What is Logwatch?

Logwatch is a log-monitoring system built into Red Hat Enterprise Linux. By default, it sends a daily email to the root user that contains potentially important entries from the system logs, such as kernel errors, user authentication failures, sudo commands, and disk utilization.

The output of the logwatch report is sent to the root user by default, but can easily be forwarded to any email address by adding an alias for the root user: How do I configure an email alias for my root account on Linux?
