Logging

Apache ActiveMQ Artemis uses the JBoss Logging framework to do its logging and is configurable via the logging.properties file found in the configuration directories. This is configured by Default to log to both the console and to a file.

There are 6 loggers available which are as follows:

Logger Description
org.jboss.logging Logs any calls not handled by the Apache ActiveMQ Artemis loggers
org.apache.activemq.artemis.core.server Logs the core server
org.apache.activemq.artemis.utils Logs utility calls
org.apache.activemq.artemis.journal Logs Journal calls
org.apache.activemq.artemis.jms Logs JMS calls
org.apache.activemq.artemis.integration.bootstrap Logs bootstrap calls

Logging in a client or with an Embedded server

Firstly, if you want to enable logging on the client side you need to include the JBoss logging jars in your library. If you are using Maven the simplest way is to use the "all" client jar.

<dependency>
   <groupId>org.jboss.logmanager</groupId>
   <artifactId>jboss-logmanager</artifactId>
   <version>2.0.3.Final</version>
</dependency>
<dependency>
   <groupId>org.apache.activemq</groupId>
   <artifactId>activemq-core-client</artifactId>
   <version>2.5.0</version>
</dependency>

There are 2 properties you need to set when starting your java program, the first is to set the Log Manager to use the JBoss Log Manager, this is done by setting the -Djava.util.logging.manager property i.e. -Djava.util.logging.manager=org.jboss.logmanager.LogManager

The second is to set the location of the logging.properties file to use, this is done via the -Dlogging.configuration for instance -Dlogging.configuration=file:///home/user/projects/myProject/logging.properties.

Note:

The logging.configuration system property needs to be valid URL

The following is a typical logging.properties for a client
