How to configure WildFly 8.2 to use AccessLogHandler - jboss

Question

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.

Answer 1

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"/>

Answer 2

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
