c# 服务器性能监控,C#服务器性能监控之WMI的代码示例详解

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();

}

{

ManagementObjectCollection moc = mcp.getQueryResult(@"select * from Win32_NetworkAdapter where macaddress<>null and manufacturer<>'Microsoft'");

string

[] list =

new

string

[moc.Count] ;

foreach

(System.Management.ManagementObject mymac

in

moc)

...

{

string

a = mymac["Speed"].ToString();

//

Console.WriteLine(a.ToString());

}

}

int

i = 0;

foreach

(ManagementObject mo

in

moc)

...

{

string

total = mo.GetPropertyValue("LoadPercentage").ToString();

list[i]=total;

i++;

}

}
