    How to generate server.log in custom folder location in wildfly-8.2.0.Final

    sridhar thiyagarajan Novice



      I am facing a problem regarding server.log file generation in Wildfly-8.2.0.Final AS.


      Below is the size-rotating-file-handler definition used in logging subsystem <subsystem xmlns="urn:jboss:domain:logging:2.0"> of standalone-full-ha.xml.



          <size-rotating-file-handler name="FILE" autoflush="false">

                <level name="DEBUG"/>

                <file relative-to="jboss.server.log.dir" path="server.log"/>

                <rotate-size value="500k"/>

                <max-backup-index value="5"/>

                <append value="true"/>



      The above works fine and it generates server.log in ${WILDFLY_HOME}/standalone/log folder. I would like to have a custom location for server.log and hence, modified the path attribute to contain the complete custom path and removed relative-to attribute as shown below.


          <file path="D:/wildfly-8.2.0.Final/standalone/log/server.log"/>


      But, with the above changes, server.log is getting generated in custom location but facing the below problems:


      - log statements are getting generated without date in it. for e.g.:


      12:16:11,800 INFO  [org.jboss.as] (MSC service thread 1-7) JBAS015899: WildFly 8.2.0.Final "Tweek" starting


      - Complete logs are not observed in the log file and for example, "server is started..." will be the last line and a quarter of the log statements are not printed.


      Please help me.

          Try setting autoflush to true. It's likely just being buffered and not written. As for the date not being printed you'll need to use a formatter to get date. Assuming the default configuration there should be a patter-formatter called PATTERN which will log the full timestamp.

          /subsystem=logging/size-rotating-file-handler=FILE:write-attribute(name=named-formatter, value=PATTERN)


          Also note you can override the jboss.server.log.dir by setting the system property in the JAVA_OPTS. Or you can configure a custom path and use that in the relative-to.
