Python3: Journal Logging Does Not Show Log Level?

This is the python I am using. $ python3 --version Python 3.5.2 This is the test code after some googling (How to log to journald (systemd) via Python?). I am trying to use journa

Solution 1:

Your basicConfig statement will create a StreamHandler, the format you set here will only be for the log you get on stdout. Look at the docs for Formatter objects which says If no fmt is specified, '%(message)s' is used.. Therefore you have to create a separate Formatter and use setFormatter on the JournalHandler to get your desired output.

A basic modification of your code below:

#!/usr/bin/env python

import logging
from systemd.journal import JournalHandler

log = logging.getLogger('test')
log_fmt = logging.Formatter("%(levelname)s %(message)s")
log_ch = JournalHandler()
log_ch.setFormatter(log_fmt)
log.addHandler(log_ch)
log.setLevel(logging.DEBUG)
log.warning("warn")
log.info("info")
log.error("error")
log.debug("debug")

This gives your desired output in the log
