如何配置环境以防止记录 Microsoft 消息？

Question

我有一个 Microsoft DotNet Core 2.0 应用程序运行作为 AWS ECS 服务，它位于负载均衡器后面，它的 Cloudwatch 日志中充满了来自 AspNetCore.Hosting 层的消息，因为负载均衡器的运行状况检查调用应用程序的状态端点：

17:49:18 [40m[32minfo[39m[22m[49m: Microsoft.AspNetCore.Hosting.Internal.WebHost[1]
17:49:18 Request starting HTTP/1.1 GET http://10.10.1.184/status
17:49:18 [40m[32minfo[39m[22m[49m: Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker[1]
17:49:18 Executing action method Controller.Controllers.StatusController.Status (MyEcsApplication) with arguments ((null)) - ModelState is Valid

17:49:18 Executing JsonResult, writing value Controller.Models.StatusModel.
17:49:18 [40m[32minfo[39m[22m[49m: Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker[2]
17:49:18 Executed action Controller.Controllers.StatusController.Status (MyEcsApplication) in 4.8748ms
17:49:18 [40m[32minfo[39m[22m[49m: Microsoft.AspNetCore.Hosting.Internal.WebHost[2]
17:49:18 Request finished in 32.7132ms 200 application/json; charset=utf-8

应用程序的日志级别设置为调试，因为我正在进行初始测试，这些消息使日志非常嘈杂。有没有办法配置日志记录以排除来自 Microsoft.AspNetCore 的消息？

这是我的 appsettings.json 文件：

{
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Debug"
    }
  },
  "AWS": {
    "Profile": "default",
    "Region": "us-east-1"
  },
  "Log4Net": {
    "ConfigFileRelativePath": "log4net.xml",
    "Repository": "NETCoreRepository"
  },
  "Swagger": {
    "FileName": "MyEcsApplication.xml"
  }
}

和 Program.cs 启动代码：（编辑以添加 ConfigureAppConfiguration）

var host = new WebHostBuilder()
            .UseKestrel()  // use default web server on port 80
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseStartup<Startup>()
            .ConfigureAppConfiguration((hostingContext, config) =>
            {
                var env = hostingContext.HostingEnvironment;
                config.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
                      .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true, reloadOnChange: true);
                config.AddEnvironmentVariables();
            })
            .ConfigureLogging((hostingContext, logging) =>
             {
                 logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
                 logging.AddConsole();
                 logging.AddDebug();
             })
            .Build();

// run the web host and block until host shutdown
host.Run();

尝试将您的 Logging LogLevel 更改为如下内容：

"Logging": {
  "LogLevel": {
    "Microsoft": "Error",
    "Default": "Debug"
  }
}

这里有一些关于过滤的文档：https://docs.microsoft.com/en-us/aspnet/core/fundamentals/logging/?tabs=aspnetcore2x#log-filtering
