LOGGING in ASP.NET Core | Getting Started With ASP.NET Core Series

Hello friends, Logging is an integral part of software development..NET Core supports logging API that works with a variety of built-in and third-party logging providers. Logging providers mostly store logs except for a few like Console, which displays logs.
In this video, we will learn more about the built-in logging providers, how they are configured, and how you can start using them for your applications. I will also show how to set up logging configuration, to control the logs that get written for different environments.

Hi Rahul, So far i have watched 7 to 8 videos in this playlist. It was really helpful to understand the concepts with examples. I would say it fare better than many paid courses out there for .Net Core in the market. Thanks for making videos like this. Can you also please below keep concepts in your video lists? 1. Custom Log provider 2. How to add Base path in api endpoint

[@TellaTrix]

it was really good insight over logging messages in console, As you have mentioned here "scope logging with transaction " i want to integrate with application insights to track the logging for each and every request. to know more with what was happened to particular call. Sometime my api controller call business logic and since it is asynchronous environment we were not able to track which particular request has the problem and we want to log with request id through out the lifecycle. After i watch this video i got clear insight what was happen with that call. Thanks for sharing this. really appreciate your efforts.

Hey Rahul ! Your video like 'Does one thing and does well' like 'S' of SOLID! great one! i wonder your voice tone remain same entire video length, You are like born teacher! is that possible to do Multi layer application, it don't have to be in detail but project structure (DAL, BLL, Web) with Dependency injection along with Test project, just skeleton will do! Thank you.

[@RahulNath]

Thanks Jay and happy that you are finding these useful. Yes I am doing a video on setting up project structure soon, probably in September.

[@Blr046]

Really liked the video. Thank you so much. I am using nlog for logging, will explore on Seq. Is it possible to turn ON or OFF either nlog or Seq based on the need without changing the implementation.

[@RahulNath]

Thank you! Yes you can switch case it in the registration. I usually have a #IF Debug and set up Seq on my local even if it's not used in production, so that at least locally I can look at logs. Is that what you had in mind?

[@ashwitapola2229]

Very Informative. Is Seq is similar to Application Insights?

[@RahulNath]

Thank you Ashwita 😀 Seq is for centralised logging whereas app insights is more for application level monitoring. Let know if that helps.

Hi Rahul, Thank you very much for all the information. The builder.AddConsole(); not working and to reinitiate the logger after clearprovider() function I had to use the builder.debug(); What is the reason for this issue. Thank you

Glad you like the video Janith. I just tried ClearProviders and added AddConsole and works fine for me. Can you elaborate what is not working or put a sample code repo so that I can look.

Are you using any specific Logging library? I would try and inject in the logger context if possible. Here is a example when using Serilog as the library stackoverflow.com/questions/51261177/add-username-into-serilog Also make sure you are not having any PII info being logged.
