<p>Implementation of a Logstash codec for the ArcSight Common Event Format (CEF)
Based on Revision 20 of Implementing ArcSight CEF, dated from June 05, 2013
<a href="https://community.saas.hpe.com/dcvta86296/attachments/dcvta86296/connector-documentation/1116/1/CommonEventFormatv23.pdf" class="ulink" target="_top">https://community.saas.hpe.com/dcvta86296/attachments/dcvta86296/connector-documentation/1116/1/CommonEventFormatv23.pdf</a></p>
<p>If this codec receives a payload from an input that is not a valid CEF message, then it will
produce an event with the payload as the <em>message</em> field and a <em>_cefparsefailure</em> tag.</p>

<p>If your input puts a delimiter between each CEF event, you’ll want to set
this to be that delimiter.</p>
<p>For example, with the TCP input, you probably want to put this:</p>
<pre class="literallayout">input {
tcp {
codec => cef { delimiter => "\r\n" }
# ...
}
}</pre>
<p>This setting allows the following character sequences to have special meaning:</p>
