {

Sigar sigar = new Sigar();

return sigar.getFQDN();

} catch (SigarException ex) {

returnnull;

} finally {

sigar.close();

}

b) 取到當前機器的IP地址

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地址時就返回

// 否則再通過Sigar工具包中的方法來獲取

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) 取到當前機器的MAC地址

public String getMAC() {

Sigar sigar = null;

try {

sigar = new Sigar();

String[] ifaces = sigar.getNetInterfaceList();

String hwaddr = null;

for (int i = 0; i < ifaces.length; i++) {

NetInterfaceConfig cfg = sigar.getNetInterfaceConfig(ifaces[i]);

if (NetFlags.LOOPBACK_ADDRESS.equals(cfg.getAddress())

|| (cfg.getFlags() & NetFlags.IFF_LOOPBACK) != 0

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

continue;

}

/*如果存在多張網卡包括虛擬機的網卡，默認只取第一張網卡的MAC地址，如果要返回所有的網卡（包括物理的和虛擬的）則可以修改方法的返回類型爲數組或Collection，通過在for循環裏取到的多個MAC地址。*/

hwaddr = cfg.getHwaddr();

break;

}

return hwaddr != null ? hwaddr : null;

} catch (Exception e) {

returnnull;

} finally {

if (sigar != null)

sigar.close();

}

d) 根據MAC地址來獲得一個GUID號

public String getGUID(String mac) {

if (mac == null)

returnnull;

EthernetAddress eAddr = new EthernetAddress(mac);

return UUIDGenerator.getInstance().generateTimeBasedUUID(eAddr)

.toString();

}

e) 獲取網絡流量等信息

publicvoid testNetIfList() throws Exception {

Sigar sigar = new Sigar();

String ifNames[] = sigar.getNetInterfaceList();

for (int i = 0; i < ifNames.length; i++) {

String name = ifNames[i];

NetInterfaceConfig ifconfig = sigar.getNetInterfaceConfig(name);

print("/nname = " + name);//網絡設備名

print("Address = "+ ifconfig.getAddress());//IP地址

print("Netmask = "+ ifconfig.getNetmask());//子網掩碼

if ( (ifconfig.getFlags() & 1L) <= 0L) {

print("!IFF_UP...skipping getNetInterfaceStat");

continue;

}

try {

NetInterfaceStat ifstat = sigar.getNetInterfaceStat(name);

print("RxPackets = " + ifstat.getRxPackets());//接收的總包裹數

print("TxPackets = " + ifstat.getTxPackets());//發送的總包裹數

print("RxBytes = " + ifstat.getRxBytes());//接收到的總字節數

print("TxBytes = " + ifstat.getTxBytes());//發送的總字節數

print("RxErrors = " + ifstat.getRxErrors());//接收到的錯誤包數

print("TxErrors = " + ifstat.getTxErrors());//發送數據包時的錯誤數

print("RxDropped = " + ifstat.getRxDropped());//接收時丟棄的包數

print("TxDropped = " + ifstat.getTxDropped());//發送時丟棄的包數

} catch (SigarNotImplementedException e) {

} catch (SigarException e) {

print(e.getMessage());

}

void print(String msg){

System.out.println(msg);

}

f) 一些其他的信息

privatevoid getEthernetInfo(){

Sigar sigar = null;

try {

sigar = new Sigar();

String[] ifaces = sigar.getNetInterfaceList();

for (int i = 0; i < ifaces.length; i++) {

NetInterfaceConfig cfg = sigar.getNetInterfaceConfig(ifaces[i]);

if (NetFlags.LOOPBACK_ADDRESS.equals(cfg.getAddress())

|| (cfg.getFlags() & NetFlags.IFF_LOOPBACK) != 0

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

continue;

}

System.out.println("cfg.getAddress() = " + cfg.getAddress());//IP地址
