Synopsis
========

:program:`traffic_logstats` [options]

Description
===========

:program:`traffic_logstats` is a log parsing utility, that is intended to
produce metrics for total and per origin requests. Currently, this utility
only supports parsing and processing the Squid binary log format, or a custom
format that is compatible with the initial log fields of the Squid format.

Output can either be a human readable text file, or a JSON format. Parsing can
be done incrementally, and :program:`traffic_logstats` supports restarting
where it left off previously (state is stored in an external file). This is
useful when collecting metrics periodically into a stats processing system,
and also supports the case where a log file is rotated.

The per-URL metrics (*-u*) requires that you specify a size of the LRU used
for keeping the counters. This is to assure that :program:`traffic_logstats`
does not consume an exorbitant amount of memory.
