Customizing logging format in Jboss 7 AS

[dkumaran]

Hi

In our application we need to customize the logging format Please let us know how can we customize the Jboss logging format. we found that in in "standalone.xml" we are defining the logging subsystem.

  <subsystem xmlns="urn:jboss:domain:logging:1.0">

            <console-handler name="CONSOLE" autoflush="true">

                <level name="INFO"/>

                <formatter>

                    <pattern-formatter pattern="%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n"/>

                </formatter>

            </console-handler>

What are the other types of formatting available in jboss logging, and how can we customize ?

[prasad.deshpande]

Formatting is same as log4j-style as defined in documentation of PatternLayout class of log4j, except that jboss pattern doesn't not accept "M" & "L" conversion characters.

see API docs for org.jboss.logmanager.formatters.FormatStringParser class & http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html for patterns.

i just want to reframe my question here like this..

i have a class "CustomLayout" which extended from PatternLayout  and i want to use the same here in JBoss 7AS Is that possible

In a log4j.xml we can give the same as below

<appender name="R" class="org.apache.log4j.RollingFileAppender">

        <param name="file" value="d:/server/log/samplelog4j.log" />

        <param name="MaxFileSize" value="100KB" />

        <param name="MaxBackupIndex" value="10" />

         <layout class="com.learning.log4j.CustomLayout">

            <param name="ConversionPattern" value="[%r,%c{1},%t] %m%n"/>

        </layout>

    </appender>

So in Jboss 7 AS can i specify in standalone.xml

<subsystem xmlns="urn:jboss:domain:logging:1.0">

            <console-handler name="CONSOLE" autoflush="true">

                <level name="INFO"/>

                <formatter>

                    <pattern-formatter class="com.learning.log4j.CustomLayout" pattern="%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n"/>

                </formatter>

            </console-handler>

You don't have to configure logging in the standalone.xml. If you are using log4j, then just package the log4j.xml and the log4j and your custom layout class to get it working.

Jai,,

have you tried the same in JBoss 7 AS,  i have tried a sample application with log4j.xml. but i couldn't see the app.log file,  the source of the sample application is attached in the discussion thread..    

     http://community.jboss.org/thread/171287?tstart=0

if you have some working samples can you share with us. ?

I haven't. But one other user has http://community.jboss.org/message/621302#621302

All you have to do is to make available your log4j.xml in application classpath. Make sure that your log4j.xml is found by application, most of the time that is the problem. If you are not sure, then just bundle it in jar file & drop that jar in your lib directory (If your application is packaged as EAR then ear/lib, if it's WAR, then in WEB-INF/lib or just drop log4j.xml in WEB-INF/classes directory).

I'll take a look at your attached sample application (http://community.jboss.org/thread/171287?tstart=0) to see what's going on.

i could able to add the customized Layout and it's working  with your reference.

Thanks  a lot.

Didn't want to start a new thread since my question is related.

But if M and L can't be used how can i get the method and line number? Is that possible or would i need to switch and use log4j?

Also, in the pattern corrently defaulted pattern="%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n" what does the E mean. 

Is there documentation on this?  I checked the one for log4j patternlayout and there a some difference.  like s here is the message which was mentioned in the JBoss 7 config admin book.

Thanks

Michael,

Both %M and %L should work in a pattern should work. There is no reason to use log4j, the JBoss Log Manager will recognize the format. This pattern "%d{HH:mm:ss,SSS} %-5p [%c.%M:%L] (%t) %s%E%n" works for me.

14:19:06,931 INFO  [test.testConfig:71] (main) Test message should show up on the console.

The %E in the default pattern is for a Throwable. Meaning it will print the stacktrace if an exception is being logged.

No, JBoss logger has different output compared to log4j PatternLayout:

Try [%20c]  [%-20c]  [%.20c]  [%10.20c]  [%-10.20c] with log4j and JBoss logger and you see completely different output (JBoss logger does not support all log4j patterns/formatting rules)

[jamezp]

For the most part JBoss Log Manager's pattern formatter should parse most log4j style formats. If there are some specific formats you would like to be parsed, feel free to file a detailed JIRA of the specific deficiency.

Can i provide the timezone in the customized formatter (   %d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n  )?

and/or if i want to change the time (to be output to log file), to some other timezone (to match other servers time), how can i do that.

[jamezp]

It just uses the java.text.SimpleDateFormat so yes. Just use z or Z options.

Example:

%d{HH:mm:ss,SSS Z} %-5p [%c] (%t) %s%E%n
