如何配置Serilog接收器以登录到CloudWatch [英] How to configure a Serilog sink for logging to CloudWatch

问题描述

我希望为使用.NET Core的AWS CloudWatch设置Serilog接收器提供一些指导。
我正在使用appsettings.json进行配置，但是无法将设置放入记录器中。尝试将日志信息写入CloudWatch时，会出现以下错误：

I would appreciate some guidance in setting up a Serilog sink for AWS CloudWatch with .NET Core. I'm using appsettings.json for configuration but I am unable to put the settings in the logger. When trying to write log information to CloudWatch this error appears:

An error occurred while starting the application.

我的代码如下：

在Startup.cs中：

In Startup.cs:

public Startup(IHostingEnvironment env)
{
    Configuration = new ConfigurationBuilder()
        .SetBasePath(env.ContentRootPath)
        .AddJsonFile("appsettings.json")
        .AddEnvironmentVariables()
        .Build();
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    Log.Logger = new LoggerConfiguration()
        .ReadFrom.Configuration(Configuration.GetSection("AWS.Logging"))
        .WriteTo.AWSSeriLog(Configuration)
        .CreateLogger();

    app.UseMvc();
}

我的appsettings.json：

My appsettings.json:

{
  "Logging": {
    "LogLevel": {
      "Default": "Warning"
    }
  },
  "AWS.Logging": {
    "Region": "eu-west-1",
    "LogGroup": "MyLogGroup",
    "LogLevel": {
      "Default": "Information",
      "System": "Information",
      "Microsoft": "Information"
    }
  },
  "AllowedHosts": "*"
}

我的开发人员机器上的AWS凭证通过使用环境变量设置：

Credentials for AWS from my developer machine are set by using environment variables:

AWS_ACCESS_KEY_ID=xxxxxxxxxx
AWS_DEFAULT_REGION=eu-west-1
AWS_SECRET_ACCESS_KEY=xxxxxxxxxxxxxxxxx

推荐答案

只要有人遇到相同的问题，这个appsettings.json解决了它：

Just in case anyone has the same problem, this appsettings.json solved it:

{
  "Logging": {
    "LogLevel": {
      "Default": "Warning"
    }
  },
  "Serilog": {
    "Using": [ "AWS.Logger.SeriLog" ]
    "Region": "eu-west-1",
    "LogGroup": "MyLogGroup",
    "LogLevel": {
      "Default": "Information",
      "System": "Information",
      "Microsoft": "Information"
    }
  },
  "AllowedHosts": "*"
}
