In short, No. There's no really easy way to tell. I've talked with a couple people and found that those actions are not really captured anywhere, except maybe the apache logs. Since the action generates a URL that ends in .pdf -- Clicking on View As PDF here, https://community.jivesoftware.com/thread/255375.pdf -- You could give that a try, but the solution doesn't sound that simple.
Hope this helps some.
