Information on errors that have occurred in a CEP engine, such as insufficient memory and logging failures, is output to the engine log.
If some abnormality is detected in a CEP engine, this log can be analyzed in order to identify the cause.
Debug information for complex event processing rules that have been described is also output to the engine log, if the debug log listener has been set in the complex event processing rules.
The engine log is also used by logging as an event recording destination.
Refer to "6.1.6.3 Monitoring Abnormalities Using Logs" for information such as the output destination of the engine log.
