About
-----

`hat-syslog` provides server/client tooling based on Syslog logging protocol
as defined by `RFC 5425`_, `RFC 5426`_ and `RFC 6587`_.

This project includes implementations of:

* `Syslog Server`_

  Central concentrator for syslog messages with web interface for real
  time monitoring and filtering of log messages.

* `Syslog Handler`_

  Implementation of Python's standard library `logging.Handler` based on
  dedicated background logging thread.

* `Syslog Generator`_

  Simple testing tool responsible for generating syslog messages.

For more information see:

* `online documentation`_
* `git repository`_

        'version': 1,
        'formatters': {
            'default': {}},
        'handlers': {
            'syslog': {
                'class': 'hat.syslog.handler.SyslogHandler',
                'host': '127.0.0.1',
                'port': 6514,
