8.1 Enterprise Message API Logger Usage
The Enterprise Message API provides a logging mechanism useful for debugging runtime issues. In the default configuration, Enterprise Message API is set to log significant events encountered during runtime and direct logging output to a file. If needed, you can turn off logging, or direct its output to stdout. Additionally, applications can configure the logging level at which the Enterprise Message API logs event (to log every event, only error events, or nothing). For further details on managing and configuring the EMS logging function, refer to the Enterprise Message API Configuration Guide.
