# ActiveMQ Artemis Documentation

# 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 | 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

: Global Configuration Properties

## 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 add the following dependencies.

    <dependency>
       <groupId>org.jboss.logmanager</groupId>
       <artifactId>jboss-logmanager</artifactId>
       <version>1.5.3.Final</version>
    </dependency>
    <dependency>
       <groupId>org.apache.activemq</groupId>
       <artifactId>activemq-core-client</artifactId>
       <version>1.0.0.Final</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 value for this needs to be valid URL

The following is a typical `logging.properties for a client`

    # Root logger option
