Powershell: create Windows event log

Create a NT eventlog for testing event monitor or rules:

Write-Eventlog -Logname ‘Application’ -Source ‘Hyperion EPMA DimensionServer’ -EventID 0 -EntryType Error -Message “This is a test of Gustavo Mendez (SCOM)”

 


 

More informationhttp://technet.microsoft.com/en-us/library/hh849847.aspx

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.
