imkmsg: /dev/kmsg Log Input Module
**********************************
=========================== ===========================================================================
**Module Name:** **imkmsg**
**Author:** `Rainer Gerhards <https://rainer.gerhards.net/>`_ <rgerhards@adiscon.com>
Milan Bartos <mbartos@redhat.com>
=========================== ===========================================================================
Purpose
=======
Reads messages from the /dev/kmsg structured kernel log and submits them
to the syslog engine.
The printk log buffer contains log records. These records are exported
by /dev/kmsg device as structured data in the following format:
"level,sequnum,timestamp;<message text>\\n"
There could be continuation lines starting with space that contains
key/value pairs.
Log messages are parsed as necessary into rsyslog msg\_t structure.
Continuation lines are parsed as json key/value pairs and added into
rsyslog's message json representation.
Configuration Parameters
========================
.. note::
Parameter names are case-insensitive.
This module has no configuration directives.
Caveats/Known Bugs:
===================
This module can't be used together with imklog module. When using one of
them, make sure the other one is not enabled.
This is Linux specific module and requires /dev/kmsg device with
structured kernel logs.
Examples
========
The following sample pulls messages from the /dev/kmsg log device. All
parameters are left by default, which is usually a good idea. Please
note that loading the plugin is sufficient to activate it. No directive
is needed to start pulling messages.
.. code-block:: none
$ModLoad imkmsg
