Monitoring MySQL uptime and performance on a Debian server

Best resource I've found yet on how to monitor mysql (not a surprise)

But it doesn't have what Agaric needs, as far as automatic e-mail alerts.

Here's some of its advice, that I could understand well enough to translate into code.

(For root at localhost, the defaults)
# mysqladmin extended -p

# vmstat

MySQL error log - Nothing should written to the error log, after the server has completed its initialization sequence.

vi /var/log/mysql.err
