使用Serilog(或任何结构化日志库)的Steeltoe动态日志记录配置

问题描述 投票:0回答:1

这可能是How to set Steeltoe Dynamic Logging works with 3rd party loggers as Serilog?的重演。我想利用Steeltoe动态日志记录配置(将帮助我动态调整日志级别而无需重新部署),并希望使我的日志语句更加结构化。所以我决定看看Serilog。这是我的代码

public class Program
    {

        /// <summary>
        /// Application entry point.
        /// </summary>
        /// <param name="args">arguments.</param>
        public static void Main(string[] args)
        {
            BuildWebHost(args).Run();
        }

        /// <summary>
        /// 
        /// </summary>
        /// <param name="args"></param>
        /// <returns></returns>
        public static IWebHost BuildWebHost(string[] args) =>
                    WebHost.CreateDefaultBuilder(args)
                        .UseStartup<Startup>()
            .ConfigureAppConfiguration((hostContext, config) =>
            {
                config.AddCloudFoundry();
            })
            .ConfigureLogging((context, builder) =>
            {
                // We need to clear providers which are added by CreateDefaultBuilder(). 
                // Please refer https://github.com/aspnet/Logging/issues/648. Otherwise log entries will be duplicated 
                // since AddDynamicConsole again add console logger
                builder.ClearProviders();
                if (context.HostingEnvironment.IsDevelopment())
                {
                    builder.AddDebug();
                }
                builder.AddDynamicConsole();
            })
            .UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
                 .ReadFrom.Configuration(hostingContext.Configuration)
                 .Enrich.FromLogContext()
                 .WriteTo.Console(outputTemplate:
                 "[{Level:u3}] [{Properties}] {Message}{NewLine}{Exception}")
            .WriteTo.Trace())
            .Build();
    } 

但这不符合预期。在PCF应用程序管理器中,除了“默认”之外,我无法看到任何日志记录提供程序。如果我取消注释

UseSerilog()

他们也回来了。顺便说一下,我不想把自己限制在Serilog,这可能与NLog(听说它也支持结构化日志记录)有关吗?或者,欢迎任何其他结合结构化日志记录和动态日志记录配置的想法

Steeltoe现在通过Steeltoe.Extensions.Logging.SerilogDynamicLoggerdev branch MyGet feed初步支持Serilog。源代码和单元测试在this repository,我们欢迎您的反馈!

使用新的NuGet包,您应该能够做到这一点

new WebHostBuilder()
  .ConfigureLogging((builderContext, loggingBuilder) =>
  {
    loggingBuilder.AddConfiguration(builderContext.Configuration.GetSection("Logging"));

    // Add Steeltoe Dynamic Serilog provider
    loggingBuilder.AddSerilogDynamicConsole();
  })

然后就像使用预先存在的动态记录器一样。
