服务器性能监控之WMI

1.WMI简介
WMI是英文Windows Management Instrumentation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
using System.Management;
3.定义远程访问
public class ManagementConnectPool
...{
private static System.Management.ConnectionOptions Conn = new ConnectionOptions() ;
private static ManagementObjectSearcher mos = new ManagementObjectSearcher();
private string username = "";
private string pwd = "";
private string space="";
private string server = "";
public ManagementConnectPool(string mpusername,string mppwd , string mpspace ,string mpserver)
...{
this.username = mpusername;
this.pwd = mppwd;
this.space = mpspace;
this.server = mpserver;
Conn.Username = mpusername;
Conn.Password = mppwd;
string scopestring ="//" + mpserver + mpspace;
System.Management.ManagementScope Ms = new ManagementScope(scopestring);
Ms.Connect();
mos.Scope = Ms;
}
public ManagementObjectCollection getQueryResult(string queryString)
...{
ObjectQuery oq = new ObjectQuery();
oq.QueryString = queryString;
mos.Query = oq;
ManagementObjectCollection moc =mos.Get();
return moc;
}
}
4.获取CPU，内存，网络流量等信息
public class Monitor
...{
private string username = "";
private string pwd ="";
private string ip = "";
ManagementConnectPool mcp;
WMSServerClass server;
public Monitor(string username,string pwd,string ip)...{
this.username = username;
this.pwd = pwd ;
this.ip = ip;
mcp = new ManagementConnectPool(username,pwd,"/root/cimv2",ip);
server = new WMSServerClass();

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。
