<P>The watchdog module monitors your website, captures system events in a log and records them to be reviewed by an authorized individual at a later time. The watchdog log is simply a list of events recorded during operation and contains usage data, performance data, errors, warnings and operational information. It is vital to check the watchdog report on a regular basis as it is often the only way to tell what is going on.</P>
<P>To ease administration, the watchdog will automatically remove old logs.</P>
