GlassFish 3: how do you change the (default) logging format?

java logging glassfish glassfish-3 slf4j

The question originated from here: http://www.java.net/forum/topic/glassfish/glassfish/configuring-glassfish-logging-format - without an answer.

The default GlassFish 3 logging format is very annoying, much too long.

[#|2012-03-02T09:22:03.165+0100|SEVERE|glassfish3.1.2|javax.enterprise.system.std.com.sun.enterprise.server.logging|_ThreadID=113;_ThreadName=AWT-EventQueue-0;| MESSAGE... ]

This is just a horrible default IMO. The docs just explain all the fields, but not how to change the format: http://docs.oracle.com/cd/E18930_01/html/821-2416/abluk.html

Note, that I deploy SLF4J along with my webapp which should pick up the format as well.

How do you change the logging format?

FYI:

The links here are outdated: Install log formater in glassfish...

The question here hasn't been answered: How to configure GlassFish logging to show milliseconds in timestamps?...

The posting here resulted in nothing: http://www.java.net/forum/topic/glassfish/glassfish/cant-seem-configure-...

It looks like GlassFish logging configuration is an issue of its own. Can anybody help?

The solution seems to be the first SO posting here: Install log formater in glassfish

I've hacked together a simple log formatter (adjust at will):

import java.io.PrintWriter;
import java.io.StringWriter;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.LogRecord;
import java.util.logging.SimpleFormatter;

public class JBossAS7LikeFormatter extends SimpleFormatter
{
    private final String nl = System.getProperty("line.separator");
    private final DateFormat df = new SimpleDateFormat("HH:mm:ss,SSS");

    @Override
    public synchronized String format(LogRecord lr)
    {
        StringBuffer sb = new StringBuffer();

        // time only
        Date dt = new Date();
        dt.setTime(lr.getMillis());

        sb.append(df.format(dt));
        sb.append(" ");

        // level (longest is "WARNING" = 7 chars, space fill for level output)
        String level = lr.getLevel().getName();

        int numSpaces = 7 - level.length();

        sb.append(level);

        for ( int i = 0 ; i < numSpaces + 1 ; i++ )
        {
            sb.append(" ");
        }

        // package
        sb.append("[");
        sb.append(lr.getSourceClassName());
        sb.append("] ");

        // thread (name?)
        sb.append("(");
        sb.append(lr.getThreadID());
        sb.append(") ");

        // message
        sb.append(formatMessage(lr));
        sb.append(nl);

        // optional stack trace
        if ( lr.getThrown() != null )
        {
            try
            {
                StringWriter sw = new StringWriter();
                PrintWriter pw = new PrintWriter(sw);
                lr.getThrown().printStackTrace(pw);
                pw.close();
                sb.append(sw.toString());
            }
            catch ( Exception e )
            {
            }
        }

        return sb.toString();
    }

}

It even fixes the double newline problem on Windows machines.

I got this to work by putting the JAR into domain/lib/ext at first, but for newer tries, whatever the reason is, I only keep getting a ClassNotFoundException now:

Completed shutdown of GlassFish runtime
Command start-domain failed.
The DAS was stopped.

I saw the new format for a few tries, but the it stopped to work - strange.

I've attached the JAR as is in my original GlassFish forum post. I've basically just used my ZIP tool and renamed it to JAR, but this shouldn't be a problem (?). If anybody gets it to work (again) please let me know.

Note: I'm using the GlassFish plugin to start/stop the server, don't know if this could be an issue.

Please continue any discussions in the GlassFish forum here: http://www.java.net/forum/topic/glassfish/glassfish/configuring-glassfish-logging-format

PS: sorry I needed to post the stack trace here as the GF forum is somewhat broken.

UPDATE:

Extending java.util.logging.SimpleFormatter did the trick. GlassFish now produces log entries like:

12:13:02,400 INFO    [com.sun.enterprise.web.WebContainer] (1) WEB0172: Virtual server [server] loaded default web module []
12:13:07,700 INFO    [org.hibernate.validator.util.Version] (1) Hibernate Validator 4.2.0.Final

12:13:08,920 WARNING [null] (1) JMX MBeanServer in use: [com.sun.jmx.mbeanserver.JmxMBeanServer@2f740f7e] from index [1]

Again, on Windows: no double newlines.
