entries. Note that in order to access the system journal, a
non-root user must be in the `systemd-journal` group.
Example usage to print out all informational or higher level
messages for systemd-udevd for this boot:
>>> j = journal.Reader()
>>> j.this_boot()
>>> j.log_level(journal.LOG_INFO)
>>> j.add_match(_SYSTEMD_UNIT="systemd-udevd.service")
>>> for entry in j:
... print(entry['MESSAGE'])
See systemd.journal-fields(7) for more info on typical fields
found in the journal.

return of journal entries.
Argument `flags` sets open flags of the journal, which can be one
of, or ORed combination of constants: LOCAL_ONLY (default) opens
journal on local machine only; RUNTIME_ONLY opens only
volatile journal files; and SYSTEM_ONLY opens only
journal files of system services and the kernel.
Argument `path` is the directory of journal files. Note that
`flags` and `path` are exclusive.
Argument `converters` is a dictionary which updates the
DEFAULT_CONVERTERS to convert journal field values. Field
names are used as keys into this dictionary. The values must
be single argument functions, which take a `bytes` object and
return a converted value. When there's no entry for a field
name, then the default UTF-8 decoding will be attempted. If
the conversion fails with a ValueError, unconverted bytes
object will be returned. (Note that ValueEror is a superclass
of UnicodeDecodeError).
Reader implements the context manager protocol: the journal
will be closed when exiting the block.

>>> journal.send('Hello, again, world', FIELD2='Greetings!')
>>> journal.send('Binary message', BINARY=b'\xde\xad\xbe\xef')
Value of the MESSAGE argument will be used for the MESSAGE=
field. MESSAGE must be a string and will be sent as UTF-8 to
the journal.
MESSAGE_ID can be given to uniquely identify the type of
message. It must be a string or a uuid.UUID object.
CODE_LINE, CODE_FILE, and CODE_FUNC can be specified to
identify the caller. Unless at least on of the three is given,
values are extracted from the stack frame of the caller of
send(). CODE_FILE and CODE_FUNC must be strings, CODE_LINE
must be an integer.
Additional fields for the journal entry can only be specified
as keyword arguments. The payload can be either a string or
bytes. A string will be sent as UTF-8, and bytes will be sent
as-is to the journal.
Other useful fields include PRIORITY, SYSLOG_FACILITY,
SYSLOG_IDENTIFIER, SYSLOG_PID.

Log messages written to this file as simple newline sepearted
text strings are written to the journal.
The file will be line buffered, so messages are actually sent
after a newline character is written.
>>> stream = journal.stream('myapp')
>>> stream
<open file '<fdopen>', mode 'w' at 0x...>
>>> stream.write('message...\n')
will produce the following message in the journal::
PRIORITY=7
SYSLOG_IDENTIFIER=myapp
MESSAGE=message...
Using the interface with print might be more convinient:
>>> from __future__ import print_function
>>> print('message...', file=stream)
priority is the syslog priority, one of `LOG_EMERG`,
`LOG_ALERT`, `LOG_CRIT`, `LOG_ERR`, `LOG_WARNING`,
`LOG_NOTICE`, `LOG_INFO`, `LOG_DEBUG`.
level_prefix is a boolean. If true, kernel-style log priority
level prefixes (such as '<1>') are interpreted. See
sd-daemon(3) for more information.

Please see the Python logging module documentation for an
overview: http://docs.python.org/library/logging.html.
To create a custom logger whose messages go only to journal:
>>> log = logging.getLogger('custom_logger_name')
>>> log.propagate = False
>>> log.addHandler(journal.JournalHandler())
>>> log.warn("Some message: %s", detail)
Note that by default, message levels `INFO` and `DEBUG` are
ignored by the logging framework. To enable those log levels:
>>> log.setLevel(logging.DEBUG)
To redirect all logging messages to journal regardless of where
they come from, attach it to the root logger:
>>> logging.root.addHandler(journal.JournalHandler())
For more complex configurations when using `dictConfig` or
`fileConfig`, specify `systemd.journal.JournalHandler` as the
handler class. Only standard handler configuration options
are supported: `level`, `formatter`, `filters`.
To attach journal MESSAGE_ID, an extra field is supported:
>>> import uuid
>>> mid = uuid.UUID('0123456789ABCDEF0123456789ABCDEF')
>>> log.warn("Message with ID", extra={'MESSAGE_ID': mid})
Fields to be attached to all messages sent through this
handler can be specified as keyword arguments. This probably
makes sense only for SYSLOG_IDENTIFIER and similar fields
which are constant for the whole program:
>>> journal.JournalHandler(SYSLOG_IDENTIFIER='my-cool-app')
The following journal fields will be sent:
`MESSAGE`, `PRIORITY`, `THREAD_NAME`, `CODE_FILE`, `CODE_LINE`,
`CODE_FUNC`, `LOGGER` (name as supplied to getLogger call),
`MESSAGE_ID` (optional, see above), `SYSLOG_IDENTIFIER` (defaults
to sys.argv[0]).
