Event logging is the process of recording events that occur within a computer system or network. This can include actions like user logins, system errors, and application usage. The logs serve as a historical record, helping administrators monitor system performance and troubleshoot issues. These logs are typically stored in files or databases and can be analyzed to identify patterns or anomalies. Tools like Syslog or Windows Event Viewer are commonly used for managing and reviewing these logs. Effective event logging is crucial for maintaining security and ensuring compliance with regulations.
