<h1>UDP Syslog Input Module</h1>
|
|
<p><b>Module Name: imudp</b></p>
|
|
<p><b>Author: </b>Rainer Gerhards <rgerhards@adiscon.com></p>
|
|
<p><b>Multi-Ruleset Support: </b>since 5.3.2
|
|
<p><b>Description</b>:</p>
|
|
<p>Provides the ability to receive syslog messages via UDP.
|
|
<p>Multiple receivers may be configured by specifying
|
|
$UDPServerRun multiple times.
|
|
</p>
|
|
<p><b>Configuration Directives</b>:</p>
|
|
<ul>
|
|
<li>$UDPServerAddress <IP><br>
|
|
local IP address (or name) the UDP listens should bind to</li>
|
|
<li>$UDPServerRun <port><br>
|
|
former -r<port> option, default 514, start UDP server on this
|
|
port, "*" means all addresses</li>
|
|
<li>$UDPServerTimeRequery <nbr-of-times><br>
|
|
this is a performance
|
|
optimization. Getting the system time is very costly. With this setting, imudp can
|
|
be instructed to obtain the precise time only once every n-times. This logic is
|
|
only activated if messages come in at a very fast rate, so doing less frequent
|
|
time calls should usually be acceptable. The default value is two, because we have
|
|
seen that even without optimization the kernel often returns twice the identical time.
|
|
You can set this value as high as you like, but do so at your own risk. The higher
|
|
the value, the less precise the timestamp.
|
|
<li>$InputUDPServerBindRuleset <ruleset><br>
|
|
Binds the listener to a specific <a href="multi_ruleset.html">ruleset</a>.</li>
|
|
</ul>
