`systemd.journal` module
========================
.. automodule:: systemd.journal
:members: send, sendv, stream, stream_fd
:undoc-members:
`JournalHandler` class
----------------------
.. autoclass:: JournalHandler
Accessing the Journal
---------------------
.. autoclass:: _Reader
:undoc-members:
:inherited-members:
.. autoclass:: Reader
:undoc-members:
:inherited-members:
.. automethod:: __init__
.. autoclass:: Monotonic
.. autoattribute:: systemd.journal.DEFAULT_CONVERTERS
Example: polling for journal events
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This example shows that journal events can be waited for (using
e.g. `poll`). This makes it easy to integrate Reader in an external
event loop:
>>> import select
>>> from systemd import journal
>>> j = journal.Reader()
>>> j.seek_tail()
>>> p = select.poll()
>>> p.register(j, select.POLLIN)
>>> p.poll()
[(3, 1)]
>>> j.get_next()
Journal access types
~~~~~~~~~~~~~~~~~~~~
.. autoattribute:: systemd.journal.LOCAL_ONLY
.. autoattribute:: systemd.journal.RUNTIME_ONLY
.. autoattribute:: systemd.journal.SYSTEM_ONLY
Journal event types
~~~~~~~~~~~~~~~~~~~
.. autoattribute:: systemd.journal.NOP
.. autoattribute:: systemd.journal.APPEND
.. autoattribute:: systemd.journal.INVALIDATE
