How do you monitor storage (XCache or other) usage and performance?

How are the client software libraries made available to the users
To what extent, and how, can users customize their software stack (e.g. versions of Coffea and dependencies)?
To what extent do you provide support of the client software side? E.g. having one or few software distributions that are "guaranteed" to work?
