+== Logging External Components
+
+Logback can also be configured to log any other, external components APEX is using, if they are using the common logging framework.
+
+For instance, the context component of APEX is using __Infinispan__ and one can add a logger for this external component.
+The following example adds a logger for __Infinispan__ using the standard output appender.
+
+[source%nowrap,xml]
+----
+<logger name="org.infinispan" level="INFO" additivity="false">
+  <appender-ref ref="STDOUT" />
+</logger>
+----
+
+Another example is Apache Zookeeper.
+The following example adds a logger for Zookeeper using the standard outout appender.
+
+[source%nowrap,xml]
+----
+<logger name="org.apache.zookeeper.ClientCnxn" level="INFO" additivity="false">
+  <appender-ref ref="STDOUT" />
+</logger>
+----
