How to enable access logging for JBoss EAP 6?

Solution Verified - Updated -

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 6.x

Issue

  • Activate instant http request access logging to file for the web subsystem
  • Access logs not generating.
  • Convert this configuration from an earlier version

    <Valve className="org.apache.catalina.valves.AccessLogValve" 
                    prefix="localhost_access_log." suffix=".log"
                    pattern="common" directory="${jboss.server.log.dir}" 
                    resolveHosts="false" />
    
  • Access log file shows false2015-11-11

  • Create access logs with different name format.

By default there is no web logging enabled. In JBoss EAP 6, access logging can be configured per web application, or by virtual-server of the web subsystem.

Per Web Application Setting

Configure AccessLogValve setting in WEB-INF/jboss-web.xml to enable access logging for a web application. For example:

    <jboss-web>
        <valve>
            <class-name>org.apache.catalina.valves.AccessLogValve</class-name>
            <param>
                <param-name>prefix</param-name>
                <param-value>myapp_access_log.</param-value>
            </param>
            <param>
                <param-name>suffix</param-name>
                <param-value>.log</param-value>
            </param>
            <param>
                <param-name>fileDateFormat</param-name>
                <!-- use pattern letters defined in SimpleDateFormat.
                    This fileDateFormat setting affects to log rotation cycle
                -->
                <!-- default setting: daily -->
                <param-value>yyyy-MM-dd</param-value>
                <!-- hourly
                <param-value>yyyy-MM-dd.HH</param-value>
                -->
            </param>
            <param>
                <param-name>pattern</param-name>
                <!--  use constant text or replacement strings defined in 
                    http://docs.jboss.org/jbossweb/7.0.x/config/valve.html to pattern tokens.
                -->
                <!-- default setting: common (%h %l %u %t "%r" %s %b) -->
                <param-value>common</param-value>
                <!-- combined (%h %l %u %t "%r" %s %b "%{Referer}i" "%{User-Agent}i") 
                <param-value>combined</param-value>
                -->            
                <!-- combined + response time
                <param-value>%h %l %u %t %r %s %b %{Referer}i %{User-Agent}i TimeTaken: %T </param-value>
                -->
                <!-- combined + Session ID + Response time 
                <param-value>%h %l %u %t %r %s %b %{Referer}i %{User-Agent}i SessionID: %S TimeTaken: %T</param-value>
                -->
            </param>
            <param>
                <param-name>directory</param-name>
                <param-value>${jboss.server.log.dir}</param-value>
            </param>
            <param>
                <param-name>resolveHosts</param-name>
                <param-value>false</param-value>
            </param>
        </valve>
    </jboss-web>

Note: This can be enabled/disabled by changing the above config and redeploying the application.

Via WebSubsystem

Run the following CLI commands standalone.xml. Prefix all commands with /profile=MYPROFILE for domain.xml. Restart the server for this to take effect.

    /subsystem=web/virtual-server=default-host/configuration=access-log:add()
    /subsystem=web/virtual-server=default-host/configuration=access-log:write-attribute(name="pattern",value="%h %l %u %t %r %s %b %{Referer}i %{User-Agent}i Cookie: %{COOKIE}i Set-Cookie: %{SET-COOKIE}o SessionID: %S Thread: %I TimeTaken: %T ")
    /subsystem=web/virtual-server=default-host/configuration=access-log:write-attribute(name="prefix",value="access_log_")

Note Don't leave off the prefix because it will end up adding false.

This will result in:

    <access-log pattern="%h %l %u %t %r %s %b %{Referer}i %{User-Agent}i Cookie: %{COOKIE}i Set-Cookie: %{SET-COOKIE}o SessionID: %S Thread: %I TimeTaken: %T" prefix="access_log_"/>

By default, access logging is output under ${jboss.server.log.dir}/default-host i.e. under $JBOSS_HOME/standalone/log/default-home, but it's possible to change the directory:

    /subsystem=web/virtual-server=default-host/configuration=access-log/setting=directory:add()
    /subsystem=web/virtual-server=default-host/configuration=access-log/setting=directory:write-attribute(name="path",value="./")
    /subsystem=web/virtual-server=default-host/configuration=access-log/setting=directory:write-attribute(name="relative-to",value="jboss.server.log.dir")

This will result in the following XML:

    <paths>
        <path name="my.log.dir" path="/mnt/log/jboss"/>
    </paths>
    ...(snip)...
    <subsystem xmlns="urn:jboss:domain:web:1.2" 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="%h %l %u %t %r %s %b %{Referer}i %{User-Agent}i Cookie: %{COOKIE}i Set-Cookie %{SET-COOKIE}o SessionID: %S Thread: %I TimeTaken: %T" prefix="access_log_">
                <directory path="${jboss.server.name}-accessLog" relative-to="my.log.dir" />
            </access-log>
        </virtual-server>
    </subsystem>

This would output access log under /mnt/log/jboss/my-access-log, please configure the following <directory> and <paths> setting. Leave off the directory settings if the default path is required.

Since JBoss Web is based on Apache Catalina, check AccessLogValvepage in Apache Tomcat documentation for more arguments to use.
