Chapter 5. Configuring Logging

You can configure logging for the messaging-activemq subsystem by adding a log category in the JBoss EAP logging subsystem for org.apache.activemq and setting the desired log level. You can also configure a log handler for the category to configure how the log messages are recorded.

To see more information in the logs regarding XA transactions, change the log level of the com.arjuna category to a more verbose setting such as TRACE or DEBUG.

For more information on logging, including configuration for categories and other options, see the section on logging in the JBoss EAP Configuration Guide.

Configuring a Client for Logging

Configure messaging clients by following these steps.

  1. Download dependencies to the JBoss JMS client and log manager.

    If you are using Maven, add the following dependencies to your pom.xml file: 

    <dependencies>
  ...
  <dependency>
     <groupId>org.jboss.logmanager</groupId>
     <artifactId>jboss-logmanager</artifactId>
     <version>1.5.3.Final</version>
  </dependency>
  <dependency>
      <groupId>org.jboss.eap</groupId>
      <artifactId>wildfly-jms-client-bom</artifactId>
      <type>pom</type>
  </dependency>
  ...
</dependencies>

    For more information, see the section on using Maven with JBoss EAP in the JBoss EAP Development Guide.

  2. Create a properties file for the logger. Name it logging.properties and save it to a known location. Below is an example properties file. See the section on logging in the JBoss EAP Development Guide for more information on configuring logging options on the client side. 

    # Root logger option
loggers=org.jboss.logging,org.apache.activemq.artemis.core.server,org.apache.activemq.artemis.utils,org.apache.activemq.artemis.journal,org.apache.activemq.artemis.jms,org.apache.activemq.artemis.ra

# Root logger level
logger.level=INFO
# Apache ActiveMQ Artemis logger levels
logger.org.apache.activemq.artemis.jms.level=INFO
logger.org.apache.activemq.artemis.journal.level=INFO
logger.org.apache.activemq.artemis.utils.level=INFO
logger.org.apache.activemq.artemis.core.server.level=INFO

# Root logger handlers
logger.handlers=FILE

# File handler configuration
handler.FILE=org.jboss.logmanager.handlers.FileHandler
handler.FILE.level=FINE
handler.FILE.properties=autoFlush,fileName
handler.FILE.autoFlush=true
handler.FILE.fileName=activemq.log
handler.FILE.formatter=PATTERN

# Formatter pattern configuration
formatter.PATTERN=org.jboss.logmanager.formatters.PatternFormatter
formatter.PATTERN.properties=pattern
formatter.PATTERN.pattern=%d{HH:mm:ss,SSS} %-5p [%c] %s%E%n

  3. Start the client with the expected parameters. When starting your client code using the java command, add the following parameters:

    1. Add the JBoss client and logger JARs to the class path: 

      -cp /PATH/TO/jboss-client.jar:/PATH/TO/jboss-logmanager.jar

    2. Enable the JBoss logging manager: 

      -Djava.util.logging.manager=org.jboss.logmanager.LogManager
      Copy to Clipboard Toggle word wrap

    3. Set the location of the logging properties file: 

      -Dlogging.configuration=/PATH/TO/logging.properties
      Copy to Clipboard Toggle word wrap

    The full command to start the client will look something like the following example: 

$ java -Djava.util.logging.manager=org.jboss.logmanager.LogManager -Dlogging.configuration=/PATH/TO/logging.properties -cp /PATH/TO/jboss-client.jar:/PATH/TO/jboss-logmanager.jar org.example.MyClient
