# Traditionally, we do counter logging via syslog.  (We could do it
# via HTTP post or something else instead, if we wanted.)  We can't
# rely on central syslogging being configured because that's a
# cluster-only package.  Fortunately, the syslog protocol is dead
# simple, so just fake a packet to the log host.
