查看主机的内存使用情况

这个是我在国外的一个站点上看到的使用Asp.Net得到一些系统变量的程序,
大家可以看看，其实这个程序没有多大的用处，只是说明一下asp.Net 的强大功能而已。

 1<script language="C#" runat="server">   
 2void Page_Load(Object sender, EventArgs ev)   
 3{   
 4ProcessInfo[] history = ProcessModelInfo.GetHistory(100);   
 5for( int i=0; i<history.Length; i++ )   
 6{   
 7Response.Write("StartTime:"+ history[i].StartTime.ToString() + "<BR>");   
 8Response.Write("Age:" + history[i].Age.ToString() + "<BR>");   
 9Response.Write("ProcessID:" + history[i].ProcessID.ToString() + "<BR>");   
10Response.Write("RequestCount:" + history[i].RequestCount.ToString() + "<BR>");   
11Response.Write("Status:" + GetProcessStatus(history[i].Status ) + "<BR>");   
12Response.Write("ShutdownReason:" + GetShutdownReason(history[i].ShutdownReason) + "<BR>");   
13Response.Write("PeakMemoryUsed:" + history[i].PeakMemoryUsed.ToString() + "<BR>");   
14  
15}   
16}   
17  
18public String GetProcessStatus( ProcessStatus ps )   
19{   
20String s = "Unknown";   
21if( ps == ProcessStatus.Alive )   
22s = "Alive";   
23else if( ps == ProcessStatus.ShuttingDown )   
24s = "Shutting Down";

33{   
34String s = "Unknown";
