• Homepage: https://github.com/jobec/rfc5424-logging-handler
• Documentation: http://rfc5424-logging-handler.readthedocs.org/

Features

• RFC 5424 Compliant.
• Python Logging adapter for easier sending of rfc5424 specific fields.
• No need for complicated formatting strings.
• TLS/SSL syslog support.
• Alternate transports like streams (ex. stderr, stdout, file, ...).

Installation

Python package:

pip install rfc5424-logging-handler

Usage

After installing you can use this package like this:

import logging
from rfc5424logging import Rfc5424SysLogHandler

logger = logging.getLogger('syslogtest')
logger.setLevel(logging.INFO)

sh = Rfc5424SysLogHandler(address=('10.0.0.1', 514))
logger.addHandler(sh)

logger.info('This is an interesting message', extra={'msgid': 'some_unique_msgid'})

This will send the following message to the syslog server:

<14>1 2020-01-01T05:10:20.841485+01:00 myserver syslogtest 5252 some_unique_msgid - \xef\xbb\xbfThis is an interesting message

Note the UTF8 Byte order mark (BOM) preceding the message. While required by RFC 5424 section 6.4 if the message is known to be UTF-8 encoded, there are still syslog receivers that cannot handle it. To bypass this limitation, when initializing the handler Class, set the msg_as_utf8 parameter to False like this:

sh = Rfc5424SysLogHandler(address=('10.0.0.1', 514), msg_as_utf8=False)
