I just had a file server fail with symptoms that may be related to a
particular client pounding on it and may be related to a problem with the
file server itself.  If I had this statistic available, I could have seen
if the culprit appeared to be user programs trying to access directories
that they aren't permitted to access, or whether something else was
causing the problem.  It would have provided some clarity.

I agree that having this information per-connection is better than having
it per-server, but having *some* information about the frequency of this
problem would be nice.
