Configuring gmt timestamp on log4j

[diegosdias]

I am trying to configure my logs with GMT timetamps instead of local timestamps.

My appender is

<appender name="FILE" class="org.jboss.logging.appender.DailyRollingFileAppender">
      <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
      <param name="File" value="${jboss.server.log.dir}/server.log"/>
      <param name="Append" value="true"/>

      <!-- Rollover at midnight each day -->
      <param name="DatePattern" value="'.'yyyy-MM-dd"/>

      <!-- Rollover at the top of each hour
      <param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
      -->

      <layout class="org.apache.log4j.PatternLayout">
         <!-- The default pattern: Date Priority [Category] Message\n -->
         <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>

         <!-- The full pattern: Date MS Priority [Category] (Thread:NDC) Message\n
         <param name="ConversionPattern" value="%d %-5r %-5p [%c] (%t:%x) %m%n"/>
          -->
      </layout>
   </appender>

I have tried changing

<param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>

to

<param name="ConversionPattern" value="%dGMT %-5p [%c] %m%n"/> or

<param name="ConversionPattern" value="%d{GMT} %-5p [%c] %m%n"/>

but both didn't work.

How can I do it just changing the conf of jboss-log4j.xml?

Hi Diego,

you need a special PatternLayout-Class, it org.apache.log4j.EnhancedPatternLayout. With this one you can use GMT Timestamps. To get this working, you need to download the log4j-extras from http://logging.apache.org/log4j/companions/extras/download.html. Further Doc's at http://logging.apache.org/log4j/companions/extras/apidocs/org/apache/log4j/EnhancedPatternLayout.html

Best regards,

Mark

Try adding this to the appender:

<appender ...>

  . . .

  <layout class="org.apache.log4j.TTCCLayout">

    <param name="TimeZone" value="GMT" />

  </layout>

<appender>
