Easy way to see know that a Teardown automation event ran properly

If I have an event that is supposed to run at Teardown, the VM has of course disappeared. So how do I know if the Teardown event actually ran (properly)? Is there some kind of event log in the GUI that indicates this?

Can see teardown task executions in /operations/activity/history

Thanks. I added a workflow to send an email when a VM has been deleted.
