OneLog

OneLog is a logging library for ASP.NET Core applications, that writes structured events into file in JSON format. All events are written within an HTTP request will be written into file as one JSON object.

Getting started

OneLog is installed from NuGet.

Install-Package OneLog

Firstly, you need to set up configuration in your appsettings file.

"OneLog": 
{
     "LoggerFolder": "C:\\Users\\Shevchenko\\source\\repos\\OneLog\\Logs\\",
     "FileName": "Requests",
     "IsBuffered": "true" 
}

Description of configuration:

• LoggerFolder - folder, where files will be created
• FileName - name for log file
• IsBuffered - If IsBuffered is false, logs will be written to file at once, but it will slow down your application a little bit

Secondly, you add to ConfigureServices method:

public void ConfigureServices(IServiceCollection services)
{
     services.AddOneLog(Configuration);
}

Then, you add to Configure method:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
     app.UseOneLog();
}

That is it for configuration and it is ready to use.

Usage

ILogger is injected into your controllers, services...

logger.LogEvent("REQEUST", "START", EventCategory.Information);
