What tasks does a logging system solve and why is it necessary in an application?

The logging system in the application is designed to record information about the program's operation during its execution. It addresses several important tasks:

• Debugging and error diagnosis: logs help developers and testers understand what was happening in the system before an error occurred.
• Application monitoring: allows tracking the system's state, performance, and behavior in real-time.
• Audit and security: records important events, such as access attempts or data modifications.
• Analysis and improvement: logs can be used to identify bottlenecks and optimize the application's performance.

Without a logging system, it is difficult to understand the causes of failures and the application's behavior in production, especially if the error cannot be reproduced locally.
