The monitor backend doesn't follow any specification, that's why it may
change across versions; it has been marked (or at least intended) as
experimental for a long while, and the version currently in HEAD should
remain stable for a while (only minor differences with 2.2).  As I
mentioned in early postings about it, the monitor backend is mainly
intended to be useful; as such, feel free to suggest desired features, or
slight reworking of the presented data.  I expect it to grow according to
users (especially administrators) feedback, although i received very
little over the years.
