服务器性能监控之WMI / iVAN

1.WMI简介
WMI是英文WindowsManagementInstrumentation的简写，通过使用WMI，我们可以获取本地或远程服务器的性能参数和进程运行情况，以及大部分硬件信息，但前提是运行的用户要有足够的权限，如administrator组用户等。这也是做负载均衡所需要且比较方便快捷的途径。

2.使用时首先添加System.Management.dll，然后引用

usingSystem.Management;

3.定义远程访问

publicclassManagementConnectPool
...{
privatestaticSystem.Management.ConnectionOptionsConn=newConnectionOptions();
privatestaticManagementObjectSearchermos=newManagementObjectSearcher();
privatestringusername="";
privatestringpwd="";
privatestringspace="";
privatestringserver="";

publicManagementConnectPool(stringmpusername,stringmppwd,stringmpspace,stringmpserver)
...{
this.username=mpusername;
this.pwd=mppwd;
this.space=mpspace;
this.server=mpserver;
Conn.Username=mpusername;
Conn.Password=mppwd;
stringscopestring="//"+mpserver+mpspace;
System.Management.ManagementScopeMs=newManagementScope(scopestring);
Ms.Connect();
mos.Scope=Ms;
}

publicManagementObjectCollectiongetQueryResult(stringqueryString)
...{
ObjectQueryoq=newObjectQuery();
oq.QueryString=queryString;
mos.Query=oq;
ManagementObjectCollectionmoc=mos.Get();
returnmoc;
}
}

4.获取CPU，内存，网络流量等信息

publicclassMonitor
...{
privatestringusername="";
privatestringpwd="";
privatestringip="";
ManagementConnectPoolmcp;
WMSServerClassserver;

publicMonitor(stringusername,stringpwd,stringip)...{
this.username=username;
this.pwd=pwd;
this.ip=ip;
mcp=newManagementConnectPool(username,pwd,"/root/cimv2",ip);
server=newWMSServerClass();
}

WMI方式获取网卡流量#regionWMI方式获取网卡流量
privatevoidgetNetWorkFlow()
...{
ManagementObjectCollectionmoc=mcp.getQueryResult(@"select*fromWin32_NetworkAdapterwheremacaddress<>nullandmanufacturer<>'Microsoft'");
string[]list=newstring[moc.Count];
foreach(System.Management.ManagementObjectmymacinmoc)
...{
stringa=mymac["Speed"].ToString();//nullWMI未实现该属性
Console.WriteLine(a.ToString());
}
}

string[]list=newstring[moc.Count];
inti=0;
foreach(ManagementObjectmoinmoc)
...{
stringtotal=mo.GetPropertyValue("LoadPercentage").ToString();
list[i]=total;
i++;
}
}
#endregion

publicstringgetMemoryUsage()
...{
ManagementObjectCollectionmoc=mcp.getQueryResult("select*fromWin32_LogicalMemoryConfiguration");
inttotalm=1;intavilablem=1;
foreach(ManagementObjectmoinmoc)
...{
stringtotal=mo.GetPropertyValue("TotalPhysicalMemory").ToString();
totalm=int.Parse(total);
}
moc=mcp.getQueryResult("select*fromWin32_PerfRawData_PerfOS_Memory");
foreach(ManagementObjectmoinmoc)
...{
stringavilable=mo.GetPropertyValue("AvailableKBytes").ToString();
avilablem=int.Parse(avilable);
}
intusedm=totalm-avilablem;
doublememoryusage=(double)usedm*(double)100/(double)totalm;
returnmemoryusage.ToString();
}
#endregion
}

通过上面介绍的方法，可以很轻松的获取远程或本地机器的性能，进程和硬件信息等。另外：WMI也可以通过使用Vbscript等脚本调用。
