Hi Henry, I have just checked the back pressure relevant codes. It is indeed not included in metric system. As a workaround way, you can manually trigger the back pressure tracking through RESTful API (see details in [1]) periodically. And plot with the data returned.
BTW I think it's a reasonable requirement. Maybe you could start a discussion in dev mailing list.
