What are Windows Event Logs?

Windows event logs are a compilation of a system’s notifications as well as alerts. As Microsoft rightly states an event as “any significant event in the program or in the system which requires users to get notified or an entry gets logged”.

Windows OS classifies the events on the basis of their type. Information event will describe successful task completion like application installation. Warning event will notify the admin of any problem like low disk space or high memory utilization. Error message will show critical issue which might lead to loss of functionality. Success audit event will show audited security event’s completion for example end user successfully logged on. Failure audit event indicated an audited security event which failed to complete successfully, for example an end user locked himself/herself by putting incorrect passwords.

Each and every event in log entry consists of the following information:

Computer: Name of the computer

Source: Component or program that triggered the event

Time: What time the event triggered/ time of occurrence.

Date: When the event occurred/ date of occurrence.

Type: Event type

Event type is further classified as –
