Elixir Request Logging

Introduction to Request Logging in Elixir

Request logging is an essential aspect of monitoring and debugging applications. In Elixir, the Plug library provides a convenient way to log requests using Plug.Logger. This tool helps developers trace API calls, monitor application performance, and ensure smooth functioning of services.

Setting Up Plug.Logger

To use Plug.Logger in your Elixir application, you need to add it to your project's dependencies and set it up within your plug pipeline. You can achieve this by editing your mix.exs file and adding :plug to your dependencies.

Integrating Plug.Logger into Your Application

After adding Plug to your dependencies, you can integrate Plug.Logger into your application by including it in your plug pipeline. This is typically done in your endpoint or router module.

Customizing Plug.Logger Output

Plug.Logger provides basic logging functionality out of the box, but you can customize the logging format and level according to your requirements. By default, it logs the HTTP method, request path, and response status. You can modify the logging metadata by configuring it in your application's configuration files.

Testing and Verifying Request Logs

Once integrated, it's crucial to test and verify that your request logging works as expected. You can do this by making API calls and checking the logs to ensure that all necessary information is being captured correctly. This step is essential for effective monitoring and debugging.
