Overview

This page documents the configuration of the Undertow AccessLogHandler. The handler generates log entries for each request. The handler can log any attributed that is provided with the ExchangeAttribute mechanism. The most common are presented below in the Log Patterns section.

<subsystem xmlns="urn:jboss:domain:undertow:3.0">

   ...

   <server name="default-server">
      ...
      <host name="default-host" alias="localhost">
         <location name="/" .../>
         <access-log/>
         ...
      </host>
   </server>

   <servlet-container .../>

   ...

 </subsystem>
