How can I get CPU Utilization for my all servers?

ASP.NET

C#3.5

My application is hosted on 5-6 servers, I need to develop a window service which will run on my machine and will give me a alert if CPU utilization gets more than some set limit for more than 30 min.

I got a sample code through which I can get the result but for this I need to host this service on each machine which I dont want.

public int getCPUCounter()
   {

       PerformanceCounter cpuCounter = new PerformanceCounter();
       cpuCounter.CategoryName = "Processor";
       cpuCounter.CounterName = "% Processor Time";
       cpuCounter.InstanceName = "_Total";

       // will always start at 0
       dynamic firstValue = cpuCounter.NextValue();
       System.Threading.Thread.Sleep(1000);
       // now matches task manager reading
       dynamic secondValue = cpuCounter.NextValue();

       return secondValue;

   }

Thanks in advance
