Find out who manually triggered an Orchestration Group.

Hi folks, is there a way to find out who did triggered an Orchestration Group? 

I can find the start time in the console but there is no way to see which user did started it.

I am looking at two things:

• Somewhere that I can tell that it was triggered manually and if the option to skip the maintenance window was selected or not.
• The user name that manually launched it.

I notice in the log on the site server when it all started with the detection of the file in the Inbox and then a change in the database but nothing to prove my point.

The process is in place for some time and it never launched itself on it's own.

Thank you very much for the help. My management will be happy to know that it was launched manually.
