One of the most important things a system administrator should do is to examine his system log files. However, most system administrators, myself included, have neither the time nor inclination to to do so. After setting up appropriate site filters (a bit of work), logalizer will automatically analyze log files and send the reports to you by email so that you can more easily detect attempted break-ins or problems with your systems.
This program is very easy to install. Customization to minimize the amount of noise is done by writing regular expressions to include and exclude parts of the log files that are interesting. Sample filter files are provided, but they will need to be tuned for your site.
