Logwatch is a tool that will monitor your server's logs and email the administrator a digest on a daily basis.
* Ensure email is working. Instructions for doing so may be found in MailServer.
* Turn on universe repository. Instructions for doing so may be found in Repositories.
Update your package list with:
$ sudo apt-get update
Install Logwatch with:
$ sudo apt-get install logwatch
Create a directory the Logwatch package in the repositories currently does not create, but is required for proper operation:
$ sudo mkdir /var/cache/logwatch
Configuration shouldn't be edited in the install directory (/usr/share/logwatch). Copy logwatch.conf to /etc/logwatch before editing:
$ sudo cp /usr/share/logwatch/default.conf/logwatch.conf /etc/logwatch/conf/
Edit logwatch.conf to put in the e-mail where you want the report sent:
MailTo = email@example.com
Detail level of the logwatch report can be Low, Med or High. Default level is Low. To change that, edit the newly copied logwatch.conf:
Detail = High
For Ubuntu systems with apache server:
sudo cp /usr/share/logwatch/default.conf/logfiles/http.conf /etc/logwatch/conf/logfiles/
Then add *combined.log files to the list
