写在前面

 在 Microsoft.Extensions.Diagnostics.ResourceMonitoring 包提供了一系列定制 API，专用于监视 .NET 应用程序的资源利用率。

为了让控制台输出的样式更美观，可以安装一下Spectre.Console这个包

本例主要通过 IResourceMonitor 来获取资源状态信息，该接口支持检索与 CPU 和内存使用情况相关的数据，并且当前与 Windows 和 linux 平台兼容。

示例代码中用到的 Microsoft.Extensions.Logging 类库也需要通过NuGet安装一下。&nnfebrVbsp;

        var monitor = provider.GetRequiredService<IResourceMonitor>();
        _ = StartMonitoringAsync(monitor, new CancellationToken());

                }
            });
 
        Console.CancelKeyPress += (_, e) =>
        {
            e.Cancel = true;
        };
    }
 
}
