Write-EventLog

  • Reference
Module:
Microsoft.PowerShell.Management

Writes an event to an event log.

Syntax

Write-EventLog
     [-LogName] <String>
     [-Source] <String>
     [[-EntryType] <EventLogEntryType>]
     [-Category <Int16>]
     [-EventId] <Int32>
     [-Message] <String>
     [-RawData <Byte[]>]
     [-ComputerName <String>]
     [<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 the Windows operating system, use the Get-WinEvent cmdlet.

Examples

Example 1: Write an event to the Application event log

PS C:\> Write-EventLog -LogName "Application" -Source "MyApp" -EventID 3001 -EntryType Information -Message "MyApp added a user-requested feature to the display." -Category 1 -RawData 10,20

This command writes an event from the MyApp source to the Application event log.

Example 2: Write an event to the Application event log of a remote computer

PS C:\> Write-EventLog -ComputerName "Server01" -LogName Application -Source "MyApp" -EventID 3001 -Message "MyApp added a user-requested feature to the display."

This command writes an event from the MyApp source to the Application event log on the Server01 remote computer.
