What is the purpose of the ERROR logging level?

The purpose of the ERROR logging level is to indicate a potential problem that affects user experience. This logging level is essential for developers and system administrators as it highlights issues that may hinder the application's functionality or degrade user experience. When an error is logged, it often contains critical information about what went wrong, allowing developers to diagnose and address issues effectively.

In contrast, other logging levels serve different purposes. For instance, logging successful transactions or normal operations does not inform about potential issues; instead, those logs capture routine activities that do not necessitate immediate attention. Therefore, focusing on the ERROR logging level is crucial for maintaining the application's reliability and ensuring a positive user experience by addressing problems promptly.
