Configuration
=============

This section is the **reference manual for configuring rsyslog**. It
covers all major configuration concepts, modules, and directives needed
to build robust logging infrastructures — from simple setups to complex
log processing pipelines.

rsyslog’s primary configuration file is located at:
``/etc/rsyslog.conf``

Additional configuration snippets are commonly placed in:
``/etc/rsyslog.d/*.conf``

Within these files, you define:
- **Input modules** (where logs come from)
- **Filters and parsers** (how logs are processed)
- **Actions** (where logs are sent)
- **Global directives** (overall behavior and performance tuning)

The topics listed below provide a complete guide to rsyslog
configuration.

Additional Resources
--------------------

- **Config snippets:** See `rsyslog config snippets
  <http://www.rsyslog.com/config-snippets/>`_ for ready-to-use building
  blocks.

- **Example configuration:** Download a sample configuration file:
  :download:`rsyslog-example.conf <rsyslog-example.conf>`.

Compatibility Note
------------------

rsyslog retains partial configuration compatibility with traditional
BSD-style syslogd, which can be helpful when migrating from older
implementations (e.g., on Solaris or AIX). On modern Linux systems,
native rsyslog configuration formats (especially RainerScript) are
recommended and provide access to all advanced features.
