NewsStats (c) 2010-2013, 2025 Thomas Hochstein <thh@thh.name>

NewsStats is a software package for gathering statistical data live
from a Usenet feed and subsequent analysis.

This package is free software; you can redistribute it and/or modify

---------------------------------------------------------------------

What's that?

    There's a multitude of tools to create statistics about newsgroup
    usage: number of postings per month or per person, longest threads,
    and so on (see <https://th-h.de/net/usenet/stats/> [German language]
    for an incomplete list). Most of them use a per-newsgroup approach
    while NewsStats is hierarchy oriented.

    NewsStats will accumulate data from a live INN feed, allowing you
    to process the saved information later on.

Workflow

    NewsStats saves overview data and complete headers of (all)
    incoming postings to a (MySQL) database in real time.

    That raw data will be regularly - e.g. monthly - processed to a
    second set of database tables each dedicated to a certain
    statistical aspect, e.g. number of postings per group and month.

    Several kinds of reports can then be generated from those result
    tables.

Prerequisites

    NewsStats is written in Perl (5.8.x and above) and makes use of a
    MySQL database, so you will need Perl, some modules, mysql and, of
    course, INN.

    * Perl 5.8.x with standard modules
      - Cwd
      - Encode
      - File::Basename
      - Getopt::Long
      - Sys::Syslog

    * Perl modules from CPAN
      - Config::Auto
      - Date::Format
      - DBI

    * mysql 5.0.x

    * a working installation of INN

Installation instructions

    See INSTALL.

    Documentation is in /doc, configuration  in /etc, the NewsStats
    module in /lib and most scripts in /bin, while /contrib has some
    sample scripts that may have to be adjusted to work in your
    configuration.

Getting Started

    'feedlog.pl' will continuously feed raw data to your raw data
    table. See the feedlog.pl man page for more information.

    You can process that data via 'gatherstats.pl'; currently the
    tabulation of postings per group, injection server and posting
    agent (newsreader) per month is supported. See the gatherstats.pl
    man page for more information.

    Example:

        bin/gatherstats.pl

    will parse raw data from the last month and save the results in
    tables for postings per group, server and client, respectively.

    Report generation is handled by specialised scripts for each
    report type: 'groupstats.pl' for postings per group
    (s), 'hoststats.pl' for postings per injection server
    (s) and 'clientstats.pl' for postings per posting agent. See the
    groupstats.pl, hoststats.pl and clientstats.pl man pages for more
    information.

    Example:

        bin/groupstats.pl  -o postings-desc
        bin/hoststats.pl   -o postings-desc
        bin/clientstats.pl -o postings-desc -v

    will show reports for postings per group, per injection server and
    per client (with detailed client versions) for the last month,
    using the result tables filled by gatherstats.

    To post those reports to Usenet, change postingstats.pl according
    to your needs (sender, newsgroups and other headers, translation
    of table headers and text templates) and display a test posting
    by piping report data into postingstats.pl:

        bin/groupstats.pl --nocomments -s -f dump | bin/postingstats.pl

    If the result is to your liking, add a pipe to a inews
    implementation.

    Example:

        bin/groupstats.pl --nocomments -s -f dump | bin/postingstats.pl | contrib/tinews.pl -X

More information

    See the man pages for 'gatherstats' and the report generating
    scripts.
