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

如果您能在使用 .NET Core 为 AWS CloudWatch 设置 Serilog 接收器方面得到一些指导，我将不胜感激.我正在使用 appsettings.json 进行配置，但我无法将设置放入记录器中.尝试将日志信息写入 CloudWatch 时出现此错误:

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.
AmazonClientException: No RegionEndpoint or ServiceURL configured

Amazon.Runtime.ClientConfig.Validate() in ClientConfig.cs, line 446

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 凭证是使用环境变量设置的:

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

以防万一有人遇到同样的问题，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": "*"
}
