Usage examples

Systemd daemon notification

from systemd.daemon import notify, Notification

# Send READY=1
notify(Notification.READY)

# Send status
notify(Notification.STATUS, "I'm fine.")

# Send stopping
notify(Notification.STOPPING)

Write message into Systemd journal

from systemd import journal


journal.write("Hello Lennart")

# Or send structured data
journal.send(
    message="Hello Lennart",
    priority=journal.Priority.INFO,
    some_field='some value',
)

Or add logging handler to python logger

from systemd import journal
import logging
import uuid

logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger()
logger.addHandler(journal.JournaldLogHandler())

try:
    log.info("Trying to do something")
    raise Exception('foo')
except:
    logger.exception("Test Exception %s", 1)
