You actually need both: Send an error message and keep a log that can be
checked easily. The error message is good enough most of the time, but
there are plenty of users so clueless that they will be unable to find or
may even have deleted the error. In such cases tech support has the
choice between telling them to wait for the problem to come up again or
check the logs.
