To keep an application or software running smoothly, it's crucial to regularly monitor and document system activities. Doing so helps identify and troubleshoot system issues and respond to security threats effectively. While most systems provide logs or records, they often lack sufficient detail for comprehensive analysis and troubleshooting.
This article covers the significance and advantages of logging, an essential checklist for logging best practices, the minimum data required for logs, and an overview of different types of logs, along with their formats.
Logging refers to the process of recording events, messages, and other information about the operation of a system or application over time. In software engineering, logging is a key component of application monitoring and debugging. It captures information about system events, user actions, error messages, and other data to diagnose issues and improve performance and reliability.
Logging helps identify and diagnose issues with systems, applications, or networks. By reviewing logs, system administrators can identify patterns or errors indicating an underlying problem.
