Log file analysis is both an essential and tedious part of


system administration. It is essential because it's the best way of profiling the usage of the service installed on the network. It's tedious because programs generate a lot of data and tools to report on this data are often unavailable or incomplete. When such tools exist, they are generally specific to one product, which means that you can't compare e.g. your Qmail and Exim mail servers.

Lire is a software package developed by the Stichting LogReport Foundation to generate useful reports from raw log files of various network programs. Multiple programs are supported for various types of network services. Lire also supports various output formats for the generated reports.
