Since some weeks i manage my first Webserver, a Seaside application behind an Apache proxy on Linode, and i installed logwatch to send me daily logs.

Where can i get information on when i have to act as a consequence of what i read in these logwatch reports?

For example i read that all kinds of people try to login on funny nonexisting accounts or all kinds of webcrawlers test for nonexisting cms login pages, some ip adresses get banned and unbanned by fail2ban...

I assume that's normal? Is it? But how do i know that i probably have to do something? What do i look for in the logs?
