将 serilog 与 azure application insights 和 .Net core 结合使用

Question

Currently, I am using azure application insights directly for logging as given in this link Use latest version of Application Insight with .net core API and everything is working fine.

But I need to use the serilog for logging now with the help of azure application insight. Even I do some R&D about serilog ( https://github.com/serilog/serilog-sinks-applicationinsights ). But didn't get any idea. Could you please suggest me that how can we achieve that with the.Net core 3.0

Answer 1

Please follow the steps below:

First, in stall the following packages:

Microsoft.ApplicationInsights.AspNetCore, version 2.14.0

Serilog.AspNetCore, version 3.2.0

Serilog.Sinks.ApplicationInsights, version 3.1.0

Serilog.Settings.Configuration, version 3.1.0

In Program.cs:

public class Program
{     
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            })
           .UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
                    .ReadFrom.Configuration(hostingContext.Configuration)
                    .WriteTo.ApplicationInsights(new TelemetryConfiguration{ InstrumentationKey = "xxxxxxxxx" },TelemetryConverter.Traces)
             );                
}

In controller.cs :

Here is information how to setup app configuration for asp.net core, but it for v6.x

https://learn.microsoft.com/en-us/azure/azure-monitor/app/asp.net-core?tabs.netcorenew%2.netcore6

appsettings.json (example)

{
"Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*",
  "ApplicationInsights": {
    "ConnectionString": "Copy connection string from Application Insights Resource Overview"
  }
}
