Log analysis is the systematic process of examining and interpreting log files generated by computer systems, applications, or network devices. These logs record events, transactions, and other activities, providing a detailed account of system operations. By analyzing these logs, organizations can gain insights into system behavior, troubleshoot issues, identify security threats, and optimize performance.
