I just committed to current (and soon to stable) some code to log
_failures_ in mbuf allocations, but that is only meant as an aid
to remove worse code in the drivers.
I'd be inclined to say that the XX% monitoring is better done by
userlevel daemons periodically polling the mbuf stats, rather than
doing some extra work every time you allocate or free an mbuf.
(Plus, just setting a threshold is not good, you also want
some histeresys, because you can easily conceive a system that
runs at XX % mbuf occupation, whatever XX you pick.)
