Write-EventLog
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 10,20This 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.
