Install Procedure for logwatch¶

Requirements¶

• a installed and supported operating system (e.g. CentOS 9.x)
• root-access
• a fast internet connection

Preliminary Note¶

Install¶

Install logwatch:

dnf install logwatch

Configure¶

the default output is to stdout
the cron.daily call is using the option --output mail

if you still want to override default output from stdout to mail then

vim /etc/logwatch/conf/logwatch.conf

# Local configuration options go here (defaults are in /usr/share/logwatch/default.conf/logwatch.conf)
Output = mail

reduce noise in output¶

Just for the records: logwatch uses Perl style regexes in ignore.conf . So look at

man 1 perlre

vim /etc/logwatch/conf/ignore.conf
