Logs

For the METS-R SIM, the main logger is initialized in ContextCreator.java. Log messages are written to both stdout and a log file named mets_r.log.

Logging levels in increasing order of severity are given below.

• ALL: All levels including custom levels.

• DEBUG: Designates fine-grained informational events that are most useful to debug an application.

• INFO: Designates informational messages that highlight the progress of the application at a coarse-grained level.

• WARN: Designates potentially harmful situations.

• ERROR: Designates error events that might still allow the application to continue running.

• FATAL: Designates very severe error events that will presumably lead the application to abort.

• OFF: The highest possible rank and is intended to turn off logging.

Desired levels can be set in log4j.properties file located in the root directory.
