一 简介

无论是微服务还是其他任何分布式系统，都需要一个统一处理日志的系统，这个系统

必须有收集，索引，分析查询的功能。asp

.net core自己的日志是同步方式的，正如文档所言：

所以必须自己提供一个日志提供程序，那正如文档所言，还有什么比kafka更合适的呢。

从kafka往后那就是elasticsearch      kibana，那是自然而然的事情。

二 asp.net core 日志详解

概念：

类别：类别是以使用的用途进行分类的，比如var log= LoggerFac.CreateLogger<Startup>();这一句，

以StartUp类的全名作为一个分类，还有一些内置的system，Microsoft，主要是为了更细粒度控制日志。

如果StartUp类出现了问题，打印日志就可以控制在StartUp这一类别下，为这个类别设置debug，

仅仅打印这个类别这个级别的日志信息，使用filter功能可以很容易控制。

日志级别：Trace，debug，info，warning，error等

Trace：因为可以看到组件内部运行状况，而且会有很大安全隐患，所以不建议在生产开启这个功能，

比如mysql lib库的trace可以打印出数据库连接字符串的。

日志提供程序：日志提供程序可以看作日志信息的的io重定向。

控制台：这个不用说了。

调试：就是debug，在 Linux 中，此提供程序将日志写入 /var/log/message。

在windows中就是经典的System.Diagnostics.Debug功能，这是.net提供的调试功能，

非常详细，在开发中非常有用，而且通过配置可以自定义存储，比如一个log文件。

下面是vs中最常见的。

EventSource 提供程序在windows下可用，在linux下没可用但是没有相关事件，所以和没用一样。

Windows EventLog 提供程序和TraceSource 提供程序都是在windows环境下是使用。

三 开发

添加各种事件提供程序：因为是windows下所以EventSource事件是可以用的。

  1.  var host = new WebHostBuilder().ConfigureAppConfiguration((webHostBuild,configBuild) =>
  2.             {
  3.                 var env = webHostBuild.HostingEnvironment;
  4.  
  5.                 configBuild.AddJsonFile("appsettings.json")
  6.                 .AddJsonFile($"appsettings.{env.EnvironmentName}.json"
  7.                 ,optional:true,reloadOnChange:true)
  8.                 .SetBasePath(Directory.GetCurrentDirectory());
  9.             }).ConfigureLogging((hostingContext, logging) => {
  10.                 logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging"))
  11.                 .AddConsole()
  12.                 .AddDebug()
  13.                 .AddEventSourceLogger();
  14.             }).UseKestrel()
  15.             .UseStartup<Startup>();
  16.              host.Start();
  17.             Console.ReadKey();
  1. {
  2.   "Logging": {
  3.     "LogLevel": {
  4.       "Default": "Debug",
  5.       "System": "Information",
  6.       "Microsoft": "Information"
  7.     }
  8.   }
  9. }

日志配置：默认日志debug,system分类info级别，Microsoft分类是info级别。

这个LogLevel下的节点就是日志筛选功能。

  1. {
  2.   "Logging": {
  3.     "LogLevel": {
  4.       "Default": "Debug",
  5.       "System": "Information",
  6.       "Microsoft": "Information"
  7.     }
  8.   }
  9. }

总结：asp.net core中集成了很多以前.net的日志和调试功能，有点混乱，linux目前能用的提供程序有console和debug，EventSource和事件查看器还有Trace只能在windows专用。上面日志有一些区别，所以加debug提供程序，在相同分类和都具有console提供程序下debug会多出一些信息，所以并不是每个提供程序都共享所有日志信息，根据提供程序不同，会有多余的一些日志信息被加进来。但是如上图所示，并不影响，因为仅仅是一些系统级别的debug提供程序会多出一些信息，mvc模块给出的信息完全一致。
