Enable Access Logs in JBoss 7

JBoss 7 is slightly different than earlier version JBoss 5 or 6. The procedure to enable access logs in JBoss 7 is also changed and you must be familiar on how to enable access logs in JBoss 7.

  • Go to JBoss/standalone/configuration folder
  • Add following in standalone.xml, look for domain:web syntax and ensure to add before closing </virtual-server> tag.
<access-log pattern="%a %t %H %p %U %s %S %T" rotate="true">
<directory path="." relative-to="jboss.server.log.dir"/>
</access-log>

Ex:

<subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="false">             
<connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/> 
<virtual-server name="default-host" enable-welcome-root="true"> 
<alias name="localhost"/> 
<alias name="example.com"/> 
<access-log pattern="%a %t %H %p %U %s %S %T" rotate="true"> 
<directory path="." relative-to="jboss.server.log.dir"/> 
</access-log> 
</virtual-server> 
</subsystem>
  • Restart JBoss 7 server and verify the access logs under log folder.

You may refer following for valve patterns to capture in the access log.

%B– Bytes sent, excluding HTTP headers
%h– Remote host name (or IP address if resolveHostsis false)
%H– Request protocol
%l– Remote logical username from identd (always returns ‘-‘)
%m– Request method (GET, POST, etc.)
%p– Local port on which this request was received
%q– Query string (prepended with a ‘?’ if it exists)
%r– First line of the request (method and request URI)
%s– HTTP status code of the response
%S– User session ID
%t– Date and time, in Common Log Format
%u– Remote user that was authenticated (if any), else ‘-‘
%U– Requested URL path
%v– Local server name
%D– Time is taken to process the request, in millis
%T– Time is taken to process the request, in seconds
%I– current request thread name (can compare later with stack traces)
