logging-journald

Pure python logging handler for writing logs to the journald using native protocol.

import logging
from logging_journald import JournaldLogHandler, check_journal_stream

# Use python default handler
LOG_HANDLERS = None


if (
    # Check if program running as systemd service
    check_journal_stream() or
    # Check if journald socket is available
    JournaldLogHandler.SOCKET_PATH.exists()
):
    LOG_HANDLERS = [JournaldLogHandler()]

logging.basicConfig(level=logging.INFO, handlers=LOG_HANDLERS)
logging.info("Hello logging world.")

MESSAGE_ID field

As defined in catalog documentation:

A 128-bit message identifier ID for recognizing certain message types, if this is desirable. This should contain a 128-bit ID formatted as a lower-case hexadecimal string, without any separating dashes or suchlike. This is recommended to be a UUID-compatible ID, but this is not enforced, and formatted differently. Developers can generate a new ID for this purpose with systemd-id128 new.

So you're free to choose how you want to act. By default, MESSAGE_ID is generated as a hash of the message and some static fields. But you can disable this by passing use_message_id=False to the class constructor.

from logging_journald import JournaldLogHandler

...

handler = JournaldLogHandler(use_message_id=False)
