Enabling logging and tracing in WebSphere® Application Server Liberty

We can set the logging levels and the output file for tracing operations for Application Center on the Liberty application server.

When we try to diagnose problems in the Application Center, it is important to be able to see the log messages. To print readable log messages in log files, you must specify the applicable settings.

To enable logging for IBM MobileFirst™ Platform Foundation, including Application Center, with level FINEST(equivalent to ALL), add a line to the server.xml file. For example:

<logging traceSpecification="com.ibm.puremeap.*=all:com.ibm.worklight.*=all:com.worklight.*=all"/>

In this example, multiple entries of a package and its logging level are separated by a colon (:).

The traces are sent to a file called trace.log, not to messages.log or to console.log.

For more information, see Liberty profile: Logging and Trace.
