how to get total cpu utilization and RAM memory utilization in percentage.

hi all,

i am new in .NET, some body please help me regarding calculating total cpu utilization and RAM memory utilization in percentage (Accurately) on page load event of ASP.NET.

i found the following code from web, but it is not running properly and also i have no idea what it will do, i heared that there will be used performance monitoring and donot know how to use it.

please help me with coding instructins.

     public PerformanceCounter cpuCounter;

    public PerformanceCounter ramCounter;
 
      cpuCounter = new PerformanceCounter();

        cpuCounter.CategoryName = "Processor";

        cpuCounter.CounterName = "% Processor Time";

        cpuCounter.InstanceName = "_Total";
 
        ramCounter = new PerformanceCounter("Memory", "Available MBytes");
 
        /* 

        Call this method every time you need to know 

        the current cpu usage. 

        */

    }

    public string getCurrentCpuUsage()

    {

     return  cpuCounter.NextValue() + "%";

    }
 
    /* 

    Call this method every time you need to get 

    the amount of the available RAM in Mb 

    */

    public string getAvailableRAM()

    {

        return ramCounter.NextValue() + "Mb";

    }

you can get lot of information using Windows Management Instrumentation or WMI...

here is a sample code ..

Expand|Select|Wrap|Line Numbers

 
ManagementObjectSearcher searcher =new ManagementObjectSearcher("root\\CIMV2","SELECT * FROM Win32_Processor");
 
foreach (ManagementObject queryObj in searcher.Get())

                {

string s =Convert.ToString(queryObj["LoadPercentage"]).Trim();

}
 
ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_OperatingSystem");
 
                foreach (ManagementObject queryObj in searcher.Get())

                {
 
Convert.ToString(queryObj["FreePhysicalMemory"]).Trim())

Convert.ToString(queryObj["FreeVirtualMemory"]).Trim())

Convert.ToString(queryObj["TotalVirtualMemorySize"]).Trim()));          

Convert.ToString(queryObj["TotalVisibleMemorySize"]).Trim())

}

Look up for Win32_operating system n other classes...
Processor load is in percentage.. ram you will have to calculate...

Performance counters is another way of doing this... though i think wmi queries from performance counters... (i may be wrong on this... )

did you add reference to System.Management?.... can you tell me wat exactly are you tryin? If you are tryin to get client info (client PC) by adding System.Management, code in .aspx... then the result that you get will be of the server PC... although you can remotely connect to client PC.. that require series of permission.. which are generally denied...still i think you can gather information ...by specifyin computer name in @"root\CIMV2\"
