ION Workflow WHERE IS THE LOG?

I have created a new ION Workflow.  I want it to send an email but I can only get it to send to Inbox within Tasks.  I am trying to find a log or something that will help me determine what the issue is but I can't find anything.  If I look at the Workflow "USEAGE", its shows nothing even though I have ran it more than a dozen times.  Can anyone please share how you can troubleshoot the ION Workflows?
