TLDR: Logging is the practice of recording events, messages, and system activities to track application behavior and debug issues. Introduced in the 1970s with the rise of operating systems like UNIX, logging has become a cornerstone of software development and monitoring. It provides visibility into application performance, user actions, and system errors.

Effective logging categorizes messages into levels, such as DEBUG, INFO, WARN, ERROR, and FATAL. This categorization helps developers prioritize and analyze issues based on severity. For example, Log4j and Winston allow developers to customize log levels to fit application needs. Proper log formatting and context ensure clarity, enabling faster issue resolution.

Logging is essential for security and compliance, as it enables tracking access attempts, suspicious activities, and data changes. Centralized logging systems like the ELK Stack (Elasticsearch, Logstash, and Kibana) aggregate logs from multiple sources, providing real-time analysis and visualizations for detecting anomalies and maintaining compliance with regulations like GDPR or HIPAA.

To ensure effective logging, organizations must secure log data through encryption and access controls, implement retention policies to manage storage, and anonymize sensitive information. By integrating logging with SIEM tools, businesses can enhance monitoring, improve security, and proactively address operational challenges.

- Snippet from Wikipedia: Logging
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities.
Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions, though their efficiency for these purposes has been challenged.
Logging frequently has negative impacts. The harvesting procedure itself may be illegal, including the use of corrupt means to gain access to forests; extraction without permission or from a protected area; the cutting of protected species; or the extraction of timber in excess of agreed limits. It may involve the so-called "timber mafia". Excess logging can lead to irreparable harm to ecosystems, such as deforestation and biodiversity loss. Infrastructure for logging can also lead to other environmental degradation. These negative environmental impacts can lead to environmental conflict. Additionally, there is significant occupational injury risk involved in logging.
Logging can take many formats. Clearcutting (or "block cutting") is not necessarily considered a type of logging but a harvesting or silviculture method. Cutting trees with the highest value and leaving those with lower value, often diseased or malformed trees, is referred to as high grading. It is sometimes called selective logging, and confused with selection cutting, the practice of managing stands by harvesting a proportion of trees. Logging usually refers to above-ground forestry logging. Submerged forests exist on land that has been flooded by damming to create reservoirs. Harvesting trees from forests submerged by flooding or dam creation is called underwater logging, a form of timber recovery.
