The Universal Messaging server log is located at Software AG_directory\UniversalMessaging\server\instanceName\nirvana.log. If any issues occur, first check the nirvana.log file of the realm. This is often the most descriptive and helpful source for problem analysis.

You can change the logging level for a realm in the Logging Config group on the Config tab in Enterprise Manager. The fLoggerLevel property specifies the level of logging to be used. Lower numbers here produce more verbose and detailed log messages.
