The Alert Console displays all exceptions logged by the Service Definition Framework. It also enables you to reprocess exceptions that occur in transactions configured to be asynchronous. When using a database or queue, calls are asynchronous.
The Service Definition Framework uses the log4j utility for logging exception information. The log4j utility writes both trace and debug information to a log file. You can configure the logger to send different categories of messages to different destinations. Categories are organized hierarchically, which permits inheritance. Each category can be configured with a priority indicating a severity level. If a category is not configured with a priority, it inherits the priority of its closest ancestor with an assigned priority.
All exceptions that occur during an API call or during use of an event handler are logged.
