See "LogMessage" for additional details.
Cache Memory
Data is temporarily saved in cache memory and flushed to file system when at least one of the following conditions is true:
- temporary cache buffer is full
- an explicit dump procedure has been called
- 5 minutes cycle time has expired
Warning: data in cache memory will be lost if there is a power failure before data has been flushed to the file system.

From the "Events Buffer" you can configure the size of the audit buffer and activate the backup of the audit events when the buffer is full.
