How to create Windows EventLog source from command line?

Try PowerShell 2.0's EventLog cmdlets

Throwing this in for PowerShell 2.0 and upwards:

• Run New-EventLog once to register the event source:

  New-EventLog -LogName Application -Source MyApp
  

• Then use Write-EventLog to write to the log:

  Write-EventLog 
      -LogName Application 
      -Source MyApp 
      -EntryType Error 
      -Message "Immunity to iocaine powder not detected, dying now" 
      -EventId 1
  

Try "eventcreate.exe"

An example:

eventcreate /ID 1 /L APPLICATION /T INFORMATION  /SO MYEVENTSOURCE /D "My first log"

This will create a new event source named MYEVENTSOURCE under APPLICATION event log as INFORMATION event type.

I think this utility is included only from XP onwards.
