<p>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.
</p>
<p>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.
