.NET CORE 获取LINUX硬件CPU使用率等状态信息

cat /proc/stat
​​vmstat,top,ps aux​​
三个命令都可以查看CPU内存或者进程等情况
然后看下面的代码
 
 
using System;
 using System.Diagnostics;
 using System.Runtime.InteropServices;
 namespace myApp
 {
     class Program
     {
         static void Main(string[] args)
         {
         Process[] p = Process.GetProcesses();//获取进程信息
             Int64 totalMem = 0;
             string info = "";
             foreach (Process pr in p)
             {
                 totalMem += pr.WorkingSet64 / 1024;
                 info += pr.ProcessName + "内存：-----------" + (pr.WorkingSet64 / 1024).ToString() + "KB\r\n";//得到进程内存
             }
             Console.WriteLine(info);
             Console.WriteLine("总内存totalmem:" + totalMem/1024+"M");
             Console.WriteLine("判断是否为Windows Linux OSX");
             Console.WriteLine($"Linux:{RuntimeInformation.IsOSPlatform(OSPlatform.Linux)}");
             Console.WriteLine($"OSX:{RuntimeInformation.IsOSPlatform(OSPlatform.OSX)}");
             Console.WriteLine($"Windows:{RuntimeInformation.IsOSPlatform(OSPlatform.Windows)}");
             Console.WriteLine($"系统架构：{RuntimeInformation.OSArchitecture}");
             Console.WriteLine($"系统名称：{RuntimeInformation.OSDescription}");
             Console.WriteLine($"进程架构：{RuntimeInformation.ProcessArchitecture}");
             Console.WriteLine($"是否64位操作系统：{Environment.Is64BitOperatingSystem}");
             Console.WriteLine("CPU CORE:"+Environment.ProcessorCount);
             Console.WriteLine("HostName:" + Environment.MachineName);
             Console.WriteLine("Version:" + Environment.OSVersion);
            Console.WriteLine("内存相关的:" + Environment.WorkingSet);
             string[] LogicalDrives = Environment.GetLogicalDrives();
             for (int i = 0; i < LogicalDrives.Length; i++)
             {
                 Console.WriteLine("驱动:" + LogicalDrives[i]);
             }
            // Console.ReadLine();
           
             //创建一个ProcessStartInfo对象 使用系统shell 指定命令和参数 设置标准输出
             var psi = new ProcessStartInfo("top", " -b -n 1") { RedirectStandardOutput = true };
             //启动
             var proc = Process.Start(psi);
             
          //   psi = new ProcessStartInfo("", "1") { RedirectStandardOutput = true };
             //启动
            // proc = Process.Start(psi);
            if (proc == null)
             {
                 Console.WriteLine("Can not exec.");
             }
             else
             {
                 Console.WriteLine("-------------Start read standard output-------cagy-------");
                 //开始读取
                 using (var sr = proc.StandardOutput)
                 {
                     while (!sr.EndOfStream)
                     {
                         Console.WriteLine(sr.ReadLine());
                     }
                    if (!proc.HasExited)
                     {
                         proc.Kill();
                     }
                 }
                 Console.WriteLine("---------------Read end-----------cagy-------");
                 Console.WriteLine($"Total execute time :{(proc.ExitTime - proc.StartTime).TotalMilliseconds} ms");
