Write-EventLog

Applies To: Windows PowerShell 2.0

Writes an event to an event log.

Syntax

Write-EventLog [-LogName] <string> [-Source] <string> [-EventID] <int> [-Message] <string> [[-EntryType] {<Error> | <Warning> | <Information> | <SuccessAudit> | <FailureAudit>}] [-Category <Int16>] [-ComputerName <string>] [-RawData <Byte[]>] [<CommonParameters>]

Description

The Write-EventLog cmdlet writes an event to an event log.

To write an event to an event log, the event log must exist on the computer and the source must be registered for the event log.

The cmdlets that contain the EventLog noun (the EventLog cmdlets) work only on classic event logs. To get events from logs that use the Windows Event Log technology in Windows Vista and later versions of Windows, use Get-WinEvent.

Specifies a task category for the event. Enter an integer that is associated with the strings in the category message file for the event log.

-ComputerName <string>
