OpenLMI Journald usage
======================
The OpenLMI Journald provider depends on running journald daemon. See the `systemd
<http://www.freedesktop.org/software/systemd/man/systemd-journald.service.html>`_
manual for how to enable the journald service.
Listing a log
-------------
This example shows simple enumeration through available :ref:`LMI_JournalLogRecord<LMI-JournalLogRecord>`
instances in classic syslog-like format::
#!/usr/bin/lmishell
c = connect("localhost", "pegasus", "test")
for rec in c.root.cimv2.LMI_JournalMessageLog.first_instance().associators():
print "%s %s %s" % (rec.MessageTimestamp.datetime.ctime(), rec.HostName, rec.DataFormat)
.. note::
Only a limited number of records are being enumerated and printed out, please
see the :ref:`inst-enum-limit` remark.
Iterating through the log
-------------------------
This example uses iterator methods of the :ref:`LMI_JournalMessageLog<LMI-JournalMessageLog>`
class to continuously go through the whole journal::
#!/usr/bin/lmishell
c = connect("localhost", "pegasus", "test")
inst = c.root.cimv2.LMI_JournalMessageLog.first_instance()
r = inst.PositionToFirstRecord()
iter_id = r.rparams['IterationIdentifier']
while True:
x = inst.GetRecord(IterationIdentifier=iter_id, PositionToNext=True)
if x.rval != 0:
break
print "".join(map(chr, x.rparams['RecordData']))
iter_id = x.rparams['IterationIdentifier']
Sending new message to log
--------------------------
Simple example that uses :ref:`LMI_JournalLogRecord.create_instance()<LMI-JournalLogRecord>`
CIM method to send a new message in the log::
#!/usr/bin/lmishell
c = connect("localhost", "pegasus", "test")
c.root.cimv2.LMI_JournalLogRecord.create_instance({"CreationClassName": "LMI_JournalLogRecord",
"LogCreationClassName": "LMI_JournalMessageLog",
"LogName": "Journal",
"DataFormat": ""})
