/dev/kmsg Log Input Module

Module Name: imkmsg

Authors: Rainer Gerhards <rgerhards@adiscon.com>
Milan Bartos <mbartos@redhat.com>

Description:

Reads messages from the /dev/kmsg structured kernel log and submits them to the syslog engine.

The printk log buffer constains 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 Directives:

This module has no configuration directives. Caveats/Known Bugs:

This is Linux specific module and requires /dev/kmsg device with structured kernel logs.

Sample:

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.
