Easy Request Log in .Net Core

alialp profile image Ali Alp Updated on ・2 min read

After finishing up your Asp.Net Core project weather if it is a MVC or an API project, you may want to monitor all the requests which are being received by your endpoints. You can obviously log them in a file, however log files are unstructured and messy for instance to see which endpoint are being called the most or which user has requested which resources is pretty hard. With this in mind I have designed a Nuget library in order to provide a request logging functionality in just 2 lines of code called Easy-Request-Log.

Usage

Install it from Nuget.org
View the project source code on Github.com

dotnet add package easy-request-log

Add following to your Startup.cs class

public void ConfigeServices(IServiceCollection services)
{
    ...
    services.AddRequestLogger(maxLogCount:3);
    ...
}


public void Confige(IApplicationBuilder app, IWebHostEnvironment env)
{
    ...
    app.UseRequestLogger();
    ...
}

And that's it, the easy-request-log will make a sqlite database and add each incoming request to the database, the database has a limit of 10,000 records by default which you can change it in the ConfigureService method by passing the maxLogCount parameter, as it can be seen in the example above the maxLogCount has been set to 3 for the sake of the demo which means that the easy-request-log will keep only the last 3 records in the database on 4th request, the oldest request will be removed from the database.

Querying the logs


[ApiController]
[Route("[Controller]")]
public class LogController : ControllerBase
{
    private readonly IRequestLoggerService _requestLoggerService;

    public LogController(IRequestLoggerService requestLoggerService)
    {
        _requestLoggerService= requestLoggerService;
    }


    [HttpGet]
    public IEnumerable<HttpStatusCode> Get()
    {
        return _requestLoggerService.Find().ToList();
    }
}

by using the Dependency Injection you can access the RequestLoggerService which is being registered behind the scene with Scooped lifetime.
The result of hitting the http://your_ip/log will be like this:

[
  {
    "id": "88360c6e-cf8b-483d-95c3-5e4a3a397286",
    "datetime": "2020-03-08T17:03:09.513447",
    "username": null,
    "path": "/log",
    "queryString": "",
    "body": "",
    "statusCode": 200
  },
  {
    "id": "8bdbfe96-95f8-436a-a8ce-b03feea53481",
    "datetime": "2020-03-08T17:03:09.327419",
    "username": null,
    "path": "/log",
    "queryString": "",
    "body": "",
    "statusCode": 200
  },
  {
    "id": "cdb2f9ac-31e5-412a-ac33-501255ba5de3",
    "datetime": "2020-03-08T17:03:09.138145",
    "username": null,
    "path": "/log",
    "queryString": "",
    "body": "",
    "statusCode": 200
  }
]

“Take it easy” is nonsense , take it as hard as you can and don’t let it go :)

Hey, sounds like a cool package, could you add some tests to give some more insights into the workings of the app/making sure it works correctly, also if this is a project you need help on hit me up. :)

 

hey , I am glad that you liked it :) , I have applied some changes and also added a test , github.com/alicommit-malp/Easy-Req...
what do you think if you think is not enough i will be more than happy to work on it together .

 

This looks like a great starting point for simple logging. It’s a perfect candidate for the service provider model, so logs could be sent to other databases. Consider me interested!

 

Happy to hear that :)
