25.7.1 Configuring Logwatch

Logwatch is a monitoring system that you can configure to report on areas of interest in the system logs. After you install the logwatch package, the /etc/cron.daily/0logwatch script runs every night and sends an email report to root. You can set local configuration options in /etc/logwatch/conf/logwatch.conf that override the main configuration file /usr/share/logwatch/default.conf/logwatch.conf, including:

  • Log files to monitor, including log files that are stored for other hosts.

  • Names of services to monitor, or to be excluded from monitoring.

  • Level of detail to report.

  • User to be sent an emailed report.

You can also run logwatch directly from the command line.

For more information, see the logwatch(8) manual page.
