If you wish to receive logwatch’s report on a weekly basis instead of daily you have two perform two basic tasks.
First, edit /etc/logwatch/conf/logwatch.conf and change:
Range = yesterday
into:
Range = between -7 days and -1 days
Also, to enable the HTML output, change:
Format = text
into:
Format = html
Second, move the cron script from the daily directory to the weekly directoru with this command:
mv /etc/cron.daily/00logwatch /etc/cron.weekly/
Testing LogWatch and fixing missing files
Before quitting test the scripts because there are two common problems that usually occurs.
Run /etc/cron.weekly/00logwatch and check the output.
Problem 1: missing perl library
On some system you need to install the perl-DateManip library otherwise LogWatch will not understand the “Range” config directive.
If this happen on your system just install the perl library with the command:
apt-get install libdate-manip-perl
Problem 2: missing HTML templates
Since we enabled HTML output then LogWatch will look for an header and footer HTML template, if those files are not shipped with your distribution and if you get an error message about it then you have to manually create them.
Create the directory:
mkdir /usr/share/logwatch/default.conf/html/
After that you can create into this directory the two html templates.
As example you can use the following code for footer.html template:
</body></html>
And the following one for the header.html template:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
<head>
