Perhaps all this is a bit old stuff and this is only a really simple installation. But I was wondering if it could be worth to collect the three pieces of information you are asking for systematically when creating Jira Issues. There is a field Environment now where it must/could be described, but it is not a requirement of the system to field in this field to create an issue. I don't know if it is easy enough to make this change/addition and if it is worth the effort. Or course these are only a partial view of the whole system, but perhaps they could provide trends on using and problems. And it will make possible to answer your question! Just my 2c.
