A parser for BSD syslog protocol (RFC 3164) messages

Project description


A parser for BSD syslog protocol (RFC 3164) messages

This library was extracted from syslog2IRC.


  • Python 3.7+


Install this package via pip:

$ pip install syslogmp


To parse a syslog message:

from syslogmp import parse

# Parse data (usually received via network).
message = parse(data)

# Let's see what we've got here.

Further Reading

For more information, see RFC 3164, “The BSD syslog Protocol”.

Please note that there is RFC 5424, “The Syslog Protocol”, which obsoletes RFC 3164. This package, however, only implements the latter.
