Definition
Monitoring and Logging refers to the systematic collection, analysis, and storage of data about system performance, security events, and user activity. It involves setting up tools to observe system behavior in real time and recording detailed event logs for later review. This practice is crucial for maintaining operational health, identifying security threats, and troubleshooting issues effectively. For instance, a web server might log every incoming request, including the IP address, timestamp, and requested resource, allowing administrators to track traffic patterns and detect suspicious activity. Unlike simple performance metrics, logging captures granular details of individual events, providing a historical record for audits and investigations. Understanding Monitoring and Logging is essential for domains like Security+, Network+, CySA+, and AWS Certified Solutions Architect Associate.
