Logs
ART uses the Logback library for application logging. By default, application logging is done to standard output and includes logging on errors, warnings and information messages. The location of the logs or the amount of logging generated can be modified by making appropriate configuration changes to the WEB-INF\classes\logback.xml file. Changes made to the logging configuration e.g. changing certain logging levels from "info" to "debug" automatically take effect after the configured scanPeriod. Scan period values can be specified as milliseconds, seconds, minutes or hours. See http://logback.qos.ch/manual/configuration.html for more details.
In addition to being available on the application server's standard output log files, e.g stdout.log or catalina.log on Tomcat, application logs can also be viewed from within ART. This means that you don't need to have access to the application server machine in order to view application logs.
Application logs can be viewed from the View | Logs menu. New logs are added to the bottom and you'll need to refresh the page to view them. Also note that this page doesn't display all the logs ever generated by the application, only the most recent ones.
Configuring Loggers
To add or modify logging for a particular class or package, you can modify the logback.xml file and add the logger there or alternatively, use the Configure | Loggers menu to add the logger. Loggers added from the application interface will be lost when the application is restarted.
