Some weeks ago someone asked me how to specify event ID, source and log name with the standard Send Event Log Message activity. Unfortunately the standard Send Event Log Message don’t provide a way to specific more than computer, message and severity. The event will always be generated with event ID 1 and source equals Orchestrator Runbook. The event is always written in the Application log.
To provide a way to specific more settings I created a new Create Event activity today. The activity is built around the EventCreate command. EventCreate enables an administrator to create a custom event in a specified event log, more info at Technet.
You can download the integration pack here. Note that this is provided “AS-IS” with no warranties at all. This is not a production ready management pack or solution, just an idea and an example.
