如何在Azure中为Net Core 2 App启用应用程序日志? [英] How to enable Application Logs in Azure for Net Core 2 App?
问题描述
我正在尝试以天蓝色启用应用程序日志. 我有一个虚拟的Net Core 2 App在天蓝色的appService中运行.
I am trying to enable application logs in azure. I have a dummy Net Core 2 App running in an appService in azure.
基本上,我的目标是在日志流和应用程序日志文件中查看跟踪消息,但是我没有找到正确的方法.
and basically my goal is to see the trace messages in the log stream and in the application log files but I have not found the right way to do this.
我在阅读其他文章时发现的挑战之一是,他们假设使用了适当的Web配置.
One of the challenge I have found reading other posts is that they assume a web config in place.
推荐答案
The documentation for ASP.NET Core 2.2 is here.
首先,启用应用程序日志记录"并选择适当的级别:
Firstly, enable Application Logging and choose the appropriate level:
这可能是诊断任何问题所需要做的.但是,如果要查看日志消息,请安装Microsoft.Extensions.Logging.AzureAppServices NuGet程序包.
This may be all you need to do to diagnose any problems. But if you want log messages and see them, install the Microsoft.Extensions.Logging.AzureAppServices NuGet package.
然后,配置日志记录:
using Microsoft.Extensions.Logging;
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.ConfigureLogging(logging =>
{
logging.AddAzureWebAppDiagnostics();
})
.UseStartup<Startup>();
现在您可以注入并使用ILogger:
Now you can inject and use ILogger:
public Startup(IConfiguration configuration, ILogger<Startup> logger)
{
Configuration = configuration;
this.logger = logger;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
logger.LogWarning("Starting up");
然后在Azure App Service中,单击日志流":
Then in the Azure App Service, click on Log stream:
