The page contains patterns examples of Windows Events Logs such as Application, Security and System.
Windows event log is a record of a computer's alerts and notifications. The Windows operating system classifies events by type. For example, an information event describes the successful completion of a task, such as installing an application.  A warning event notifies the administrator of a potential problem, such as low disk space.  An error message describes a significant problem that may result in a loss of functionality.  A success audit event indicates the completion of an audited security event, such as an end user successfully logging on.  A failure audit event describes an audited security event that did not complete successfully, such as an end user locking himself out by entering incorrect passwords.
