Logwatch analyzes and reports on system logs. It is a customizable and pluggable log-monitoring system and will go through the logs for a given period of time and make a customizable report. It should work right out of the package on most systems.

Lots of incremental improvements and clean-ups and
bugfixes were made. Significant improvements were
made to the --range option (run --range help for
info). New services were added: audit, sonicwall,
and zz-network (which must be enabled in
logwatch.conf to make it active). The --numeric
option was added to inhibit certain DNS lookups.
Just about every filter has been improved.
Numerous filters have been added. HTML email
messages are now available. Multi-platform support
was improved, so Logwatch now works to some degree
on most Unix/Linux platforms.
