C#使用PerformanceCounter查詢CPU與記憶體使用狀況

最近有個需求是要監控多台windows電腦上的CPU和memory使用率。

PerformanceCounter example

using System;
using System.Diagnostics;
using System.Threading;
 
namespace test
{
    class Program
    {
        static PerformanceCounter cpu = new PerformanceCounter("Processor", "% Processor Time", "_Total");
        static PerformanceCounter memory = new PerformanceCounter("Memory", "% Committed Bytes in Use");
 
        static void Main(string[] args)
        {
            while (true)
            {
                Console.WriteLine("CPU: {0:n1}%", cpu.NextValue());
                Console.WriteLine("Memory: {0:n0}%", memory.NextValue());
                Thread.Sleep(1000);
            }
        }
    }
}
