-<h1>Kernel Log Input Module</h1>
-<p><b>Module Name:&nbsp;&nbsp;&nbsp; imklog</b></p>
-<p><b>Author: </b>Rainer Gerhards
-&lt;rgerhards@adiscon.com&gt;</p>
-<p><b>Description</b>:</p>
-<p>Reads messages from the kernel log and submits them to the
-syslog engine.</p>
-<p><b>Configuration Directives</b>:</p>
-<ul>
-<li><strong>LogPath</strong><br>
-The path to the Kernel log. This value should only be changed if you really know what
-you are doing.</li>
-<li><strong>InternalMsgFacility
-&lt;facility&gt;</strong><br>
-The facility which messages internally generated by imklog will have.
-imklog generates some messages of itself (e.g. on problems, startup and
-shutdown) and these do not stem from the kernel. Historically, under
-Linux, these too have "kern" facility. Thus, on Linux platforms the
-default is "kern" while on others it is "syslogd". You usually do not
-need to specify this configuratin directive - it is included primarily
-for few limited cases where it is needed for good reason. Bottom line:
-if you don't have a good idea why you should use this setting, do not
-touch it.</li>
-<li><b>PermitNonKernelFacility [on/<i>off</i>]</b><br>
-At least under BSD the kernel log may contain entries
-with non-kernel facilities. This setting controls how those are
-handled. The default is "off", in which case these messages are
-ignored. Switch it to on to submit non-kernel messages to rsyslog
-processing.</li>
-<li><b>ParseKernelTimeStamp</b> [on/<b>off</b>]<br>
-If enabled and the kernel creates a timestamp for its log messages, this timestamp will be
-parsed and converted into regular message time instead to use the receive time of the kernel
-message (as in 5.8.x and before). Default is to not parse the kernel timestamp, because the
-clock used by the kernel to create the timestamps is not supposed to be as accurate as the
-monotonic clock required to convert it. Depending on the hardware and kernel, it can result
-in message time differences between kernel and system messages which occurred at same time.
-<li><b>KeepKernelTimeStamp</b> [on/<b>off</b>]<br>
-If enabled, this option causes to keep the [timestamp] provided by the kernel at the begin
-of in each message rather than to remove it, when it could be parsed and converted into
-local time for use as regular message time. Only used when <b>ParseKernelTimestamp</b> is on.
-<li><b>ConsoleLogLevel</b> [<i>number</i>]
-(former klogd -c option) -- sets the console log level. If specified, only messages with
-up to the specified level are printed to the console. The default is -1, which means that
-the current settings are not modified. To get this behavior, do not specify
-ConsoleLogLevel in the configuration file. Note that this is a global parameter. Each time
-it is changed, the previous definition is re-set. The one activate will be that one that is
-active when imklog actually starts processing. In short words: do not specify this
-directive more than once!
-</ul>
-<b>Caveats/Known Bugs:</b>
-<p>This is obviously platform specific and requires platform
-drivers.
-Currently, imklog functionality is available on Linux and BSD.</p>
-<p>This module is <b>not supported on Solaris</b> and not needed there.
-For Solaris kernel input, use <a href="imsolaris.html">imsolaris</a>.</p>
-<p><b>Sample:</b></p>
-<p>The following sample pulls messages from the kernel log. 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 kernel messages.<br>

-<p><b>Legacy Configuration Directives</b>:</p>
-<ul>
-<li><strong>$KLogInternalMsgFacility
-&lt;facility&gt;</strong><br>
-equivalent to: InternalMsgFacility</li>
-<li><span style="font-weight: bold;">$KLogPermitNonKernelFacility
-[on/<span style="font-style: italic;">off</span>]<br>
-equivalent to: PermitNonKernelFacility</li>
-<li><span style="font-weight: bold;"></span>$DebugPrintKernelSymbols
-[on/<b>off</b>]<br>
-Linux only, ignored on other platforms (but may be specified)</li>
-<li><b>$klogLocalIPIF</b> [interface name] - (available since 5.9.6) - if provided, the IP of the specified
-interface (e.g. "eth0") shall be used as fromhost-ip for imklog-originating messages.
-If this directive is not given OR the interface cannot be found (or has no IP address),
-the default of "127.0.0.1" is used.
-</li>
-<li>$klogSymbolLookup [on/<b>off</b>] --
-disables imklog kernel symbol translation (former klogd -x option). NOTE that
-this option is counter-productive on recent kernels (>= 2.6) because the
-kernel already does the symbol translation and this option breaks the information.<br>
-<b>This option is scheduled for removal, probably with version 4.x.</b> Do not use
-it except if you have a very good reason. If you have one, let us know
-because otherwise new versions will no longer support it.<br>
-Linux only, ignored on other platforms (but may be specified)</li>
-<li><b>$klogConsoleLogLevel</b> [<i>number</i>]
-<br>equivalent to: ConsoleLogLevel</li>
-<li><b>$klogUseSyscallInterface</b> [on/<b>off</b>]
--- former klogd -s option<br>
-Linux only, ignored on other platforms (but may be specified)</li>
-<li>$klogSymbolsTwice [on/<b>off</b>] --
-former klogd -2 option<br>
-Linux only, ignored on other platforms (but may be specified)<br style="font-weight: bold;">
-</li>
-<li><b>$klogParseKernelTimeStamp</b> [on/<b>off</b>]<br>
