h1. Install Procedure for logwatch

h2. Requirements

To install logwatch you will need the following:

* a installed and supported operating system (e.g. CentOS 9.x)

* root-access

* a fast internet connection

h2. Preliminary Note

h2. Install 

Install @logwatch@:

<pre><code class="bash">

dnf install logwatch

</code></pre>

h2. 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

<pre><code class="bash">

vim /etc/logwatch/conf/logwatch.conf

</code></pre>

<pre>

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

Output = mail

</pre>

h3. reduce noise in output

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

<pre><code class="bash">

man 1 perlre

</code></pre>

<pre><code class="bash">

vim /etc/logwatch/conf/ignore.conf

</code></pre>

<pre>
