Designing Consideration for a Logging System

A basic logging system should include the following functionalities to implement a logging system:

• Logging Levels: Use various log levels to group communications according to their significance or seriousness. The log levels DEBUG, INFO, WARNING, ERROR, and CRITICAL are often seen.
• Final Destinations: Permit users to choose the destination of log messages with flexibility. Log files, console output, and external services are examples of this.
• Context and Timestamps: To give log entries a chronological context, provide timestamps. You can just choose to provide additional context by including file names, line numbers, or function names.
• Setup: Give developers the ability to dynamically customize the logging system so they may change the destinations or reporting levels without having to change the code.

The logging system is a very critical component to track how the application behaves, find the problems, and understand the performance of the system. We can create a simple also very effective logging system in C++ to capture and record various events and data that occur during the execution of a program.
