Description: A log entry is a single record within a log file that contains details about a specific event. These entries are fundamental for data management and analysis in computer systems, as they allow administrators and developers to track and understand the behavior of applications and systems. Each log entry typically includes information such as the date and time of the event, the severity level (e.g., info, warning, error), the source of the event (such as the name of the application or system component), and a descriptive message that provides context about what occurred. Log entries are essential for debugging, auditing, and performance monitoring, as they offer a detailed view of the internal operations of a system. Additionally, in the context of observability, log entries integrate with metrics and traces to provide a complete picture of a system’s state, facilitating problem identification and performance optimization.
