How to configure WildFly 8.2 to use AccessLogHandler

I have found that there is a handler io.undertow.server.handlers.accesslog.AccessLogHandler that can log http access.

However I am not able to configure it so it will produce any log messages.

Here is a code snippet from my standalone.xml:

<filter class-name="io.undertow.server.handlers.accesslog.AccessLogHandler" name="access-log-handler" module="io.undertow.core">
    <param name="formatString" value="common"/>
    <param name="accessLogReceiver" value="io.undertow.server.handlers.accesslog.JBossLoggingAccessLogReceiver"/>
</filter>

My question is how to configure that handler so it will start producing log messages.

no need to add custom filter for access log. All you need is to configure access log in subsystem itself. This would be an example: 

<host name="default-host" >
    <location name="/" handler="welcome-content">
     ....    
    <access-log />
</host>

which will by default log in to log folder with prefix access_.log

you can also customize various things, from xsd:

<xs:attribute name="pattern" use="optional" type="xs:string" default="common"/>
<xs:attribute name="worker" use="optional" type="xs:string" default="default"/>
<xs:attribute name="directory" use="optional" type="xs:string" default="${jboss.server.log.dir}"/>
<xs:attribute name="relative-to" use="optional" type="xs:string" />
<xs:attribute name="prefix" use="optional" type="xs:string" default="access_log"/>
<xs:attribute name="suffix" use="optional" type="xs:string" default=".log"/>

I missed to add this xml snippet (StackOverflow):

<host name="default-host" >
     .....
     <filter-ref name="access-log-handler"/>
</host>

And then I got this:

Caused by: java.lang.NoSuchMethodException: io.undertow.server.handlers.accesslog.AccessLogHandler.<init>(io.undertow.server.HttpHandler)"}}

Which is a known bug: see this, or this

It is possible to use jboss-cli to add a handler and see how the standalone.xml changed:

/subsystem=undertow/configuration=filter/custom-filter=access-log-handler:add(class-name=io.undertow.server.handlers.accesslog.AccessLogHandler, module=io.undertow.core)
/subsystem=undertow/server=default-server/host=default-host/filter-ref=access-log-handler:add
