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。 

代码实现

using Microsoft.Extensions.DependencyInjection;

using Microsoft.Extensions.Diagnostics.ResourceMonitoring;

using Microsoft.Extensions.Logging;

using Spectre.Console;

public class Program

{

public static void Main(string[] args)

{

var services = new ServiceCollection()

.AddLogging()

.AddResourceMonitoring();

var provider = services.BuildServiceProvider();

var monitor = provider.GetRequiredService();

_ = StartMonitoringAsync(monitor, new CancellationToken());

Console.ReadKey();

}

static async Task StartMonitoringAsync(IResourceMonitor monitor, CancellationToken cancellationToken)

{

var table = new Table()

.Centered()

.Title("Resource Monitoring", new Style(foreground: Color.Purple, decoration: Decoration.Bold))

.Caption("Updates every three seconds. *GTD: Guaranteed ", new Style(decoration: Decoration.Dim))

.RoundedBorder()

.BorderColor(Color.Cyan1)

.AddColumns(

[

new TableColumn("Time").Centered(),

new TableColumn("CPU %").Centered(),

new TableColumn("Memory %").Centered(),

new TableColumn("Memory (bytes)").Centered(),

new TableColumn("GTD / Max Memory (bytes)").Centered(),

new TableColumn("GTD / Max CPU (units)").Centered(),

]);

await AnsiConsole.Live(table)

.StartAsync(async ctx =>

{

var window = TimeSpan.FromSeconds(3);

while (cancellationToken.IsCancellationRequested is false)

{

var utilization = monitor.GetUtilization(window);

var resources = utilization.SystemResources;

table.AddRow(

[

$"{DateTime.Now:T}",

$"{utilization.CpuUsedPercentage:p}",

$"{utilization.MemoryUsedPercentage:p}",

$"{utilization.MemoryUsedInBytes:#,#}",

$"{resources.GuaranteedMemoryInBytes:#,#} / {resources.MaximumMemoryInBytes:#,#}",

$"{resources.GuaranteedCpuUnits} / {resources.MaximumCpuUnits}",

]);

ctx.Refresh();

await Task.Delay(window);

}

});

Console.CancelKeyPress += (_, e) =>

{

e.Cancel = true;

};

}

}

调用示例
