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: >>> from systemd import journal >>> j = journal.Reader() >>> j.this_boot() >>> j.log_level(journal.LOG_INFO) >>> j.add_match(_SYSTEMD_UNIT="systemd-udevd.service") >>> for entry in j: # doctest: +SKIP ... print(entry['MESSAGE']) starting version ... See systemd.journal-fields(7) for more info on typical fields found in the journal. rNcstt|j|||tjdkrlt|_|dk rV|jjj||jjjt n+t j |_|dk r|jj |dS)aCreate an instance of Reader, which allows filtering and 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. rN)rr) superr>__init___sys version_info _ChainMap convertersmapsappendDEFAULT_CONVERTERScopyupdate)selfflagspathfilesrD) __class__r$r%r@s   zReader.__init__c CsC|jj|tj}y||SWntk r>|SYnXdS)a.Convert value using self.converters[key] If `key` is not present in self.converters, a standard unicode decoding will be attempted.

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: >>> import logging >>> log = logging.getLogger('custom_logger_name') >>> log.propagate = False >>> log.addHandler(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(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: >>> 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]). c smtt|j|x*|D]"}t|std|qWd|kr`tjd|d<||_dS)NzInvalid field name: ZSYSLOG_IDENTIFIERr)r?rr@r=rPrAargv_extra)rJrwrfname)rNr$r%r@s   zJournalHandler.__init__cCsy|j|}|j|j}t|dd}t|d|dt|d|jd|jd|jd|jd|j |j Wnt k r|j |YnXdS) aWrite record as journal event.
