How does Serilog retrieve key information? - asp.net-core

Question

I need a requirement like this, I need to create a log message record of any kind using the logging framework. Then record some logs in some key places, and then I need to retrieve some information from it, how is this done?
enter image description here
Like this, or is there any other framework that is easier to implement? Any help is greatly appreciated.

Required Nuget Packages:
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>netcoreapp3.1</TargetFramework>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Serilog.AspNetCore" Version="4.1.0" />
<PackageReference Include="Serilog.Settings.Configuration" Version="3.3.0" />
<PackageReference Include="Serilog.Sinks.Console" Version="4.0.1" />
<PackageReference Include="Serilog.Sinks.File" Version="5.0.0" />
</ItemGroup>
<ItemGroup>
<Folder Include="MyLogInfo\" />
</ItemGroup>
</Project>
appsettings.json configuration：
{
"Serilog": {
"MinimumLevel": "Information",
"Override": {
"Microsoft.AspNetCore": "Warning"
},
"WriteTo": [
{
"Name": "Console "
},
{
"Name": "File",
"Args": {
"path": "MyLogInfo\\MyLogInfo.txt",
"formatter": "Serilog.Formatting.Json.JsonFormatter, Serilog"
}
}
]
}
}
Then add code in startup.cs to read these Serilog settings in the constructor：
public Startup(IConfiguration configuration)
{
Configuration = configuration;
Log.Logger = new LoggerConfiguration()
.ReadFrom.Configuration(configuration)
.CreateLogger();
}
Finally change the code in program.cs to specify that Host Builder uses Serilog from ASP.NET Core instead of the default logger：
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.UseSerilog()
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
});
}
