If you administer Linux systems, it’s a pretty good idea to keep an eye on the logs. A handy tool that parses your system’s logs and sends you an email report is well known logwatch. By default it sends daily log reports. But to me this is too often. I want weekly reports.
This is how I achieved this on Centos 5.
If they’re not already installed, install logwatch and perl-DateManip
sudo su - yum install logwatch perl-DateManip
Add a few options to logwatch.conf (I also like my output formatted in html)
echo "Range = between -7 days and -1 days" >> /etc/logwatch/conf/logwatch.conf echo "Output = html" >> /etc/logwatch/conf/logwatch.conf
By default logwatch installs itself in /etc/cron.daily, you should move it to /etc/cron.weekly
mv /etc/cron.daily/0logwatch /etc/cron.weekly
You can now run a test logwatch and check if it arrives:
