Multi environment logging with Serilog for AspNet Core Few months ago we saw how to get started with Serilog. We discovered what was Serilog and the different concepts of settings, enrichers and sinks. Today we will see how we can take Serilog further and configure a logging mechanism for an application running in multi environment. Setup Serilog Multi environment AWS CloudWatch 1. Setup Serilog If you have never seen Serilog before you can start with my previous post on How to get started with Serilog . In order to configure our first logging mechanism, we start by creating an AspNet Core application and install Serilog , Serilog.AspNetCore and the sinks we will be using Serilog.Sinks.Console , Serilog.Sinks.File . RollingFile sink also exists but it has been superseded with File sink. Next we can configure the logger to write to Console and write to a file: public static IWebHost BuildWebHost(string[] args) { return WebHost.CreateDefaultBuilder(args) ...

Logging in ASP NET Core with Serilog At each stages of an application development cycle, good logs are necessary to debug and fix bugs efficiently. Serilog is a logging framework allowing developers to log structured logs into different ouput platforms. Today we will see how we can set it up in three parts Serilog for ASP.NET Core Console sink Rolling File sink Environment enricher All the code discussed here can be found on my GitHub https://github.com/Kimserey/SerilogTest . 1.

They are built by assembling pieces of information, elapsed time or process name, into a string message. Once constructed into a message, they are written into an ouput stream, console or file for example. The message contains the timestamp the log message.
